An improved wobble reducer

Abstract

Disclosed is an improved wobble plate decelerator, comprising a housing (101), an input shaft (102) and an output shaft, and further comprising an input mechanism, a decelerating mechanism and an output mechanism. The decelerating mechanism comprises a first inner needle roller (104), a first toothed disc (105) rotationally provided inside the housing (101), and an outer needle roller (131) annularly provided along the circumferential direction of the inner wall of the housing (101). The first inner needle roller (104) is embedded inside a first groove (106) of the first toothed disc (105) and is differentially meshed with the outer needle roller (131), the input shaft (102) drives the first toothed disc (105) to rotate via the input mechanism, and the first toothed disc (105) drives the output shaft to rotate via the output mechanism. The deceleration of an input power is realized by means of the differential meshing of the first inner needle roller and the outer needle roller, and then the decelerated power is transmitted by the first toothed disc, and finally the decelerated input power is output via the output mechanism. The first inner needle roller and the outer needle roller have a relatively simple structure and a relatively convenient replacement, thereby lowering the maintenance difficulties and saving the use and maintenance cost of the decelerator.

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.
