DAVID BROWN RADICON SERIES L CATALOGUE REV. 01
BACKGROUND
The Series L range of helical and bevel helical gear units are designed to meet the most arduous of power
transmission application needs. Reliable and efficient in operation, they provide a cost-effective solution to all our
customers’ needs. Designed to David Brown Radicon’s long established standard of quality these quiet running
units provide exceptional levels of performance, versatility and life expectancy to meet the demanding
requirements of modern industry.
The Radicon story is above all a constant drive for perfection. It starts more than a century ago and tells of total
dedication and commitment to the development of gear technology. Series L is a part of that story.
The David Brown gear organisation was founded in 1860. It produced the first commercial worm gearbox in 1903
and so helped to establish a marketplace it has led ever since.
The organisation rapidly became a master of its craft. Notable credits include the introduction of a patented involute
helicoidal worm thread form in 1912, followed later by the development of phosphor bronze materials for
wormwheels which have become a standard throughout the industry.
The division got its title in 1933 with the introduction of worm gearbox units with cooling fans and ribbed casings.
This brought unprecedented performance in the dissipation of generated heat and it gave rise to the name Radicon;
RADIation Induction and CONvection. That name has since become respected in gear circles throughout the world.
The passage of time has seen constant refinements accumulating expertise and scientific progress but the
organisation’s pioneering spirit remains unchanged as technological barriers are crossed one after another. The
development of the Series L helical and bevel helical geared units is another example of David Brown South Africa’s
superior technical expertise. Series L gear units are available in-line and right-angle versions in single, double, triple
and quadruple reduction gear stages having a maximum power capacity exceeding 5,500 kW.
Designed in South Africa for southern hemisphere conditions, the Series L benefits from the “design-formanufacture” philosophy which ensures optimum product for the applicable and minimum spares requirements.
This in turn provides considerable economies of production whilst maintaining the highest standard of component
integrity. Featuring carburized, hardened and profile ground helical gears, highly efficient and quiet running
characteristics are assured. The gear units are available in a wide range of ratios from 1,22:1 to 1000:1. Units can be
offered in horizontal mounting positions or alternatively vertical mounting. Specially designed units are available for
cooling tower applications or heavy duty stirrer applications. All units are also available with hollow bores for output
shaft mounting. The product is further enhanced by a high power-to-weight ratio and low volume, enabling
installation in the most difficult situations.
The use of high quality materials also provides assurance of long life and reliability in operation in the most extreme
environmental conditions.

UNIT RATINGS-MECHANICAL
Mechanical Ratings and Service Factors Fm and Fs
Mechanical ratings measure capacity in terms of life and/or strength, assuming 10hr/day continuous operation under
uniform load conditions.
Catalogue ratings allow 100% overload at start, braking or momentarily during operation up to 10 times per day.
The unit selected must therefore have a catalogue rating at least equal to half the maximum load overload.
The Mechanical Service Factor Fm (Table 1) is used to modify the actual load according to daily operating time, and the
type of loading. Required mechanical power rating P(mech)= absorbed power x Fm.
Load characteristics for a wide range of applications are detailed in table 3 on page 5, which are used in deciding the
appropriate Service Factor Fm from table 1.
If loading can be calculated, or accurately measured, actual loads should be used instead of modifying using Fm.
For units subjected to torque reversal or frequent stop/start overloads in excess of 10 times per day, the following check
should be made
Gear unit input power capacity (kW) ≥ Tm x Fs x n
2 x 9550
Where Tm =
n =
Fs =
motor starting torque (Nm) or rating of torque limiting device, fluid coupling etc
input speed (rpm)
Number of starts factor (see table 2)
For applications where high inertia loads are involved e.g. crane travel drives, slewing motion etc, or when units are to
operate in extremely dusty or moist/humid atmospheres, unit selection should be referred to our Application Engineers.

