Roller worm speed reducer

Abstract

The invention discloses a roller worm speed reducer. A machine shell, first worms, a first rotation disc, a second worm and second rotation discs are included. The first worms are symmetrically arranged on the two sides in the machine shell relative to the center axis of the machine shell. The first rotation disc is in meshing connection between the two first worms. The ends, close to a first cover plate, of the two first worms are coaxially connected with the second rotation discs. The second worm is in meshing connection between the two second rotation discs and is perpendicular to the planewhere the first rotation disc is located. The double worms are utilized for simultaneously pushing following devices on respective sides correspondingly, and transmission strength and rigidity are greatly improved; the structure is compact and reasonable, and the size is reduced; and meanwhile, two-level speed changing is utilized for power transmission, the number of rollers is reduced, the wormabrasion probability is reduced, the service life is prolonged, and the back clearance precision retentivity of the speed reducer is increased in a multiplied manner.

Description

Technical field [0001] The invention relates to the field of reducers, in particular to a roller worm reducer. Background technique [0002] A worm gear reducer is a power transmission mechanism that uses a gear speed converter to reduce the number of revolutions of a motor (motor) to the required number of revolutions and obtain a larger torque. In the mechanism used to transmit power and motion, the application range of the reducer is quite wide, and its traces can be seen in the transmission system of all kinds of machinery. Reducer has the function of reducing speed and increasing torque, so it is widely used in speed and torque conversion equipment. The roller worm reducer actually uses the working principle of the worm gear reducer to replace the worm gear of the worm wheel with a follower. The reduction ratio is the ratio of the number of worm teeth (commonly known as the number of heads) to the number of followers on the turntable. The transmission structure is: a worm,...
