Abstract
An emergency drive belt and a method of forming the same are provided, wherein such method comprises the steps of winding a ribbon of a cured elastomeric material having a bonding medium on at least one side thereof around at least two spaced apart pulleys and continuing such winding until the belt is built up to a desired thickness.
Claims8
A drive belt comprising at least one ribbon of cured elastomeric material extending repeatedly along the length of said belt to form a plurality of layers with adjacent layers being bonded together with a bonding medium, wherein said cured elastomeric material has a tensile strength in the approximate range of 3,800 to 4,500 psi., a modulus of elasticity in the approximate range of 1,800 to 2,400 psi. at 200% elongation and a compression set of about 15 to 25%.
The method of forming an emergency drive belt which comprises the steps of providing a ribbon of cured elastomeric material having a bonding medium on at least one surface thereof and a protective layer of suitable material on the outer surface of said bonding medium, winding a first loop of said ribbon around at least two spaced apart pulleys, removing said protective layer, as necessary, to effect bonding of one the layers of elastomeric material to the next adjacent layer of elastomeric material, placing said first loop under tension, bonding the end of said ribbon to said first loop, thereby forming a first layer, and continuing said winding to a desired depth.
