Ultrasonic measurement of railway wheel hub–axle press-fit contact pressures

Last updated on 22 August 2014 3:05

Railway wheels are secured onto the axle by means of an interference fit. The wheel is either shrink fitted or press fitted onto a pre-lubricated axle, and the resulting interference fit induces a contact pressure at the interface.
