According to an aspect of the present utility model, the nonabradable high lubricative axle sleeve providing, comprises inner sleeve, overcoat and the side direction fixing device of coaxial setting;
Wherein, described outer sleeve around be arranged on described inner sleeve outside and described outside be set on one end of described inner sleeve; Described inner sleeve is provided with axis hole; Described side direction fixing device is arranged in described and puts, along the radially extension of described inner sleeve.
Preferably, described inner sleeve length is in the axial direction greater than described overcoat length in the axial direction.
Preferably in, also comprise the first through hole, the quantity of described the first through hole is a plurality of, a plurality of described the first through holes are evenly arranged on described outer putting, and along the axial direction of described overcoat, run through described overcoat.
Preferably, also comprise the second through hole, described the second through hole is arranged in described and puts, and along the axial direction of described inner sleeve, runs through described inner sleeve.
Preferably, the quantity of described the second through hole is a plurality of, and a plurality of described the second through holes distribute axisymmetricly along a wherein bisector of described inner sleeve.
Preferably, also comprise side direction fixing device, described side direction fixing device is arranged in described and puts, along the radially extension of described inner sleeve.Described side direction fixing device is extended from the inner side of inner sleeve described in the lateral of described inner sleeve.
Preferably, the quantity of described side direction fixing device is two, and two described side direction fixing devices distribute axisymmetricly along described bisector.
Preferably, in the axial direction, a side of described inner sleeve is concordant with a side of described overcoat, and the opposite side of described inner sleeve and the opposite side of described overcoat are step-like.
Compared with prior art, the utlity model has following beneficial effect:
In the utility model, interior putting, be provided with side direction fixing device, on the hole wall of axis hole, be provided with groove, improved lubrication effect between axle sleeve and rotating shaft, reduced the wearing and tearing between axle sleeve and rotating shaft, reduced noise.
