Abstract
The utility model relates to universal joint assemblies and particularly relates to a high-temperature-resistant, wear-resistant and maintenance-free universal joint assembly for a transmission shaft of a heavy truck. The universal joint assembly is mainly used for solving the technical problems in the prior art that a universal joint is short in service life, needs frequent replacement, is poor in sealing performance and cannot be applied to the transmission shaft of the heavy truck, and the like caused due to the fact that rolling needles of the universal joint are easily worn and the universal joint is difficult to withstand high temperature. The universal joint assembly comprises a cross shaft body (1) and is characterized in that four shaft sleeves (2) are respectively sleeved on four shaft bodies of the cross shaft body (1), double-row rolling needles (3) are arranged in the shaft sleeves, steps are arranged at the root part of the cross shaft body, outer sealing members (4) and inner sealing members (5) are respectively arranged at the two ends of the steps, and retaining rings (6) are arranged in the shaft sleeves and are located between the outer sealing members and the inner sealing members.
Description
Technical field
The utility model relates to a kind of universal joint assembly, especially relates to a kind of high temperature resistant, wear-resisting, non-maintaining type and heavily blocks the shaft universal-joint assembly.
Background technique
Universal-joint cross trunnion of the prior art general all forms by middle axis body and with arm that middle axis body links into an integrated entity.Chinese patent discloses a kind of high-strength universal 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, is provided with seal ring skeleton and seal placed on it on described packing holder; And the inboard of described seal is provided with tilting outer lip and inside middle lip and the inner lip of lip successively, and three lips contact with the axle journal of cross axle; Tiltedly be provided with the grinding undercut of annular between internal face and needle roller end face ring, and the needle roller end face ring is in the same plane with the cross axle spindle nose end face that is placed in the needle roller inboard, the inboard of needle roller end face ring is provided with the pad chamber, it is built-in with glass 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, and the end is the circular arc ring that radius is 0.3～5.Omm.But the needle roller of this universal joint is more easy to wear, is difficult for bearing high temperature, thereby causes the working life of universal joint shorter, need often to change, and sealability is relatively poor, can't use in the transmission shaft of heavy truck.
The model utility content
The utility model technical issues that need to address are to provide a kind of high temperature resistant, wear-resisting, non-maintaining type and heavily block the shaft universal-joint assembly, it is mainly that to solve the needle roller of the existing universal joint of prior art more easy to wear, be difficult for bearing high temperature, thereby cause the working life of universal joint shorter, need often to change, and sealability is relatively poor, can't use in the medium technical problem of the transmission shaft of heavy truck.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
High temperature resistant, wear-resisting, non-maintaining type of the present utility model heavily blocks the shaft universal-joint assembly, comprise the cross axle body, all be socketed with axle sleeve on four axis bodies of described cross axle body, be provided with double needle roller in axle sleeve, the root of cross axle body is provided with a step, the two ends of step are respectively equipped with outside seal may, inner seal liner, are provided with back-up ring in axle sleeve, and back-up ring is between outside seal may and inner seal liner.Step two ends at the cross axle body arrange respectively outside seal may, inner seal liner, make sealing effect better, and needle roller is not easy to wear, can be high temperature resistant, and non-maintaining.
As preferably, the section of described outside seal may is " L " type, and it coats the end face of axle sleeve.Outside seal may can prevent that dust from entering into axle sleeve inside.
As preferably, the inner bottom surface of described axle sleeve is provided with oil groove.Fluid can be marked with in oil groove, lubricated effect can be played.
As preferably, be provided with pad between the inner bottom surface of described needle roller and axle sleeve.Pad can prevent that needle roller from directly contacting iron sheet axle sleeve bottom surface, has avoided the wearing and tearing of needle roller, has extended the working life of universal joint bearing.
Therefore, universal joint of the present utility model adopts two seals, makes needle roller more not easy to wear, can bear high temperature, and is non-maintaining, makes the working life of universal joint longer, can use in the transmission shaft of heavy truck, simple and reasonable for structure.
