Abstract
The invention relates to a novel cage structure for a cylindrical roller bearing and belongs to the technical field of bearings. The novel cage structure for the cylindrical roller bearing comprises two cage washers, a plurality of hexagon socket head cap screws and a plurality of connecting parts, wherein, a cylindrical rolling element is provided with a blind via hole on each an end face; the hexagon socket head cap screw which is fixed on the cage washer is connected with the cylindrical rolling element by the screw head inserted in the blind via hole so that the cylindrical rolling elements are retained separate in a circle; the two cage washers are connected together as a whole body by the plurality of connecting parts. The new-type cage structure provided by the invention has the characteristics of being convenient to manufacture and assemble with a low total weight, thus being of good economic benefit and practical value.
Description
Technical field
The present invention relates to a kind of novel cylinder roller bearing retainer structure, belong to technical field of bearings.
Background technique
Retainer plays a part circumferencial direction and separates rolling element in bearing.In use, because the moment impact load is bigger, sliding friction and action of centrifugal force cause retainer distortion or fracture through regular meeting in addition, cause bearing wear to be scrapped, and can not normally use.The retainer that generally uses generally all is to come the relative fixed roller by axial bore now, and use closing-up, this retainer processed complex, the assembling trouble, and because the intensity of retainer is not high, cause bearing drawbacks such as running is unusual, fracture often to occur, can not satisfy the bigger occasion of impact load.
Summary of the invention
In view of the defective that prior art exists, the purpose of this invention is to provide that a kind of oeverall quality is light, roller quantity is many, processing and novel cylinder roller bearing retainer structure easy to assembly.
For achieving the above object, the technical solution adopted in the present invention is: novel cylinder roller bearing retainer structure, form by two retainer packing rings, hexagon socket cap head screw and connection sets, cylindrical rolling element end face digs blind hole, realize cylindrical rolling element circumferencial direction is separated in cylindrical rolling element end face blind hole by the hexagon socket cap head screw head that is connected on the retainer packing ring, two retainer packing rings become one by the connection set connection.
The present invention is compared with prior art, and is more than conventional window body structure retainer dress rolling element quantity, more less slightly than perforating branches columniation structure retainer roller quantity, but the hollow roller that the perforating branches post must be made with the big steel for carburizing of cost.Cylindrical rolling element end face digs blind hole can improve roller and raceway distribution of contact situation, this kind retainer has processing and characteristics such as easy to assembly, and the retainer overall weight is light, the structural strength height, so the improvement of this kind retainer has very big economic benefit and use value.
