HYBRID
How to choose the type of gearhead depends primarily on the application. Some of the factors to be considered to make proper trade-offs between cost and performance are shown below. The hybrid design of planetary and spur gears are not offered by us but are available on the market, and are included for comparison purposes.

PLANETARY GEAR SYSTEM

Planetary Gear System
The basic form of planetary gear system is shown above. It consists of a sun gear A, planetary gears B, internal gear C and carrier D. In our gearheads the internal gear is fixed, the sun gear is the input pinion, and the output shaft is part of the carrier.
This relationship can be represented schematicallyas shown on the right. The speed ratio is given by the equation:
za 1+ –– zc za + zc zcGear Ratio = –––––– = –––––– = –– + 1 za za za –– zc
where: za = number of teeth in sun gear A, and zc = number of teeth in internal gear C.
A
BC (Fixed)
D
For the example shown in the above illustration (where za = 14, zb = 18 and zc = 50), the Gear Ratio is 4.6:1.
For a double-stage planetary gearhead, the carrier of the first stage becomes the sun gear of the second stage.
The advantages of the planetary gearheads are: 1. The input and output axes are in the same line. 2. The planet gears used in a planetary system share the
load, allowing for a much higher torque capacity unit than the comparable size spur gearheads.
3. The unit is compact and inertially balanced.
The disadvantages are: 1. The mechanism is complex. 2. The components require high-precision manufacturing. 3. The cost is considerably more than comparable size spur
gearheads.
USEFUL FORMULAS

The maximum allowable The maximum output HP of gearhead output HP of the motor 0.90 (single stage) or 0.85 (double stage)
Effective inertia load inertia gearhead∆ pinion∆ (gear ratio)2 inertia inertia For very fast response, the effective inertia should be one to three times larger than the motor inertia (including the pinion).
For acceptably fast response, the effective inertia should be less than ten times larger than the motor inertia (including the pinion).
∆ Inertia values shown in this catalog include both the gearhead and pinion values.

T-SERIES GEARHEAD MOUNTING INSTRUCTION
GEARHEAD RATIO UNIT with BUILT-IN PINION
MOUNTING BRACKET
MOTOR SHAFT SLEEVE
MOTOR
All of our NEMA and Metric sized gearheads, except NEMA size 17, are offered using a ready-to-mount system of attaching the motor to the gearhead. The gearhead ratio unit includes a preinstalled pinion and a self-aligning input clamp. This allows the gearhead to maintain concentricity with the motor shaft and eliminates the need to set the pinion.
The procedure for selecting a complete gearhead solution is simple:
Step 1. Select you motor and determine the appropriate frame size for the gearhead.Step 2. Measure the pilot diameter E, pilot length (from motor), bolt circle, shaft OD and shaft length of your motor.Step 3. Based on your measurements and frame size selection, go to the page that lists the mounting bracket and sleeve that you require.Step 4. Choose the reduction ratio and complete the part number.
Example: You have a size 60 motor and you measure the pilot diameter to be 50.4 mm, the pilot length to be 3.8 mm, the bolt circle to be 67 mm, the shaft diameter to be 10 mm and the shaft length to be 30 mm. If your required reduction is 30:1 then you woud select mounting bracket "1" and sleeve "G". Therefore the part number you would need to order is: S9160TM0301G
NOTE: The mounting brackets and motor shaft sleeves listed in this catalog complement 90% of the motors currently available. If your motor does not meet our gearhead specifications, please contact our engineering staff to arrange for a custom mounting bracket or motor shaft sleeve.

GEARHEAD TO MOTOR MOUNTING INFORMATION
MOUNTING INSTRUCTIONS:
A) Using the screws provided, bolt the mounting bracket to the input end of the gearhead ratio unit.
B) Slide the motor shaft sleeve into the input clamp and align the slot in the sleeve with the slot in the clamp.
C) Rotate the clamp to align the mounting bracket access holes with the clamping bolts.
D) Place the motor on a solid work surface with the output shaft pointing up. Slide the assembled gearhead onto the motor shaft.
E) Using a torque wrench, tighten the clamp bolts to the pretightening torque values listed below.
F) Using the screws provided, bolt the gearhead to the motor.
G) Using an alternating pattern, gradually tighten the clamp bolts until you reach the final tightening torque listed below.
