CALCULATION OF REQUIRED TORQUE:

The lifetime of gear reducer depends on calculation of required torque.Also please notice peak torque happened in accelerating or deceleratingshould be less then the maximum load torque of gear

Installation Suggestion of Planetary Gear Reducer

VGM

Suggestion instrument:

A Hex wrench which can measure torque.

Installation mothods

( )

Smear a little bit anti-corrosive oil on both output shaft and lead diameter.

If you have axle asleeve,pay attention to aim at the both plow grooves of

axle sleeve and the input shaft of the Gear Reducer.

Put the servomotor which you world like to install on the platform, and turn axle

center of output shaft upward. then, firm the servomotor and remove the kdy.

Please pay attention to make sure the plow groove of input shaft of the Gear

Reducer can aim at key groove of servomotor and then slowly lide plow prove

into key groove.

Lock the fixed screw of input shaft of the Gear Reducer

Lock both fixed screws of servomotor and gear Reducer tight.

Equally (dividing your force into three times)increase the torque grandually to

lock two sides of the fixed screws of input shaft of Gear Reducer.

Forbid knocking the output shaft of Gear Reducer with great force to prevent

damaging the interior mechanism of Gear Reducer.
