  • Method, apparatus, and system for non-contact manual measurement of a wheel profile
    Patent number: 7715026
    Abstract: A method, apparatus and system for non-contact measurement of a railway wheel profile are disclosed herein. To measure the wheel profile, a laser having a distance displacement sensor and angular displacement sensor projects a beam of light onto the surface of a railway wheel to measure the wheel profile. In an alternate embodiment, a rail thickness measurement gauge is provided. In another alternate embodiment, a witness groove measurement gauge is provided.
    Type: Grant

  • Wheel profile inspection apparatus and method
    Patent number: 6909514
    Abstract: A method and system for measuring railroad wheels, where the wheels may be measured while mounted on railcars that are in motion. The method and system may be practiced by using one or more lasers or other light sources to illuminate portions of the surface of the railroad wheels, two or more of which may be substantially mutually orthogonal. By converting images of the illuminated portions to coordinates, wheel center position and diameter can be calculated, and once center position and diameter are calculated, wheel profile parameters such as flange height, flange width, and tread hollow can be calculated. The method and system produces accurate results at speeds up to at least 60 miles per hour.
