    摘要： The present invention discloses a tapered braking device for electric winches which disposes a section of gear shaft, a section of core shaft, a wedge shape support, braking plates, an elastic element, a wedge shape piece A, a wedge shape piece B, a braking clutch base and so on in a gear box of an electric winch. When a motor works, the section of core shaft of the motor can drive the braking clutch base and the wedge shape pieces A, B to rotate, until a gap is formed between the friction faces of the wedge shape support and the wedge shape piece B and the braking plates so that the braking action stops. When the motor suddenly stops, a heavy load lifted by a tight wire rope reel provides a reverse pulling force so that the wedge shape piece B produces a reverse thrust force to push the friction faces of the braking plates, so the braking effect is achieved quickly. Based on the braking plates with the double tapered faces, the present invention can increase the braking area and the braking force and achieve safe braking. Furthermore, worn parts concentrate in the braking plates, so it only needs to replace the braking plates made of friction materials, which can simplify maintenance, reduce the costs and ensure service life of the gear box.

    摘要翻译： 本发明公开了一种用于电动绞车的锥形制动装置，其配置齿轮轴的一部分，芯轴的一部分，楔形支撑件，制动板，弹性元件，楔形件A，楔形件B， 制动离合器基座等在电动绞盘的齿轮箱中。 当电动机工作时，电机的芯轴部分可以驱动制动离合器基座，并且楔形件A，B旋转，直到在楔形支撑件的摩擦面和楔形件B之间形成间隙 制动板使制动动作停止。 当马达突然停止时，由严格的钢丝绳卷轴提升的重载提供反向拉力，使得楔形件B产生反向推力以推动制动板的摩擦面，从而快速实现制动效果 。 基于具有双锥面的制动板，本发明可以增加制动面积和制动力，并实现安全制动。 此外，磨损部件集中在制动板上，因此只需要更换由摩擦材料制成的制动板，从而可以简化维护，降低成本并确保齿轮箱的使用寿命。

    摘要： An adjustable brake is provided that applies a braking force directly to an elevator sheave (28) over which a cable (26) suspends an elevator car (14) and a counterweight (16). The brake includes a pair of calipers (38,40) that apply a braking force to either longitudinal end (30,32) of the sheave. The brake is spring set and may be released using, for example, electromagnetic, hydraulic or pneumatic forces. The calipers are mounted to and movable along a rail (42) to enable adjustment of the location of the calipers. Further, the calipers are coupled together using one or more pins (52) and are movable along the pins to enable adjustment of spacing between the calipers. The brake is particularly adapted for use with existing elevators because the brake does not require modification to the existing elevator sheave.
