Description
Technical field
The present invention relates to the technical field of bearing, specially a kind of high temperature and high speed is high to carry bearing.
Background technology
Bearing is a kind of important spare part in contemporary plant equipment.Its major function is the mechanical rotary body of support, is reduced
Coefficient of friction in its motion process, and ensure its rotating accuracy.
The existing bearing list of in the market realizes high temperature, high speed and high carrying row from precision, noise etc. by grease,
As a result undesirable, because the structure of bearing does not change, the rotational velocity of steel ball is big, and coefficient of friction is big, and internal temperature is high, no
Beneficial to high speed, high temperature, high carrying row.
The rubber section of traditional bearing sealing ring is easily separated from metal portion, and then causes sealing effectiveness to reduce, meanwhile, cause
The quality of bearing both sides sealing circle is uneven, is unfavorable for bearing high-speed cruising.
The content of the invention
In view of the deficienciess of the prior art, it is an object of the invention to provide a kind of high load bearing of high temperature and high speed.
To achieve the above object, the invention provides following technical scheme：A kind of bearing suitable for the high load of high temperature and high speed,
Including inner ring, outer ring, several balls and sealing ring being located between inner ring and outer ring, described inner ring is provided with the first raceway,
Outer ring is provided with the second raceway, it is characterised in that：The radius of curvature of the second described raceway is more than the radius of curvature of the first raceway.
The first described raceway is provided with nano coating, and the second described raceway is provided with nano coating.
The radius of curvature of the first described raceway is slightly larger than the radius of ball.
Described inner ring and outer ring are formed by special thermal treatment technique.
Described sealing ring includes circle body and the seal being set in outside circle body, and it is in annulus that described circle body periphery, which is provided with,
The embedded division of shape, the inner surface of the embedded division are adapted to annular groove in interior be provided with of wavy, described seal with embedded division surface.
Contrast the deficiencies in the prior art, beneficial effect caused by technical scheme provided by the invention：1. the linear speed of inner ring
Degree is more than the design of the radius of curvature of the first raceway by the radius of curvature of the second raceway so that steel more than the linear velocity of outer ring
The cornerite of ball diminishes, and steel ball rotational velocity diminishes, and steel ball frictional force diminishes, and internal temperature reduces, then so that steel ball is more suitable
Close and worked under hot environment.2. by setting nano coating in the first raceway and the second raceway, further such that the friction of steel ball
Power reduces, and then improves the speed of service of bearing.Inner ring and outer ring described in 3. are formed by Technology for Heating Processing, make fatigue
Life-span improves 70% than common load.

Embodiment
The present invention will be further described by reference picture 1- Fig. 4.
It is a kind of suitable for the high bearing carried of high temperature and high speed, if including inner ring 1, outer ring 2, being located between inner ring 1 and outer ring 2
Dry ball 3 and sealing ring 4, described inner ring 1 are provided with the first raceway 11, and outer ring 2 is provided with the second raceway 12, it is characterised in that：
The radius of curvature of the second described raceway 12 is more than the radius of curvature of the first raceway 11, the radius of curvature of the first described raceway 11
It is slightly larger than or the radius of approximate ball 3.
Because bearing is during operation, the linear velocity of inner ring 1 is more than the linear velocity of outer ring 2, passes through the second raceway 12
Radius of curvature is more than the design of the radius of curvature of the first raceway 11 so that the cornerite of steel ball diminishes, and cornerite here refers to axle
Raceway diminishes to the parcel scope of steel ball when carrying row, and steel ball rotational velocity diminishes, and steel ball frictional force diminishes, internal temperature drop
It is low, then so that steel ball is more suitable for working under hot environment.
The first described raceway 11 is provided with nano coating 5, and the second described raceway 12 is provided with nano coating 5.
By setting nano coating 5 in the first raceway 11 and the second raceway 12, further such that the frictional force of steel ball reduces,
And then improve the speed of service of bearing.
Described inner ring 1 and outer ring 2 is formed by special thermal treatment technique, and the special thermal treatment is to first pass through low temperature again
High-temperature process, fatigue life ratio common load is set to improve 70%.
Described sealing ring 4 includes circle body 41 and the seal 42 being set in outside circle body 41, the described periphery of circle body 41
Provided with the embedded division 43 in annular shape, the inner surface of the embedded division 43 is in wavy, passes through wavy design so that as
The seal 42 of metal portion can be combined preferably with the circle body 41 as rubber section, prevent rubber section from departing from metal portion
Phenomenon, on the one hand ensure sealing effectiveness, on the other hand ensure the uniform qualities of bearing both sides, be provided with described seal 42
Annular groove is adapted to the surface of embedded division 43.
Presently preferred embodiments of the present invention is the foregoing is only, is not intended to limit the invention, those skilled in the art exists
Common variations and alternatives are carried out in the range of technical solution of the present invention should all include within the scope of the present invention.
