Description

A structurally reinforced rolling bearing

technical field

The utility model relates to the field of bearings, in particular to a structurally reinforced rolling bearing.

Background technique

Bearing is an important part of contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during the movement of the mechanical rotating body, and ensure its rotation accuracy.

According to the different friction properties of moving elements, bearings can be divided into two categories: rolling bearings and sliding bearings. Among them, rolling bearings have been standardized and serialized, but compared with sliding bearings, their radial size, vibration and noise are larger, and the price is also higher. .

Rolling bearings are generally composed of four parts: outer ring, inner ring, rolling body and cage. The rolling body is usually arranged between the outer ring and the inner ring. The axial support structure of the inner ring of the bearing has low strength, which reduces the scope of application and needs to be strengthened.

Utility model content

The purpose of the utility model is to provide a structurally reinforced rolling bearing, which improves the structural strength, especially the axial support structure of the inner ring of the bearing.

For this purpose, the utility model adopts the following technical solutions:

A structurally reinforced rolling bearing, comprising: a bearing inner ring and a bearing outer ring, the bearing inner ring is concentrically arranged in the bearing outer ring, and a ring of balls is arranged between the bearing inner ring and the bearing outer ring for rolling connection, The outer ring of the bearing is provided with an annular reinforced push plate on one side of the inner ring of the bearing, a ring of reinforced steel balls is arranged between the annular reinforced push plate and the inner ring of the bearing, The shape strengthens the spring clip on the outside of the push plate.

Wherein, a cage is arranged outside the ball.

Wherein, the inner wall of the bearing outer ring is concavely provided with installation grooves corresponding to the spring clips.

Wherein, the inner surface of the ring-shaped reinforced push plate is provided with several arc grooves corresponding to a single reinforced steel ball.

Wherein, one side of the inner ring of the bearing is provided with an annular groove corresponding to a ring of reinforcing steel balls.

Wherein, the end of the outer ring of the bearing is provided with an annular sealing plate located outside the inner ring of the bearing, the end of the outer ring of the bearing is concavely provided with an embedding groove, and the inner surface of the annular sealing plate is provided with a seal extending into the embedding groove. ring, the annular sealing plate and the sealing ring are an integrated rubber structure.

Beneficial effects of the utility model: a structurally reinforced rolling bearing uses reinforced steel balls and ring-shaped reinforced push plates to increase the axial structural strength, strengthen the axial support strength for the inner ring of the bearing, reduce the wear of the balls, and improve the durability. The scope of application is wider.

Fig. 1 is the structural representation of the utility model.

detailed description

The technical scheme of the utility model will be further described below in conjunction with FIG. 1 and through specific embodiments.

A structurally reinforced rolling bearing, comprising: a bearing inner ring 2 and a bearing outer ring 1, the bearing inner ring 2 is concentrically arranged in the bearing outer ring 1, and a bearing inner ring 2 and the bearing outer ring 1 are provided with a The ring balls 3 are connected by rolling, which is beneficial to the rotation of the bearing inner ring 2. The bearing outer ring 1 is provided with an annular reinforced push plate 11 on one side of the bearing inner ring 2, and the annular reinforced push plate 11 is connected with the bearing A ring of reinforced steel balls 9 is arranged between the inner rings 2. When the bearing inner ring 2 is axially stressed, the reinforced steel balls 9 are used to transmit the force to the annular reinforced push plate 11. The reinforced steel balls 9 effectively support the rotation of the bearing inner ring 2, reducing The stress and wear of the ball 3 have good durability.

The bearing outer ring 1 is provided with a spring clamp 12 located outside the annular reinforced push plate 11 , and the annular reinforced push plate 11 is limited by the spring clamp 12 .

In this embodiment, the outer side of the balls 3 is provided with a cage 4, and the cage 4 is used to maintain the distance between the balls 3, so that the balls 3 are evenly distributed and stressed, and the structural stability is improved.

In this embodiment, the inner wall of the bearing outer ring 1 is concavely provided with a mounting groove 8 corresponding to the spring clip 12 , the spring clip 12 is relatively convenient to install and disassemble, and the maintenance convenience is improved.

In this embodiment, the inner surface of the ring-shaped reinforced push plate 11 is provided with several arc grooves 10 corresponding to a single reinforced steel ball 9, and the reinforced steel ball 9 is limited by the circular arc groove 10, so that the space between the reinforced steel balls 9 Spaced apart from each other and evenly distributed.

In this embodiment, one side of the bearing inner ring 2 is provided with an annular groove 13 corresponding to a circle of reinforcing steel balls 9 to limit the position of a circle of reinforcing steel balls 9 and improve structural stability.

In this embodiment, the end of the bearing outer ring 1 is provided with an annular sealing plate 6 located outside the bearing inner ring 2 to reduce the adverse effect of dust on the balls 3, and the end of the bearing outer ring 1 is concavely provided with an embedding groove 5 The inner surface of the annular sealing plate 6 is provided with a sealing ring 7 extending into the embedded groove 5, which is convenient for installation. The annular sealing plate 6 and the sealing ring 7 are an integrated rubber structure, and the structure is stable.

The above content is only a preferred embodiment of the present utility model. For those of ordinary skill in the art, according to the idea of the present utility model, there will be changes in the specific implementation and scope of application. The content of this specification should not be understood as Limitations on the Invention.
