Description

Technical Field

[0001] This utility model relates to the field of motorcycle accessories technology, specifically to a motorcycle bearing dust cover. Background Technology

[0002] When a motorcycle is in normal operation, the dust seal of the bearing rotates with the wheel while the bushing block remains stationary. Over time, the dust seal is worn down by the bushing block, increasing the gap between the dust seal and the bushing block. This provides a pathway for dust and sand to enter, causing the front and rear bearings of the motorcycle to wear down due to the intrusion of dust and sand, resulting in a short service life for the bearings. Utility Model Content

[0003] (I) Problems to be solved

[0004] The technical problem to be solved by this utility model is to overcome the above-mentioned technical defects and provide a motorcycle bearing dust cover that is dustproof, well-sealed, and can independently discharge dust.

[0005] (II) Technical Solution

[0006] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a motorcycle bearing dust cover, including a shaft body and a bearing sleeved on the shaft body, wherein a dust cover is sleeved on the outer end of the bearing, and a dust cover inner sleeve fitted into the inner wall of the outer ring of the bearing is also connected between the bearing and the dust cover.

[0007] The dustproof inner sleeve has an L-shaped cross section, including a vertical wall section and a horizontal wall section. The vertical wall section is fitted between the outer ring and the inner ring of the bearing, and the horizontal wall section extends along the length of the shaft.

[0008] The dustproof outer sleeve is fitted onto the outside of the dustproof inner sleeve. One side abuts against the outer wall of the bearing outer ring, and the inner wall of the other side is connected to the transverse wall section by several interlocking plates, forming a flow channel structure between adjacent interlocking plates.

[0009] A dust-blocking component is also provided between the inner wall of the dustproof outer jacket and the vertical wall section of the dustproof inner jacket.

[0010] As an improvement, the outer wall of the dustproof inner sleeve transverse wall section is formed with a locking section whose diameter gradually decreases towards the flow channel structure.

[0011] As an improvement, a dustproof inclined wall is also formed at the end of the vertical wall section.

[0012] As an improvement, the dust-blocking assembly includes short and long drainage rings that are staggered on the outer wall of the vertical wall section and the inner wall of the dustproof jacket.

[0013] The outer wall of the short drainage ring forms an acute angle with the vertical wall section;

[0014] The outer wall of the long drainage ring forms an acute angle with the inner wall of the dustproof jacket.

[0015] As an improvement, the inner wall of the outer ring of the bearing is further recessed with a fitting groove, the vertical wall section of the dustproof inner sleeve is fitted into the fitting groove, and the outer end wall of the fitting groove is matched with the dustproof inclined wall.

[0016] (III) Beneficial Effects

[0017] The advantages of this utility model compared with the prior art are as follows: In this application, a dustproof outer jacket and a dustproof inner jacket are combined to form a dust-proof and flow-guiding space. While using short and long flow-guiding rings to block dust step by step, dust can also be guided and discharged, thus extending the service life. Attached Figure Description

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly associated with those skilled in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0025] To make the content of this utility model easier to understand, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0026] Please refer to the appendix carefully. Figure 1-2 A dust cover for a motorcycle bearing includes a shaft body 1 and a bearing 2 sleeved on the shaft body 1. A dust cover 3 is sleeved on the outer end of the bearing 2. A dust cover 4, which is fitted into the inner wall of the outer ring of the bearing 2, is also connected between the bearing 2 and the dust cover 3.

[0027] The dustproof inner sleeve 4 has an L-shaped cross-section, including a vertical wall section 5 and a horizontal wall section 6. The vertical wall section 5 is fitted between the outer ring and the inner ring of the bearing 2. The horizontal wall section 6 extends along the length of the shaft 1. The dustproof outer sleeve 3 is fitted onto the outside of the dustproof inner sleeve 4. One side abuts against the outer wall of the outer ring of the bearing 2. The inner wall of the other side is connected to the horizontal wall section 6 by several fitting plates. The adjacent fitting plates form a flow channel structure 7. A dust-blocking component is also provided between the inner wall of the dustproof outer sleeve 3 and the vertical wall section 5 of the dustproof inner sleeve 4.

[0028] The outer wall of the horizontal wall section 6 of the dustproof inner sleeve 4 forms a locking section 8 with a gradually decreasing diameter facing the flow channel structure 7, and the end of the vertical wall section 5 also forms a dustproof inclined wall 9. The inner wall of the outer ring of the bearing 2 is also recessed with a fitting groove 12. The vertical wall section 5 of the dustproof inner sleeve 4 is fitted into the fitting groove 12, and the outer end wall of the fitting groove 12 is matched with the dustproof inclined wall 9.

[0029] More specifically:

[0030] The dust-blocking assembly includes short drainage rings 10 and long drainage rings 11 that are staggered on the outer wall of the vertical wall section 5 and the inner wall of the dustproof jacket 3;

[0031] The outer wall of the short drainage ring 10 and the vertical wall section 5 form an acute angle;

[0032] The outer wall of the long drainage ring 11 forms an acute angle with the inner wall of the dustproof jacket 3.

[0033] When dust enters between the dustproof outer sleeve 3 and the dustproof inner sleeve 4, the dust falls into the short or long drainage ring. When the shaft 1 rotates and the motorcycle starts, the vehicle body vibrates, and the dust is shaken, causing it to slide along the outside of the short or long drainage ring to the lower end. At this time, due to its acute angle setting, the dust slides out step by step, ensuring its dustproof performance.
