Stages and applications of cylindrical gear reducers

Cylindrical reducers can be divided into single-stage, two-stage, three-stage and multi-stage reducers according to the number of reduction gears; according to the mutual configuration of axes in space, it can be divided into vertical and horizontal reducers; according to the characteristics of motion diagrams, It can be divided into expandable, coaxial and splitter.The maximum transmission ratio of a single-stage cylindrical gear reducer is usually 8-10.This restriction is mainly to avoid excessive overall dimensionality.If 10 is required, a two-stage cylindrical reducer should be used.
When I: 8-50 and the center distance of the high-speed stage and the center distance of the high-speed stage are 250-400mm, a two-stage cylindrical gear reducer should be used.The three-stage cylindrical reducer shown in the figure is used in occasions requiring large transmission.Bevel gear reducer and two-stage bevel cylindrical gear reducer, with
The utility model is applicable to the speed changer that output input shaft and output shaft 90～arrangement.Because large-sized bevel gears are difficult to manufacture accurately, the high-speed stage of the bevel cylindrical gear reducer is always driven by bevel gears to reduce its size and improve manufacturing accuracy.The gear reducer is characterized by high efficiency, long service life and simple maintenance, so it is widely used.
