Abstract
The utility model relates to a kind of dustproof covers for rolling bearing.Including lid and sealing, sealing is integrally in groove type, and lid is located in groove；Sealing includes outer ring lug boss, middle interconnecting piece and inner ring lug boss；3 gas vents are provided on the lug boss of outer ring: first row stomata, second row stomata, third gas vent, first row stomata and second exhaust hole are located at the upper surface of outer ring lug boss, and third gas vent is located at the outermost of outer ring lug boss.The utility model can prevent oil stream from going out with waterproof, dust-proof, while dust-proof, be additionally provided with gas vent, solve the problems, such as during operation because fever generates negative pressure, to solve the service life for extending bearing.
Description
Technical field
The utility model relates to field of mechanical technique more particularly to a kind of dustproof covers for rolling bearing.
Background technique
Existing bearing is in order to dust-proof, waterproof, can add a dustproof cover, but when bearing runs at high speed can generate heat, axis
Negative pressure can be generated by holding, and bearing seal can be caused stuck, and jump lid, reveal rouge, to reduce bearing service life.
Utility model content
The purpose of this utility model is that in place of solving the above deficiencies in the existing technologies.
To achieve the above object, the utility model provides a kind of dustproof cover for rolling bearing, including lid and sealing
Portion, sealing are integrally in groove type, and lid is located in groove；Sealing includes that outer ring lug boss, middle interconnecting piece and inner ring are convex
The portion of rising；3 gas vents: first row stomata, second row stomata, third gas vent, first row stomata are provided on the lug boss of outer ring
It is located at the upper surface of outer ring lug boss with second exhaust hole, third gas vent is located at the outermost of outer ring lug boss.
Preferably, straight line where first row stomata and second row stomata is first straight line, third gas vent and dustproof cover
Straight line where the center of circle is second straight line, and first straight line passes through the center of circle of dustproof cover, and second straight line and third straight line are perpendicular.
Preferably, the material of sealing is nitrile rubber.
Preferably, the material of lid is cold-reduced sheet.
The utility model can prevent oil stream from going out with waterproof, dust-proof, while dust-proof, be additionally provided with gas vent, solve
Because fever leads to the problem of negative pressure in operation process, to solve the service life for extending bearing.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of dustproof cover provided by the embodiment of the utility model；
Fig. 2 is a kind of sectional view of dustproof cover provided by the embodiment of the utility model.
Specific embodiment
With reference to the accompanying drawings and examples, the technical solution of the utility model is described in further detail.
If Fig. 1-2, Fig. 1 are a kind of top view provided by the embodiment of the utility model, Fig. 2 is that Fig. 1 is cut along the face AA
The sectional view arrived.The dustproof cover includes including lid 2 and sealing, and sealing is integrally in groove type, and lid 2 is located in groove；
Sealing includes outer ring lug boss 3, middle interconnecting piece and inner ring lug boss 1；It is provided with 3 gas vents on outer ring lug boss 3:
One gas vent 31, second row stomata 32, third gas vent 33, first row stomata 31 and second row stomata 32 are located at outer ring lug boss
3 upper surface, third gas vent 33 are located at the outermost of outer ring lug boss 3.
First row stomata 31 and 32 place straight line of second row stomata are first straight line, the circle of third gas vent 33 and dustproof cover
Straight line where the heart is second straight line, and first straight line passes through the center of circle of dustproof cover, and second straight line and third straight line are perpendicular.
In one example, the material of sealing is nitrile rubber.
In one example, the material of lid 2 is cold-reduced sheet.
Dustproof cover provided by the utility model can prevent oil stream from going out with waterproof, dust-proof, while dust-proof, be additionally provided with
Gas vent solves the problems, such as during operation because fever generates negative pressure, to solve the service life for extending bearing.
Above specific embodiment has carried out further the purpose of this utility model, technical scheme and beneficial effects
It is described in detail, it should be understood that the above is only the specific embodiments of the utility model, is not used to limit originally practical
Novel protection scope, within the spirit and principle of the utility model, any modification, equivalent substitution, improvement and etc. done,
It should be included within the scope of protection of this utility model.
