Structure for eliminating axial clearance

Abstract

The utility model discloses a structure for eliminating an axial clearance, which comprises a solid elastic gasket and a sleeve, the sleeve and the solid elastic gasket are arranged on a rotating shaft of a motor, and the solid elastic gasket is partially sunk in the sleeve. According to the utility model, an original hollow elastic structure is eliminated and is changed into a combined gap eliminating structure of the solid elastic gasket and the sleeve, so that the gap eliminating requirement can be met, and the stability is improved. Compared with an original hollow elastic structure, the combined gap eliminating structure of the solid elastic gasket and the sleeve has the advantages that the service life is prolonged, and meanwhile, the manufacturing cost is reduced. Compared with an original hollow elastic structure, the die of the solid elastic gasket is simple in manufacturing die, less in material consumption, better in planeness and perpendicularity compared with the original hollow elastic structure, stable in operation of a motor, and beneficial to noise improvement of the motor.

Description

Technical Field

[0001] This utility model relates to the field of motor technology, and in particular to a structure for eliminating axial clearance. Background Technology

[0002] See Figure 1 The existing gap-eliminating structure basically adopts a hollow elastic structure1, which is not strong enough and is prone to causing unstable motor operation and abnormal noise during motor operation. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a structure with good stability for eliminating axial clearance, which is caused by insufficient use of hollow elastic body in the motor clearance elimination structure, resulting in unstable motor operation and easy generation of abnormal motor noise.

[0004] The technical problem to be solved by this utility model can be achieved through the following technical solution:

[0005] A structure for eliminating axial clearance includes a solid elastic washer and a sleeve, the sleeve and the solid elastic washer being mounted on the shaft of a motor, the solid elastic washer being partially submerged in the sleeve.

[0006] In a preferred embodiment of the present invention, a plurality of grooves are provided on the outer periphery of the solid elastic pad.

[0007] By adopting the above technical solution, this utility model eliminates the original hollow elastic structure and replaces it with a combination of a solid elastic gasket and a sleeve to eliminate gaps, thus achieving both gap elimination and increased stability. Compared to the original hollow elastic structure, the combination of the solid elastic gasket and sleeve in this utility model increases service life and reduces manufacturing costs. The mold for the solid elastic gasket in this utility model is simpler and uses less material than the mold for the original hollow elastic structure. Its flatness and perpendicularity are also better than the original hollow elastic structure, resulting in smoother motor operation and improved motor noise reduction. Attached Figure Description

[0009] Figure 2 This is a reference diagram showing the structure of this utility model for eliminating axial clearance in use.

[0010] Figure 3 This is a schematic diagram of the structure for eliminating axial clearance according to this utility model. Detailed Implementation

[0011] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0012] See Figure 2 and Figure 3 The figure shows a structure for eliminating axial clearance, comprising a solid elastic washer 10 and a sleeve 20. The sleeve 10 and the solid elastic washer 20 are mounted on the rotating shaft 21 of the motor 30, with the solid elastic washer 10 partially submerged in the sleeve 10. Several grooves 11 are provided on the outer periphery of the solid elastic washer 10.

[0013] This utility model eliminates the original hollow elastic structure and replaces it with a combination of solid elastic gasket 10 and sleeve 20 to eliminate gaps, which can meet the requirements of eliminating gaps and increase stability.
