Abstract
A roller bearing cage made of high-precision macromolecule materials, belonging to the processing technical field of bearings, comprises a main body and positioning holes, wherein the positioning holes are uniformly distributed along the radial direction of the main body and used for positioning a rolling body; a PEEK (Polyether-ether-ketone) plastic layer is coated on the outer surface of the main body; and copper alloy layers are compounded on the inner surfaces of the positioning holes by adopting thermal spraying or cast technology. The roller bearing cage provided by the utility model has the benefits that the manufacturing cost is lowered, the work noises of the bearing are reduced, the abrasion resistance is enhanced, and the service life is prolonged.
Description
Technical fieldThe utility model relates to the roller bearing retainer that a kind of highi degree of accuracy macromolecular material is processed, and belongs to technical field of bearing processing.
Background techniqueBearing in use also consumes a large amount of lubricant oil, be to guarantee the normal use of bearing, and generally all supporting have a retainer; Retainer not only can prevent the collision between the bearing roller, and can the rolling element channeling conduct still be generated heat easily in the process of motion and wear and tear owing to bearing; Thereby can cause the fracture and the burn of retainer; Therefore not only require wear resistance good to retainer, impact toughness is strong, and requires good, the easy processing of thermal conductivity.Mostly the retainer that present stage uses is made, though can guarantee certain intensity, is corroded easily, easy to wear, and difficulty of processing is high.
Summary of the inventionIn view of the defective that prior art exists, the purpose of the utility model provides the roller bearing retainer that a kind of highi degree of accuracy macromolecular material is processed.
For realizing above-mentioned purpose; The technical solution that the utility model adopted is: the roller bearing retainer that a kind of highi degree of accuracy macromolecular material is processed; It comprises body; And, it is characterized in that: said external surface coating poly ether ether ketone plastic layer, the internal surface complex copper alloy-layer of said positioning hole along the positioning hole of radially evenly arranging that is used for the positioning and rolling body of body.
The thickness of said poly ether ether ketone plastic layer is 10 μ m-45 μ m.
Said body adopts casting carbon to combine steel ZG200-400 or ZG230-450 or aluminum alloy.
The roller bearing retainer that a kind of highi degree of accuracy macromolecular material is processed, its beneficial effect is: at positioning hole internal surface complex copper alloy, when reducing production costs, reduced the bearing working noise, made it antiwear property and strengthen, prolonged its working life.Be provided with the polyether-ether-ketone layer at this external surface since polyether-ether-ketone to have hardness low, friction factor is low; Anti-height is hot, and characteristics such as oil resistance can make it can reside in the surface of retainer for a long time; Prolong the working life of retainer, and can delay the wearing and tearing of bearing outside track.
