Abstract
The invention discloses a novel technology of a cylindrical hollow rolling element rolling bearing, which solves all the problems of the existing commonly used solid rolling element rolling bearing. At present, in a rolling bearing, the rolling bearing is of a solid rolling body structure, so that the solid rolling body is in a high-speed heavy-load operation working condition process, the physical temperature rise phenomenon generated by friction is caused, the temperature of the rolling bearing cannot be effectively reduced by self bodies, and in the temperature accumulation process, the solid rolling body is caused to generate a thermal fatigue phenomenon, and finally the rolling bearing cannot normally operate or is damaged. The solid rolling body is processed, and the hollow rolling body with the central through hole can effectively solve the technical problem of the solid rolling body. By adopting the technical scheme, the purpose of prolonging the service life of the rolling bearing of the cylindrical hollow rolling body can be achieved.
Description
One, the technical field
A cylindrical hollow rolling element rolling bearing is a rolling bearing technology with a novel structure, and relates to the field of rolling bearings.
Second, background Art
The rolling bearing parts used in the mechanical products produced by the existing automobile manufacturing, engineering machinery manufacturing and steel rolling equipment manufacturing enterprises are all rolling bodies with solid structures.
The solid rolling element rolling bearing can not effectively reduce the temperature of the rolling bearing when the temperature of the rolling bearing is physically raised on an individual body due to friction of the solid rolling element in the process of heavy-load high-speed operation working condition. During the temperature accumulation process, the solid rolling body can generate a thermal fatigue phenomenon, and finally the integral rolling bearing can not normally run or be damaged.
Third, the invention
The invention provides a cylindrical hollow rolling element rolling bearing technology with a novel technical structure, and solves all technical defects existing in the use process of the existing commonly used solid rolling element rolling bearing.
In order to solve the technical defects, the technical scheme of the invention is as follows:
the solid rolling body which is commonly adopted at present is manufactured into a cylindrical hollow rolling body with a central through hole. The cylindrical hollow rolling body can accumulate temperature rise generated by rolling body individuals in the process of normal operation working condition, and the heat is dissipated by utilizing the function of the hollow through hole in the center of the hollow rolling body. Therefore, the purpose of prolonging the service life of the rolling bearing of the cylindrical hollow rolling body can be achieved.
The invention has the beneficial effects that:
by adopting the technical scheme of the cylindrical hollow rolling element rolling bearing, the purpose of prolonging the service life of the cylindrical hollow rolling element rolling bearing can be achieved.

FIG. 2 is a schematic view of a cylindrical hollow rolling body structure
The rolling bearing comprises a rolling bearing outer ring 1, a rolling bearing inner ring 2, a cylindrical hollow rolling body 3, a cylindrical hollow rolling body central through hole 4 and a retainer 5.
Fifth, detailed description of the invention
In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the present invention will be further described in detail with reference to the accompanying drawings, which are used for explaining the present invention and are not intended to limit the present invention.
The invention is explained in more detail below with reference to the figures and examples:
please refer to (fig. 1 and 2)
The embodiment of the invention provides a cylindrical hollow rolling element rolling bearing, which comprises:
the cylindrical hollow rolling bodies 3 processed into the central through holes 4 of the cylindrical hollow rolling bodies are sequentially arranged in the retainer 5.
Then the retainer 5 is arranged in the outer ring 1 and the inner ring 2 of the rolling bearing. And the components are combined into a cylindrical hollow rolling element rolling bearing component with an integral structure.
The invention has the beneficial effects that:
by adopting the technical scheme of the cylindrical hollow rolling element rolling bearing, the purpose of prolonging the service life of the cylindrical hollow rolling element rolling bearing can be achieved.
