一般传动比较大的齿轮减速器,以前都采用蜗轮传动,但这种减速器效率低、耗铜量大。因此,我厂最近采用了一齿差行星齿轮减速器,它体积小、重量轻、零件数目少、效率高。图1为一齿差行星齿轮减速器装配图,当电机20带动偏心轴14转动时,由于内齿轮10与机壳固定不动,迫使行星齿轮11 General transmission gear reducer, used to have worm gear drive, but this reducer low efficiency, consumption of large copper. Therefore, I recently adopted a factory gear differential planetary gear reducer, which is small, light weight, small parts, high efficiency. Figure 1 is a gear differential planetary gear reducer assembly diagram, when the motor 20 drives the eccentric shaft 14 rotates, due to the fixed gear 10 and the housing, forcing the planetary gear 11
