GRINDING AND BUFFING OF WORK SURFACES IN CRANKSHAFTS AND CAMS OF CAMSHAFTS BY ENDLESS DIAMOND BELT
Abstract and keywords
Abstract (English):
A technology and a tool for processing work surfaces in crankshafts and cams of camshafts by endless diamond belts are considered. The characteristics of endless diamond belts and their potentialities in assurance of roughness and efficiency at work surface grinding and polishing are shown. The purposefulness in assurance of an optimum curvilinear transverse section of cams in camshafts by grinding with endless belts is defined. It is shown, that it is possible to control a curvilinear profile of cams in camshafts at the expense of a belt width and a belt tension. It is based on a theoretical basis of the interaction of a rigid die (cam) with the elastic half-space (belt). An optimum curvilinearity of the transverse section of a cam ensures the increase of its life.
