Abstract
The utility model relates to a universal joint assembly, in particular to a universal joint assembly with double-contract oil seals, which mainly aims at solving the technical problems that in the prior art, a universal joint has poor sealing performance because a cross shaft of the universal joint has no inclined plane and the contact performance between a sealing part and the cross shaft is poor; dust easily entering the inside of the universal joint assembly results in abrasion between the cross shaft and a bearing seat; and the like. The universal joint assembly with the double-contract oil seals comprises a cross joint provided with an oil cup. Four end portions of the cross joint are respectively sleeved in an outer ring, a plurality of rolling pins are arranged between the insides of the outer rings and the end portions of the cross joint, an inclined plane is arranged at the position of a shaft neck of the cross joint, metal frameworks are arranged at the inner ends of the outer rings, oil seals are fixed on the metal frameworks and respectively provided with two sealing lips, one sealing lips are contacted with the inclined plane, and the other sealing lips are contacted with the outer surfaces of the end portions of the cross joint, and spring sheets are arranged between the metal frameworks and the rolling pins.
Description
Technical field
The utility model relates to a kind of universal joint assembly, especially relates to a kind of universal joint assembly with two contact seals.
Background technique
Universal-joint cross trunnion of the prior art is generally all formed by middle axis body and with the arm that middle axis body links into an integrated entity.Chinese patent discloses a kind of high tenacity Hooke's joint (notice of authorization number: CN 2464984Y); It comprises cross axle and is arranged on the needle roller around the cross axle spindle nose and puts and outer ring that needle roller is outer; The end of outer ring is provided with packing holder, on said packing holder, is provided with seal ring skeleton and seal placed on it; And the inboard of described seal is provided with tilting outer lip and inside middle lip and the inner lip of lip successively, and two lips contact with the axle journal of cross axle; Tiltedly be provided with the grinding undercut of annular between internal face and the needle roller end face ring, the plane of technology groove connects really in flat end needle rollers end face and the bearing.But the cross axle of this universal joint is not provided with the inclined-plane, and the contact of Sealing and cross axle is relatively poor, so its sealability is relatively poor, and dust enters into universal joint assembly inside easily, makes to be easy to generate wearing and tearing between cross axle and the bearing support.
The model utility content
The utility model provides a kind of universal joint assembly with two contact seals; It mainly is that the cross axle that solves the existing in prior technology universal joint is not provided with the inclined-plane; The contact of Sealing and cross axle is relatively poor; Therefore its sealability is relatively poor, and dust enters into universal joint assembly inside easily, makes the technical problem that is easy to generate wearing and tearing etc. between cross axle and the bearing support.
The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals:
A kind of universal joint assembly with two contact seals of the utility model comprises the cross joint, and described cross joint is provided with lubricating cup; Four ends of cross joint all are socketed with an outer ring, are provided with some needle rollers between inside, outer ring and the cross joint end, and the axle journal place of cross joint is provided with the inclined-plane; The inner, outer ring is provided with metal frame; Be fixed with oil sealing on the metal frame, oil sealing has two sealing lips, and one of them sealing lip contact is on the inclined-plane; Another sealing lip contact is provided with spring sheet in the outer surface of cross joint end between metal frame and the needle roller.The inside of outer ring can have oil storage tank, is used for preserving lubricating grease, thereby guarantees that assembling back needle roller rotates flexibly, oil sealing is intact.Oil sealing can prevent that dust from entering into universal joint assembly inside, also can prevent that the inner fluid of universal joint assembly from flowing to outside the universal joint through the slit of cross joint with the outer ring simultaneously.Spring sheet not only can play the effect of location needle roller, can also oil sealing be pressed in the axle journal place of cross axle, and sealing effect is better.
As preferably, described needle roller is double needle roller, and needle roller is rollably more smooth and easy like this.
As preferably, described oil sealing is provided with dust-proof cover outward.Dust-proof cover can prevent further that dust from entering into Hooke's joint inside.
As preferably, be provided with pad between the end face of described cross joint end and the inside of outer ring.Pad can be processed by nylon, like this needle roller when rotated, needle roller and cross joint end can not touch the inside of outer ring, reduces wear, and has reduced noise.
Therefore, the utility model is provided with the inclined-plane at the axle journal place of cross axle, adds oil sealing mechanism at the place, inclined-plane, and sealing is better, has prevented that dust from entering into universal joint assembly inside, and is simple and reasonable for structure.

Embodiment
Pass through embodiment below, and combine accompanying drawing, do further bright specifically the technological scheme of the utility model.
Embodiment: a kind of universal joint assembly of this example with two contact seals; Like Fig. 1, Fig. 2, a cross joint 1 is arranged, the cross joint is provided with lubricating cup 2; Four ends of cross joint all are socketed with an outer ring 3, are provided with pad 10 between the end face of cross joint end and the inside of outer ring.Be provided with some needle rollers 4 between inside, outer ring and the cross joint end, needle roller is double needle roller.The axle journal place of cross joint is provided with inclined-plane 5, and the inner, outer ring is provided with metal frame 6, is fixed with oil sealing 7 on the metal frame, and oil sealing is provided with dust-proof cover 9 outward.Oil sealing has two sealing lips, and one of them sealing lip contact is on inclined-plane 5, and another sealing lip contact is provided with spring sheet 8 in the outer surface of cross joint end between metal frame and the needle roller.
During use, the utility model interior of motor vehicles of packing into is got final product.
The above is merely the specific embodiment of the utility model; But the structure characteristic of the utility model is not limited thereto; Any those skilled in the art is in the field of the utility model, and variation of being done or modification all are encompassed among the claim of the utility model.
