Abstract
The utility model relates to a universal joint and discloses a high-strength oil-injection-free universal joint. A bearing outer ring (4) is assembled on a universal joint pin head (2) of a universal joint pin (1), a dust cover (5) is arranged on the bearing outer ring (4), and a roller pin (3) and a wear-resisting gasket (6) are arranged between the bearing outer ring (4) and the dust cover (5). The wear-resisting gasket is arranged to increase abrasive resistance of the universal joint and prolong service life of the universal joint.
Description
Technical field
The utility model relates to Hooke's joint, has related in particular to a kind of high strength and has exempted from the grease injection Hooke's joint.
Background technique
At present, existing cross axle is because its frictional loss when work is larger, thereby it is excessive to have caused universal joint to wear and tear, the working life of having reduced cardan shaft.
Summary of the invention
The shortcomings such as the utility model is large for Hooke's joint wearing and tearing in the prior art, and working life is short provide a kind of more wear-resisting high strength to exempt from the grease injection Hooke's joint.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals: high strength is exempted from the grease injection Hooke's joint, be equipped with bearing outer ring on the cross-axis head of described cross axle, bearing outer ring is provided with dust-proof cover, is provided with needle roller and wear-resistant gasket between bearing outer ring and the dust-proof cover.
As preferably, described wear-resistant gasket comprises central through bore.
As preferably, described wear-resistant gasket is provided with concave point and circular arc oil groove, and the circular arc oil groove communicates with central through bore.Wear-resistant gasket is made by nylon, and its top is provided with concave point and circular arc oil groove, and two adjacent oil grooves extend to relative both direction radiation respectively, and communicate with central through bore.
The utility model is owing to adopted above technological scheme, and have significant technique effect: the utility model has increased the wear resistance of Hooke's joint by wear-resistant gasket is set, and has prolonged the working life of universal joint.
Description of drawings
Fig. 1 is the utility model embodiment 1 structural representation.
Fig. 2 is the structural representation of wear-resistant gasket among Fig. 1.
The toponym that each number designation refers in the above accompanying drawing is as follows: wherein 1-cross axle, 2-cross-axis head, 3-needle roller, 4-bearing outer ring, 5-dust-proof cover, 6-wear-resistant gasket, 61-circular arc oil groove, 62-concave point, 63-central through bore.
Embodiment
Below in conjunction with accompanying drawing 1 to Fig. 2 and embodiment the utility model is described in further detail:
High strength is exempted from the grease injection Hooke's joint, to shown in Figure 2, is equipped with bearing outer ring 4 on the cross-axis head 2 of described cross axle 1 such as Fig. 1, and bearing outer ring 4 is provided with dust-proof cover 5, is provided with needle roller 3 and wear-resistant gasket 6 between bearing outer ring 4 and the dust-proof cover 5.Wear-resistant gasket 6 comprises central through bore 63.
Wear-resistant gasket 6 is provided with concave point 62 and circular arc oil groove 61, and circular arc oil groove 61 communicates with central through bore 63.Wear-resistant gasket 6 is made by nylon, and its top is provided with concave point 62 and circular arc oil groove 61, and two adjacent oil grooves extend to relative both direction radiation respectively, and communicate with central through bore 63.By circular arc oil groove 61 is set, can allow lubricant oil flow into central through bore 63 along oil groove, play the skidding effect.
In a word, the above only is preferred embodiment of the present utility model, and all equalizations of doing according to the utility model claim change and modify, and all should belong to the covering scope of the utility model patent.
