PL2 Series
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

PR2 Series
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. Due to the load sharing attributes of multiple tooth contacts, planetary gearboxes provide the highest torque and stiffness for any given envelope. Balanced

PL6 Series
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

Equipped with solid uncaged needle roller bearings, provides maximum contact points to increase stiffness and generates high output torque.
8 Patented planet carrier design places the sun
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.
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!

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.

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.

The unique motor adapter and bushing module system design allows for quick and easy mounting of any motor.

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 0.2Îźm 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

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 PL2090 PL2060
F2a1B = 0.2 x F2rB (axial force towards the gearhead) F2a2B = 0.1 x F2rB (axial force away from the gearhead)
PL2042
PL2042 PL2060 PL2090 PL2115 PL2142 PL2180 PL2220
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%.

PR2 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 PR2 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. PR2220
PR2180 PR2142 PR2115 PR2090 PR2060
Under these conditions the permitted radial load can be determined from the graph on the left. The permitted axial load can then be calculated by using the following formulas: F2a1B = 0.2 x F2rB (axial force towards the gearhead) F2a2B = 0.1 x F2rB (axial force away from the gearhead)

PR2042 PR2060 PR2090 PR2115 PR2142 PR2180 PR2220
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%.

PL6 Series Radial and axial loads allowed on the output shaft L The permitted radial and axial loads on the output 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.

If the radial force F2r is exerted on the center of the output shaft, then X=0.5 x L. PL6220 PL6180 PL6140
Under these conditions the permitted radial load can be determined from the graph on the left.
PL6100
The permitted axial load can then be calculated by using the following formulas:
PL6075
F2a1B = 0.2 x F2rB (axial force towards the gearhead)
PL6060
F2a2B = 0.1 x F2rB (axial force away from the gearhead)
PL6042
PL6042 PL6060
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.
PL6075
The position load factor Kb can then be determined by the graph to the left.
PL6100 PL6140
Under these conditions the radial and axial loads can be calculated by using the following formulas:
PL6180 PL6220
Radial Load: F’2rB=Kb x F2rB Axial Load: F’2a1B=0.2 x F’2rB F’2a2B=0.1 x F’2rB

If the radial force F2r is exerted on the center of the output shaft, then X=0.5 x L. Under these conditions the permitted radial load can be determined from the graph on the left. PL5205 PL5235 PL5155 PL5120 PL5090 PL5070
The permitted axial load can then be calculated by using the following formulas: F2a1B = 0.2 x F2rB (axial force towards the gearhead) 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 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 on page 35.
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 on page 35)
3.
Remove motor key.
7.
Tighten the set collar bolt with torque wrench to specified torque. (See Table 2 on page 35)
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.
