Abstract
The present utility model discloses high temperature resistant 4 point contact ball bearings of one heavy duty of mechanical transmission fields.Comprise inner ring, outer ring, ball and seal ring, ball is between inner ring and outer ring, it is characterized in that: between inner ring and the raceway of outer ring, completely fill ball, the gap of inner ring and cycle surface is provided with seal ring, inner ring is combined by 2 half inner rings, 2 junction planes of 2 half inner rings adopt concaveconvex structure, are bolted to connection; Described seal ring employing material is the springhole seal ring of spring steel.The utility model has heavy duty, high temperature resistant and improve the advantage such as sealing.
Description
Technical field
The utility model relates to high temperature resistant 4 point contact ball bearings of one heavy duty of mechanical transmission fields.
Background technique
Bearing is a kind of important spare part in contemporary machinery.Its major function is supported mechanical solid of rotation, reduces the friction factor in its movement process, and ensures its rotating accuracy.By the difference of motor element frictional property, bearing can be divided into rolling bearing and the large class of sliding bearing two, rolling bearing is generally made up of outer ring, inner ring, rolling element and retainer four part, retainer makes ball interval be evenly distributed in the raceway of Internal and external cycle, 2, ball and raceway contact, the main radial force of ball bearing.
Summary of the invention
The purpose of the present utility model is the limitation overcoming existing bearing, and providing a kind of does not novelly have high temperature resistant 4 point contact ball bearings of the heavy duty of retainer.
The present utility model is achieved through the following technical solutions:
High temperature resistant 4 point contact ball bearings of a kind of heavy duty, comprise inner ring, outer ring, ball and seal ring, ball is between inner ring and outer ring, it is characterized in that: between inner ring and the raceway of outer ring, completely fill ball, the gap of inner ring and cycle surface is provided with seal ring, inner ring is combined by 2 half inner rings, 2 junction planes of 2 half inner rings adopt concaveconvex structure, be bolted to connection, both sealing and resistance to high temperature had been improved, solve again the assembly problem of special construction sealing, adopt and completely fill spherical structure and enhance bearing capacity, four point cantact can bidirectional stress; Described seal ring employing material is the springhole seal ring of spring steel, has both improved sealing and resistance to high temperature, and has solved again the assembly problem of special construction sealing.
The utility model has novel structure, heavy duty is high temperature resistant and improve the features such as sealing.
Accompanying drawing explanation
Fig. 1 is the high temperature resistant 4 point contact ball bearing sectional drawings of heavy duty;
Fig. 2 is springhole ring structure figure.
In figure: springhole seal ring 1, outer ring 2, steel ball 3, bolt and nut 4, two halves inner ring 5.
Embodiment
Below in conjunction with accompanying drawing, content of the present utility model is described further:
As shown be the high temperature resistant 4 point contact ball bearing sectional drawings of heavy duty, comprise springhole seal ring 1, outer ring 2, steel ball 3, bolt and nut 4, two halves inner ring 5.
This patent is a kind of novel ball 4 bearing not having retainer, and providing a kind of does not novelly have high temperature resistant 4 point contact ball bearings of the heavy duty of retainer.
Its structural feature:
1. adopt and completely fill spherical structure and enhance bearing capacity, four point cantact can bidirectional stress;
2. between inside and outside circle rib, gap is very little, and employing material is the springhole seal ring of spring steel, has both improved sealing and resistance to high temperature, solves again the assembly problem of special construction sealing;
3. two halves inner ring adopts convex-concave combination to add screw fixed structure, ensure that manufacture and service precision, improves usability.
This structure has a wide range of applications at iron and steel and heavy machinery industry.
Claims (2)
1. high temperature resistant 4 point contact ball bearings of heavy duty, comprise inner ring, outer ring, ball and seal ring, ball is between inner ring and outer ring, it is characterized in that: between inner ring and the raceway of outer ring, completely fill ball, the gap of inner ring and cycle surface is provided with seal ring, inner ring is combined by 2 half inner rings, and 2 junction planes of 2 half inner rings adopt concaveconvex structure, are bolted to connection.
2. high temperature resistant 4 point contact ball bearings of heavy duty according to claim 1, is characterized in that: described seal ring employing material is the springhole seal ring of spring steel.
