Description
Technical field
The utility model relates to a kind of universal joint assembly, especially relates to a kind of stealthy oil channel type 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 (notice of authorization number: CN 2464984Y), it comprise cross axle and be arranged on needle roller around of cross axle spindle nose and put with needle roller outside outer ring, 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 inner side 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; Between internal face and needle roller end face ring, be tiltedly provided with annular grinding undercut, and needle roller end face ring is in the same plane with the cross axle spindle nose end face that is placed in needle roller inner side, the inner side of needle roller end face ring is provided with 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 ° of-55 ° of angles, and its degree of depth is 0.25-0.6mm, and end is the circular arc ring that radius is 0.3-5.Omm.But the oil duct of this universal joint is all criss-cross, and cross axle intermediate portion must be solid, the volume of transmission shaft is just larger like this, has increased destabilizing factor.
Model utility content
The utility model is to provide a kind of stealthy oil channel type universal joint assembly, it is mainly that the oil duct of the existing universal joint of solution prior art is all criss-cross, cross axle intermediate portion must be solid, the volume of transmission shaft is just larger like this, increased the technical problem of destabilizing factor etc.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
Stealthy oil channel type universal joint assembly of the present utility model, comprise cross axle, on four axles of described cross axle, be all socketed with an axle bowl, between axle bowl and axle, be provided with needle roller, on four axle bowls, be all connected with an oil nozzle, the centre of cross axle is provided with circular through hole, and the surrounding of through hole is distributed with annular oil duct, and oil duct is communicated with oil nozzle.Hollow out in the middle of the utility model adopts, stealthy oil channel type design, transmission shaft can be abundant like this
Space in the middle of interests, makes product tightr, and space availability ratio is higher.Oil duct is annular, and therefore it can make 4 oil nozzles all be communicated with, and therefore, no matter from which oil nozzle oiling, fluid can enter into each position of universal joint assembly.Ring shaped oil passage is hidden in the periphery of universal joint assembly through hole, and structure is comparatively compact.
As preferably, the internal surface of described axle bowl is provided with multiple tracks salient point, between salient point and needle roller for point contacts.Reduce like this wearing and tearing of inside, outer ring with needle roller, ensured that again needle roller can be positioned in outer ring simultaneously.
As preferably, the axle journal place of described cross axle is provided with oil sealing.Can prevent that like this fluid from spilling from the gap of axle bowl and cross axle.
As preferably, described annular oil duct is provided with oiling section, and the width of oiling section is greater than the width of oil duct.Oiling section volume is larger, therefore can station part fluid, and owing to removing, the oil duct width of oiling section part is narrower, and therefore the pressure of this part oil duct is larger, and it can be pressed onto oiling section place by unnecessary fluid and preserve.
Therefore, the utility model is offered through hole by the middle part at cross axle, and in bore periphery, annular oil duct is set, make transmission shaft can make full use of middle space, make product tightr, space availability ratio is higher, and the wear resistance of whole universal joint assembly is higher, sealability is better, simple and reasonable for structure.
Brief description of the drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model.
Component, position and numbering in figure: cross axle 1, axle bowl 2, needle roller 3, oil nozzle 4, through hole 5, oil duct 6, salient point 7, oil sealing 8, oiling section 9.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: the stealthy oil channel type universal joint assembly of this example, as Fig. 1, comprise cross axle 1, on four axles of cross axle, be all socketed with an axle bowl 2, between axle bowl and axle, be provided with on 3, four axle bowls of needle roller and be all connected with an oil nozzle 4, the centre of cross axle is provided with circular through hole 5, the surrounding of through hole is distributed with annular oil duct 6, and oil duct is communicated with oil nozzle.The internal surface of axle bowl is provided with multiple tracks salient point 7, is that point contacts between salient point and needle roller.The axle journal place of cross axle is provided with oil sealing 8.The oil duct of annular is provided with oiling section 9, and the width of oiling section is greater than the width of oil duct.
When use, the utility model is packed in the machinery of required use.
The foregoing is only specific embodiment of the utility model, but structure characteristic of the present utility model is not limited to this, any those skilled in the art is in field of the present utility model, and the variation of doing or modification are all encompassed among the scope of the claims of the present utility model.
