Abstract
The invention discloses a bearing bush which comprises a semi-annular body and sealing packing. The inner diameter of the body is identical to that of a rotating shaft, a holding groove is disposed on the inner side of the body, the sealing packing is disposed in the holding groove, the outer side of the sealing packing clings to the rotating shaft, and a plurality of strip-shaped oil storage grooves are disposed at the bottom of the holding groove. The bearing bush has the advantages that a sealing performance of lubricating oil is effectively improved, lubrication effects of the rotating shaft and the bearing bush are enhanced, and the service life of the bearing bush is guaranteed.
Description
Technical field
The present invention relates to a kind of bearing parts, especially a kind of bearing shell that is used to seal belongs to shaft sealing part technical field.
Background technique
In the machinery industry, the bearing shell that is fixed on the running shaft all is the semi-round ring shape of watt shape.When running shaft rotates, the lubricant oil of lubricate is arranged all between bearing shell and the running shaft.Because running shaft is high speed rotating ceaselessly, produce great amount of heat, also than under the condition with higher,, and made between bearing shell and the running shaft in ambient temperature with regard to direct friction often because insufficient lubrication.So long-time friction can produce very high temperature, if untimely interpolation lubricant oil is easy to burn out bearing shell, that will damage other parts, causes mechanical disorder.So general machine run after a period of time, just needs to shut down to add lubricant oil, has wasted a lot of times.And the sealing effect of lubricant oil between bearing shell and running shaft neither be very high, leaks easily, causes the waste of lubricant oil.
Summary of the invention
Technical problem to above-mentioned existence the objective of the invention is: proposed a kind of bearing shell that improves lubricating efficiency and sealing effect.
Technical solution of the present invention is achieved in that a kind of bearing shell, comprises semi-round ring shape body and stuffing box packing; The internal diameter of said body is identical with running shaft; Said body inboard has containing groove; Be provided with stuffing box packing in the said containing groove, and the outside of stuffing box packing and running shaft applying; The bottom of said containing groove has a plurality of oil storage tanks, and oil storage tank is bar shaped.
Preferably, said oil storage tank is eight.
Preferably, the degree of depth of said containing groove is greater than the degree of depth of oil storage tank.
Because the utilization of technique scheme, the present invention compared with prior art has advantage:
Bearing shell of the present invention, it adopts the stuffing box packing that is provided with in the containing groove, and the locking of the lubricant oil between bearing shell and the running shaft is a labyrinth oil film, has improved the sealing of lubricant oil; And the oil storage tank that has bottom the containing groove, can the lubricant oil that store be formed a circulation loop between bearing shell and running shaft, improved the lubrication effect of running shaft and bearing shell, in the working life of also having improved bearing shell, guaranteed the normal operation of machine.
