Design effectively reduces dust and fallen into axle sleeve, and the oil groove of more settings arranged in parallel, it is ensured that lubricant effect, will not be because of
Wherein an oil groove, which blocks, causes whole boss failure, hence it is evident that extends service life.
Brief description of the drawings
Technical solution of the present invention is described further below in conjunction with the accompanying drawings：
Accompanying drawing 1 is the structural representation of the present invention；
Accompanying drawing 2 is the front view of the present invention；
Accompanying drawing 3 be in accompanying drawing 2 A-A to sectional view；
Accompanying drawing 4 is the structural representation of oilhole lid in the present invention.
Embodiment
Illustrate the present invention below in conjunction with the accompanying drawings.
A kind of axle sleeve of the present invention, as shown in accompanying drawing 1-4, includes the axle sleeve main body 1 of the tubular in both ends open；The axle
Cover and offer several oil grooves 2 on the inwall of main body 1；Several described oil grooves 2 equally helical form and the not phase that is parallel to each other
Hand over；Several oil filler points 3 are offered in the front end side wall of the axle sleeve main body 1；In the present embodiment, the oil groove 2 has 3, phase
The oil filler point 3 answered also has 3；The oil filler point 3 is arranged in a ring in the side wall of axle sleeve main body 1；The quantity of the oil filler point 3
It is equal with the quantity of oil groove 2, and the side wall of a continuous boss main body 1 of oil filler point 3 is connected with an oil groove 2；The oil groove 2
The hand of spiral it is identical with the rotation direction of equipped rotating shaft；Each oil filler point 3 is provided with the oilhole lid 4 of pairing；It is described
An annular chip area 5 is offered on the tail end inwall of axle sleeve main body 1；The tail end of each oil groove 2 is connected with chip area 5
