用于电梯系统的滑轮
摘要：
一种带式电梯系统(10)包括井道(14)和电梯轿厢(12)，所述电梯轿厢(12)经由悬挂部件(16)而悬挂在所述井道(14)中并且可以沿着所述井道(14)驱动。所述悬挂部件(16)布设在多个滑轮(18)上。所述多个滑轮中的一滑轮(18)包括界定所述滑轮(18)的中心轴的轴杆(36)，所述滑轮(18)可以围绕所述中心轴旋转。滑轮外部部件(38)可操作地连接到所述轴杆(36)并且可以围绕所述中心轴旋转。所述滑轮外部部件(38)包括与所述悬挂部件(16)相互作用的滑轮外表面(44)。所述滑轮外部部件(38)是由模制塑料材料形成。
摘要（英）：

A belted elevator system (10) includes a hoistway (14) and an elevator car (12) suspended in the hoistway (14) via a suspension member (16) and drivable along the hoistway (14). The suspension member (16) is routed over a plurality of sheaves (18). A sheave (18) of the plurality of sheaves includes a shaft (36) defining a central axis of the sheave (18), the sheave (18) rotatable about the central axis. A sheave outer member (38) is operably connected to the shaft (36) and rotatable about the central axis. The sheave outer member (38) includes a sheave outer surface (44) interactive with the suspension member (16). The sheave outer member (38) is formed from a molded plastic material.
