Description
Technical field
The utility model relates to a kind of universal joint assembly, especially relates to a kind of oil-filling type universal joint assembly fast.
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 ° of-55 ° of 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 this universal joint only has a pouring orifice, and the oiling time is long, oil injecting speed is slow, and easy oiling is not in place, and product is easily burnt, and not wear-resisting, and sealability is poor, and working life is shorter.
Model utility content
The utility model is to provide a kind of oil-filling type universal joint assembly fast, its universal joint mainly solved existing for prior art only has a pouring orifice, the oiling time is long, oil injecting speed is slow, easy oiling is not in place, and product is easily burnt, and not wear-resisting, sealability is poor, working life shorter grade technical problem.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
Quick oil-filling type universal joint assembly of the present utility model, comprise cross axle, four axles of described cross axle are all socketed with an outer ring, between outer ring and axle, are provided with needle roller, a pair outer ring that cross axle is wherein symmetrical is connected with oil nozzle, and the centre of cross axle is also connected with an oil nozzle.The utility model adopts three oil nozzles designs, makes different directions and position can oiling, can effectively prevent product from burning.
As preferably, the internal surface of described outer ring is provided with multiple tracks salient point, is point cantact between salient point and needle roller.Which reduce inside, outer ring and the wearing and tearing of needle roller, in turn ensure that needle roller can be positioned in outer ring simultaneously.
As preferably, the end of described needle roller is provided with the metal frame of L shape, and metal frame is provided with oil sealing, and oil sealing has the sealing lip that 3 can contact trunnion journal part, the end face of one of them sealing lip is the plane being close to axle journal, and the section of two other sealing lip is zigzag fashion.Exterior edge face is the plane that the sealing lip of plane can seal trunnion journal place, and two other zigzag sealing lip can the cambered surface at corresponding trunnion journal place, thus sealing effect is better.
As preferably, in the middle of the bottom surface of described outer ring and the cylindrical of bottom surface all have oiling groove, leave gap between the axis body end face of cross axle and oiling groove.Lubricating grease can be left in the bottom surface of inner ring and cylindrical place, thus ensure that the operation of universal joint assembly is smooth and easy.
Therefore, the utility model by arranging 3 oil nozzles on two axle sleeves of symmetry and in the middle of cross axle, make different directions and position can oiling, can effectively prevent product from burning, and utilize the oil sealing of many sealing lips, make sealing better, improve the wear resistance of whole universal joint assembly, simple and reasonable for structure.
