A Tool that Forms the Optimal Properties of the Surfaces of Sliding Contacts of Electrical Machines

The formation of the optimal properties of the surfaces of sliding contacts of electrical machines is extremely important. The solution to this problem provides an increase in the durability and operational reliability of modern machines. To the greatest extent, this applies to electric machines and electric vehicles, the operation of which is associated with the use of high-current sliding contacts. Brush-collector and brush-slip ring are two modifications of the sliding contacts of electrical machines. The integrated use of scientific and design and technical solutions makes it possible to provide a given resource for sliding contacts brush-slip ring. Electrodynamic processes, friction and wear processes to the greatest extent affect the operational reliability of the collector-slip ring assembly. Improving the design, the optimal choice of materials and the method of forming the surface layer are the main directions for ensuring a given resource of electrical machines. The latter is ensured by forming the optimal quality of the surfaces and material properties of the wear elements of the structure. To solve these problems, target functions and the structure of physical processes are formed. In addition, a relationship has been established between controlled and uncontrolled parameters. The defining parameters and response parameters are taken into account. This made it possible to formulate specifications for the design and development of a tool for finishing friction surfaces. The developed tool combines a combination of impact and friction processes on the surface being machined.
