Technical field
The utility model relates to agitator technical fields, are especially a kind of anti-wear sleeve.
Background technique
Axle sleeve is the tubular machine components covered in shaft, is a component part of sliding bearing.In general, axle sleeve
With bearing block using interference fit, and it is gap-matched with axis.There are a kind of dedicated axle sleeve applied in pump field, tool at present
Have with flowering structure: a kind of anti-wear sleeve, including sleeve body, the sleeve body are equipped with the first centre bore.The anti-wear sleeve is deposited
In not wear-resisting disadvantage, durability is poor.If cost, Er Qiehui can be greatly increased using more wear resistant alloy material
Increase difficulty of processing, increases processing cost.
Utility model content
The technical problems to be solved in the utility model be to provide it is a kind of can greatly increase wearability, the cost of material is low, processing
Convenience, the anti-wear sleeve that processing cost is low, circumferential direction has limited.
The technical solution of the utility model is to provide a kind of anti-wear sleeve having following structure, including sleeve body, institute
Sleeve body is stated equipped with the first centre bore, it is characterised in that: be additionally provided with the axle sleeve made of graphite material in the sleeve body
Liner, the end face of the front end of the axle sleeve liner protrude from one end end face of sleeve body, the rear end face of the axle sleeve liner
Lower than the other end face of sleeve body；The sleeve body is equipped with the second centre bore, the axis of second centre bore and the
The axis of one centre bore is located along the same line, and it is recessed that the inner wall of the axle sleeve liner is equipped with a plurality of circumferentially equally distributed first
Slot, the front end surface of the axle sleeve liner are equipped with quantity the second groove corresponding with the first groove, and the one of first groove
It holds and is connected with one end of corresponding second groove, circumferential position limiting structure is equipped between the sleeve body and axle sleeve liner.
The position limiting structure includes third groove and being located at sleeve body side wall on the side wall for be located at the front end of axle sleeve liner
On limited block, the limited block is located at the top of third groove.
The two sides of the limited block are equipped with the 4th groove through inside and outside wall, and the outer end of the 4th groove extends to axle sleeve
The end face of ontology.
The third groove is corresponding with one of those second groove location.
The cross section semicircular in shape of second groove, lowest surfaces are lower than the end face of sleeve body.
The quantity of first groove and the second groove is six, and the tail end end face of the sleeve body is planar junction
Structure.
After using the above structure, the utility model is had the advantage that as increasing the axle sleeve made of graphite material
Liner avoids sleeve body and connect with shaft so as to be that shaft and axle sleeve liner are rotatablely connected, and is made of graphite material
Axle sleeve have wear-resisting and facilitate the characteristic of processing, wearability, the cost of material is low, easy to process so as to greatly increasing, processing
It is at low cost.Additionally, due to circumferential position limiting structure is equipped between the sleeve body and axle sleeve liner, to make sleeve body and axis
It covers liner more preferably circumferentially to limit with the fixing seat of installation, greatly increases circumferential limit property, good limit effect.
