Description

Self-locking bearing

Technical Field

The utility model relates to a bearing specifically relates to a self-locking bearing.

Background

The Bearing (Bearing) is an important part in the modern mechanical equipment, and the main function is to support the mechanical rotating body, reduce the friction coefficient in the movement process and ensure the rotation precision of the mechanical rotating body. The bearings can be classified into rolling bearings and sliding bearings according to the frictional properties of the moving elements. Rolling bearings have been standardized and serialized, but have a larger radial size, vibration and noise, and a higher price than sliding bearings. The rolling bearing generally comprises an outer ring, an inner ring, a rolling body and a retainer; rolling bearings are classified into ball bearings and roller bearings according to the shape of the rolling elements.

Whether the bearing is installed or not affects the precision, the service life and the performance of the bearing. The bearings are typically mounted in an interference fit, which is difficult to assemble and disassemble and the useful life of the bearings is reduced if the bearings are not mounted using the correct methods and tools. Of all the prematurely occurring failed bearings, about 16% are due to improper installation or use of the wrong installation technique.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a self-locking bearing, this self-locking bearing can improve installation effectiveness and installation quality effectively.

In order to achieve the above object, the utility model provides a self-locking bearing, include: the self-locking ring comprises an outer ring, an inner ring, a plurality of balls and a self-locking ring; the inner ring is positioned inside the outer ring; the balls are positioned between the outer ring and the inner ring and can roll between the outer ring and the inner ring; a convex block extends outwards from one side of the inner ring, a through hole is formed in the convex block, and a self-locking circular ring is arranged in the through hole.

Preferably, the self-locking ring is internally formed with an internal thread.

Preferably, the inner part of the inner ring is of a hollow structure and is communicated with the self-locking circular ring.

Preferably, an internal thread is arranged in the inner ring, and the diameter of the internal thread of the inner ring is the same as that of the internal thread of the self-locking ring.

Preferably, the bumps are in a regular hexagonal prism structure.

In the above technical solution, the self-locking bearing provided by the present invention has a projection extending outward from one side of the inner ring, a through hole is formed inside the projection, and a self-locking ring is arranged inside the through hole; in the installation process, the self-locking function of the self-locking ring effectively prevents the bearing position from deviating, the outer ring can be installed on the bearing support, the problem that the bearing is difficult to install in the installation process is solved, the bearing can be installed through the wrench, the bearing can be directly installed on the screw rod, and the matching problem does not need to be considered.

Other features and advantages of the present invention will be described in detail in the detailed description which follows.

Detailed Description

The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings. It is to be understood that the description of the embodiments herein is for purposes of illustration and explanation only and is not intended to limit the invention.

In the present invention, unless otherwise specified, the directional terms included in the terms "inner" and "outer" merely represent the directions of the terms in a conventional use state or are colloquially known by those skilled in the art, and should not be construed as limiting the terms.

The utility model provides a self-locking bearing, include: the self-locking device comprises an outer ring 1, an inner ring 2, a plurality of balls 3 and a self-locking circular ring 4; the inner ring 2 is positioned inside the outer ring 1; a plurality of balls 3 are positioned between the outer ring 1 and the inner ring 2, and the balls 3 can roll between the outer ring 1 and the inner ring 2; a convex block extends outwards from one side of the inner ring 2, a through hole is formed inside the convex block, and a self-locking circular ring 4 is arranged inside the through hole.

The self-locking bearing is provided with a convex block extending outwards from one side of the inner ring 2, a through hole is formed inside the convex block, and a self-locking circular ring 4 is arranged inside the through hole; in the installation process, the self-locking function of the self-locking ring 4 effectively prevents the bearing position from deviating, the outer ring can be installed on the bearing support, the problem that the bearing is difficult to install in the installation process is solved, the bearing can be installed through the wrench, the bearing can be directly installed on the screw rod, and the matching problem does not need to be considered.

The utility model discloses in, the inside of auto-lock ring 4 can be smooth wall, also can be other structures, in order to further make auto-lock ring 4 can install on the lead screw effectively, preferably, the inside internal thread that is formed with of auto-lock ring 4. The offset of the bearing can be further prevented by the fit of the internal thread with the external thread of the screw rod.

In the above embodiment, in order to further improve the stability of the bearing, it is preferable that the inner ring 2 has a hollow structure and communicates with the self-locking ring 4. The inner ring 2 and the self-locking ring 4 are simultaneously fixed on the screw rod, so that the stability of the bearing is further improved.
