Apparatus and method for measuring runout

摘要

A method and apparatus for measuring runout of using a distance measuring sensor mounted to a rotor and targeted at a circular wall, an electronic inclinometer mounted within a diameter of a hub of the rotor, and a microcontroller in data communication with the inclinometer and the sensor. A computer may be operably connected to the microcontroller and used for programming the microcontroller. A rotatable fixture including a bar mounted to the hub may be used to mount the sensor to a distal end of the bar and the microcontroller and the inclinometer may be mounted on the bar. Runout of a fan shroud circumscribing fan blades of an engine rotor may be measured with the apparatus and method and the bar angularly located between a pair of adjacent blades. The computer may be used to gather data from inclinometer and sensor and calculate runout.
