Abstract

The invention relates to a two-stage worm gear and worm bevel wheel transmission speed reducer. The speed reducer adopts a two-stage transmission manner, a worm and gear is located on the high-speed stage, a bevel wheel is located on the low-speed stage, the two-stage worm and gear bevel wheel transmission speed reducer comprises a box body, an output shaft, a worm gear and a worm, the output shaft, the worm gear and the worm are mounted in the box body, a worm gear shaft is mounted in the middle of the worm gear, a spindle and the worm gear shaft are sleeved with gears and are connected, thegears are connected, and the worm is in a ZC tooth shape. Compared with the prior art, the transmission efficiency is improved, meanwhile, the need of outputting large torque is met, the whole bearingcapacity of the speed reducer is greatly improved, and the speed reducer can be mainly used for main drive of heavy escalators (public ladders).

Description

technical field [0001] The invention relates to a transmission device for decelerating and increasing torque in business or industry, and mainly relates to a two-stage worm gear helical gear transmission reducer. Background technique [0002] The reducer has a wide range of applications and can be seen everywhere in industry and daily life. There are many kinds of reducers, such as: ordinary spur gear reducer, worm gear reducer and cycloid reducer, etc., with different structures , with different properties. The main performance indicators of reducer products include transmission ratio, transmission efficiency, transmission torque, transmission stability performance and noise, etc. In different occasions and environments, different performance reducers can be selected according to needs. However, it is often difficult to choose a reducer with good comprehensive performance. The reducer currently on the market cannot meet such requirements and needs to be further perfected a...
