Title:
Transmission belt
Document Type and Number:
Japanese Patent JP6209524
Kind Code:
B2
Abstract:
A power transmission belt is used by being wound around a flat pulley so that an outer peripheral surface thereof contacts with the flat pulley. A portion forming the outer peripheral surface is made of a rubber composition including an ethylene-α-olefin elastomer as a rubber component thereof. The dynamic viscoelasticity properties of the rubber composition in a belt length direction satisfy ((a loss tangent tan δ at a temperature of 25° C. and a dynamic strain of 3.0%)/(a storage elastic modulus E′ at a temperature of 25° C. and a dynamic strain 3.0%))×1000≦3.0 MPa−1, and (a storage elastic modulus E′ at a temperature of 25° C. and a dynamic strain of 1.0%)/(a storage elastic modulus E′ at a temperature of 25° C. and a dynamic strain of 3.0%)≦1.30.
