on performance and mechanism
该减速机在传动上由一级螺旋伞齿轮和一级行星齿轮传动组成,与同样额定功率和传动比的三级普通螺伞—圆柱齿轮减速机相比,不仅体积小、重量轻,而且传动平稳、噪音低、效率高等。所有这些主要是由于利用了行星齿轮传动的特点,同时又由于磨齿加工齿轮的数量占齿轮总数量的百分比提高,使得整个传动的各种性能大大提高所致。 The gear reducer posed of one-stage spiral bevel gear and one-stage ary gear in terms of drive. Compared with three-mon spiral bevel gear—cylindrical gear reducer, the gear reducer proper is featured by small volume, light weight, stable driving, low noise and high efficiency, etc. All these features are attributed to the utilization of ary gear drive and increased ratio of no. of grinding t
