INTRODUCTION

When compared to the single-stage planetary gearbox. The 3 – stage planetary gearbox has many advantages. thus despite its greater production needs and higher cost. a big number of people will prefer to utilize such a reduction device. In fact, in the current use of equipment. some high standard machinery is the need for such a gearbox to complete production tasks.

Planetary gearboxes have more reduction ratio. more output torque, a wider range of deceleration, gear box return clearance accuracy. and other advantages over two planetary gearboxes. they also have a small size, light weight, smooth operation. low noise, and performance safety features. It also has the properties of power shunt and multi-tooth meshing.