UNIT RATINGS- THERMAL
Thermal Ratings and Service Factors
The thermal ratings are a measure of the gear units ability to dissipate heat. If they are exceeded the lubricant may
overheat and breakdown, resulting in gear failure.
The thermal ratings are given on page 21. The following choices are available:
i.
No additional cooling.
ii.
Unit fitted with cooling fan.
Catalogue thermal limitations are based on the unit operating continuously in an environment with an ambient
temperature equal to 30 °C and in a horizontal mounting position. The thermal rating is affected by the ambient
temperature, duration of running per hour, altitude and operating are. To account for these varying conditions, the service
factors given in tables 4, 5, 6 and 7 should be applied as follows:Ptherm = Absorbed Power
Ft x Fd x Fh x Fv
Where
Ptherm =

4. Determine Size of Gear Unit
Required
Unit input power capacity ≥ Pmech
Refer to rating tables, Input speed=
1450rpm, therefore to page 19.
Mechanical input power capacity must
be equal or more then required
mechanical input power capacity
(Pmech). Required Pmech = 98.75kW.
At a ratio of 25.6:1 a TRA45 has a
mechanical input power capacity of
102kW. Therefore the unit is
acceptable.
If the unit is subjected to torque
reversal or frequent stop/starts the
input power capacity must be checked
in accordance with the formula on page

LUBRICATION
All Series L gear units are dispatched without oil (a warning label is attached), and therefore filled by the client. The
recommended oils are listed in table 11 on page 11 of this catalogue. The oil change period can be found in the installation
and maintenance manual of all Series L gear units.
The approximate quantity of oil required is give in table 8, but the unit should always be filled to the level marked on the
dipstick or any other level indicator fitted (sight glass etc). Warning: Do not overfill the unit as this may cause leakage and
overheating.
Where possible run the unit without load for a short time to circulate the lubrication thoroughly, then stop the unit and
recheck the oil level after allowing the unit to stand for 10 minutes and if necessary top up to the correct mark on the
dipstick or any other level indicator fitted (sight glass etc).
In addition where bearings are greased packed, the greases approved are NLGI grade 2 and recommended greases are
listed in the Approved Lubrication Scheme booklet available from David Brown.

Correct lubricant is most important and it should be noted that EP oils are essential in all instances. The nameplate of each
gear unit is stamped with the David Brown oil grade number which corresponds to the particular duty of the unit. The
table 11 gives details of suppliers and lubricants appropriate to the grade reference numbers from which a suitable
lubricant can be selected.
Lubricants listed are suitable for normal ambient temperatures and operating duties. All gear units in this range are
designed to operate under full load at a maximum temperature of 100ºC. Higher temperatures up to a maximum of 120ºC
are acceptable on the basis of peak periods of short duration only. In certain applications these maximum temperatures
may be exceeded by the use of special lubricants. Such cases or others where extreme conditions are to be met, e.g. low
temperature operation or unusual loading conditions, should be referred, with full details to David Brown for
recommendations.
The approved oils listed in table 11 are mineral lubricants. Mineral lubricants are not compatible with synthetic lubricants.

HOLLOW SHAFT WITH SHRINK DISC
Each shaft mounted gear unit is fitted with a ‘shrink disc’ device located on the hollow output shaft to provide a positive outer locking connection
between the gear unit the driven shaft. The ‘shrink disc’ is a friction device, without keys, which exerts an external clamping force on the hollow output
shaft, thus establishing a mechanical shrink fit between the gear unit hollow shaft and the driven shaft. ‘Shrink disc’ capacities have ample external
loading imposed on gear units.
Working Principle
The ‘shrink disc’ consists of two locking collars, a double tapered inner ring, locking screws and a sealing ring. By tightening the locking screws, the
locking collars are pulled together, exerting radial forces on the inner ring, thus creating a positive friction connection between the hollow output shaft
and the driven shaft.
As the tapered surfaces of the locking collars and the inner ring are lubricated with Molycote 321R or similar and the taper angle is not self locking,
locking collars will not seize on the inner ring and can be released easily when removal is necessary.
When the ‘shrink disc’ is clamped in position the high contact pressures between the tapered surfaces and the screw heads and their seatings ensure
hermetic sealing and eliminate the possibility of fretting corrosion.

