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, and the inner side of the dustproof cover is clung to the axle head of the cross axle. A clamping ring is arranged on the upper side of the outer side of the dustproof cover, and the clamping ring is clamped on a nose end which is outwards extended by a support element. 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; meanwhile, the dustproof cover is clamped on the nose end, which increases the enlarging space of an axle diameter.
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 that spindle nose at cross axle is nested with oil sealing, 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 band dust-proof cover 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 with dust-proof cover, 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 dust-proof cover outside is provided with collar, and collar is stuck on the outward extending nose of supporting member of seal ring.
As preferably, dust-proof cover is made by nylon, and dust-proof cover is along circumferentially being evenly equipped with recess.
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 along circumferentially being evenly equipped with recess, makes dust-proof cover cover body good springiness, cooperates resistance little, has further facilitated the assembling of dust-proof cover.Simultaneously, dust-proof cover is stuck on the nose, also can increase the space that the diameter of axle enlarges, and is useful to the intensity that strengthens cross axle.

Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is made a detailed explanation.
A kind of Hooke's joint with dust-proof cover as shown in Figure 1 and Figure 2 is made up of cross axle 1, bearing housing 5, thrust washer 6, needle roller 3 and seal ring 2 and dust-proof cover 9.Seal ring 2 is arranged in the bearing housing 5, is supported by supporting element 7.Dust-proof cover 9 is arranged on bearing housing 5 opening ends.The spindle nose 4 of cross axle is close in dust-proof cover 9 inboards, and its top, outside is provided with collar 8.Simultaneously, stretch out at the supporting member 7 of seal ring 2 and be provided with a nose 10.Collar 8 is stuck on the nose 10.
In addition, between needle roller 3 and seal ring 2, be provided with the elastic washer 11 that turns in the plane.The cross section of elastic washer 11 tilts to be certain angle from inside to outside.
As Fig. 4, shown in Figure 5, dust-proof cover 9 is made by nylon, along circumferentially being evenly equipped with recess 12.
As shown in Figure 6, thrust washer 6 is made by nylon, and its top is provided with circular arc oil groove 13, and adjacent two oil grooves 13 extend to relative both direction radiation respectively.
During assembling, the collar 8 of dust-proof cover 9 is assemblied on the nose 10 of supporting member 7, in the axis hole with the dust-proof cover 9 of packing into of cross axle, gets final product then.
