Abstract

The invention provides a rolling element and retainer integrated high-speed heavy-load rolling bearing which comprises a bearing outer ring, a bearing inner ring, a rolling element and a retainer. The bearing outer ring and the bearing inner ring are concentrically installed, an outer groove is formed in the inner side of the bearing outer ring, an inner groove is formed in the outer side of the bearing inner ring, a through hole is formed in the side face of the rolling body between the outer groove and the inner groove, and the retainer is connected with the rolling body through the through hole. The rolling body and the inner and outer rings of the bearing adopt the characteristic of keeping the high rotating speed of the ball bearing by point contact, the bearing capacity is improved by adopting a full-roller mode, the structure is simple, the cost is low, and the application is wide.

Description

Rolling element and cage integrated high-speed heavy-load rolling bearing

Technical Field

The invention relates to the field of bearings, in particular to a rolling element and retainer integrated high-speed heavy-load rolling bearing.

Background

The rolling bearing is an important part in the modern mechanical equipment. Its main function is to support the mechanical rotator, reduce the friction coefficient in its motion process and ensure its rotation precision. Rolling bearings are generally composed of an outer ring, an inner ring, a rolling body and a retainer, and are classified into two types, i.e., ball bearings and roller bearings, according to the shape of the rolling body. Ball bearings rotate at a high speed with low noise but low bearing capacity, while roller bearings have high bearing capacity but relatively low rotational speed. Both of these types of rolling bearings have drawbacks in terms of applicability.

Disclosure of Invention

The invention aims to provide a rolling element and retainer integrated high-speed heavy-load rolling bearing to overcome the defects in the existing product.

The purpose of the invention is realized by the following technical scheme: a rolling element and cage integrated high-speed heavy-load rolling bearing comprises a bearing outer ring, a bearing inner ring, a rolling element, a cage and an elastic gasket. The bearing inner ring is concentrically arranged with the bearing outer ring, an outer groove is arranged on the inner side of the bearing outer ring, an inner groove is arranged on the outer side of the bearing inner ring, the rolling body is arranged between the outer groove and the inner groove, a through hole is formed in the side face of the rolling body, the retainer is connected with the rolling body through the through hole, and the retainer and the rolling body are separated through the elastic gasket.

Furthermore, the rolling body is in point contact with the bearing outer ring and the bearing inner ring, so that friction in the motion process is effectively reduced, and the rolling bearing has the characteristic of high rotating speed.

Furthermore, the rolling bodies are in a full-roller form and are arranged tightly, so that the force of each rolling body is small, and the rolling bearing has strong bearing capacity.

Preferably, the number of the rolling bodies is 9, and the diameter of the through hole on the side surface of the rolling body is 10 mm.

Preferably, all the parts are made of metal.

The invention has the beneficial effects that:

due to the adoption of the technical scheme, the invention has the following advantages: the rolling element and the inner ring and the outer ring of the bearing are in point contact to keep the ball bearing at a high rotating speed, the bearing capacity is improved in a full roller mode, and the rolling element and retainer integrated high-speed heavy-load rolling bearing is simple in structure, low in cost and wide in application.

Detailed Description

The technical scheme of the invention is further specifically described by the following embodiments and the accompanying drawings.

As shown in fig. 1, 2, 3, 4, and 5, a rolling bearing with rolling elements and a cage integrated with each other for high speed and heavy load includes a bearing outer ring 1, a bearing inner ring 2, rolling elements 3, a cage 4, and an elastic washer 5. Bearing inner race 1 with bearing inner race 2 installs with one heart, 1 inboard of bearing inner race is equipped with

outer recess

101, 2 outsides of bearing inner race are equipped with inner groove 201, adorn between outer recess 101 and the inner groove 201 rolling element 3, the 3 side of rolling element are equipped with through hole 301, holder 4 passes through hole 301 connects rolling element 3, pass through between holder 4 and the rolling element 3 resilient pad 5 separation.

The rolling body 3 is in point contact with the bearing outer ring 1 and the bearing inner ring 2, so that friction in the motion process is effectively reduced, and the rolling 3 bearing has the characteristic of high rotating speed. The rolling bodies 3 are in a full roller form and are arranged tightly, so that the force shared by each rolling body 3 is small, and the rolling bearing has high bearing capacity.

The number of the rolling elements 3 is preferably 9, and the diameter of the through-hole 301 in the side surface of the rolling element 3 is preferably 10 mm. All the parts are preferably made of metal.

The present invention is not limited to the above-described embodiments, which are described in detail and with particularity, but should not be construed as limiting the scope of the invention. Any other products with various forms can be obtained in the light of the present invention, but any changes in the size or material, which are the same or similar to the technical solution of the present application, fall within the protection scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