COUPLING OPTIONS
Cone Ring
Accommodate all types of shaft misalignment met during normal operation, Being a development of the old pin and bush design
which it resembles in simplicity and ease of assembly and dismantling. Flexible cone ring couplings; types 611, 612, 613 and 614
are available in bore sizes up to and including 355 mm and has simplified torque rating up to 188,700Nm.
For the L series application the preferred coupling is the type 611, this is the heavy duty range with a parallel bore and can be
used as an input coupling between the L series gear unit and the prime mover or as an output coupling between the gear unit
and the application. It is a zero maintenance coupling, there are no re-greasing intervals or initial greasing requirements.
These couplings are manufactured locally at David Brown Gears Ind.
Grid Flex
A general purpose, lubricated design coupling that combines economy and high torque capacity of a gear coupling with the
flexibility of a cone ring coupling. The grid Flex couplings require non-periodic maintenance when lubricated with our long term
grease at installation. The Grid Flex coupling range has a basic torque rating of 932,000Nm and accommodates shaft diameters
up to and including 508mm.
For the L series application the preferred coupling is the Type T10, the coupling can be used as an input coupling between the L
series gear unit and the prime mover or as an output coupling between the gear unit and the application.
Couplings are supplied by David Brown, and can be sized for application by David Brown Application Engineers.
Gear type
A torsionally rigid coupling, lubricated design that offers high torque transmitting capacity. The gear couplings are designed to
AGMA size standards and feature triple-crowned teeth. 28 size gear couplings are available and can transmit over 8MNm with a
bore range up to and including 1025mm. The single engagement coupling can accommodate angular shaft misalignment and a
double engagement coupling can accommodate both angular and parallel shaft misalignment.
For the L series application the gear coupling is used on the output between the gear unit and the application, either a G20
(double engagement) or G52 (single engagement) can be used, depending on the system requirements.
Hydrodynamic coupling
A coupling based on Foettinger’s Principle, where either mineral oil or water is typically used as the operating fluid within the
coupling. The Hydrodynamic or fluid coupling allows for “soft-starting”, smooth acceleration and torque limitations from the
prime mover to the gear unit, the coupling can transmit in excess of 15.280Nm with a bore range of up to and including
180mm.
For the L series range the hydrodynamic coupling is used as an input coupling between the prime mover and gear unit. Most
often a coupling with a delay fill chamber is used, however the coupling design will vary depending on the applications
parameters and requirements. When two or more drives are driving an application the hydrodynamic coupling will allow for
effective load sharing between the two drives.
36
Rigid flange coupling
A coupling designed to replace conventional couplings which are normally keyed or heat shrunk onto the shafts. Shaft alignment
between the gear unit and application is eliminated as the two coupling halves are merely bolted together to create the rigid
coupling. The coupling is maintenance free and requires no initial greasing or lubrication. The rigid coupling can transmit
517,000 Nm with a bore range of up to and including 290mm. If a rigid coupling is used either the resilient bush type or swivel
type torque mounting must be used in conjunction to accommodate for reaction forces as the drive “hangs” from the
application shaft.
For the L series the rigid coupling is used on the output shaft between the gear unit and the application. There is no need for a
foundation to positively secure the drive to, only a reaction arm point is required for the torque mounting. If one drive needs to
be replaced by another drive it can be done simplistically and quickly.
Roller buffer coupling
A flexible coupling that incorporates rubber buffers to transmit the required torque. The rubber buffers shear when the
application is overloaded, thus protecting the system from damage. The roller buffer coupling can accommodate both parallel
and angular misalignment experienced during normal operation. The roller buffer coupling can accommodate up to 366,800 Nm
with a bore of up to and including 390mm.
For the L series gear unit the roller buffer coupling can be used as an input coupling between the prime mover and the L series
gear unit. Due to the torque rating and bore size range this coupling can also be used as an output coupling between the gear
unit and application.
*The above mentioned couplings are not the only couplings David Brown Gears recommends and supplies, they are however the
more common and popular couplings for L series range.
Resilient bush torque mount
A compact design torque mount with a resilient rubber bush and a steel stud. This design is compact and allow for both
compressive and tensile loading conditions that would be experienced in normal operation.
**To be used in conjunction with a rigid flange coupling
Swivel type torque mount
A versatile torque mount that is easy to install and allows for quite severs misalignment during operation. The overall length can
be varied from 350mm to well over 1500mm (load dependant). David Brown Engineers will determine the maximum loads and
lengths that the torque mount can accommodate.
**To be used in conjunction with a rigid flange coupling

