General Design Features
Hub City parallel shaft speed reducers provide you with a
nearly unlimited degree of design flexibility in OEM
configurations, or for incorporation in existing systems. Up
to three input modes provide for integration with hydraulic
motors, electric motors, or for externally coupled driving
sources.
Units can be specified for torque to 122,361 lb.-in., horsepower
ratings to 530 H.P., and reduction ratios to 70:1, depending on
the model and AGMA class of operation required. The wide
range of ratios is facilitated by the availability of single and
double reduction designs.
Hub City parallel-shaft speed reducers provide the advantages
of a sealed, integrated configuration —compact and easily
planned into your systems with inherently accurate shaft
alignment. A wide range of ratios and ratings offer a selection
which can usually be utilized with the driven equipment. These
capabilities can also be extended where necessary by use of
external V-belts, chains, and other couplings.
All units are designed for long service under heavy-duty
conditions, and machined from high alloy gray iron or ductile
iron housing castings. The gear drives are equipped with ball,
roller or tapered roller bearings, depending on position in the
gear train and on operating requirements. Units also include
high strength high alloy case hardened gears, double lip seals,
and high quality steel shafts and sleeves.
Hub City provides adaptors for most units for both hydraulic
and NEMA C Face electric motors, as well as all required
bushings, backstops, torque arms, and other accessories that
may be required for most applications. Consult each individual
reducer dimension page for input styles available.
This catalog includes representative standard Hub City
shaft-mounted speed reducers; however, complete
engineering capabilities are available to you for development
of modified or new designs.
Input Configuration Descriptions
Shaft Input Units – These speed reducers are designed for
external coupling through V-belts, chain drives,
or other means. Overhung load data can be
provided on individual models.
Pre-Selection Information
Electric Motor Units – Hub City speed reducers in this group
are equipped with a NEMA “C” flange for
direct mounting to a flanged electric motor.
The electric motor shaft and reducer input
pinion mate coaxially.
Backstops
Optional backstops are offered at extra cost for applications
that require the prevention of reverse rotation. Backstops are
built-in to the high speed shaft module assembly. Backstops
must be factory assembled. When ordering specify desired
direction of free rotation of the reducer output shaft – as
viewed facing the end of the shaft extension.
Backstops are not recommended for applications
involving energy absorption and shock or torque loads in
excess of reducer ratings or on applications such as chair lifts,
amusement rides, etc. where the safety of a person or property
is dependent on their function. On such applications, other
safety devices should be provided.
Backstops are designed to prevent rotation not more than
five times in an 8 hour period with a minimum of one minute
in the over-running direction between each engagement. If
reversing operation is more frequent or over-running time is
less, the application should be referred to the factory.
NOTE: Lubricants with extreme pressure (EP) additives
should not be used in units with built-in backstop.
F
EFFICIENCY
Helical or Spur Gearing and Ball or Tapered Roller Bearings
provide a drive with very high efficiency. The approximate
efficiency is 97.5% per gear stage.
How To Order
When ordering a Parallel Shaft Drive it is necessary to select
a model, gear ratio, input configuration and assembly style
where applicable.
For shaft mounted units also specify output bore size.
Hydraulic Motor Units – These speed reducers are provided
with either a 2-bolt or 4-bolt mounting flange
for direct coupling to a hydraulic motor.
The hydraulic motor shaft mates directly
with the reducer input pinion through a
spline or round key adaptor. A “floating”
adaptor accommodates any possible
concentricity difference.
Input configuration options:
Shaft
Hydraulic (specify flange size and input bushing size)
Electric(specify flange size and input bushing size)
(see above for Input Configuration Descriptions)
Not all input configurations are available on all models.
See individual model pages for input configurations available.

Quick Model Selection
Hub City Parallel Shaft Speed Reducers can be selected on the basis
of speed and torque or horsepower. Quick selection tables on the
following pages can be used with 1750 rpm input speed and uniform
power source. Table 3 provides reducer selection by H.P. and output
speed. It also provides different AGMA load classifications designated
for shaft mount reducers. Tables 4 and 5 provide selection by output
torque and output speed, for Class I service (1.00 S.F.). Conversion
factors for AGMA class II and III are provided below the tables.
For other input speeds, and specific rating data, refer to the unit rating
tables for each model.
TABLE 1 — SERVICE FACTORS
SERVICE FACTORS
The ratings for gear drives in this manual are based on a service
factor of 1.00, for uniform load and uniform power source, up to
10 hours of operation per day. For other operating conditions, the
application horsepower or torque must be multiplied by the
appropriate service factor, to determine the equivalent gear drive
power rating. A gear drive should be selected with a rated capacity
equal to or greater than the equivalent rating.
AGMA Load Classification Numbers for Gearmotors and Shaft Mount
Reducers are listed on pages A-5 and A-6. AGMA Load Classification
Numbers for Drives and Reducers are listed on pages A-7 and A-8.
