    • Elevators operating in hoistways serving landings at different floor levels of multi-story buildings are each provided with a compensation or comp sheave engaged in the lower bight of the rope, at the lower end of the elevator hoistway, with all or most of the weight of the comp sheave and its bearings and support assembly being carried by the lower rope bight, providing traction and transmitting tension force to the rope. The comp sheave assembly may include a motor drive machine and brake, providing traction drive at the lower hoistway end, and the consequent tension control can replace the elevator's conventional counterweight. An adjustable comp sheave support assembly achieves tension adjustment in the rope, reducing rope tension when desired, and readily adjusting rope tension for quick releveling of the elevator to compensate for loading changes as they occur.
    • 电梯在多层楼的不同层面上的着陆用电梯各自分别设置有电梯井道下端处于绳索下部弯道处的补偿或轮辋,其全部或大部分重量 组合滑轮及其轴承和支撑组件由下绳索承载,提供牵引力并将张力传递到绳索。 组合滑轮组件可以包括电机驱动机器和制动器,在下部井道端提供牵引驱动,并且随后的张力控制可以替代电梯的常规配重。 可调节的皮带轮支撑组件实现绳索中的张力调节,在需要时减小绳索张力,并且容易地调节绳索张力,以便电梯的快速重新平整以补偿其发生时的载荷变化。

    • A governor for a moving device, such as an elevator, includes a primary assembly that generates a magnetic field and a secondary assembly extending through the generated magnetic field. The assemblies define a rotor and a stator that rotate at a relative speed that is proportional to the speed of the moving device. The stator is biased into a stationary position. If the relative rotational speed exceeds a predetermined limit, the bias on the stator is overcome by the interaction of the secondary assembly with the magnetic field. Movement of the stator away from the stationary position actuates an apparatus to prevent an overspeed condition of the moving device.
    • 用于诸如电梯的移动装置的调速器包括产生磁场的主组件和延伸穿过所产生的磁场的次组件。 组件限定了转子和定子,其以与移动装置的速度成比例的相对速度旋转。 定子被偏置到静止位置。 如果相对转速超过预定极限,则通过次级组件与磁场的相互作用来克服定子上的偏压。 定子远离固定位置的运动致动装置以防止移动装置的超速状况。
