自动洗衣机行星齿轮减速器设计

Design of Planetary Gear Reducer for Automatic Washing Machine

本课题是关于自动洗衣机减速离合器内部减速装置行星齿轮减速器的设计。在洗衣机中使用行星齿轮减速器是利用了行星齿轮传动体积小,质量小,结构紧凑,承载能力大;传动效率高;传动相比大等特点。另一方面,巧妙利用行星齿轮减速器的结构特点,控制内齿圈来实现洗涤和脱水两个动作。本次设计的减速器与现有减速器相比,除了考虑减速器载荷、体积以及传动比等要求以外,更多考虑减速器的使用寿命,和可靠性,加入了均载机构和卸荷结构,减少了因为载荷的不均匀和带轮径向力带来的负面影响。

This topic is about design method for the planetary gear reducer which is the internal reduction gear of the reducing gear clutch for automatic washing machine.The planetary gear reducer is used in the washing machine because it has advantages of small volume,small quality,compact structure,large carrying capacity,high transmission efficiency,etc.On the other hand,washing and dehydration could be realized by controlling the annular gear based on the structural characteristics of planetary gear reducer.Compared with the existing reducer,in addition to requirements of the gear load,size and transmission ratio,the gear reducer designed in this article is much better on the asspects of service life and reliability,and it adds the load balancing mechanism and the unloading structure so as to reduce the negative effects caused by the uneven load and pulley of radial force.
