A large transmission ratio silent transmission box and a sweeping machine for its application

Abstract

The invention discloses a machine with a large transmission ratio silent transmission box and a sweeping machine applied thereto. It comprises a motor driving and connected to a first pulley, and the first pulley is connected to a second pulley, wherein the second pulley is simultaneously As the planet carrier of the planetary gear system, the planet carrier is used as the power input end of the planetary gear system; the planetary gear system includes a number of planetary gears that are relatively eccentrically rotatable and installed on the second pulley, and each planetary gear is respectively connected to the sun gear. connected; the planetary gear revolves under the drive of the second pulley, and drives the sun gear to rotate eccentrically relative to the second pulley, and the sun gear mandrel fixed to the sun gear is used as the power output end of the transmission box; the present invention simultaneously The utility model has the technical effects of compact installation structure, large transmission ratio and silent transmission, and is therefore particularly suitable as a transmission box structure of sweeping machines (including sweeping robots).

Description

technical field [0001] The invention belongs to the technical field of transmission, and in particular relates to a silent transmission box with a large transmission ratio, and also relates to a sweeper applied to the transmission box. Background technique [0002] With people's continuous pursuit of improving living standards and continuous innovation of cleaning technology, sweepers (including sweeping robots) with automatic cleaning effects are more and more widely used in people's daily life. [0003] As the drive installation structure of the sweeper, the performance of the gearbox will directly determine the installation volume and noise performance of the sweeper. However, the existing gear box generally adopts the gear box structure of the gear meshing type. During the driving process, the noise generated by the gear meshing is relatively large; The larger the volume, the inherent noise problem will be further exacerbated. [0004] Therefore, the applicant wishes t...
