Abstract
The utility model provides an improved roller bearing which comprises a bearing body, a bearing lining, a sealing gland, an oil retainer and a seal ring, and is characterized in that the bearing lining is a copper covered steel bearing lining, and the internal diameter of the bearing lining is 0.15-0.9mm larger than the external diameter of a roller shaft neck. Through the above structure, the bearing lining can use other materials as well as copper, the copper covered steel bearing lining has a better cooling effect, the clearance between the roller shaft neck and the bearing lining can be effectively matched, and the service life of the bearing lining is prolonged. Therefore, the service life of the whole bearing is prolonged and the safety is improved.
Description
Technical field
The novel sliding bearing that relates to the work rotational support of a kind of roller bearing, particularly a kind of roller by the roller journal two ends of this reality.
Background technique
The work rotational support of roller is born by the sliding bearing at roller journal two ends.Bearing support is assemblied in the bearing window frame of Rack Body, and it is the major part that supports roller, guarantees its ability proper functioning.
The non-constant of the operating conditions of roller bearing should bear the heavier rotating load of roller, and so long-term work under high temperature environment very again is all very high to the requirement of roller bearing.
Bearing bush in the bearing is the part that produces relative movement, bearing load with roller journal in the sliding bearing, bigger friction is arranged, the matching gap of the thermal diffusivity of bearing bush, roller journal and bearing bush be the working life that is directly connected to whole bearing.
Summary of the invention
For making bearing that good thermal diffusivity arranged; Improve the working life and the Security of bearing; The utility model provides a kind of roller bearing of improvement, is made up of bearing support, bearing bush, sealing gland, flinger ring and seal ring, it is characterized in that: said bearing bush adopts the steel-in-copper bearing bush.
The internal diameter of described bearing bush (2) is than the big 0.15～0.9mm of external diameter of roller journal (6).
After adopting said structure; Bearing bush is not only limited to use copper, and the bearing bush of steel-in-copper has good thermal diffusivity, and roller journal can effectively be cooperated with the gap of bearing bush simultaneously; Improve the working life of axle bush, thereby improved the working life and the Security of whole bearing.
The utility model low cost of manufacture has also done the practicability of this product high.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model texture edge schematic representation.
Be denoted as among the figure: 1 bearing support, 2 bearing bushs, 3 sealing glands, 4 flinger rings, 5 seal rings, 6 roller journals.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the utility model title is done further to detail, but do not constitute any restriction the utility model.
Like Fig. 1, shown in 2:
A kind of roller bearing of improvement is made up of bearing support 1, bearing bush 2, sealing gland 3, flinger ring 4 and seal ring 5, it is characterized in that: said bearing bush 2 adopts the steel-in-copper bearing bush.
The internal diameter of described bearing bush 2 is than the big 0.15～0.9mm of external diameter of roller journal 6.
The effect of the sealing gland 3 among the figure, flinger ring 4 and seal ring 5 mainly is to be used for preventing that the circulating lubricating oil of certain pressure from outflowing at bearing bush 2 places.
After adopting said structure; Bearing bush is not only limited to use copper, and the bearing bush 2 of steel-in-copper has good thermal diffusivity, and roller journal 6 can effectively be cooperated with the gap of bearing bush 2 simultaneously; Improve the working life of bearing bush, thereby improved the working life and the Security of whole bearing.
The utility model low cost of manufacture has also done the practicability of this product high.
