Motor components and robot vacuums

Abstract

The invention discloses a motor assembly and a sweeping robot. The motor assembly includes a casing; the motor and the reduction box are both arranged in the casing. The reduction box includes a box body, a reduction mechanism, a limit shaft, an output shaft and an axial limit mechanism. The reduction mechanism is connected to the rotating shaft and the output shaft respectively, the limit shaft is connected to the reduction mechanism, and the axial limit mechanism is sleeved on the output shaft. The side wall of the gear box is in contact with the deceleration mechanism and the box body; the first end cover is set at the end of the motor away from the gear box to seal the opening of one end of the housing; the second end cover is set at the end of the gear box away from the motor, and the second end cover It is fixedly connected with the box body and the shell to seal the opening at the other end of the shell; the axial support includes a rotatably connected inner ring and an outer ring, the inner ring is sleeved on the outer wall of the first end cover, and the outer ring is in contact with the inner wall of the drum connected; the fixing part is fixedly connected with the drum, and is connected with the first end cover in rotation. The technical solution of the invention aims at improving the service life of the motor assembly.

Description

technical field [0001] The invention relates to the technical field of sweeping robots, in particular to a motor assembly and a sweeping robot using the motor assembly. Background technique [0002] Sweeping robots can replace people to quickly clean the ground, and can effectively relieve people's cleaning pressure and are favored. The sweeping robot in the related art uses a roller motor as a driving component of the sweeping robot. The driving components include a motor and a gearbox, etc., and the motor and the gearbox need to cooperate with the roller to roll the roller relative to the sweeping robot, so as to realize the cleaning operation of the brush on the outside of the driving roller. The stability of the driving components directly affects the cleaning effect and service life of the sweeping robot. Moreover, there is a lot of dust and accumulated water in the working environment of the sweeping robot, and its working environment is harsh. The sealing and waterp...
