Abstract

PURPOSE:To restrain generation of noise by providing the required number of holes connecting C-shaped space to the outside the side wall portion of the groove of a belt pulley fitted to a belt. CONSTITUTION:Large holes 6 are formed on the side wall portion 5 of the groove 2 of a belt pulley 1 at equal intervals and six small holes 7 are formed between adjacent holes 6. Every one of holes 6, 7 is provided to connect air columnar space 4 formed between the bottom of the groove 2 of the pulley 1 and a belt 3 to the outside so that it functions to weaken air column sound by destroying a stationary wave generated in the space 4 during revolution. Accordingly, the belt pulley is constructed very simply and the volume of noise can be remarkably reduced.
