Abstract

The invention relates to a composite speed reducer. The composite speed reducer comprises a worm transmission speed reducer and a small tooth difference planetary transmission speed reducer, wherein abox body of the worm transmission speed reducer is lockingly connected with a front supporting disc through a connecting disc; a supporting shaft is penetratingly connected between the front supporting disc and a rear supporting disc; the other end of a spline input shaft is penetratingly connected with the front supporting disc and the rear supporting disc through a bearing; a machine body is supported outside the front supporting disc and the rear supporting disc through bearings; an eccentric sleeve is in key connection with the portion, between the front supporting disc and the rear supporting disc, of the spline input shaft and is connected with two planetary gears in a penetrating mode through an eccentric bearing; the two planetary gears are connected between the front supporting disc and the rear supporting disc in a penetrating mode through an eccentric shaft and are engaged with an inner gear ring of the inner gear; an outer gear ring of the inner gear outputs; the inner gear is connected on the body in a penetrating mode through a bolt; and the rear supporting disc is connected with a supporting seat. The inner gear is driven by a worm, a worm wheel, the spline input shaft and the planetary gears to rotate, and output is achieved through the outer gear ring of the inner gear; and the composite speed reducer has the advantages of being compact in structure, large intransmission ratio, large in overload performance consumption, large in torque, good in overload bearing capacity, stable in operation, small in noise, long in service life and the like.

Description

technical field [0001] The invention relates to a speed reducer, in particular to a composite speed reducer. Background technique [0002] With the rapid development of my country's industrial technology, reducers are widely used in mechanical equipment in metallurgy, mining, chemical industry, construction, agriculture, transportation, power generation and other industries. The requirements for the reducer are getting higher and higher, generally including structure, transmission ratio, overload, torque, overload capacity, and performance requirements such as operation, noise, and life. The traditional single-drive structure reducer can no longer meet the increasing mechanical Equipment performance requirements. Contents of the invention [0003] The invention provides a compound speed reducer with compact structure, transmission ratio, overload, torque, bearing capacity and good performance. [0004] The technical solution adopted in the present invention is: a composi...
