THE CONTACT PROBLEM OF THE WEAR CAUSED BY MELTING OF THE BUSHING OF ASLIDING BEARING

The contact problem of the wear caused by the melting of a thin polyme r bushing of a sliding bearing is considered on the assumption that th e coefficient of friction is a function of temperature. The relation f or the critical speed of rotation of the shaft at which melting begins is obtained. Formulae for the basic parameters of the contact interac tion such as the residue of the bushing, the angle of contact and the contact pressure are also derived.
