Description
Summary:The effect of friction parameters (contact stress and speed factor) on the total activation energy of the tribochemical conversions of greases in the rolling friction zone was simulated for singly packed rolling bearings. The limiting efficiencies of greases in vacuo and in air were determined on a five-ball friction machine and used to calculate their energies of activation. Lubricating materials were represented by various classes of liquid basic components of high-temperature and special greases. The possibility of applying greases under various operating conditions was considered in terms of the model obtained.
