摘要：

Crosshead sheave, installed on the top of elevator car, plays a role to transfer traction force from the steel wire ropes to the car. The common manufacture method for sheave is casting and then machining. However, casting sheave is heavy and needs the large amount of subsequent machining. In addition, heavy sheave induces more energy wasting in elevator operation. In recent years, the green elevator, the energy-saving elevator and intelligent elevator become the development trends of elevator. Therefore, a new type of crosshead sheave, shell-structure sheave is put forward in this paper. Shell-structure sheave, with less weight, high stiffness and high manufacturing precision, is manufactured by sheet metal stamping and spinning process. In this paper, the structure of shell1 sheave is designed. The force, applied on the sheave by steel wire ropes, is analyzed by using commercial FE software ABAQUS/Standard. DYNAFORM, commercial FE software for sheet metal forming process, is used to analyze the drawing process, and flanging process. In order to investigate the metal flow in spinning process, FORGE 2D is used to simulate this process. Then reasonable spinning parameters are obtained. Results show that the shell sheave has well formability and it can be a suitable choice to replace the casting sheave.
