Abstract
The utility model relates to a universal joint, in particular to a dust proof cover for universal joint, which comprises a dust proof cover body and a lip opening. The lip opening is distributed at the inner face of the outer wall of the cover body at equal width. The utility model solves the problem existing in the prior art that the originally designed size is hard to recover after installation which is not beneficial for installing and operating. The utility model has the advantages of reasonable design, simple structure and being beneficial for installation, and the originally designed size is easy to recover after installation.
Description
Technical field
The utility model relates to a kind of universal joint, particularly a kind of universal joint dust-proof cover.
Technical background
Universal joint adopts oil sealing to add dust-proof cover usually and plays sealing, dustproof effect, and most nylon, the plastic or other material of adopting of dust-proof cover are made.But dust-proof cover of the prior art only depends on the elasticity of material to guarantee that dust-proof cover follows the cooperation of bearing outer ring, is difficult to recover the original design size after existing installation, is unfavorable for problems such as fitting operation.
Summary of the invention
The utility model is difficult to recover the original design size after having solved the installation that prior art exists, and is unfavorable for problems such as fitting operation, provides a kind of reasonable in design, simple in structure, is beneficial to installation, and the universal joint dust-proof cover that the back is recovered the original design size easily is installed.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: comprise dustproof cover body and lip, the wide cover body outer wall inner face that is distributed in of described lip.Wherein, the circumferential width of the spacing of lip and lip and lip is suitable; Lip adopts nylon, plastic or other material to make, make lip can form elasticity, lip is divided into some equal portions and is distributed in cover body outer wall inner face, is beneficial to the installation of dust-proof cover, can make the dust-proof cover after the installation recover original size, reach the effect of the fitted seal that is connected with bearing of expection.
As preferably, described lip is the 8-16 equal portions.
As preferably, the angle of described outer wall inner face and dust cover centers line is 3 °-20 °.Wherein, the surface of the angle of outer wall inner face and dust cover centers line is used for the elastic packing with bearing oral area conical surface position, plays buffer action dustproof, waterproof.
As preferably, described lip inner face diameter is greater than the outside diameter of cover body inwall; The thickness of described lip is 2-3 times of outer wall thickness.Wherein, the sidepiece of lip can be designed to certain gradient, to increase the intensity of lip.
Therefore, the utlity model has reasonable in designly, simple in structure, be beneficial to installation, the back is installed recovers characteristics such as original design size easily.Wherein, the circumferential width of the spacing of lip and lip and lip is suitable; Lip adopts nylon, plastic or other material to make, make lip can form elasticity, lip is divided into some equal portions and is distributed in cover body outer wall inner face, is beneficial to the installation of dust-proof cover, can make the dust-proof cover after the installation recover original size, reach the effect of the fitted seal that is connected with bearing of expection.Wherein, the surface of the angle of outer wall inner face and dust cover centers line is used for the elastic packing with bearing oral area conical surface position, plays buffer action dustproof, waterproof.Wherein, the sidepiece of lip can be designed to certain gradient, to increase the intensity of lip.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model;
