Description

Technical Field

[0001] This utility model relates to the field of shaft sleeve technology for height-adjustable table motors, and in particular to a shaft sleeve structure for height-adjustable table motors. Background Technology

[0002] The motor of an electric height-adjustable desk is the core component, responsible for driving the desk legs to raise and lower to achieve height adjustment. The bushing structure is a key mechanical component connecting the motor output shaft and the lifting transmission components, directly affecting the smoothness of transmission, noise, and lifespan.

[0003] Currently, the gears in the motor of the height-adjustable desk are directly installed between the gearbox and the reducer. During long-term operation, the gears will rotate continuously, resulting in a lot of wear between them and gradually reducing the stability of the reducer support. To address this, a bushing structure for the height-adjustable desk motor is proposed. Summary of the Invention

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a bushing structure for a height-adjustable table motor.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A bushing structure for a height-adjustable table motor includes a gearbox body, a cover plate installed on one side of the gearbox body, a second bushing installed inside the cover plate, a first bushing installed inside the gearbox body, a helical gear connecting the second bushing and the first bushing, and a central support block installed on the outer side of the helical gear.

[0007] Preferably, a first central groove is formed in the gearbox body, the first bushing is installed in the first central groove, and a plurality of first reinforcing ribs are arranged in a ring on the outer side of the first central groove, and the first reinforcing ribs are installed on the inner wall surface of the gearbox body.

[0008] Preferably, the cover plate has a second central groove, the second bushing is connected in the second central groove, and a plurality of second reinforcing ribs are arranged in a ring on the outer side of the second central groove, the second reinforcing ribs being located on the inner wall surface of the cover plate.

[0009] Preferably, the gearbox body and the cover plate are provided with a plurality of mounting slots, and the mounting slots are connected by threaded screws.

[0010] Preferably, there are two central support blocks, which are fixedly installed on both sides of the helical gear and connected to the first bushing and the second bushing, respectively.

[0011] The beneficial effects of this utility model are:

[0012] This design allows for convenient support of both sides of the helical gear via a central support block. The first and second bushings reduce the coefficient of friction with the central support block, thus lowering the frequency of damage. The cover plate and gearbox body secure the helical gear for positioning.

[0013] This solution reduces the possibility of rapid wear on both sides of the helical gear during prolonged contact, lowers the likelihood of damage to the helical gear, improves the stable support effect of the gearbox on the helical gear, and also improves the wear resistance between the two, thus achieving a longer service life for the helical gear and indirectly saving maintenance costs for the equipment.
