Abstract
The utility model relates to a cross axle universal joint, in particular to a cross axle universal joint whose dustproof cover is improved. The cross axle universal joint whose dustproof cover is improved is composed of a cross axle, a bearing sleeve, a thrust washer, a roller pin, a sealed ring, and a dustproof cover. The dustproof cover is arranged on the opening end of the bearing sleeve. The inner side of the dustproof cover is clung to the axle head of the cross axle, and a clamping ring is arranged on the upper side of the outer side of the dustproof cover. The clamping ring is clamped a clamping ring groove on the inner side of the opening end portion of the bearing sleeve. The cross axle universal joint whose dustproof cover is improved has good dustproof effect, reasonable structure, convenient manufacture and installation, and neat and beautiful appearance. The dustproof cover is made by adopting nylon, and the circumferential direction of the dustproof cover is provided with notches. The cover body of the dustproof cover has good elasticity and small matching resistance, which is further convenient for the dustproof cover to be assembled.
Description
Technical field
The utility model relates to a kind of Hooke's joint, relates in particular to a kind of Hooke's joint that improves dust-proof cover.
Background technique
The seal arrangement of existing Hooke's joint, usually all be in the bearing housing of cross axle, oil sealing to be set, and shelter-clad is set outside scraper ring, there is bigger gap in this seal arrangement, Hooke's joint when in use, dust and muddy water are easy to enter in the bearing, to the performance of Hooke's joint with cause very big influence working life.Also there are some Hooke's joints to be provided with dust-proof cover, but complex structure, the installation of dust-proof cover is extremely inconvenient.The user in use, the installation of dust-proof cover is not quick detachable, does not satisfy the requirement of continuous disposable assembling.
Summary of the invention
In order to solve above-mentioned technical barrier, the purpose of this utility model provides a kind of Hooke's joint of simple in structure, easy for installation, good dustproof effect.
In order to realize above-mentioned purpose, the utility model has adopted following technological scheme: a kind of Hooke's joint, form by cross axle, bearing housing, thrust washer, needle roller and seal ring and dust-proof cover, dust-proof cover is arranged on the cage openings end, the spindle nose of cross axle is close in the dust-proof cover inboard, top, the outside is provided with snap ring, and snap ring is stuck on the annular groove of inboard, cage openings end.
As preferably, dust-proof cover is made by nylon, and dust-proof cover is along circumferentially being evenly equipped with recess.The outside of the snap ring of dust-proof cover is provided with the inclined-plane, and perhaps the outside of snap ring is provided with arc surface.
As preferably, between needle roller and seal ring, be provided with the elastic washer that turns in the plane.
As preferably, thrust washer is provided with the circular arc oil groove, and adjacent two oil grooves extend to relative both direction radiation respectively.
The utility model has been owing to adopted above technological scheme, and the good dustproof effect of dust-proof cover is rational in infrastructure, make, easy to assembly, and profile and Hooke's joint coupling, clean and tidy, attractive in appearance.Dust-proof cover adopts nylon to make, and is circumferentially with recess at it, makes dust-proof cover cover body good springiness, cooperates resistance little, has further facilitated the assembling of dust-proof cover.
