Description
Technical Field
The utility model relates to the technical field of rolling bearings, in particular to a nylon retainer of a thrust cylindrical roller bearing with a steel skeleton.
Background
The thrust cylindrical roller bearing bears pure axial load, the seat ring is fixed during working, the shaft ring rotates, the roller rolls and rotates between the shaft ring and the seat ring and revolves around the axis of the bearing, the linear speed of the outer edge of the roller is larger than that of the inner edge of the roller during the rotation and revolution of the cylindrical roller, so that the rotation of the roller does not completely do pure rolling rotation between the shaft ring and the seat ring of the bearing, namely the roller and the shaft ring and the seat ring of the bearing do not purely roll friction, but sliding friction is more serious when the roller is closer to the inner diameter of the bearing, and the force exerted by the roller is larger than that exerted by the sliding friction force when the sliding friction force is larger than that of the rolling friction force, so that the inner diameter of the bearing retainer bears the force exerted by the roller and is more than that of the outer diameter, and the retainer is easy to wear and even break from the inner ring.
The existing thrust cylindrical roller bearing generally adopts a metal stamping type retainer and a turning type metal entity retainer, but the metal stamping type retainer and the turning type metal entity retainer have the problems of high processing difficulty, complex assembly, large mass, large noise of the assembled bearing and the like. Therefore, the nylon retainer with the steel skeleton for the thrust cylindrical roller bearing is provided to solve the problems that the existing nylon retainer is low in strength and easy to break in working.
Disclosure of Invention
The utility model aims to provide a nylon retainer of a thrust cylindrical roller bearing with a steel skeleton, which solves the problems in the prior art.
In order to achieve the above purpose, the present utility model provides the following technical solutions: the utility model provides a thrust cylindrical roller bearing nylon holder with steel skeleton, includes the bearing race, the top of bearing race is provided with the bearing pedestal collar, be provided with bearing nylon holder between bearing race and the bearing pedestal collar, be provided with cylindrical roller in the fenestra of bearing nylon holder, the inner circle of bearing nylon holder is provided with the steel skeleton.
Preferably, the bearing nylon retainer consists of a steel skeleton and glass fiber nylon, and the steel skeleton and the glass fiber nylon are combined into a whole.
Preferably, the steel skeleton is made of DC01 material, and the bearing nylon retainer is made of nylon 66 and 25% glass fiber material.
Compared with the prior art, the utility model has the beneficial effects that:
1. according to the nylon retainer for the thrust cylindrical roller bearing with the steel skeleton, the strength of the nylon retainer for the bearing is enhanced by injecting 25% of glass fiber nylon 66 on the stamping steel skeleton, so that the strength of the retainer is effectively improved, the nylon retainer is prevented from being failed in advance, the service life of the bearing is prolonged, and the problem that the nylon retainer is easy to break in low-strength work is solved.
2. This thrust cylindrical roller bearing nylon holder with steel skeleton, bearing nylon holder has certain elasticity, and a set of cylindrical roller can be installed very easily in the fenestra of holder from the holder terminal surface, forms holder, roller subassembly, and during operation cylindrical roller guide holder is rotatory, owing to have steel skeleton in the holder, can bear the power that acts on holder internal diameter department because of the roller skids, has solved the high complex problem of assembly of punching press formula holder and car formula metal entity holder processing degree of difficulty, the effectual bearing cost that has reduced has improved bearing life.

Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Referring to fig. 1-4, the present utility model provides a technical solution: the utility model provides a thrust cylindrical roller bearing nylon holder with steel skeleton, includes bearing race 01, the top of bearing race 01 is provided with bearing collar 02, be provided with bearing nylon holder 46 between bearing race 01 and the bearing collar 02, be provided with cylindrical roller 04 in the window hole of bearing nylon holder 46, the inner circle of bearing nylon holder 46 is provided with steel skeleton 03.
The bearing nylon retainer 46 is composed of a steel skeleton 03 and glass fiber nylon, and the steel skeleton 03 and the glass fiber nylon are combined into a whole.
In this embodiment, a ring-shaped steel skeleton 03 is embedded in the weakest part of the bearing nylon retainer 46, so that the steel skeleton 03 and the bearing nylon retainer 46 form a whole.
The steel skeleton 03 is made of DC01, and the bearing nylon retainer 46 is made of nylon 66 and 25% glass fiber materials.
In the embodiment, the bearing nylon retainer 46 is formed by combining a steel skeleton 03 with a DC01 material and nylon 66 with 25% glass fibers, and has a simple structure, so that the bearing nylon retainer 46 can be molded in one step, the strength of the bearing nylon retainer 46 is greatly improved, the self mass of the bearing nylon retainer 46 is reduced, and the noise of the bearing is greatly reduced.
