Novel double-input-arc bevel gear reduction gearbox

Abstract

The invention provides a novel double-input-arc bevel gear reduction gearbox. The novel double-input-arc bevel gear reduction gearbox comprises a hand wheel shaft, a box body, an upper bearing, a leftbearing, a right bearing, a long shaft, a large bevel gear and a small bevel gear; an upper end cover, a left end cover and a right end cover are arranged at the openings of an upper end surface, a left end surface and a right end surface of the box body respectively; an outer ring of the upper bearing is fixed on the upper end cover, the hand wheel shaft penetrates through the upper end cover, the upper bearing extends into an inner cavity of the box body, the hand wheel shaft is in interference fit with an inner ring of the upper bearing, the small bevel gear is fixedly connected with the lower end of the hand wheel shaft, an outer ring of the left bearing is fixed on the left end cover, an outer ring of the right bearing is fixed on the right end cover, the long shaft penetrates through the right end cover and is connected with inner rings of the left bearing and the right bearing in an interference fit manner, and the large bevel gear is fixedly connected with the long shaft and is meshed with the small bevel gear.

Description

technical field [0001] The invention relates to a reducer technology, in particular to a novel double-input spiral bevel gear reducer. Background technique [0002] As a kind of precision machinery, the reducer has the function of low speed and increased transmission torque in the transmission system, and it is more and more widely used in modern machinery. According to the size of the transmission stages, it can be divided into two types, single machine and multi-stage reducer; according to the gear type in the reducer, it can be divided into involute gear and arc gear; according to the layout of the transmission, it can also be divided into shunt type and expansion. There are two types of reducers, open and closed. [0003] The advantages of simple structure and convenient loading of bevel gear transmission reducer make it widely used in aerospace agencies, precision instruments and servo transmission systems. At present, most bevel gear reducers on the market have only...
