Description

Plane thrust bearing

Technical Field

The utility model relates to a thrust bearing technical field especially relates to a plane thrust bearing.

Background

The existing plane thrust bearing adopts the clamping ball between the upper ring and the lower ring, the upper ring and the lower ring are sealed through the oil seal, however, the service life of the oil seal is short, once the oil seal is damaged, dust enters the space between the upper ring and the lower ring, and the ball is easy to generate heat and wear during operation, so that the bearing is damaged.

To solve the above problems, we propose a flat thrust bearing.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the defects existing in the prior art and providing a plane thrust bearing.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the plane thrust bearing comprises an outer ring, an inner ring, rolling bodies, an inner retainer and an outer retainer, wherein the inner ring is sleeved inside the outer ring, the rolling bodies are arranged and uniformly arranged between the inner wall of the outer ring and the outer wall of the inner ring, the inner retainer is sleeved between the outer wall of the inner ring and the rolling bodies, and the outer retainer is sleeved between the inner wall of the outer ring and the rolling bodies.

Preferably, the inner side of the outer ring is provided with a ring groove, and the outer retainer is clamped in the ring groove of the outer ring.

Preferably, one side of the inner ring, which is close to the inner retainer, is provided with an annular gap, and a piston ring is arranged in the gap.

Preferably, the outer wall of the inner retainer and the inner wall of the outer retainer are both provided with arc-shaped grooves corresponding to the rolling bodies.

Preferably, the outer holder is a hollow structure, and a plurality of oil holes are formed in the inner arc surface of the outer holder corresponding to the rolling body.

Preferably, the rolling bodies are balls.

The utility model has the advantages that:

1. in the utility model, lubricating oil is injected into the outer retainer, so that the surface of the rolling body can be well lubricated through the plurality of oil holes, the rolling body can rotate, so that the surface of the rolling body can be uniformly coated with the lubricating oil, the effect is good, and the lubricating oil is periodically supplied, so that the service life can be prolonged to the maximum extent;

2. the utility model discloses in, the even card of rolling element is in the arc wall on interior holder and outer holder, makes interior holder firmly compress tightly the rolling element on outer holder through the installation piston ring, has strengthened the stability of structure.

In the figure: the structure comprises an outer ring 1, an inner ring 2, a rolling body 3, an inner retainer 4, an outer retainer 5, an oil hole 501 and a piston ring 6.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

In this embodiment, referring to fig. 1 to 4, a planar thrust bearing includes an outer ring 1, an inner ring 2, a plurality of rolling bodies 3, an inner cage 4, and an outer cage 5, where the inner ring 2 is sleeved inside the outer ring 1, the rolling bodies 3 are provided and uniformly arranged between an inner wall of the outer ring 1 and an outer wall of the inner ring 2, the inner cage 4 is sleeved between an outer wall of the inner ring 2 and the rolling bodies 3, and the outer cage 5 is sleeved between an inner wall of the outer ring 1 and the rolling bodies 3.

The ring groove is formed in the inner side of the outer ring 1, the outer retainer 5 is clamped in the ring groove of the outer ring 1, an annular opening is formed in one side, close to each other, of the inner ring 2 and the inner retainer 4, a piston ring 6 is installed in the opening, arc-shaped grooves corresponding to the rolling bodies 3 are formed in the outer wall of the inner retainer 4 and the inner wall of the outer retainer 5, the outer retainer 5 is of a hollow structure, a plurality of oil holes 501 are formed in the inner arc surface corresponding to the rolling bodies 3, and the rolling bodies 3 are balls.

The specific implementation mode is as follows: this device is a plane thrust bearing, this device is when using, earlier with 5 inside injected lubricating oil of outer holder, secondly, can lubricate 3 surfaces of rolling element well through a plurality of oilholes 501, and because rolling element 3 can carry out the rotation, lubricating oil can be paintd uniformly on its surface, make the wearing and tearing that generate heat of rolling element 3 obviously reduce, excellent in use effect, in addition, periodic supply lubricating oil, can furthest increase of service life, the even card of rolling element 3 is in the arc wall on inner holder 4 and outer holder 5, make inner holder 4 firmly compress tightly rolling element 3 on outer holder 5 through installation piston ring 6, the stability of structure has been improved greatly.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
