Abstract
The utility model relates to a sliding bearing not easy to block, especially a sliding bearing of a submerged pump used for supporting or bearing a radial force suitable for chemical industry, metallurgy, coal, papermaking, pharmacy, environmental protection or other industries. An improved structure of the sliding bearing provided in the utility model is that a helical groove is disposed in the outer surface of a shaft sleeve, and extends from one end of the shaft sleeve to the other end; the helical groove in the surface of the shaft sleeve is the bidirectional multi-head helical groove. In the utility model, original smooth surface structure of the original shaft sleeve can be improved into the helical groove structure, the self-lubricating requirement of the sliding bearing can be satisfied, the problem that the shaft and the pump body are easy to block can be solved, thereby the reliability of the submerged pump can be guaranteed.
Description
Technical field
The utility model belongs to a kind of sliding bearing, particularly is applicable to the sliding bearing of the Under Water Pumps of support and bearing radial force in the industries such as chemical industry, metallurgy, coal, papermaking, pharmacy, environmental protection.
Background technique
At present, traditional Under Water Pumps sliding bearing is made up of axle sleeve and lining, and the gap between them is very little, and monolateral gap design has only 0.25～0.4mm.Sliding bearing utilization operating mode is complicated, contains solid particle through regular meeting, can cause producing between the sliding bearing moving surface scratching, and increases friction, causes locking phenomenon when serious; When self-lubricating property is not enough, first half branch lubricated less than or lack of lubrication, be easy to occur the sliding bearing locking phenomenon, seriously can cause sliding bearing to burn or burn motor.Therefore, should be directed against above problem, on original basis, improve, so that can better be applicable to more operating mode and reach the purpose that is difficult for locking.
Summary of the invention
The utility model to solve technical problem provide a kind of sliding bearing more reliably, can be suitable for more multi-operating mode and better solution selflubricating problem, fundamentally solve the easy locking phenomenon of sliding bearing.
Solving the technological scheme that the technical problem of the utility model takes is: face is processed with spiral chute in the outside of axle sleeve, and spiral chute extends to the other end from an end of axle sleeve.
The said spiral chute on axle sleeve surface is the spiral chute of two-way bull.
Described spiral fluted groove depth is 5mm, and pitch is 20mm.
The beneficial effect of the utility model is: with the smooth surface architecture advances of original axle sleeve is helical groove structure, and the requirement and the axle that can solve the sliding bearing selflubricating are prone to the phenomenon of locking with the pump housing, thereby have guaranteed the reliability that Under Water Pumps uses.
Description of drawings
Fig. 1 is the axle sleeve structure schematic representation of the utility model.
Among the figure: axle sleeve 1, spiral chute 2, keyway 3, axis hole 4.
Embodiment
Referring to Fig. 1, face is processed with the spiral chute 2 of two-way bull in the outside of axle sleeve 1, and spiral chute 2 extends to the other end from an end of axle sleeve 1, and the groove depth of spiral chute 2 is 5mm, and pitch is 20mm.When pump operation, liquid can upwards flow in the squeezing action between axle sleeve and the lining, and liquid just can lubricate all surfaces of sliding bearing like this, thereby has solved the problem of selflubricating; And solid particle also can be because of there being spiral chute, and particle can tumble and discharge along with liquid in the groove when operation, and then solved the phenomenon that has solid particle to be prone to cause the sliding bearing locking.
Claims (3)
1. sliding bearing that is difficult for locking, it is characterized in that: face is processed with spiral chute in the outside of axle sleeve, and spiral chute extends to the other end from an end of axle sleeve.
2. by the described sliding bearing that is difficult for locking of claim 1, it is characterized in that: the spiral chute on axle sleeve surface is the spiral chute of two-way bull.
3. by the described sliding bearing that is difficult for locking of claim 2, it is characterized in that: groove depth is 5mm, and pitch is 20mm.
