For solving the easily wearing and tearing in the course of the work of the dirt-proof boot on existing driving-shaft assembly in background technique, the problem that working life is short, the utility model provides a kind of dirt-proof boot rotatable driving-shaft assembly.
The technical solution of the utility model is: the rotatable driving-shaft assembly of a kind of dirt-proof boot, comprise transmission shaft, fixed end universal joint, fixed end seal closure and dust-proof cover, described dust-proof cover comprises dust-proof cover cover body, one end of described dust-proof cover cover body is serrated end, the other end is open end, in described dust-proof cover cover body, be provided with bearing, between the end face of described bearing and dust-proof cover cover body serrated end, be provided with bearing seal cover, described bearing comprises and bearing inner race, the needle roller of transmission shaft interference fit and the bearing outer ring being connected with dust-proof cover cover body inwall.
As a kind of improvement of the present utility model, described bearing outer ring is connected with dust-proof cover cover body by the connecting sleeve that is bumped into dust-proof cover cover body inwall.
As further improvement of the utility model, the outer wall of described dust-proof cover cover body serrated end is provided with clip in position of bearings.
As further improvement of the utility model, in described dust-proof cover cover body, be provided with containing groove, described bearing seal is arranged with in containing groove.
As further improvement of the utility model, the outer wall of described dust-proof cover cover body open end is provided with flange, and described dust-proof cover cover body open end outwards folds edge, and the horizontal position of described flange bottom is higher than the horizontal position of bottom surface, edge.
As further improvement of the utility model, described flange and dust-proof cover cover body are integral type structure.
The beneficial effects of the utility model are; bearing and bearing seal cover are increased; avoid between dirt-proof boot and transmission shaft, producing wearing and tearing and gap in the time that transmission shaft rotates; prevent that dust and foreign matter from entering in transmission part; damage driving parts; the simultaneously design of bearing seal cover also can avoid lubricating grease in dirt-proof boot to reveal playing under the prerequisite that further sealing avoids dust to enter, and plays protection bearing flexible rotating and the effect to transmission part anti-rust and lubrication, improves its working life.
