Bearing retainer and machining technique thereof

Abstract

The invention discloses a bearing retainer and a machining technique thereof. The technique mainly comprises: blanking perimeter and height required by the retainer at a time, moulding all cage pocket structures of the retainer at a time, and punching all the cage pockets into concave cage beams provided with groove structures at a time; circling the retainer bracket with circling mould, and welding the butt ports of two ends of the circle to form an integral bearing retainer structure. The machined bearing retainer bracket is in the integral bearing retainer structure formed by manufacturinginner and outer ring beams, cage pockets, concave cage beams between adjacent cage pockets, and boundary beams for connecting the concave cage beams to the space between the inner and outer ring beams with the same mild steel plate through the previous technique so that the invention has the advantages of reducing accumulated technique deviations, improving precision and reliablity of products, solving the problem of high cost of material waste in conventional bearing machining technique, fully increasing the utility rate of material, and further improving the production efficiency of the bearing retainer.

Description

technical field [0001] The invention relates to a bearing cage, in particular to a cylindrical roller bearing cage and its processing technology. Background technique [0002] The bearing structure usually includes an inner ring, an outer ring, a cage and rolling elements. The function of the bearing cage is to guide and drive the rolling bodies to roll on the correct raceway; the bearing cage separates the rolling bodies at equal distances and distributes them evenly on the rolling elements. On the circumference of the track to prevent the rolling elements from colliding and rubbing against each other during work; the rolling element structure includes balls and cylindrical rollers, and the cylindrical roller bearing cage structure and technology in the usual cylindrical roller bearing technology can be divided into nylon Injection-molded cylindrical rollers and cast blue, brass or bar steel are cut and processed into a cylindrical shape, stamped copper cover plate or bar s...

AI Technical Summary

Problems solved by technology

[0003] The present invention is provided to solve the current situation that the existing bearing retainer is either greatly limited in bearing load capacity and operating temperature due to the nylon plastic structure, or the overall cost is relatively high due to the machining process retainer made of green brass material. A simple structure, simple processing process, full use of processing raw materials, improve processing efficiency, precision and pass rate, and can better improve the overall strength of the concave pocket beam structure, reduce the possibility of fracture of the bearing retainer, and can A bearing retainer that better provides the lubricity of the retainer and improves the working reliability of the retainer

[0006] It not only solves the poor quality problems caused by the use of nylon material structural retainers, such as poor strength, low operating temperature, and easy aging; it also maximizes the utilization rate of the low-carbon steel plate itself to avoid unnecessary waste of materials Cost, compared with the general process scheme that adopts the overall blanking, multiple stretching, bottom cutting, and forming scheme, it reduces the waste of material cost, avoids the core block waste generated by bottom cutting, improves production efficiency, and avoids After multiple stretches, there is a certain difference in the overall thickness of the entire plate thickness.
