摘要
An elevator system design incorporates a belt having a jacket coating a plurality of elongate load bearing members such as steel cords. The jacket includes a plurality of spaced grooves on at least one side of the belt. The width of the grooves and the size of at least the drive sheave in the system are selected so that a ratio of the groove width to the sheave diameter is within a selected range. In one example, the ratio preferably is less than about 0.05. The grooves also preferably include a fillet at the edges of the grooves where the grooves meet with the sheave-engaging surface on the belt jacket.
