PROCESSES AND DEVICES FOR PRESSING OF GRAPHITOPLAST BLANKS FOR ELECTRIC BRUSHES REINFORCED AND NOT REINFORCED WITH CURRENT-CONDUCTING WIRES
The article is devoted to processes and equipment for the production of non-reinforced brushes and reinforced with a contact wire. The shortcomings of the block molding technology of brushes are shown: high labor intensity of the process, low productivity, long duration of operations in the manufacture of brushes, high demand for various devices and equipment for machining, including diamond equipment, and a laborious and inefficient operation for providing brushes with current leads. Finished products receive insufficient density and reduced physical and mechanical properties. As a solution to these problems, the improved patented methods for the manufacture of brushes for electric machines, the device for their pressing, developed by the scientists of SUSU are given, and the phenomena that occur in the implementation of these methods are described.
