Adopt above-mentioned scheme, inlay the universal roller bearing and inlay the dress in circular recess, the external diameter of universal roller bearing and the internal diameter adaptation of circular recess for universal roller bearing is difficult for the slope of swaying in circular recess, can be convenient for the ejector pin top better and push away the axostylus axostyle, the rethread chuck supports universal roller bearing's outer lane and inner circle, can make the ejector pin push away the axostylus axostyle in exert a reverse acting force to universal roller bearing through the chuck, thereby can make things convenient for universal roller bearing and axostylus axostyle to realize. Simple structure and convenient processing and implementation.
As a further setting of the utility model, the chuck comprises two arc splice pieces concatenation, is provided with the slot and the inserted block that are used for the location of pegging graft between the concatenation face of two arc splice pieces, the slot with the big or small adaptation of inserted block shape.
By adopting the scheme, the actual shaft rod is relatively long, the chuck is formed by splicing the two arc-shaped splicing blocks, the universal roller bearing can be firstly installed in the bearing sleeve, and the bearing is axially limited by the splicing chuck. The universal roller bearing is more conveniently arranged in the bearing sleeve, and the chuck can be conveniently and detachably arranged on the end face of the bearing sleeve.
As the utility model discloses a further setting, the chuck passes through fastening bolt can dismantle fixed the setting and be in on the one end terminal surface of bearing housing.
By adopting the scheme, the structure is simple, the dismounting is convenient, and the implementation is easy.
As a further setting of the utility model, the position that the other end terminal surface of bearing housing corresponds the screw hole outwards extends and is provided with the connecting block, the screw hole extends along connecting block length direction.
By adopting the scheme, the connecting block is arranged by extension, so that the bolt joint part of the ejector rod is enlarged, the strength of bolt joint is improved, and the ejector rod is convenient to push the shaft rod to be separated from the bearing when the bearing sleeve has a certain protection effect.
As a further arrangement of the utility model, the ejector pin is provided with the top towards the one end of bearing housing, the top is conical.
By adopting the scheme, the shaft lever is pushed through the conical ejector head, the pressure is increased, the pushing effect of the ejector rod is improved, and the drawing efficiency of the shaft lever and the bearing is improved.
The present invention will be further described with reference to the accompanying drawings.
