Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Fig. 1 to Fig. 2 is referred to, the utility model provides a kind of technical scheme：Including cross axle 1, outer ring 2, needle roller 3 and
Sealing structure, the head of cross axle 1 include the axle journal 11, first step 12 and the second step 13 that are sequentially connected, wherein, axle journal
11st, the external diameter of first step 12 and second step 13 differs, in the present embodiment, axle journal 11, first step 12 and second
The external diameter of rank 13 gradually increases, and adjacent successively seamlessly transits between the two.
Needle roller 3 is simultaneously with axle journal 11 and outer ring 2 against outer ring 2 is arranged at the head of cross axle 1, and is used to close ten
The head of word axle 1, sealing structure include oil sealing 4, skeleton 5 and dust cover 6, longitudinal cross-section " L " type of skeleton 5, and the mouth of skeleton 5
Portion's outward bending forms the flange projection 51 of ring-type, and gap is formed between flange projection 51 and outer ring 2.Skeleton 5 passes through pressure pressure
Enter the oral area of outer ring 2, fixed by interference fit.
Wherein, in the present embodiment, oil sealing 4 and skeleton 5 are integrally connecteds.Skeleton 5 and the oral area interference fit shape of outer ring 2
Into fixation, oil sealing 4 is provided with the first lip 41 coordinated with first step 12 and the second lip 42 and for coordinating with dust cover 6
The 3rd lip 43.
Specifically, the first lip 41 extends towards the bottom direction of outer ring 2, the first lip 41 is matched somebody with somebody with the interference of first step 12
Merge the angle 30 °~60 ° of formation between first step 12.Preferably, the second lip 42 prolongs along the oral area direction away from outer ring 2
Stretch, the second lip 42 and second step 13 are interference fitted and 30 °~60 ° of angle formed between first step 12.
First lip 41 and the second lip 42 are oppositely arranged each other, and the entrance of leakage and external dust for grease has
Dual sealing functions.
The second step 13 of dust cover 6 and cross axle 1 is interference fitted, and the one of the close flange projection 51 of dust cover 6
End is provided with projection, and projection is embedded between flange projection 51 and outer ring 2, prevents dust cover 6 from coming off.Dust cover 6 has inclined-plane
61, the 3rd lip 43 extends towards the direction of dust cover 6 and coordinated with inclined-plane 61.3rd lip 43 and the interference of 6 inclined-plane of dust cover 61
Coordinate, as first of sealing for preventing external dust intrusion needle bearing.
Preferably, 30 °~75 ° of angle is formed between inclined-plane 61 and second step 13.Shape between 3rd lip 43 and inclined-plane 61
