摘要： In an elevator sheave for a flat belt, the optimum crown height is within a range of approximately 0.033 to about 0.003 times the width of the elevator rope. The optimum radius is in the range of about 16.67 to about 50.00 times the width of the elevator rope. Both the crown height (h) and the crown radius (rc) may be expressed as a function of belt width (Wb). The groove width (wg) is in the range of approximately 1.5 and 2.25 times the width of the belt (Wb). A circumferential surface roughness of about 1.0 to 3.0 is applied. A hard, thin surface coating can be applied to enhance durability while maintaining traction.

摘要： Fluid is detected within a protective encasement of an hydraulic cylinder of an elevator by applying a low pressure to the interior of the encasement and sensing for the presence of fluid as a result of the application of the low pressure. If fluid is detected, a greater pressure is applied within the protective encasement to eliminate the detected fluid. The protective encasement, which may be pressurized, has a pressure input port, an evacuation port, and an evacuation tube which attaches to the fluid evacuation port and extends to a region within the encasement below the bottom of the cylinder.

摘要： An elevator load bearing assembly (30) includes a jacket (34) having different portions comprising different polymer compositions. In a disclosed example, a plurality of tension members (32) are at least partially surrounded by a first portion (36) comprising a first polymer composition. A second portion (38) establishes at least one exterior surface (40) of the jacket (34) and comprises a second polymer composition. In one example, a surface-modifying agent is added to alter the composition of at least a portion of the jacket (34). In another example, co-extrusion techniques using different polymer compositions establish different portions of the jacket (34).

摘要： An elevator load bearing assembly includes a plurality of cords within a jacket. The cords are spaced from an exterior surface on the jacket such that the spacing remains generally constant along the length of the belt. The jacket has a smooth, uninterrupted exterior surface for contacting sheaves as the belt moves in the elevator system. A method of making the inventive belt assembly is disclosed. The inventive belt assembly minimizes the possibility for generating an annoying, audible sound and vibration during elevator operation.

摘要： A segmented elevator sheave assembly has independently variable shoulder and crowning elements for use with flexible flat ropes in an elevator system. This enables selection of high-traction surface finish and crowning for the sheave groove that contacts a belt, and of low-traction, smooth sheave groove shoulders having a low friction coefficient that may inadvertently contact the belt side surfaces. This configuration is more forgiving to angular misalignment of the sheave and reduces the likelihood of premature degradation of a flat flexible rope due side-surface scuffing along sheave groove shoulders.

摘要： An elevator guide system for flat rope tracking prevents the flat rope from hitting the shoulders on a rotating sheave to prevent premature degradation emitting objectionable sounds. The rope guide system includes one or more guide bodies having channels generally aligned with sheave grooves to which each block is adjacently positioned using a frame-mount. The guide bodies align the flat belt on entry into and exit from a sheave. The guide bodies may have a planar back surface, or a circular back surface, with the channel sidewalls disposed thereon and extending outwardly at right angles therefrom.

摘要： An exemplary vertically moveable elevator system component includes a top portion, a bottom portion and a plurality of vertically oriented side portions between the top and bottom portions. At least one of the side portions includes a roller guide support sheet. A first roller guide roller is supported by the sheet such that the first roller is at least partially disposed on a first side of the sheet and an axis of the first roller is generally parallel with the sheet. Second and third rollers are supported by the sheet such that the second and third rollers are on a second, oppositely facing side of the sheet. An axis of each of the second and third rollers is generally perpendicular to the axis of the first roller. The axis of each of the second and third roller remains in a fixed position relative to the sheet.