IMPORTANT
Product Safety Information
General – The following information is important in ensuring safety. It must be brought to the attention of personnel involved in the selection of David Brown
Radicon (Pty) Limited power transmission equipment, those responsible for the design of the machinery in which it is to be incorporated and those involved in
its installation, use and maintenance.
David Brown power transmission equipment will operate safely provided it is selected, installed, used and maintained properly. As with any power transmission
equipment proper precautions must be taken as indicated in the following paragraphs, to ensure safety.
1. Fire/Explosion
a.
Oil mists and vapour are generated within gear units. It is therefore dangerous to use naked light in the proximity of gearbox openings,
due to the risk of fire or explosion.
b. In the event of fire or serious overheating (over 300°C), certain materials (rubber, plastics, etc) may decompose and produce fumes. Care
should be taken to avoid exposure to the fumes, and the remains of burned or overheated plastic/ rubber materials should be handled
with rubber gloves.
2. Guards- Rotating shafts and couplings must be guarded to eliminate the possibility of physical contact of entanglement of clothing. It should be of
rigid construction and firmly secured.
3. Noise- High speed gearboxes and gearbox driven machinery may produce noise levels which are damaging to the hearing with prolonged exposure.
Ear defenses should be provided in these circumstances.
4. Lifting- Where provided, only the lifting points or eyebolts should be used for lifting operations (see Maintenance and Installation manuals or general
arrangement drawings for lifting positions). Failure to use the lifting points provided may result in personal injury and/ or damage to the product or
surrounding equipment. Keep clear of the raised equipment.
5. Lubricants and Lubrication
a.
Prolonged contact with lubricants can be detrimental to the skin. The manufacturer’s instruction must be follows when handling
lubricants.
b. The lubrication status of the equipment must be checked before commissioning. Read and carry out all instruction on the lubricant plate
and in the installation and maintenance literature. Heed all warning tags. Failure to do so could result in mechanical damage and in
extreme cases risk of injury.
6. Electrical Equipment- Observe hazard warnings on electrical equipment and isolate power before working on the gearbox or associated equipment, in
order or prevent the machinery being started.
7. Installation, Maintenance and Storage
a.
In the event that the equipment is to be held in storage, for a period exceeding six (6) months, prior to installation or commuting, David
Brown Radicon (Pty) Limited must be consulted regarding special preservative requirements. Unless otherwise agreed, equipment must be
stored in a building protected for extremes of temperature and humidity to prevent deterioration.
b. External gearbox components may be supplied with preservative materials applied, in the form of a “waxed” tape overwrap pr wax film
preservative. Gloves should be worn when removing these materials. The former can be removed manually, the latter using white spirit as
a solvent.
c.
Installation must be performed in accordance with the manufacturer’s instructions and be undertaken by suitably qualified personnel.
d. Before working on a gearbox or associated equipment, ensure that the load has been removed from the system to eliminate the possibility
of any movement of the machinery and isolate power supply. Where necessary, provide mechanical means to ensure the machinery
cannot move or rotate. Ensure removal of such devices after work is complete.
e. Ensure the proper maintenance of gearboxes in operation. Use only the correct tools and David Brown Radicon (Pty) Limited approves
spares for repair and maintenance. Consult the Maintenance manual before dismantling or performing maintenance work.
8. Hot Surfaces and Lubricants
a.
During operation, gear units may become sufficiently hot to cause skin burns. Care must be taken to avoid accidental contact.
b. After extended running the lubricant in gear units and lubrication system may reach temperatures sufficient to cause burns. Allow
equipment to cool before servicing or performing adjustments.
9. Selection and Design
a.
Where gear units provide holdback facility, ensure that back-up systems are provided if failure of the holdback device would endanger
personnel or result in damage.
b. The driving and driven equipment must be correctly selected to ensure that the complete machinery installation will perform
satisfactorily, avoiding system critical speeds, system torsional vibration, etc.
c.
The equipment must not be operated in an environment or at speeds, powers, torques or with any external loads beyond those for which
it was designed.
d. As improvements in design are being made continually the contents of this catalogue are not to be regarded as binding in detail, and
drawings and capacities are subject to alterations without notice.
The above guidance is based on the current state of knowledge and our best assessment of the potential hazards in the operation of the gear units.
