Vehicle wheel`s contact surface evenness testing method for wheel manufacturing industry, involves transmitting light that comes through gap between contact surface and measuring plate, where gap depends on insufficient evenness of surface

摘要

The method involves placing a wheel (1) with its contact surface (1c) at an even measuring plate (3a), and transmitting light from a light source (3b). The light comes through a gap between the contact surface and the measuring plate, where the gap depends on insufficient evenness of the contact surface. Intensity of light is detected by a set of light sensors, and the light-intensity lying in a given local area over a preset threshold is a criterion for insufficient evenness of the contact surface of the wheel. An independent claim is also included for a device for implementing a contact surface evenness testing method.
