Description

Technical Field

[0001] The present invention relates to the technical field of wear measurement of elevator traction wheels, and particularly to a wear measurement device for elevator traction wheels. Background Art

[0002] An elevator traction wheel usually consists of a rim, a hub and spokes. Rope grooves are formed on the rim for accommodating the traction steel wire rope. The shape and material of the rope grooves directly affect the friction force and the service life of the steel wire rope. Common types of rope grooves include semi-circular grooves, V-shaped grooves and semi-circular grooves with notches. During the use of the existing wheel grooves of elevator traction wheels, it is necessary to regularly check whether the surface of the wheel grooves is flat, and whether there are cracks or excessive wear. However, the existing staff use a measuring ruler for inspection, and check by the naked eye manually, there are the following problems: 1. The root area (depth about 5 - 10 mm) where the wheel groove contacts the steel wire rope is difficult for manual direct observation due to the narrow space, and it is easy to miss cracks or wear; 2. Microscopic deformation or fatigue cracks on the side surface of the wheel groove (the friction surface with the steel wire rope) are difficult to identify by the naked eye; 3. When measuring the depth of the wheel groove with a caliper or a depth gauge, due to the uneven surface of the wheel groove or improper operation, the error can reach ±0.2 mm, and long-term accumulation will lead to uneven steel wire rope tension or slipping risk. For this reason, we propose a wear measurement device for elevator traction wheels. Summary of the Invention
