Abstract
The utility model relates to a bearing bush comprising a semicircular body and sealing fillers, wherein the inner diameter of the body is the same as that of a rotating shaft, a containing groove is arranged on the inner side of the body, the sealing fillers are arranged in the containing groove, outer sides of the sealing fillers are attached to the rotating shaft, a plurality of oil storing grooves are arranged at the bottom of the containing groove, and each oil storing groove is in bar shape. The bearing bush effectively improves sealing property of lubricating oil, improves lubricating effects of the rotating shaft and the bearing bush, and ensures service life of the bearing bush.
Description
Technical field
The utility model relates to a kind of bearing parts, and 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.
The model utility content
The utility model purpose is for the deficiency that overcomes existing technology a kind of bearing shell that improves lubricating efficiency and sealing effect to be provided.
For achieving the above object, the technological scheme that the utility model adopts is: 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 utility model compared with prior art has advantage:
A kind of bearing shell of the utility model scheme, 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.
Description of drawings
Below in conjunction with accompanying drawing the utility model technological scheme is described further:
Accompanying drawing 1 is the three-dimensional exploded view of the bearing shell of the utility model;
Accompanying drawing 2 is the structural representation of the bearing shell of the utility model when using;
Wherein: 1, body; 2, containing groove; 3, oil storage tank; 4, stuffing box packing; 5, running shaft.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to specify.
Below only be the concrete exemplary applications of the utility model, the protection domain of the utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technological scheme of formation, all drop within the utility model rights protection scope.
