POSSIBILITY OF THE POSSIBILITY OF USING COMPOSITE MATERIALS IN THE PRODUCTION OF SLIDE BEARINGS

Abstract

Task of the submitted article is confirmation of a possibility of replacement of materials of bearings of sliding in couples of friction of internal combustion engines. For what service conditions of concrete couple of friction have been revealed, and values of various factors influencing operating conditions of bearings of sliding – radical and conrod necks of a bent shaft and working surfaces of radical and connecting rods are defined. On the basis of the obtained data the polymeric material conforming to all to the established requirements of ensuring highly effective work of such couples of friction has been picked up. Special attention has been paid to detection of advantages of polymeric material before traditionally used details from metal. Constant improvement of physic mechanical properties of composite polymeric materials, increase in their strength parameters, and the most important higher level of wear resistance in relation to metal details, provides a real possibility of carrying out experimental works on production of separate details or completely steam of friction from polymeric materials.
