Abstract
The utility model relates to a universal joint assembly part and especially relates to a cold extruding universal joint bearing sleeve subjected to less cutting or no cutting. The cold extruding universal joint bearing sleeve is used for solving the technical problems of the prior art that a main body of a bearing sleeve of a universal joint is formed in a forging form, and then an inner circle, an outer circle, an inner bottom hole and an outer bottom hole of the bearing sleeve are processed in a cutting form, the process is complex, more raw materials are consumed, the production cost is higher and the like. The cold extruding universal joint bearing sleeve subjected to less cutting or no cutting comprises a bearing sleeve main body (1) and is characterized in that the bearing sleeve main body (1) is formed in the cold extruding form; an inner bottom hole (2) is cold-extruded at the bottom face in the bearing sleeve main body; an oil groove (3) is arranged at a transition part between the inner wall and inner bottom face of the bearing sleeve main body (1); and an external bottom hole (4) is cold-extruded in the bottom of the exterior of the bearing sleeve main body.
Description
Technical field
The utility model relates to a kind of universal joint assembly component, especially relates to a kind of cold hobbing and cuts less or do not have a cutting universal joint shaft bearing sleeve.
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 in the bearing housing that this universal joint adopts, all be to accomplish body through forging, and then with the interior circle that cuts out bearing housing, cylindrical, interior bottom outlet, outer bottom outlet, not only operation is comparatively numerous and diverse, and the raw material that consumed are more, cost of production is bigger.
The model utility content
The utility model provides a kind of cold hobbing and cuts less or do not have a cutting universal joint shaft bearing sleeve; It mainly is to solve in the bearing housing of existing in prior technology universal joint employing; All be to accomplish body, and then with the interior circle that cuts out bearing housing, cylindrical, interior bottom outlet, outer bottom outlet, not only operation is comparatively numerous and diverse through forging; And the raw material that consumed are more, the technical problem of the bigger grade of cost of production.
The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals:
The cold hobbing of the utility model is cut less or is not had a cutting universal joint shaft bearing sleeve; Comprise the bearing housing body; Described bearing housing body is formed by cold hobbing; The bottom surface cold-extruded of bearing housing body interior is pressed with interior bottom outlet, and the inwall of bearing housing body and the transition position of inner bottom surface are provided with oil storage tank, and the bottom surface cold-extruded of bearing housing body exterior is pressed with the outer bottom hole.Oil storage tank can be stored in fluid here, makes things convenient for the rolling of needle roller.And oil storage tank can also hold the end of needle roller.Cross axis faces in the universal joint can have oil groove, and oil storage tank can be communicated with oil groove.The inside and outside circle of bearing housing body, interior bottom outlet, outer bottom outlet are all formed by the cold hobbing once-through, therefore need not cutting, have practiced thrift cost of production.
As preferably, the outer wall on described bearing housing body top is provided with the dust-proof cover mounting groove, and the dust-proof cover mounting groove includes the cell body of section for " L " type, the two ends of cell body respectively through a conical surface transition to bearing housing body cylindrical and upper-end surface.In the dust-proof cover mounting groove dust-proof cover can be installed, dust-proof cover is located between trunnion journal and the bearing housing end face, can prevent that dust from entering into universal joint assembly inside by the slit between trunnion journal and the bearing housing end face.
As preferably, all be provided with chamfering on the outer wall of described bearing housing body bottom, the inwall on bearing housing body top.Chamfering can conveniently be encased in bearing housing in the Hooke's joint, prevents that the bearing housing edge from scratching other automotive component.
Therefore; The utility model with disposable interior circle, cylindrical, interior bottom outlet, the outer bottom outlet of processing of bearing housing, has reduced the cutting of internal circle, cylindrical, interior bottom outlet, outer bottom outlet through cold hobbing, can not only enhance productivity; Can also reduce cost of production, simple and reasonable for structure.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the utility model.
Component, position and numbering among the figure: bearing housing body 1, interior bottom outlet 2, oil storage tank 3, outer bottom outlet 4, dust-proof cover mounting groove 5, chamfering 6.
Embodiment
Pass through embodiment below, and combine accompanying drawing, do further bright specifically the technological scheme of the utility model.
Embodiment: this routine cold hobbing is cut less or is not had a cutting universal joint shaft bearing sleeve; Like Fig. 1; A bearing housing body 1 is arranged, and the bearing housing body is formed by cold hobbing, and the bottom surface cold-extruded of bearing housing body interior is pressed with interior bottom outlet 2; The inwall of bearing housing body and the transition position of inner bottom surface are provided with oil storage tank 3, and the bottom surface cold-extruded of bearing housing body exterior is pressed with outer bottom hole 4.The outer wall on bearing housing body top is provided with dust-proof cover mounting groove 5, and the dust-proof cover mounting groove includes the cell body of section for " L " type, and bearing housing body cylindrical and upper-end surface are arrived through a conical surface transition respectively in the two ends of cell body.All be provided with chamfering 6 on the inwall on the outer wall of bearing housing body bottom, bearing housing body top.
During use, the needle roller of in bearing housing body 1, packing into is contained in cross-member ends with the bearing housing body then and gets 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.
