Problems solved by technology

[0003] The reduction ratio of existing reduction boxes is determined by gear meshing transmission. Although the reduction box works reliably, when a large reduction ratio is required, the number of gear pairs is large, resulting in a large volume and weight of the reduction box. And the production cost is high, and the production takes more man-hours

Abstract

A speed reduction box with large transmission ratio belongs to the technical field of machinery. In order to realize the effects of reducing the volume and weight of the speed reduction box under the condition of the large transmission ratio, the speed reduction box comprises a speed reduction box body with a hollow structure, an output worm gear used for outputting torque, a rotating shaft arranged inside the speed reduction box body, a secondary worm arranged on the rotating shaft and matching with an output worm gear, a secondary worm gear and an input worm matching with the secondary worm gear, wherein one steel ball is respectively arranged at two ends of the rotating shaft; the steel balls come into contact with the internal walls of the speed reduction box body. The speed reduction box provided by the invention has the beneficial effects of small volume, light weight and low production cost.

Description

technical field [0001] The invention belongs to the technical field of machinery and relates to a speed reducer, in particular to a speed reduction box with a large transmission ratio. Background technique [0002] The reducer plays the role of matching the speed and transmitting torque between the prime mover and the working machine or the actuator. The reducer is a relatively precise machine. The purpose of using it is to reduce the speed and increase the torque. It can be divided into cylindrical gear reducer, bevel gear reducer and conical-cylindrical gear pulley reducer, which are widely used in modern machinery. [0003] The reduction ratio of existing reduction boxes is determined by gear meshing transmission. Although the reduction box works reliably, when a large reduction ratio is required, the number of gear pairs is large, resulting in a large volume and weight of the reduction box. And the production cost is high, and the production takes more man-hours. Cont...
