Abstract
The utility model relates to a component of a universal-joint assembly, in particular to a special universal-joint cross trunnion moulded once by cold extrusion for a transmission shaft, mainly solving the technical problems of complex working procedures, high consumption for raw materials, higher production cost and the like caused by finishing a body via forging, and then machining the trunnion body of a cross trunnion via cutting in the cross trunnion used by a universal joint existing in the prior art. The special universal-joint cross trunnion moulded once by cold extrusion for the transmission shaft, disclosed by the utility model, comprises a cross trunnion body (1) and a trunnion body (2) and is characterized in that the cross trunnion body (1) and the trunnion body (2) are moulded once by cold extrusion, wherein a screw hole (3) is disposed on the end part of the trunnion body (2), and an oil groove (4) is disposed on the outer end surface of the trunnion body (2).
Description
Technical field
The utility model relates to a kind of universal joint assembly component, especially relates to the special-purpose universal-joint cross trunnion of a kind of cold hobbing once-through transmission shaft.
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 cross axle that this universal joint adopts, all be to accomplish body through forging, and then with the axis body that cuts out cross axle, 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 the special-purpose universal-joint cross trunnion of a kind of cold hobbing once-through transmission shaft; It mainly is to solve in the cross axle of existing in prior technology universal joint employing; All be to accomplish body, and then with the axis body that cuts out cross axle, 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 special-purpose universal-joint cross trunnion of the cold hobbing once-through transmission shaft of the utility model comprises cross axle body and axis body, and described cross axle body and axis body are formed by the cold hobbing once-through, and the end of axis body is provided with screw, has oil groove on the exterior edge face of axis body.Axis body end face in the universal joint can have oil groove, and the oil storage tank in the bearing housing can be communicated with oil groove, in the oil groove after the oiling, and can be so that the rolling of needle roller be more smooth and easy.Cross axle body and axis body are all formed by the cold hobbing once-through, therefore need not cutting, have practiced thrift cost of production.
As preferably, described axis body inner with the cross axle body between be arc transition, can increase the intensity that is connected between axis body the inner and the cross axle body like this.
As preferably, the axle journal place of described axis body is provided with the inclined-plane.After axis body was installed bearing housing, the inner oil sealing of bearing housing can touch the inclined-plane, can prevent that like this fluid in the bearing housing from leaking.
As preferably, described oil groove is more than 2, and the angle of oil groove both sides inwall is 50-70 °.Oil groove quantity is more, can make fluid fluidly more smooth and easy.
Therefore, the utility model with disposable cross axle body and four axis bodies of processing of bearing housing, has reduced the cutting to cross axle body and four axis bodies through cold hobbing, can not only enhance productivity, and can also reduce cost of production, and is 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 cross-sectional view of Fig. 1.
Component, position and numbering among the figure: cross axle body 1, axis body 2, screw 3, oil groove 4, inclined-plane 5.
Embodiment
Pass through embodiment below, and combine accompanying drawing, do further bright specifically the technological scheme of the utility model.
Embodiment: the special-purpose universal-joint cross trunnion of this routine cold hobbing once-through transmission shaft; Like Fig. 1, Fig. 2, a cross axle body 1 and axis body 2 are arranged, cross axle body and axis body are formed by the cold hobbing once-through; The end of axis body is provided with screw 3; Have oil groove 4 on the exterior edge face of axis body, oil groove is 3, and the angle of oil groove both sides inwall is 60 °.Between axis body the inner and the cross axle body is arc transition, and the axle journal place of axis body is provided with inclined-plane 5.
During use, the needle roller of in bearing housing, packing into, axis body 2 outer ends that then the bearing housing body are contained on the cross axle body 1 get 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.
