Fan folded drive belt for a V pulley drive

摘要

A pulley and "V" belt drive arrangement has a flexible belt disposed to transmit drive forces between two spaced "V" groove pulleys. The flexible belt is constructed from a single fan-folded metal strip which is maintained in a continuous loop by one or more continuous metal bands. The bands are disposed in a U-shaped saddle or slot area formed in the fan-folded belt. The sidewalls of the saddle prevent lateral migration of the bands. The band length is sized to provide a compression load on the fan-folded belt to prevent longitudinal separation of the ends of the belt during torque transmission between the pulleys.
