Abstract
The utility model discloses a self-lubricating connection pin shaft to solve the problem of shortening the service life of a copper sleeve caused by poor lubrication and friction between the connection pin shaft and the copper sleeve. The self-lubricating connection pin shaft comprises a connection pin shaft body; an oil hole with an opening at one end is processed in the centre part of the connection pin shaft body along the axial direction; an oil injection nozzle is arranged at an open end of the oil hole; a spiral oil storage tank is processed on the outer periphery of the connection pin shaft body; the bottom part of the oil storage tank is connected with the oil hole in the centre of the connection pin shaft body to form a communicated oil passage. The self-lubricating connection pin shaft disclosed by the utility model can be widely applied to various mechanical devices after being assembled together with the copper sleeve and is filled with oil by five minutes in one time; a certain amount of lubricating grease can be stored between the oil storage tank and the copper sleeve after oil injection, so that the service time is long, and the lubricating effect is improved greatly, and further the service life of the device is prolonged, and the maintenance workload is reduced particularly when the self-lubricating connecting pin shaft is in the places with complicated space and maintenance difficulty.
Description
Technical field
But the utility model relates to a kind of connection bearing pin of selflubricating.
Background technique
Connecting the assembling of bearing pin and copper sheathing is machinery movable part Placement commonly used, and in cold rolling machinery, it is exactly this Placement of usefulness that the tension force pressure roller connects bearing pin.But, connect in this Placement and have friction between bearing pin and the copper sheathing, if lubricated bad, the working life that will reduce copper sheathing.Because the metallurgical equipment complex structure is installed compactness, the work on the spot environment is abominable, in case copper sheathing is damaged, it is quite complicated more to change jobs.
The model utility content
The purpose of the utility model is to overcome the existing technology defective, but a kind of connection bearing pin of selflubricating is provided, to reduce the mechanical friction that connects between bearing pin and the copper sheathing.
But the technological scheme of the utility model is achieved in that the connection bearing pin of selflubricating; Comprise connecting the bearing pin body that it is, is connecting the oil hole that bearing pin body center portion is processed with an end opening vertically; The oil hole opening end is equipped with pump nozzle; Be processed with oil storage tank connecting bearing pin body outer peripheral surface, the oil storage tank bottom through upright opening with is connected bearing pin body center oil hole and links to each other the oil circuit that formation communicates.
Preferably, said oil storage tank is a spirality.
Can be widely used in all kinds of machinery after the utility model and the copper sheathing assembling, an oiling only needs five minutes, after the oiling; Can store a certain amount of lubricating grease between oil storage tank and the copper sheathing; Service time is long, has improved lubrication effect greatly, thereby has prolonged service life of equipment.Particularly, reduced maintenance workload in the place of spatial complex, repair and maintenance difficulty.
Description of drawings
Fig. 1 is the utility model plan view.
Fig. 2 is the utility model sectional view.
Among the figure, 1-connects the bearing pin body; The 2-oil hole; The 3-pump nozzle; The 4-oil storage tank; The 5-upright opening
Embodiment
Further describe below in conjunction with accompanying drawing:
Like Fig. 1, shown in Figure 2; But the connection bearing pin of selflubricating comprises connecting bearing pin body 1, is connecting the oil hole 2 that bearing pin body 1 center portion is processed with an end opening vertically; Oil hole 2 opening ends are equipped with pump nozzle 3; Be processed with the spirality oil storage tank 4 that can reduce to rub connecting bearing pin body 1 outer peripheral surface, oil storage tank 4 bottoms through upright opening 5 with is connected bearing pin body 1 center oil hole 2 and links to each other the oil circuit that formation communicates.The diameter and the pump nozzle 3 of oil hole 2 and oil storage tank 4 adapt, and the distribution of the lift angle of spirality oil storage tank 4 and upright opening 5 can be according to being connected bearing pin body 1 length choose reasonable.
During oiling, no longer need to connect bearing pin body 1 and from copper sheathing, extract, but connect pump nozzle 3 through oil gun; Drier oil is squeezed into oil hole 2, passes through upright opening 5 again, is stored between oil storage tank 4 and the copper sheathing; Overcome the unhandy difficulty of limited space fully, only two workmans of needs can accomplish the work of a lubricating point of tension force pressure roller rotating mechanism in five minutes, and life cycle reaches 1 year; Improve lubrication effect greatly, thereby prolonged service life of equipment.
Claims (2)
1. but the connection bearing pin of selflubricating; Comprise and connect the bearing pin body; It is characterized in that: connecting the oil hole that bearing pin body center portion is processed with an end opening vertically, the oil hole opening end is equipped with pump nozzle, is processed with oil storage tank at connection bearing pin body outer peripheral surface; Oil storage tank bottom through upright opening with is connected bearing pin body center oil hole and links to each other the oil circuit that formation communicates.
2. but the connection bearing pin of selflubricating according to claim 1, it is characterized in that: said oil storage tank is a spirality.
