Abstract

The motor-gear integrating transmission device consists of a driving part and a speed varying part. The speed varying part includes sun wheel, planetary gear, annular gear, planetary frame and output shaft. The driving part includes power supply leads, pole shoe, wire connector electrode, wire connector leading out shaft, winding and rotor. The winding is fixed inside the annular gear, the rotor has its front end screw connected to the output shaft and back end bearing supported onto the wire connector leading out shaft, and the wire connector leading out shaft has its front end screw fixed onto the sun wheel and back end bearing supported onto the casing. The power source is led to the winding via lead wires, pole shoe, wire connector electrode and wire connector leading out shaft. The transmission device has small amount of parts, high transmission efficiency and light weight.

Description

technical field [0001] The present invention relates to a transmission speed change device, more specifically, it relates to a planetary gear speed change device driven by a motor. It is suitable as a general-purpose power transmission device, and it can also be used as a special power transmission device in combination with several types of typical industrial machinery. It can also be used in automated machinery, common vehicles, military equipment, and places that urgently need to reduce the space of power transmission devices. occasion. Background technique [0002] The power transmission device is responsible for generating and transforming the power required by the output machine, and is a necessary component unit of all moving machinery, such as various machine tools, tools, vehicles, ... and so on. In terms of function, the power transmission device includes two parts: the power part and the speed change part. Among them, the role of the power part is to generate mo...
