EVALUATION OF STRUCTURAL AND ENERGY PARAMETERS OF FRICTION PAIRS UNDER START – STOP MODE
Journal Title: Проблеми тертя та зношування - Year 2016, Vol 70, Issue
Abstract
The presented study identifies patterns that influence the kinetics of the formation of the boundary layers of lubricating mineral gear oil on activated friction contact surfaces, and the increment of the friction specific work on wear-resistant steel 40Х and ШХ15 in frequent start – stop operation mode. The analysis of the lubricating ability of oil at the starting maximum torque of friction showed that the thickness of the oil layer formed in contact has a dual nature – boundary and hydrodynamic. The differences are indentified in the increment of the friction specific work for steel brands under research in the start-up period at pure rolling as well in slippage presence, herewith, the energy intensity of contact is higher for steel 40Х. On kinetics of changes in the energy parameter for the researched steel brand is significantly affected by the structure of steel after quenching and tempering
