Abstract

The utility model discloses a multipoint meshing inner and outer gear reducer, comprising a central input shaft, a driving gear, driven gears, an output inner gear, a central output shaft, an input end enclosure and an output end enclosure, wherein the driving gear is fixed on the central input shaft; the central input shaft is fixed on the input end enclosure by a bearing; the driven gears are fixed on the input end enclosure by a gear shaft and a bearing; the output inner gear is fixed on the central output shaft; the central output shaft is fixed on the output end enclosure by a bearing. The multipoint meshing inner and outer gear reducer is characterized in that at least more than two driven gears are symmetrically distributed along the circumference of the driving gear and are meshed with the driving gear, wheel teeth at the other faces of the driven gears are internally meshed with the output inner gear of the output shaft end, and the torque is output.

Description

The inside and outside gear reduction unit of multi point engagement

Technical field

The utility model and a kind of gear reduction unit, the specifically inside and outside gear reduction unit of a kind of multi point engagement.

Background technique

At present, traditional two pitch wheels of gear reduction unit are by monolateral tooth transmitting torque, and the moment of torsion transmitting is less.

Summary of the invention

The technical problems to be solved in the utility model is to provide a kind of inside and outside gear reduction unit of multi point engagement of transmitting large torque.

In order to solve the problems of the technologies described above, the inside and outside gear reduction unit of multi point engagement of the present utility model comprises center input shaft, driving gear, driven gear, output inner gear, center output shaft, input end casing, output terminal casing, driving gear is fixed on the input shaft of center, center input shaft is fixed on input end casing by bearing, driven gear is also fixed on input end casing by gear shaft and bearing, output inner gear is fixed on the output shaft of center, center output shaft is fixed on output terminal casing by bearing, it is characterized in that, the at least symmetrical plural driven gear of circumference along driving gear engages with driving gear, the gear teeth of the another side of driven gear engage with in the output inner gear of output shaft end, and moment of torsion is exported.

Adopt the design's beneficial effect to be: by multiple driven gears from multiple orientation and driving gear and internal gear engagement output torque, thereby improved the larger moment of torsion output capability of gear of identical modulus and material.
