Improved swing disc reducer

Abstract

The invention provides an improved swing disc reducer, and belongs to the technical field of reducers. The improved swing disc reducer comprises a shell body, an input shaft and an output shaft. The improved swing disc reducer further comprises an input mechanism, a reducing mechanism and an output mechanism. The reducing mechanism further comprises first inner roller pins, a first tooth disc and outer roller pins. The first inner roller pins are meshed with the outer roller pins in a differential motion mode. The input shaft drives the first tooth disc to rotate through the input mechanism. The first tooth disc drives the output shaft to rotate through the output mechanism. Differential mesh of the first inner roller pins and the outer roller pins is adopted, speed reduction of input power is achieved, power obtained after speed reduction is conducted is transmitted through the first tooth disc, and finally, input power of speed reduction is output through the output mechanism. Due to the fact that the structure of the first inner roller pins and the outer roller pins is relatively simple and relatively convenient to replace, the maintenance difficulty can be lowered, consumption of the reducer is reduced, and the maintenance cost is reduced.

Description

technical field [0001] The invention relates to the technical field of reducers, in particular to an improved wobble reducer. Background technique [0002] At present, the more common swing reduction device on the market is the cycloidal pinwheel reducer. The existing cycloidal pin gear reducer adopts a planetary transmission structure with a small tooth difference, and the inner equidistant curve of the luffing epicycloid is used as the tooth profile curve of the planetary gear, and the circle is used as the tooth profile curve of the center gear. This structure can obtain a large reduction ratio, small size, relatively low noise, and high transmission efficiency. Compared with the general involute gear, the cycloid reducer does not produce addendum interference phenomenon, thus expanding its application range. [0003] After research, the inventor found that the traditional cycloidal pin gear reducer has complex cycloidal tooth profile processing technology, and the gear...

Problems solved by technology

[0003] After research, the inventor found that the traditional cycloidal pin gear reducer has complex cycloidal tooth profile processing technology, and the gear surface is easily worn, which leads to increased internal noise of the reducer and difficulty in replacing damaged parts.
