Description

Thrust bearing

Technical Field

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

Background

The bearing is an important part in the modern mechanical equipment, and the main function of the bearing is to support a mechanical rotating body, reduce the friction coefficient in the movement process of the mechanical rotating body and ensure the rotation precision of the mechanical rotating body. There are various types of bearings, and among them, a thrust bearing is a bearing that is specially used to receive an axial force.

At present, along with the increase of vehicle frequency of use and cargo capacity, the axial force that thrust bearing need bear also increases gradually, however among the prior art, the axial force that thrust bearing bore is limited, and in the use, under the condition of the axial force gradual increase who bears, thrust bearing is scrapped or burns out very easily, greatly reduced bearing's life, and then can influence the stability and the security that the vehicle travel.

Disclosure of Invention

An object of the utility model is to prior art not enough, and provide a thrust bearing, its reasonable in design, convenient to use improves the axial force that thrust bearing can bear, improves the life of bearing.

The utility model provides a technical scheme that its technical problem adopted is: a thrust bearing comprises an inner ring and an outer ring, wherein a rolling body and a retainer used for fixing the rolling body are arranged between the inner ring and the outer ring, an inner groove is formed in the inner side of the end part of the outer ring, a flange matched with the inner groove is arranged at the end part of the inner ring, and the thickness of the flange along the axial direction of the inner ring is larger than the depth of the inner groove.

Specifically, the inner groove is formed at one end of the outer ring.

Specifically, the depth of the inner groove along the axial direction of the outer ring is 0.3-2 cm.

Specifically, the width of the inner groove along the radial direction of the outer ring is 0.5-2 cm.

Specifically, the rolling bodies are cylindrical rollers, tapered rollers or steel balls.

Specifically, the end parts of the inner ring and the outer ring are provided with sealing rings.

Specifically, an oil guide groove is arranged at the joint of the inner ring and the flange.

The utility model has the advantages that: a thrust bearing comprises an inner ring and an outer ring, wherein a rolling body and a retainer used for fixing the rolling body are arranged between the inner ring and the outer ring, an inner groove is formed in the inner side of the end part of the outer ring, a flange matched with the inner groove is arranged at the end part of the inner ring, and the thickness of the flange along the axial direction of the inner ring is larger than the depth of the inner groove. The flange of the outer ring is matched with the groove of the inner ring, so that the axial force borne by the thrust bearing is improved, and the thrust bearing is prevented from being scrapped or burned. The utility model relates to a rationally, convenient to use improves the life of bearing.

Detailed Description

The following detailed description of the present invention is provided in connection with the accompanying drawings and the embodiments, and is not intended to limit the scope of the invention.

As shown in fig. 1, 2 and 3, the thrust bearing of the present embodiment includes an inner ring 1 and an outer ring 2, a rolling element 3 and a cage 4 for fixing the rolling element 3 are disposed between the inner ring 1 and the outer ring 2, the rolling element 3 is a cylindrical roller, a tapered roller or a steel ball, an inner groove 21 is disposed inside an end portion of the outer ring 2, a flange 11 engaged with the inner groove 21 is disposed at an end portion of the inner ring 1, and a thickness of the flange 11 in an axial direction of the inner ring 1 is greater than a depth of the inner groove 21. When in use, the flange 11 of the inner ring 1 is matched with the inner groove 21, so that the inner ring 1 and the outer ring 2 can be prevented from relative displacement along the radial direction, the axial force of the thrust bearing can be improved, the phenomenon that the thrust bearing is scrapped or burned due to overlarge axial force is prevented, and the service life of the thrust bearing is prolonged

The inner groove 21 is formed at one end of the outer ring 2, and the bearing is a one-way thrust bearing, so that the thrust bearing is convenient to assemble.

The depth of the inner groove 21 along the axial direction of the outer ring 2 is 0.3-2 cm, the width of the inner groove 21 along the radial direction of the outer ring 1 is 0.5-2 cm, and the axial force borne by the thrust bearing is convenient to improve.

The end parts of the inner ring 1 and the outer ring 2 are provided with the sealing rings 5, so that the thrust bearing is convenient to seal, and impurities are prevented from entering the bearing to influence the service life of the bearing.

An oil guide groove 12 is formed at the joint of the inner ring 1 and the flange 11, so that lubrication of the thrust bearing is facilitated.

It should be finally noted that the above embodiments are only intended to illustrate the technical solutions of the present invention, and not to limit the scope of the present invention, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present invention can be modified or replaced with equivalents without departing from the spirit and scope of the technical solutions of the present invention.
