Feature of the present utility model and advantage will be described in detail by reference to the accompanying drawings by embodiment.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model one preferred embodiment;
Fig. 2 is the cross-sectional schematic of the utility model one preferred embodiment axle sleeve part.
Embodiment
For making the purpose of this utility model, technological scheme and advantage clearly understand, below by accompanying drawing and embodiment, the utility model is further elaborated.But should be appreciated that, specific embodiment described herein, only in order to explain the utility model, is not limited to scope of the present utility model.In addition, in the following description, the description to known features and technology is eliminated, to avoid unnecessarily obscuring concept of the present utility model.
Consult Fig. 1 and Fig. 2, the utility model embodiment provides a kind of Hooke's joint assembly being applicable to Intelligent assembly quick position, it comprises cross axle axis body 1, cross axle axis body 1 is provided with axle journal 2, axle journal 2 is arranged with axle sleeve 3, equally distributed needle roller 4 is provided with between the inside of axle sleeve 3 and axle journal 2 outer wall, axle sleeve 3 front opening place is bent to form baffle ring 31 to axle journal 2 direction, gap is left between the inner side surface of baffle ring 31 and the outer side surface of axle journal 2, be provided with oil sealing 5 between needle roller 4 and baffle ring 31, the surface that baffle ring 31 contacts with oil sealing 5 is provided with limit structure 32.
The Hooke's joint assembly that the utility model provides, it is inner that its oil sealing 5 is fixed on axle sleeve 3 by needle roller 4 and baffle ring 32, thus can save existing double sealing structure, makes Hooke's joint structure simple, easy to process; Further, limit structure 32 and oil sealing 5 matching form close, and fix oil sealing 5 better, make oil sealing 5 embed the inside of axle sleeve 3, eliminate the potential safety hazard of the Hooke's joint sealing effect difference caused because oil sealing 5 loosens, improve the working life of Hooke's joint.Meanwhile, due to the introducing of full-automatic Assembling Production technology, the existing oil sealing 5 being placed in axle sleeve 3 outside cannot meet the needs of assembling automatically completely.Therefore, this kind of structure is particularly useful for the full-automatic Assembling Production of Hooke's joint, greatly reduces the operation that manual assembly of technician etc. is unnecessary, reduces labour cost, improve the manufacturing efficiency of Hooke's joint.
Particularly, oil sealing 5 is X-shaped seal ring.This oil sealing 5 comprises 4 seal lips 52 and the arc-shaped recess 51 between every two seal lips 52, that is, the limit structure 32 closed with its matching form is provided with arc convex 322, groove 321 is all provided with in the both sides of arc convex 322, wherein, groove 321 cooperatively interacts with wherein two seal lips 52 of oil sealing 5, and the arc-shaped recess 51 simultaneously between arc convex 322 and this two seal lips 52 cooperatively interacts.This kind of structure make use of the particularity of X-shaped ring structure, ensures just can obtain surface of contact large as far as possible when pressure is less between axle sleeve 3 and oil sealing 5, more firm when oil sealing 5 is connected with miscellaneous part, strengthens the sealing effect of Hooke's joint.
The fillet radius of the end face of Hooke's joint axle journal 2 is set to 0.3mm, greatly reduces fillet radius, increases the area of contact of axle journal 2 outer wall and needle roller 4, therefore, ensureing that under the prerequisite that area of contact is constant, needle roller 2 can shorten greatly, decreases the processing cost of Hooke's joint.Further, axle journal 2 is set to smooth cylindrical body, has both made the axle sleeve 3 be set on axle journal 2 rotate more flexible, thus has improved Hooke's joint slewing rate, meanwhile, also made Hooke's joint overall processing convenient.
Certainly, this fillet radius also can be other numerical value, as long as this fillet radius is greater than 0.2mm be less than 0.5mm, all in the protection domain of the present embodiment.
Particularly, the center of axle journal 2 end offers blind hole 21, and the back-end central of axle sleeve 3 is provided with outwardly convex body 33, be provided with buffer stopper 6 between the inside of convex body 33 and the end of axle journal 2, buffer stopper 6 two ends are spherical, certainly, also can be other shapes, as taper etc.Buffer stopper 6 is placed in blind hole 21, the end of buffer stopper 6 is stretched out blind hole 21 and is conflicted on the inwall of convex body 33, make axle journal 2 end non-direct contact in axle sleeve 3 inwall, thus prevent the wearing and tearing of Hooke's joint axle journal 2 end in rotation process, increase the working life of Hooke's joint.
Further, oil groove 34 is also arranged with in the rear end of axle sleeve 3, oil groove 34 side is connected with the madial wall of axle sleeve 3 rear end, oil groove 3 contacts with needle roller 4 front end, for lubrication oil, thus axle journal 2 and needle roller 4, friction between axle journal 2 and axle sleeve 3 can be reduced, alleviate the wearing and tearing of the outer wall of the axle journal 2 when axle sleeve 3 rotates, improve the using effect of Hooke's joint.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace or improvement etc., all should be included within protection domain of the present utility model.
