Wear in Polymer Composite with Solid Lubricants for Cage of Cryogenic Ball Bearing

摘要

It was experimentally elucidate the mechanism of friction wear surface for the sliding and rolling contact movement in the cryogenic atmosphere, such as low temperature for the equipment and space for the machine element. To evaluate the properties of the solid lubricating cage, we should minimize the frictional wear of the contact surface at a low temperature condition.[1] Investigations of wear resistance of polymers with additives, using the cryogenic pin-on-disk apparatus has been carried out. Normal load, rotating speed and liquid nitrogen flow rate were considered variables in the cryogenic wear tests. The friction and the wear mechanisms are briefly reviewed. Various polymeric materials containing solid lubricants were investigated.
