    摘要: An elevator sheave (20) includes a belt guiding surface (26) having a surface profile along at least a portion of the belt guiding surface. The surface profile preferably is defined by an nth order polynomial equation where n is a number greater than 2. In one example, the reference point (40) is a central point along the width of the belt guiding surface (26). In one example, a central portion (42) of the surface profile preferably is aligned to be generally parallel with the central axis (34) of the sheave body. Some examples have curvilinear side portions (44, 46) between the central portion (42) and the edges (28, 30) of the sheave. Other examples also include second side portions (48, 50) that have linear profiles.

    摘要: An elevator system includes a magnetic guide that dampens vibration of a flat rope that move the car and counterweight up and down in the hoistway. The flat rope is guided through an opening in the magnetic guide between a pair of ferromagnetic flux concentrators having a set of teeth. The flux concentrators concentrate a centralizing magnetic flux that centers the ferromagnetic wires of the rope between each tooth. As the centralizing force acts on each ferromagnetic wire, the flat rope will be magnetically laterally centered within the opening of the magnetic guide and vibration of the flat rope is accordingly dampened. In one example implementation of this invention, the magnetic guide is slideably mounted on a slide assembly in response to rope migration. The slide assembly operates in combination with the magnetic guide at particular locations throughout the elevator drive system to restrain undesirable rope vibration and migration without contact between the guide system and rope and reduces undesirable frictional forces.
