Abstract
The utility model relates to a universal joint assembly, in particular to a universal joint assembly with high sealing property, which mainly aims at solving the technical problems that a cross axle of a universal joint in the prior art is not provided with an inclined plane, and the contact performance of a sealing element and the cross axle is poorer, so that the sealing performance of the universal joint is poorer, dust can easily enter the universal joint assembly, abrasion is generated between the cross axle and a bearing seat, further, the service life of the universal joint assembly is influenced, and the like. The universal joint assembly with high sealing property comprises a cross joint (1), and is characterized in that the cross joint (1) is provided with an oil cup (2); the four ends of the cross joint are respectively sheathed and connected with an outer ring (3); a plurality of roller pins (4) are arranged between the interiors of the outer rings and the ends of the cross joint; the shaft neck of the cross joint (1) is provided with the inclined plane (5); and the inclined plane is provided with an oil seal mechanism.
Description
Technical field
The utility model relates to a kind of universal joint assembly, especially relates to a kind of high leak tightness universal joint assembly.
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 produce wearing and tearing between cross axle and the bearing support, influences working life.
The model utility content
The utility model provides a kind of high leak tightness universal joint assembly; 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, so its sealability is relatively poor, and dust enters into universal joint assembly inside easily; Make between cross axle and the bearing support to produce wearing and tearing, influence the technical problem in working life etc.
The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals:
The high leak tightness universal joint assembly 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; Be provided with some needle rollers between inside, outer ring and the cross joint end, the axle journal place of cross joint is provided with the inclined-plane, and the inclined-plane is provided with oil sealing mechanism.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.The utility model processes the inclined-plane at the axle journal place of cross axle, and adds oil sealing mechanism at the step place, makes sealing better, and working life is longer.
As preferably, described oil sealing mechanism comprises that section is the metal frame of " L " type, is fixed with oil sealing on the metal frame; Oil sealing has two sealing lips; One of them sealing lip contact is on the inclined-plane, and another sealing lip contact is in the outer surface of cross joint end, and oil sealing is provided with the axle bowl outward.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.
As preferably, the two ends of described needle roller are tip all, are provided with the needle roller back-up ring in the outer ring.The two ends of needle roller all are tip, and the one of which end in contact is the technology groove plane in the outer ring, and the other end is fixed by the tailor-made oil sealing; Needle roller is when rolling like this, and its two ends are less with the area that outer ring or cross joint contact, and frictional force reduces like this; Be difficult for falling pin, it is more smooth and easy to make that needle roller rolls.
Therefore, the utility model is provided with the inclined-plane through the axle journal place at cross axle, and adds oil sealing mechanism at the place, inclined-plane; Sealing is better, prevented that dust from entering into universal joint assembly inside, and the needle with round end that will use originally replaces with the tip needle roller; Make the area of contact of needle roller and cross joint, outer ring reduce; Thereby needle roller is rollably more flexible, and the utilization efficiency of cross joint is higher, simple and reasonable for structure.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the utility model;
Accompanying drawing 2 is A portion structure for amplifying schematic representation of Fig. 1.
Component, position and numbering among the figure: cross joint 1, lubricating cup 2, outer ring 3, needle roller 4, inclined-plane 5, metal frame 6, oil sealing 7, axle bowl 8, needle roller back-up ring 9.
Embodiment
Pass through embodiment below, and combine accompanying drawing, do further bright specifically the technological scheme of the utility model.
Embodiment: the high leak tightness universal joint assembly that this is routine; 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; Be provided with some needle rollers 4 between inside, outer ring and the cross joint end, the two ends of needle roller all are tip, are provided with needle roller back-up ring 9 in the outer ring 3.The axle journal place of cross joint is provided with inclined-plane 5; The inclined-plane is provided with oil sealing mechanism, and oil sealing mechanism comprises that section is the metal frame 6 of " L " type, is fixed with oil sealing 7 on the metal frame; Oil sealing has two sealing lips; One of them sealing lip contact is on inclined-plane 5, and another sealing lip contact is in the outer surface of cross joint end, and oil sealing is provided with axle bowl 8 outward.
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.
