Description

Technical Field

[0001] This utility model relates to the field of lifting motor technology, specifically a lifting motor that is easy to install and disassemble. Background Technology

[0002] When the motor body is working, it drives the gears in the gearbox assembly to rotate via the gear shaft, which in turn drives the lead screw to rise or fall. A lifting motor typically includes a motor body, a gearbox assembly, and a lead screw. The lower end of the motor body is mounted on the gearbox assembly, and the lead screw passes through the gearbox assembly. The gearbox assembly contains multiple gears and rotating shafts, among other components.

[0003] Referring to Chinese Patent Publication No. CN208820611U, published on May 3, 2019, a lifting motor is disclosed, including a motor body, a gearbox assembly, and a lead screw. The lower end of the motor body is mounted on the gearbox assembly, and the lead screw passes through the gearbox assembly. The gearbox assembly includes an upper gearbox shell and a lower gearbox shell that are matched vertically. Inside the gearbox assembly, there are upper O-rings, upper flat bearings, lead screw gears, lower flat bearings, and lower O-rings that contact each other sequentially from top to bottom. The upper surface of the upper O-ring contacts the inner surface of the upper gearbox shell, and the lower surface of the lower O-ring contacts the inner surface of the lower gearbox shell. The motor body drives the gearbox assembly to drive the lead screw to rise or fall. The advantage of this utility model is that because there are upper and lower O-rings, and they are in contact with the inner surfaces of the upper and lower gearbox shells respectively, when the lead screw moves up and down, the upper and lower flat bearings inside the gearbox assembly will not wobble axially, reducing the vibration of the lifting motor, lowering the noise of the lifting motor, and making the up and down reciprocating motion of the lead screw smoother.
