More Information
Summary:An elevator system includes an elevator car, a motor, and traction sheave operably connected to the motor to drive rotation of the traction sheave. A belt is operably connected to the elevator car and in frictional contact with the traction sheave to urge movement of the elevator car. One or more deflector sheaves are located between the traction sheave and the elevator car over which the belt is routed to guide the belt to the elevator car. The one or more deflector sheaves include an outer sheave surface having a distance from a sheave axis that varies along a width of the traction sheave. The outer surface includes a first portion having a first coefficient of friction and a second portion having a second coefficient of friction less than the first coefficient of friction, the first portion guiding an elevator belt toward a lateral center of the outer surface. 种电梯系统包括电梯轿厢、电动机以及牵引绳轮，所述牵引绳轮可操作地连接至所述电动机以驱动所述牵引绳轮的转动。皮带可操作地连接至所述电梯轿厢并且与所述牵引绳轮呈摩擦接触以迫使所述电梯轿厢移动。个或多个导向绳轮位于所述牵引绳轮与所述电梯轿厢之间，经由所述个或多个导向绳轮运送所述皮带以将所述皮带引导至所
