Novel nylon wheel structure

Abstract

The invention discloses a novel nylon wheel structure comprising a nylon wheel. The middle of the nylon wheel is equipped with a steel axle sleeve. The nylon wheel is clamped to the periphery of the steel axle sleeve in a sleeving manner. The outer circumferential surface of the steel axle sleeve tilts from the center to the two sides, and the outer diameter in the center of the outer circumferential surface of the steel axle sleeve is greater than that at the two sides. The outer circumferential surface of the steel axle sleeve is provided with concave holes. The nylon wheel and the steel axle sleeve are integrally molded by a centrifugal casting process. The core part of the steel axle sleeve is provided with an axle sleeve through hole, an axle is embedded into the axle sleeve through hole, and the periphery of the axle is sleeved with deep groove roller bearings which are clamped into the axle sleeve through hole through clamp rings. Through the structure design, the novel nylon wheel structure has the advantages of reasonable design, simple structure, convenient production and preparation and easy installation, deformation of the bearings is reduced effectively, the strength of nylon wheels is improved, the service life of nylon wheels and the reliability of products are increased effectively, and the failure rate of elevators in the running process is reduced effectively.

Description

technical field [0001] The invention relates to the technical field of elevator structures, in particular to a novel nylon wheel structure. Background technique [0002] In the existing elevator structure, the steering wheel used for steering is changed from cast iron to nylon due to cost considerations, but nylon steering wheel is inherently harder than cast iron, so in actual use, the service life of nylon wheel The average is about one and a half years. The reason for replacement is usually that the nylon wheel bearing is under long-term stress, and the nylon wheel is deformed and damaged. [0003] Therefore, how to solve the deformation of the nylon wheel bearing is actually the direction that various manufacturers are working hard to solve at present. Contents of the invention [0004] The purpose of the present invention is to provide a new type of nylon wheel structure in view of the deficiencies of the prior art. The new type of nylon wheel structure is reasonable...
