Description
Technical field
The utility model relates to a kind of universal joint assembly, especially relates to a kind of iron sheet bearing universal joint assembly.
Background technique
Universal-joint cross trunnion of the prior art, generally all forms by middle axis body and with the arm that middle axis body links into an integrated entity.Chinese patent discloses a kind of high-strength universal joint (Authorization Notice No.: CN 2464984Y), it comprises cross axle and the needle roller that is arranged on around cross axle spindle nose and putting and the outer ring outside needle roller, the end of outer ring is provided with packing holder, and described packing holder is provided with seal ring skeleton and seal placed on it; And the inner side of described seal is provided with tilting outer lip and the inside middle lip of lip and inner lip successively, three lips contact with the axle journal of cross axle; The grinding undercut of annular is tiltedly provided with between internal face and needle roller end face ring, and needle roller end face ring is in the same plane with the cross axle spindle nose end face be placed in inside needle roller, the inner side of needle roller end face ring is provided with pad chamber, it is built-in with fiber nylon Composition spacer, and the exterior edge face of Composition spacer flushes substantially with described needle roller end face ring; The center line of grinding undercut and bottom plane, outer ring are 35 ° ~ 55 ° angles, and its degree of depth is 0.25 ~ 0.6mm, the circular arc ring of to be radius be in end 0.3 ~ 5.Omm.But the trunnion journal of this universal joint is comparatively thin, and intensity is more weak, tired and life test is all poor, in addition because dust-proof mechanism is single, cause dust-proof effect poor.
Model utility content
The utility model is to provide a kind of iron sheet bearing universal joint assembly, its trunnion journal mainly solving the universal joint existing for prior art is comparatively thin, and intensity is more weak, tired and life test is all poor, in addition because dust-proof mechanism is single, cause the technical problem of the poor grade of dust-proof effect.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
Iron sheet bearing universal joint assembly of the present utility model, comprise cross axle, described cross axle is provided with oil nozzle, the axis body of cross axle is socketed with iron sheet axle sleeve, needle roller is provided with between iron sheet axle sleeve and axis body, the axle journal place of axis body is provided with shafting oil envelope, and the outer surface of iron sheet axle sleeve is provided with locating slot, and the outer end of shafting oil envelope extends to the outer surface of iron sheet axle sleeve and withstands in locating slot.Offer locating slot at the outer surface of iron sheet axle sleeve, shafting oil is sealed and can be positioned in the outer surface of iron sheet axle sleeve, prevent whole universal joint in use, after the displacement of shafting oil envelope, it is difficult to play dust-proof effect, and does not keep section to be the shape of arc.Former universal joint assembly uses conventional cold-heading axle sleeve, and the utility model is with DC04 iron sheet axle sleeve, and make trunnion journal overstriking, such intensity increases, and tired and life test has enhancing.The Sealing of shafting oil envelope is made up of acrylate adhesive, and it forms a grease proofing dust-proof cover, covers the gap between cross axle axis body and axle sleeve.
As preferably, metal frame is provided with between the inner of described iron sheet axle sleeve and cross axle axis body, metal frame is provided with Sealing, three sealing lip contacts of Sealing are on the axis body of cross axle, the middle part of shafting oil envelope is connected with supporting element, and supporting element passes the gap-contact of axis body and iron sheet axle sleeve to Sealing.Cross axle shoulder adds dust-proof cover structure, greatly improves dust-proof effect.And shafting oil envelope by supports support, is made shafting oil seal and can remain bandy shape, thus ensure that dust-proof effect on Sealing.
As preferably, the inner bottom surface edge of described iron sheet axle sleeve is provided with oiling groove, the edge of needle roller contact oiling groove.Oiling groove on the one hand can indwelling lubricant oil, and to needle roller with lubrication, it can reduce the area of contact of needle roller and axle sleeve inner bottom surface on the other hand, thus prevents from wearing and tearing.
As preferably, in the middle part of the inner bottom surface of described iron sheet axle sleeve, be provided with cavity.The area of contact of axis body and iron sheet axle sleeve bottom surface can be reduced by cavity, decrease the wearing and tearing of axis body, make working life longer.
Therefore, cross axle overstriking of the present utility model axle journal, add intensity, and sealed by shafting oil, cover the gap between axis body and iron sheet axle sleeve, prevent dust to invade, utilize the shape of supporting element retainer shaft oil sealing, and also add the dust guard with sealing lip in the inside of iron sheet axle sleeve, further enhance dust-proof effect, simple and reasonable for structure.
