Abstract
The utility model relates to a pump and a bearing component having the similar structure belonging to the self-lubricating system, in particular to a new bearing component, comprising a shaft journal, an inclined hole and an oil transportation channel. The utility model is characterized in that the oil transportation channel is a spiral channel. The bad bearing lubrication effect of the present product is solved. The utility model is used in the thin oil self-lubricating system and has the advantages of simple structure, good lubricating effect, shockproofness, noise free, trouble-free operation and long cycle length. The maintenance cost is greatly reduced.
Description
Technical field
The utility model relates to the bearing part in a kind of pump and the similar structure product self lubricating system, specifically a kind of novel bearing parts.
Background technique
Traditional bearing thin oil lubrication system as shown in Figure 1, the input oil groove of its bearing part axle journal is a rectangle, as shown in Figure 2.This input oil groove is the oil lubricating system of rectangular configuration, has only when being added to the oil in the bearing support on the inclined hole of axle journal, could be with the rotation of following thin oil by axle journal, in the bearing above being transported under action of centrifugal force.When pasta descends slightly, the centrifugal force that produces during the axle journal rotation can't be transported to the thin oil in the bearing support in the top bearing, thereby top bearing is damaged because of insufficient lubrication, hot-tempered sound, vibrations occur, cause the pump running unusual, the failure-free operation cycle shortens.
Summary of the invention
Technical problem to be solved in the utility model is: the input oil groove at axle journal in the existing bearing part is the existing defective of rectangle, provides a kind of novel bearing parts, to remedy the deficiency that existing product exists.
The technical solution of the utility model is achieved in that it comprises axle journal, inclined hole and input oil groove, is characterized in that: input oil groove is a spiral chute; Spiral chute is located at the inwall of axle journal.Spiral chute of the present utility model is unidirectional double end or multi-head spiral groove, also can adopt two-way spiral groove.
The utility model is used in the thin oil self lubricating system, has simple in structure, high lubricating effect, shockproof, no hot-tempered sound, long advantage of failure-free operation cycle, greatly reduces maintenance cost.

Fig. 4 is the utility model two-way spiral groove journal structure schematic representation
Embodiment
Below in conjunction with accompanying drawing the utility model is further described:
As shown in Figure 3, the utility model comprises axle journal 1, inclined hole 2 and input oil groove 3, and input oil groove 3 is a spiral chute, and spiral chute is located at the inwall of axle journal 1.Spiral chute of the present utility model can the one-way spiral groove, in order to improve the transporting velocity of lubricant oil, can adopt double end or multi-head spiral groove.As long as sense of rotation coupling with Hand of spiral and rotor, in one-way spiral fluted shaft neck 1 rotation process, even thin oil is lossy or drop under the inclined hole 2 in the bearing support, also can automatically following thin oil be transported in the upper bearing (metal) by the centrifugal motion of spiral motion and axle journal 1, and speed is very fast, also can guarantee lubricating of two bearings up and down reliably so need not in the bearing support to refuel more continually, realize the automatic cycle of lubricant oil in bearing support.In addition, if pump rotor does not limit sense of rotation, also can adopt two-way spiral groove shown in Figure 4, no matter rotor can be realized upwards carrying automatically of lubricant oil to which direction rotation, so it has high lubricating effect, long advantage of failure-free operation cycle.
