Impact of Turning Operations on the Formation of Rolling Bearing’s Functional Surfaces

Abstract

Under the conditions of operation of high-speed rotor mechanisms, bearing bearings become the primary source of unwanted vibrations, noise, and premature loss of the initial operational properties of the machines. Accordingly, the requirements for the quality of rolling bearings and their performance are constantly growing, and the technological support of the regulated requirements is becoming increasingly problematic. To increase the efficiency of machining operations of bearing parts and ensure the required quality of functional surfaces of rings in automated production, it is necessary to develop new effective methods of design and control of technological processes for the manufacture of individual bearing parts. The article analyzes the principles of technological support of quality parameters of the functional surfaces of the rings to improve and stabilize the performance of roller bearings. The reasons for increasing the vibroactivity of the working surfaces of the rings and the excess of the allowable vibration parameters and bearing noise are investigated. The connections of technological factors of forming operations of turning processing with parameters of microgeometry of the processed surfaces and operational properties of bearings are established. Models of formation of microgeometry of rotation surfaces on turning operations are developed, the reasons and technological features of formation of undulations on the processed surface are revealed.
