TRANSMISSION BELT BLOCK AND METHOD OF MANUFACTURING THEREOF

Japanese Patent JPS60252839

A

PURPOSE:To prevent the V-pulley contact sections of blocks which are superposed on and attached to an endless belt-like flexible hoop, from being damaged, by forming an infinite number of micro-pores in the contact surfaces of the blocks and by forming a wear-resistant layer on the surface of each pore. CONSTITUTION:An infinite number of concave and convex parts are formed in the V-pulley contact surfaces of blocks 20 which are superposed on and attached to an endless belt-like flexible hoop along the lengthwise direction thereof, and every contact surface of each block is subjected to a polishing process to form flat surfaces 30 and an infinite number of micro-pores 28 in every contact surface. Thereafter, ion-plating is applied to at least on the inner surface of each micro-pore to form a wear-resistant layer 32. Accordingly, a local high contact- pressure is eliminated between the V-groove wall surfaces of a V-pulley and the contact surface of each block and the abrasion of the latter is restrained, thereby it is possible to prevent the contact surface of each block from being damaged.
