Method for preparing bearing retainer by using carbon fiber composite material

Abstract

The invention relates to a method for preparing a bearing retainer by using a carbon fiber composite material. The method is characterized in that: a bearing retainer is prepared from 10 to 20 percent of carbon fiber, 10 to 20 percent of polytetrafluoroethylene, 10 to 20 percent of graphite, and 40 to 70 percent of poly(ether-ether-ketone) through the processes such as material preparation, raw material pretreatment, mould design, mould temperature, forming temperature, injection pressure, holding pressure and time. The bearing retainer has the advantages of: 1, uniform color, no pore, 38 percent of crystallinity of the materials, and the optimum state of the products; and 2, high hydrolysis resistance, low water absorption, and superhigh performance of chemical attack resistance and radiation resistance. Therefore, the comprehensive performance of the bearing retainer material can be improved, and the continuously-improved requirements of the national high-tech engineering on the bearing are met.

Description

Making Bearing Cage with Carbon Fiber Composite Material technical field The invention relates to the field of bearing materials, in particular to a bearing cage made of carbon fiber composite material. Background technique Bearings are important transmission parts of machine tools and their machinery, which support the shaft and bear the load from the shaft. Rolling bearings in bearings are composed of outer rings, inner rings, balls and cages. The function of the inner ring is to cooperate with the shaft and rotate together with the shaft; the outer ring cooperates with the bearing seat to play a supporting role; the cage can evenly distribute the rolling elements, prevent the rolling elements from falling off, guide the rolling elements to rotate and lubricate : The rolling elements are evenly distributed between the inner ring and the outer ring by means of the cage, and their shape, size and quantity directly affect the service performance and life of the rolling be...

AI Technical Summary

Problems solved by technology

The traditional cage is stamped and formed by metal plate. Because its materials are similar, it is easy to cause affinity phenomenon. With the development of non-metallic industry, people use non-metallic materials to make cages. The use of these materials solves the problem that metal cages are the same metal. However, there are certain problems in its wear resistance, hydrolysis resistance and flame retardancy, and its processing performance and other indicators are not as good as steel

Therefore, it is not suitable for aerospace, military, electrical and electronic and medical fields
