少齿差行星齿轮减速器是属“K-H-V”传动,其传动原理和摆线针轮减速器一样,所不同的是用渐开线啮合代替摆线针齿啮合。少齿差行星齿轮减速器的特点是速比大,结构紧凑,重量轻,体积小,效率也较高一般η=0.8—0.9。由于采用内啮合和较大的变位,因而提高了齿的表面接触强度和弯曲强度。进、出轴 Less tooth difference planetary gear reducer is a “K-H-V” drive, the transmission principle and cycloid reducer, the difference is the use of involute mesh instead of cycloidal pin gear meshing. Less tooth difference Planetary gear reducer is characterized by large speed, compact structure, light weight, small size, high efficiency and general η = 0.8-0.9. As a result of the internal engagement and greater displacement, thereby increasing the tooth surface contact strength and bending strength. In and out of the shaft
