Abstract
Method and apparatus () for measuring a manufacturing deviation in an external gear (). The gear is arranged onto a stationary central pin (), the external diameter of which is smaller than the internal diameter of the gear so that a relative movement between the gear and the pin is allowed; a coupling member (), preferably including a head () that does not rotate and is adapted to fit into the teeth of the gear, is urged with a predetermined strength against the teeth of the gear in order to mesh with the teeth and concurrently bring an internal lateral surface of the gear into engagement with an external lateral surface of the pin. The position of the central axis (A) of the gear is determined and the manufacturing deviation of the gear is determined as a function of said position. The deviation so determined can be corrected as a function of a reference distance (D) indicative of the radial dimensions of the gear.
