TRACTION AND SLIP AT HIGHER ROLLING SPEEDS

In order to investigate the relationship between traction and slip at higher rolling speeds, such as those encountered in wheel-rail contact, the authors have constructed a high-speed rolling machine. This paper deals with some results of experiments carried out under spindle oil and water lubrication on this machine. The traction coefficients for both spindle oil and water were found to increase with slip ratio linearly at first and then gradually rising to a maximum value. Thereafter, they decreased with slip in the case of spindle oil but remained almost constant in the case of water with increasing slip ratio below 2 or 3%. They seemed to reach maximum values with almost the same slip ratio regardless of rolling speed or contact pressure.
