TOOTHED BELT, TIMING BELT PULLEY FOR TOOTHED BELT, TOOTHED BELT TRANSMISSION, TOOTHED BELT MANUFACTURING DEVICE, AND MANUFACTURE OF TOOTHED BELT

摘要

PROBLEM TO BE SOLVED: To provide a toothed belt, a timing belt pulley and a transmission device for its toothed belt capable of obtaining an enough performance endured to a high load even when the width of the belt is narrow, excellent in durability, and capable of extremely decreasing a noise when driving, and easily and cheaply manufacture the toothed belt.;SOLUTION: This belt is provided with a main body formed of thermoplastic elastormer having tensile strength of 15 MPa or more, elongation of 250% or more, and rubber hardness of 80 to 95, and core wires buried in the main body and having tensile elastic modules of 25,000 MPa or more, and tensile strength of 800 MPa or more. Belt teeth 11, 12 inclined mutually in the reverse direction from a nearly central part of the belt width direction toward both ends of a belt width are formed at predetermined pitch intervals. The teeth are connected to each other at a nearly central position in the belt width direction, and are formed so as to shift in the belt longitudinal direction at positions of both ends part in the belt width direction.;COPYRIGHT: (C)2000,JPO
