By adopting technique scheme, bearing inner ring outer surface is provided with some projections, dust cover is provided with holding cavity and holding cavity is provided with block, between block, form gap, in the time of dress dust cover, the gap alignment projection between block is buckled in dust cover on bearing inner ring like this, rotate again dust cover, elastic clamping block on bearing inner ring side is extruded, make dust cover and bearing inner ring rotary fastening, projection and block are inconsistent, realize the axial restraint of dust cover, and fixture block is stuck in the draw-in groove on dust cover, realize so again the circumferentially fixing of dust cover, stability maintenance is good, only need promote push rod at dismounting dust cover, make fixture block shift out draw-in groove, rotate so again dust cover, just can take out dust cover, simple and convenient quick, nor understand the situation appearance that dismounting is not got off with worrying to get rusty.
The utility model is further set to: described dust cover internal surface is provided with some oil storages portion, and a side of the relative rolling element of described oil storage portion is equipped with oil outlet.
By adopting technique scheme, because dust cover is fixedly connected with bearing inner ring, in the time of bearing working, bearing inner ring drives dust cover, lubricant oil in oil storage portion can throw away from oil outlet under the effect of centrifugal force like this, rolling element is carried out well lubricating comprehensively, extend the working life of bearing.
The utility model is further set to: the two ends of described push rod are equipped with stop part, and described stop part size is greater than groove size.
By adopting technique scheme, push rod two ends stop part size is greater than groove size, can effectively ensure that like this push rod can not drop out and affect using effect from groove, push rod always in groove, faster and more convenient operation.
The utility model is further set to: described dust cover is made up of aluminum alloy material.
By adopting technique scheme, not only quality is light for aluminum alloy, intensity is high need not damage, and has good corrosion resistance and thermal conductivity, and durable in use, the heat that can leave fast in bearing, works bearing normally, extends its working life.
