新型摩擦轮传动能作为增速器使用,也能作为减速器使用,甚至当成滚动轴承使用。一般行星齿轮传动一级速比限制在9:1以下,这是因其结构只允许在太阳轮和内齿圈之间安装一排行星齿轮。但是,新型行星摩擦轮传动,却可以安装一排或多排浮动的滚子,因而可获得大速比。当采用两排浮动行星滚子时,速比可达35:1;用三排时可达150:1;用四排时可达220:1。该传动的单位重量承载能力达11千瓦/公斤,而一般齿轮传动仅达6.5千瓦/公
The new friction wheel drive can be used as a gearbox, but also as a reducer, or even as a rolling bearing. The general planetary gear ratio is limited to a ratio of 9: 1, because its structure allows only one planetary gear to be mounted between the sun gear and the ring gear. However, the new planetary friction wheel drive, but can install one or more rows of floating roller, which can get a large speed ratio. When using two rows of floating planetary rollers, the speed ratio of up to 35: 1; with three rows up to 150: 1; with four rows of up to 220: 1. The transmission unit weight carrying capacity of 11 kW / kg, while the general gear transmission of only 6.5 kW /
