Cycloid reducer introduction

high speed planetary gearboxes is a kind of application of planetary transmission principle, the use of cycloid gear meshing of the new transmission device.
Cycloid reducer All gears can be divided into three parts: the input part, the deceleration part, the output part. In the input shaft is equipped with a dislocation 180 ° double eccentric sleeve, eccentric sleeve with two known as the arm of the roller bearing, the formation of H institutions, the two cycloid center hole is eccentric sleeve arm And the Sugar mill gearbox is engaged with a set of annularly arranged needles on the pinion gear to form an internal gear reduction mechanism having a tooth difference as a tooth (in order to reduce the friction, in the case of a small speed ratio , Needle teeth with needle sets).
When the input shaft with a set of eccentric rotation, due to the characteristics of the cycloid on the profile curve and the needle on the needle on the needle so that the movement of the cycloid has become both open and rotating plane movement, in the When the input shaft is rotated forward, the eccentric sleeve is also rotated for one week, the cycloid turns in a tooth in the opposite direction to obtain the deceleration, and then through the W output mechanism, the low speed rotation of the cycloidal wheel is transmitted to the output shaft through the pin, Resulting in a lower output speed.
