6 VGM How to Selet a Gear Reducer Choose an applicable reduction radio. Raduction radio RPM servomotor RPM gear reducer output CALCULATION OF REQUIRED TORQUE: The lifetime of gear reducer depends on calculation of required torque. Also please notice peak torque happened in accelerating or decelerating should be less then the maximum load torque of gear CALCULATING FORMULA FOR REPERENCE: TP=(GD L +GD a +GD M) N/375 T L )/R TP: 2 GD M: 2 GD L : 2 GD a : R: TL: t: N: +: -: Min. torque required at moment of starting, that gear reducer should bear against peak touque at moment.

7 VGM Installation Suggestion of Planetary Gear Reducer Suggestion instrument: Installation mothods A Hex wrench which can measure torque. 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. The Flange Facing to Input Shaft at the Back-End of Gear Reducer Reducer. The Fixed Screw Holes of Servomotor and Gear Reducer The Fixed Screw of Input Shaft Input Shaft
