Design on Built-in Driving Drum Based on Closed Differential Planetary Gear

In order to solve the problems of large axial size, large noise and heavy weight of the external driving drum, a new built-in driving drum is designed. Taking closed differential planetary gear as the driving device, this driving drum makes the motor placed outside the driving drum and lets them connected by a bevel gear. Three-dimensional software SolidWorks is used to draw the driving drum parts and Three-dimensional assembly drawings.
