BELT CONSTRUCTION, THE COMBINATION OF THE BELT CONSTRUCTION AND A PULLEY AND METHODS OF MAKING THE SAME

摘要

The combination of an endless power transmission belt construction and pulle y therefor, the belt construction, and methods of making the same are provided, the belt construction (20) having a n inner surface (22) defining a plurality of longitudinally disposed and alternately spaced apart like longitudinal projections (24) and longitudinal grooves (25) that are adapted to mesh with a ribbed surface (31) of a pulley (30), the inner surface (22) of the belt construction (20) being cogged and defining a plurality of transversely disposed and alternately spaced apart transverse projections (28) and transverse grooves (29), the transverse grooves each having a depth (40) that is approximately one-half of the depth (38) of the longitudinal grooves (25) and that is approximately one-fourth of the thickness (41) of the belt construction (20) .
