However, this prior art cannot dynamically adjust the clearance between the guide wheel and the bearing when the operating temperature of the guide wheel changes, so it is difficult to ensure the normal operation of the bearing, which affects the quality and service life of the elevator
Moreover, this prior art cannot avoid the incompatibility problem of two different materials when the cast iron core wheel and nylon engineering plastics are integrally cast, that is, the two materials themselves are difficult to match together.

Abstract
The invention relates to a nylon rope wheel. The nylon rope wheel depends on the compound effect of a nylon monomer with plasticizers, light activated calcium carbonate, heavy calcium carbonate, chopped glass fiber and long glass fiber, adopts plasticizers to enhance the heat-resisting and lasting quality of the nylon rope wheel, adopts light activated calcium carbonate and heavy calcium carbonate as modified supplements to alter the processability of the nylon rope wheel, adopts high-strength long glass fiber and chopped glass fiber to preferably bear stress, so as to improve performances and indicators of the nylon rope wheel, in particular to remarkably improve the tensile strength. The invention further discloses a nylon rope wheel device and an assembling method, as well as an elevator adopting the nylon rope wheel device. The nylon rope wheel device is smoother and more reliable in operation and scientific and reasonable in structure, lowers the cost, improves the quality, saves space, can transfer high torques, lowers the press-fit requirement on the nylon rope wheel and a special bearing, and can be used as a guiding wheel for one or more arbitrary systems of an elevator car system, a counterweight system or a traction system.
Description
technical field [0001] The invention relates to a nylon sheave, a nylon sheave device, an assembly method and an elevator containing the sheave device. Background technique [0002] The traditional sheave of the elevator is generally made of cast steel or cast iron. The wheel and the bearing are press-fitted at room temperature or after the wheel is heated. After the tolerance design of the inner hole of the wheel assembly, the interference fit between the wheel and the outer ring of the bearing can be guaranteed. , to ensure the precision used. The bearing is then assembled with the shaft. Since the linear thermal expansion coefficients of the materials used for the wheel and the bearing are the same, it is ensured that in future use, the assembly relationship between the two will not change due to temperature changes in the use environment. Then the traction rope must be installed in the rope groove of the outer ring of the wheel. Since the wheel belongs to a metal pulle...
