Planetary gear stepper motor

Basic Info

Model No.: 9N.m-30N.m

Product Description

All transmission devices can be divided into three parts: the input part, the deceleration part and the output part.Dislocation on the input shaft is equipped with a 180 ° of the double eccentric sleeve, turn on the eccentric sleeve is equipped with two called arm of Roller Bearing, the formation of H, two cycloid gear center hole is the eccentric sleeve on the turning arm bearing raceway, and by a group of cycloid gear and pin gear mesh circular permutation needle Brushless dc motors, to form tooth differenceStero servomotors, for the internal meshing gear reducer is institutions (in order to reduce friction, in small ratio of speed reducer, the needle with needle teeth on the gear set).When the input shaft rotates once with an eccentric sleeve, due to the characteristics of the tooth profile on the cycloid wheel and the restriction of the needle teeth on the needle gear Planetary Gear Stepping Motor 56JPS300K/STS57HD Linear motor, the cycloid wheel's motion becomes a plane motion with both revolution and rotation. When the input shaft turns around positively
