Optimization of the process of working-in details of gear pumps connections after repair

Abstract

EN: Working-in of friction pairs is a mandatory technological process, which is of great importance for wear-resistant surfaces and, as a result, extending the service life of hydraulic transmissions. It is a complex process that takes place under the influence of a large number of different factors. The entire working-in process can be divided into three periods: - the first is characterized by increased initial wear (during this period, the quality of the surface of the friction pairs is optimized); - the second is characterized by a decrease in the amount of wear, a decrease in mechanical losses due to friction, strengthening of surfaces, geometric alignment of parts relative to each other; - the third is characterized by the stabilization of all the main indicators of axial-piston units: wear of parts, feed rate, mechanical losses, oil pressure, temperature, etc.
