ELEVATOR SYSTEM DESIGN INCLUDING A BELT ASSEMBLY WITH A VIBRATION AND NOISE REDUCING GROOVE CONFIGURATION

摘要

elevator system design is implemented as a belt having a plurality of elongated load bearing member, such as steel kodeugwa. The jacket includes a plurality of spaced grooves on at least one side of the belt. At least one of the size of the drive sheave in groove width, and the system is selected to be within the range of the ratio of groove width to sheave diameter selected. In one embodiment, the ratio is preferably smaller than about 0.05. In addition, the grooves at the edge of the sheave surface and the coupling groove on the belt meets jacket groove preferably includes a fillet.
