Abstract
The present invention relates to a wrapped V-belt containing: a belt main body containing a compression layer containing a compression rubber layer and a fabric-laminated body layer, a tension rubber layer and a tension member buried between the compression layer and the tension rubber layer; and an outside cloth that covers a periphery of the belt main body, in which the compression layer has a plurality of notch portions not covered with the outside cloth, and the notch portion has a top disposed in the fabric-laminated body layer.
Claims11
A wrapped V-belt that is made to travel while a belt inner surface side thereof is wound around a pulley, comprising:
- a belt main body comprising
- a compression layer disposed on the belt inner surface side and comprising a compression rubber layer and a fabric-laminated body layer in which a plurality of pieces of a rubber composition-attached fabric are laminated and adhered to each other,
- a tension rubber layer disposed on a belt outer surface side, and
- a tension member buried between the compression layer and the tension rubber layer, and
- having a V shape with a width on the belt inner surface side being smaller than a width on the belt outer surface side on a section in a belt width direction;
- and
- an outside cloth that covers a periphery of the belt main body over an entire length in a belt circumferential direction,
- wherein the compression layer has a plurality of notch portions formed to extend in the belt width direction to be open on the belt inner surface side, are disposed to be aligned in the belt circumferential direction, and are not covered with the outside cloth, and
- wherein the notch portion has a top positioned on the most belt outer surface side in a belt thickness direction and disposed in the fabric-laminated body layer.
A method for manufacturing a wrapped V-belt comprises:
- a step of preparing a wrapped V-belt comprising:
- a belt main body comprising a compression layer disposed on a belt inner surface side and comprising a compression rubber layer and a fabric-laminated body layer in which a plurality of pieces of a rubber composition-attached fabric are laminated and adhered to each other, tension member and tension rubber layer disposed on a belt outer surface side;
- and
- an outside cloth that covers a periphery of the belt main body over an entire length in a belt circumferential direction;
- and
- a step of forming notch portions formed to extend in a belt width direction to be open on the belt inner surface side of the compression layer and disposed to be aligned in the belt circumferential direction such that a top positioned on the most belt outer surface side in a belt thickness direction is disposed in the fabric-laminated body layer, with respect to the wrapped V-belt.
