A Gear Reducer with Accurate and Reliable Reduction Ratio

Abstract

The invention discloses a gear reducer with accurate and reliable reduction ratio, comprising a housing, an inner toothed disc, planetary gears, the intervals of which are arranged in the inner toothed disc, and a cylinder between the center of the gear column and the first end of the gear column. There is a sun gear set; at least two follower gear sets are symmetrically arranged on the outer circumference of the sun gear set, the radial position of the follower gear set is fixed on the inner toothed disc, and the follower wheel set moves axially synchronously with the gear column ;The grading gear set is set on the outer circumference of the follower gear set, and the grading gear set moves axially synchronously with the gear column; the inner wall of each grading gear is provided with an inner ring gear, and the innermost end of the follower gear is connected to the corresponding sun gear The outermost sidewall of each stepping gear meshes with the innermost sidewall of the planet gear, the outermost end of the follower gear meshes with the inner ring gear of the corresponding stepping gear, and the outermost sidewall of each stepping gear and the innermost sidewall of the planetary gear axially selectively mesh. The invention solves the technical problem of unreliable accuracy of the output reduction ratio of the reducer in the prior art.

Description

technical field [0001] The invention relates to the technical field of reducers, more specifically, the invention relates to a gear reducer with accurate and reliable reduction ratio. Background technique [0002] The reducer is generally used for low-speed and high-torque transmission equipment. The motor, internal combustion engine or other high-speed running power is used to achieve the purpose of deceleration through the gear with a small number of teeth on the input shaft of the reducer and the large gear on the output shaft. Ordinary The reducer will also have several pairs of gears with the same principle to achieve the ideal deceleration effect. The reducer is a mechanical transmission device in many fields of the national economy. The product categories involved in the industry include various gear reducers, planetary gear reducers and worm reducers. It also includes various special-purpose transmission devices, such as speed-increasing devices, speed-regulating dev...

Problems solved by technology

[0003] At present, in order to enrich the reduction ratio of the reducer and provide more selectivity, a stepless reducer has appeared in the prior art, and the reduction ratio is continuously adjustable, but the output reliability of the stepless reducer is poor and cannot provide accurate Reliable reduction ratios leading to setbacks in industrial applications
