Abstract
A method for synchronizing the sensor movements of a pitch an/or concentricity measuring device for gears, wherein the sensor enters into gaps between teeth on the rotating gear, the measurement is made and then the sensor is retracted until the next gap has appeared in front of the sensor. The sensor movement is synchronized with the rotary movement of the gear by utilizing the output signals from the sensor to provide a measurement of the rate of rotation of the gear at the onset of the period when it is being carried along and, under consideration of the known gear parameters, using this measurement to automatically calculate the waiting period during which the sensor must be held in its retracted position before the next gap will arrive. An apparatus for determining the rate of rotation by measuring the time required for the sensor to traverse a given path length and to then control the sensor movement on the basis of the waiting period calculated from the determined rate of rotation is also disclosed.
