Problems solved by technology

[0002] At present, due to the advantages of small size, light weight and low cost, high-speed motors are widely used in large quantities, and because the speed of high-speed motors is relatively high, it is necessary to achieve power output through a reduction mechanism with a large reduction ratio. However, if the existing reduction mechanism needs to achieve a larger reduction ratio, there will be a problem that the volume will increase accordingly, making the overall weight of the reduction mechanism heavier

Abstract

The invention discloses a reducing mechanism and an axle. The main shaft of the reducing mechanism is configured to be able to rotate around the axis of the reducing mechanism, and a sun gear is installed on the main shaft so as to rotate along the main shaft; a first planet shaft is fixedly arranged, and a first planet gear is installed on the first planet and engages with the sun gear; the internal teeth of the first ring gear engage with the first planet gear, and the external teeth of the first ring gear engage with a second planet gear; a second ring gear is fixedly arranged, and the second planet gear engages with the internal teeth of the second ring gear to rotate around the second ring gear; a second planet shaft is fixedly installed on a planet carrier, and the second planet gearis installed on the second planet shaft to drive the planet carrier to rotate during a process that the second planet rotates around the second ring gear; the planet carrier is connected with the flange of a differential mechanism to drive the differential mechanism to rotate. The reducing mechanism can increase the reduction ratio without increasing the volume, and is beneficial to reducing thewhole weight of the reducing mechanism.

Description

technical field [0001] The invention relates to the technical field of speed reducers, in particular to a speed reduction mechanism and a vehicle axle. Background technique [0002] At present, due to the advantages of small size, light weight and low cost, high-speed motors are widely used in large quantities, and because the speed of high-speed motors is relatively high, it is necessary to achieve power output through a reduction mechanism with a large reduction ratio. However, if the existing reduction mechanism needs to achieve a larger reduction ratio, there will be a problem that the volume will increase accordingly, making the overall weight of the reduction mechanism heavier. Contents of the invention [0003] The object of the present invention is to overcome the problems existing in the prior art and provide a speed reduction mechanism and an axle. overall weight. [0004] In order to achieve the above object, the present invention provides a reduction mechanis...
