Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

The utility model provides a gear eccentric shaft wear-resisting structure 100, this structure is described in detail below with reference to fig. 1-3:

as shown in fig. 1 to 3, the wear-resistant structure 100 of the eccentric shaft of the gear of the present embodiment includes a gear 10 and a wear-resistant lining 20. Preferably, the gear 10 and the gasket 20 are of an integrally formed structure, no additional part is needed, the gasket 20 is directly pressed into the gear 10 during assembly, the operation is simple, and the product strength is reliable. Moreover, the gear 10 is made of plastic, the liner 20 is made of metal wear-resistant material, and the wear-resistant material of the liner 20 can effectively improve the wear resistance of the eccentric shaft and prolong the service life of the gear 10.

Specifically, referring to fig. 1-3, one side of the gear 10 of the present embodiment extends to form a gear shaft 11 with an eccentric structure along the axial direction, a first central axis of the gear 10 is spaced from a second central axis of the gear shaft 11 by a predetermined distance, and the two central axes are not located on the same straight line, so as to implement the eccentric structure of the gear shaft 11. The gear 10 is provided with a mounting hole 13 in the center, and the third central axis of the mounting hole 13 coincides with the first central axis of the gear 10. Wherein, the gear shaft 11 is a C-shaped step 111 along the circumferential direction; preferably, the gasket 20 is of a C-shaped opening structure, the gasket 20 is installed in cooperation with the step 111, the inner wall of the gasket 20 is attached to the outer wall of the step 111, and the gasket 20 protects the gear shaft 11 which is a plastic part, so that the wear resistance of the eccentric shaft is improved, the service life of the eccentric shaft is prolonged, and the service life of the whole gear 10 is prolonged.

Furthermore, the gear 10 of this embodiment is provided with a positioning groove 12 along the axial direction, the bottom surface of the pad 20 extends along the length direction to form a positioning arm 21, the positioning arm 21 is installed in the corresponding positioning groove 12, and the fixed installation of the pad 20 is realized by the matching installation of the positioning arm 21 and the positioning groove 12.

Referring to fig. 1-3, in the present embodiment, an end of the gear shaft 11 away from the gear 10 extends in a radial direction to form a blocking piece 112, an end surface of the gasket 20 is engaged with the blocking piece 112, and the blocking piece 112 is used for fixing the end surface of the gasket 20, so that the gasket 20 is more firmly mounted.
