THE EFFECTIVENESS OF ULTRASONIC NON-ABRASIVE SMOOTHING OF BEARING RINGS OF 1118-2902840 TYPE

Abstract

One of the main trends of modern scientific and technological progress is the development and implementation of innovative high-tech technological processes. (Purpose of the study) The research purpose is in studying the process of ultrasonic smoothing of the raceways surfaces of the bearing 1118-2902840 type, allowing a deeper understanding of the kinematics of this process, and proposing a way to increase its resource and product quality in general. (Materials and methods) Scientific research and design ideas are constantly developing, with the study of new processing methods and the introduction of advanced technologies, the quality of ball bearing products is improving. As a result of the conducted experimental studies, there was revealed a significant influence of the force on the formation of the raceway radius. The radius of the raceway profile increases with increasing impact force. (Results and discussion) Bench tests were carried out on samples of bearings of 1118-2902840 type. The actual value of the dynamic load capacity was revealed, amounting to more than 55400 newton (more than 100 percent), the actual value of the adjusted bearing life with ninety percent reliability was more than 419 hours (124 percent). The company, while improving the quality of products, receives economic benefits from an increase in output and sales of products, an increase in the selling price, and a reduction in product defects. The article presents equations for calculating additional profit, the annual economic effect of improving product quality, and the absolute efficiency coefficient of capital investments. (Conclusions) In modern conditions of a market economy, the problem of improving the quality of products and ensuring their competitiveness for the countries of the Eurasian Economic Union is becoming the most urgent.
