Precise hollow shaft 2K-V type reducer

中空轴精密2k-v型减速机

Abstract

The utility model discloses a precise hollow shaft 2K-V type reducer. The reducer comprises a crankshaft, a cycloidal gear, a pin wheel housing, an output disc, a rigid disc, a synchronizing wheel and an input gear shaft, wherein the input gear shaft is a hollow shaft and is meshed with the synchronizing wheel to transfer power and motion to the reducer; the transfer and output of the power and motion are completed by the crankshaft, the cycloidal gear, the pin wheel housing and a planet carrier; the reducer is generally used for a transmission joint of an industrial robot; the transmission structure of the reducer is not a general series-parallel connection structure, but is a novel transmission structure which is formed by compounding a first stage involute planetary transmission with a second stage cycloidal-pin wheel transmission; the precise hollow shaft 2K-V type reducer has the advantages that the size is small, the structure is compact, the weight is light, the transmission ratio variation range is large, the efficiency is high, the precision is high, the rigidity is high, the service life is long, and the like.
本实用新型为一种中空轴精密2K-V型减速机,本减速机包括曲柄轴、摆线轮、针齿壳、输出盘、刚性盘、同步轮、输入齿轮轴,所述输入齿轮轴为中空轴,与同步轮啮合向减速机传递动力和运动,通过曲柄轴、摆线轮、针齿壳、行星架完成动力和运动的传递和输出,这种减速机一般用于工业机器人的传动关节;这种减速机的传动结构不是一般的串并联结构,而是一种由第一级渐开线行星传动和第二级摆线针轮传动复合而成的一种新型传动结构,其具有体积小、结构紧凑、重量轻、传动比变化范围大、高效率、高精度、高刚度、使用寿命长等优点。
