Description
Technical field
The utility model relates to constant velocity universal joint field, particularly a kind of dust-proof cover of constant velocity universal joint.
Background technique
The dust-proof cover of existing constant velocity universal joint, generally comprise cover body, described cover body one end is connecting end, the other end is positioning end, the connecting end of described cover body is set on the housing of universal joint, the positioning end of cover body is set in the rotating shaft of universal joint, the positioning end of cover body and rotating shaft interference fit, the housing of universal joint is provided with draw-in groove, when installation, need to rotate dust-proof cover connect end snap in draw-in groove, but, the dust-proof cover of this structure, due to positioning end and the rotating shaft interference fit of cover body, inconvenience in the time rotating, easily make dust-proof cover distortion, and, when work, under the drive of rotating shaft compression and rotation, also easily cause dust-proof cover to produce distortion, produce internal stress, make the life-span of dust-proof cover short.
Summary of the invention
The purpose of this utility model: in order to overcome the defect of prior art, the utility model provides a kind of dust-proof cover of constant velocity universal joint, the installation of energy convenient dust-proofing cover, and, when work, reduce the generation of internal stress, extend the life-span.
The technical solution of the utility model: a kind of dust-proof cover of constant velocity universal joint, include cover body, described cover body one end is connecting end, the other end is positioning end, it is characterized in that: in described cover body, be positioned at positioning end one side and be provided with bearing.
Adopt technique scheme, by the bearing arranging, when installation, bearing housing is located in the rotating shaft of universal joint, like this to rotate dust-proof cover very convenient when connecting end and snapping in draw-in groove on cardan joint housing, and, when work, can reduce the generation of dust-proof cover internal stress, extend the life-span.
Further setting of the present utility model: the outboard end that is positioned at bearing in described cover body is provided with seal ring.
Adopt above-mentioned further setting, the seal ring of setting, can prevent that the lubricant oil of bearing, universal joint inside from leaking, thereby ensure its stable work in work.
Further setting more of the present utility model: described bearing includes outer ring, inner ring, between described outer ring, inner ring, be provided with rolling element, described interior ring cross-section is the setting of " U " font, described outer ring cross-section is down the setting of " U " font, the outboard end of described inner ring extends to outside cover body, the end face of the cover body positioning end one side circular orientation limit that extended internally, described seal ring is between the end face of the outside of circular orientation limit and outer ring.
Adopt above-mentioned further setting again, the bearing set-up mode of this structure, can make its location firm, and inner rolling element can not come off, the circular orientation limit of setting, and positioning seal ring well, ensures that its sealing is reliable.
Further setting more of the present utility model: described seal ring is provided with two sealing lips, and the outer ring face of described sealing lip and inner ring is conflicted.
Adopt above-mentioned further setting again, two sealing lips of setting, make the sealing performance of seal ring good.
Brief description of the drawings
Fig. 1 is the utility model specific embodiment and cardan joint housing, rotating shaft connecting structure schematic diagram;
Fig. 2 is I part partial enlarged drawing in Fig. 1;
Fig. 3 is the utility model specific embodiment middle (center) bearing structural representation.
Embodiment
As Figure 1-3, a kind of dust-proof cover of constant velocity universal joint, includes cover body 1, described cover body 1 one end is connecting end 11, the other end is positioning end 12, is positioned at positioning end 12 1 sides and is provided with bearing 2 in described cover body 1, and the outboard end that is positioned at bearing 2 in described cover body 1 is provided with seal ring 3.By the bearing 2 arranging, when installation, bearing 2 is set in the rotating shaft 5 of universal joint, connect end 11 to snap in draw-in groove 41 on cardan joint housing 4 very convenient when interior rotating dust-proof cover like this, and, when work, can reduce the generation of dust-proof cover internal stress, extend the life-span; The seal ring 3 arranging, can prevent that the lubricant oil of bearing 2, universal joint inside from leaking, thereby ensure its stable work in work.
In the utility model specific embodiment, described bearing 2 includes outer ring 21, inner ring 22, between described outer ring 21, inner ring 22, be provided with needle roller 23, described inner ring 22 cross sections are the setting of " U " font, described 21 cross sections, outer ring are down the setting of " U " font, the outboard end of described inner ring 22 extends to outside cover body 1, the end face of the cover body 1 positioning end 12 1 sides circular orientation limit 13 that extended internally, and described seal ring 3 is between circular orientation limit 13 and the outside end face of outer ring 21.Bearing 2 set-up modes of this structure, can make its location firm, and inner needle roller 23 can not come off, the circular orientation limit 13 of setting, and positioning seal ring 3 well, ensures that its sealing is reliable.
In the utility model specific embodiment, described seal ring 3 is provided with two sealing lips 31, and described sealing lip 31 is conflicted with the outer ring face of inner ring 22.Two sealing lips 31 that arrange, make the sealing performance of seal ring 3 good, the dust-proof cover of this structure, in the time of the inside and outside air pressure difference of dust-proof cover, sealing lip 31 produces micro-deformation, thereby gas can, between sealing lip 31 and inner ring 22, be circulated between needle roller 23, ensure that inside and outside air pressure is identical, and then can prevent dust-proof cover distortion.
