Further, a bushing is arranged between the sleeve and the rotating rod.
Furthermore, a plurality of through holes are arranged on the circumferential surface of the lining, and a lubricating component is embedded in each through hole.
Further, the lubricating component is a cylinder made of any one of molybdenum disulfide or graphite.
Furthermore, a screw hole is vertically formed in the end part of the rotating rod, the lower end of the screw hole is communicated with the connecting groove, a screw rod is connected in the screw hole in an engaged mode, and a linear groove is formed in the upper end of the screw rod; the lower end of the screw rod penetrates into the connecting groove, the limiting groove is formed in the connecting key, and when the connecting key is inserted into the connecting groove, the lower end of the screw rod is meshed and screwed into the limiting groove.
Further, a gasket is arranged on the outer side of the bushing.
The utility model has the advantages that:
the utility model provides a omnipotent movable shaft sleeve of low friction has simple structure, multiple sealed better sealed effect that plays, can not lead to frictional force too big because of multiple sealing simultaneously again, the advantage that the temperature rise uprises relatively, the bond linkage is connected with interference fit's mode with the spread groove, the other end of changing the head is provided with the external diameter recess that is used for the connecting axle, different change heads have not unidimensional external diameter recess, change different change heads, just can connect the axle of different diameters, realize a tractor serves several purposes's effect, only need different change heads, need not dismantle change bearing frame isotructure, high durability and convenient use. The lubricating component can wear to form fine wear particles, the surface of the rotating rod is full of the fine wear particles, a lubricating film is formed at the moment, the lubricating effect is improved, the wear is reduced rapidly, and the long-time use is guaranteed. The outside of the bushing is provided with a gasket for limiting and sealing.
