可换电动机的机械臂关节

Robotic Arm Joint with Interchangeable Motor

为了让机械臂具有多种控制方式,方便人们使用机械臂关节时可以在速度与精度中切换,提出了可换电动机的机械臂关节。该设计采用了左轮手枪的原理,打开外壳的一部分外壁使电动机显露出来,用拧螺丝的方式进行电动机更换,通过电动机上的齿轮与减速器轴上的齿轮进行传动。减速器采用了行星轮减速,由1个太阳轮和3个行星轮组成,减少了晃动所带来的误差,也解决了不同电动机的替换所带来的不同稳定性。

In order to allow the robotic arm to have multiple control methods,so that people can switch between speed and accuracy when using the robotic arm joint,a robotic arm joint with interchangeable motors is proposed.The design uses the principle of a revolver,opening a part of the outer wall of the casing to expose the motor,replacing the motor with a twisted screw,and transmitting by the gear on the motor and the gear on the reducer shaft.The reducer uses planetary gear reduction,consisting of 1 sun gear and 3 planet gears,which reduces the error caused by shaking and also solves the different stability brought by the replacement of different motors.
