Boston gearheads provide
precise, durable and
long-lasting performance
The Boston Gear line of servo gearheads has been
designed for direct attachment to popular servomotors.
Power is transmitted from the motor to a sun gear
which drives three planet gears contained within an
internal toothed ring gear. The planet gears are
mounted in a carrier with double wall supports. The
output shaft automatically rotates as the planet gears
and carrier rotate.

PR2 Series
Due to the load sharing attributes of multiple tooth
contacts, planetary gearboxes provide the highest
torque and stiffness for any given envelope. Balanced
planetary kinematics at high speeds combined with the
associated load sharing make planetary-type gearheads
ideal for servo applications. Other significant
advantages include:

• True helical technology provides increased tooth to
tooth contact ratio by 33% vs spur gearing
- 12º helix angle produces smooth and quiet
operation
• One piece planet carrier and output shaft design
reduces backlash
- Single step machining process
- Assures 100% concentricity

Many applications typically associated with conventional power
transmission solutions are beginning to utilize servo control and precision
gearheads to meet production requirements. Servo-driven solutions can
achieve faster speeds with more precise accuracy while providing greater
flexibility and quicker changeover.
1
Boston gearheads... the most robust gearheads available.
Superior engineering and design combined with the lastest technology have resulted in the creation of a full
line of gearheads loaded with enhanced features. Patented planet carrier design, patented input and output
sealing designs and special heat and surface treatments are just a few of the unique features that give
Boston gearheads a competitive edge.

Patented output sealing systems design
7
eliminates friction and heat generation
which is accomplished by applying a
hi-tech Titanium Carbon Nitride coating
to all output contact surfaces. The TiCN
coating reaches a hardness of 3000Hv
and is ground to Ra 0.2µm finish to
ensure sealing.
1
Equipped with solid uncaged
needle roller bearings, provides
maximum contact points
to increase stiffness and
generates high
output torque.
8
A high setting gear performance is
achieved by using advanced gearing
technology, by easing off the tooth profile
and crowning the lead of each tooth.
This optimizes the gear mesh
alignment and overlap to achieve
maximum tooth surface contact.
Patented planet carrier design places the sun
gear bearing directly into the planet
carrier. This ingenious concept eliminates
gear misalignment and gains the highest
accuracy on the market. Less than 1
arc-minute backlash!

9
A special non-electrolysis nickle surface
treatment on the output housing and
black anodized aluminum input adapter
are provided for the most extreme
environmental conditions to achieve
an IP65 Rating.
3
Single piece planet carrier with an
extended, tapered roller bearing
provides maximum radial load
capacity (up to 50,000 NM)
and increases system
reliability and stiffness.
10
4
Plasma nitriding heat treatment process
maintains the tooth surface hardness
at 840Hv for superior wear-resistance
and a core hardness at 30HRc
for toughness.
True Helical Gear Design
Precision helical gearing increases
tooth to tooth contact ratio by over
33% versus spur gearing. The helix
angle produces smooth and quiet
operation with decreased backlash
(less than 1 arc-minute and less
than or equal to 56dB).
Solid, single-piece sun gear
construction obtains precise
concentricity with increased
strength and rigidity.
11
The unique motor adapter and bushing
module system design allows for quick
and easy mounting of
any motor.
5
12
Triple split collet with dynamic balanced set
collar clamping system provides backlash
free power transmission and eliminates
slippage. 100% concentricity allows for
smooth rotation and higher input speed
capability.
6
Precision tapered roller bearing
support to increase radial and
axial loading capacity.
13
Patented input sealing system design
eliminates breakaway torque and decreases
friction/heat. The TiCN coated bushings
(1700 Hv, Ra 0.2µm finish) interface with a
proprietory seal which decreases wear and
erosion of both sealing surfaces. This new
design prevents leakage and has a service
life of over 30,000 hours.

PL2 Series
Radial and axial loads allowed on the output shaft
L
X
The permitted radial and axial loads on the output
shaft of the gearbox is dependent upon the design
of the gearbox supporting bearings. The Boston
Gear PL2 Series uses an oversized, straddle
mount, ball bearing design, which can take heavy
loads from both axes.
F2r
F2a2 F2a1
F2r Radial Load
F2a Axial Load
If the radial force F2r is exerted on the center of
the output shaft, then X=0.5 x L.
PL2220
Under these conditions the permitted radial load
can be determined from the graph on the left.
PL2180
The permitted axial load can then be calculated
by using the following formulas:
PL2142
PL2115
F2a1B = 0.2 x F2rB (axial force towards the gearhead)
PL2090
PL2060
F2a2B = 0.1 x F2rB (axial force away from the
gearhead)

If the radial force F2r is not exerted on the
center of the output shaft then X is the
distance measured from the output seal.
The position load factor Kb can then be
determined by the graph to the left.
Under these conditions the radial and axial
loads can be calculated by using the following
formulas:
Radial Load:
F’2rB=Kb x F2rB
Axial Load:
F’2a1B=0.2 x F’2rB
* Continuous running reduces service life by 50%.

L
shaft of the gearbox is dependent upon the design of
the gearbox supporting bearings. The oversized,
tapered roller bearing, straddle mount design for the
PL6 Series accomodates high radial and axial loads
with extended life. This design enables a 50% more
load capacity than a standard angular contact
bearing design.

shaft of the gearbox is dependent upon the design of
the gearbox supporting bearings. The oversized,
tapered roller bearing, straddle mount design for the
PR6 Series accomodates high radial and axial loads
with extended life. This design enables a 50% more
load capacity than a standard angular contact
bearing design.

If the radial force F2r is not exerted on the center
of the output shaft, then X is the distance
measured from the output seal.
Under these conditions the radial and axial loads
can be calculated by using the following formulas:
Radial Load:
F’2rB=Kb x F2rB
Axial Load:
F’2a1B=0.2 x F’2rB
F’2a2B=0.1 x F’2rB

Motor Mounting Instructions
1.
Double-check the motor and gearbox size.
Clean the mounting surface.
5.
Attach the motor. Tighten to 5% of the
recommended torque shown in Table 2.
2.
Remove the plug on the adapter plate.
Rotate the set collar until the bolt is aligned with the hole.
6.
Tighten the mounting bolt (including washer) in 1~4 order
with torque wrench to specified torque. (See Table 1)
3.
Remove motor key.
7.
Tighten the set collar bolt with torque wrench to
specified torque. (See Table 2)
4.
Check motor shaft size and insert bushing if necessary.
8.
Tighten back the screw plug.
When installing on flatted
shafts, be sure to align
the collet gap over the
flat and the set collar bolt
perpendicular to the flat.
