ABSTRACT:
The double-flank composite error tester contains at least one magnet by means of which an associated gear is brought into a predetermined, always identical rotary position and fixedly held in this position prior to being interengaged with the teeth of another gear. A sensor is positioned adjacent the circumference of the other gear opposite to the center of a tooth tip or of a tooth space of the other gear. The teeth data of the other gear are supplied to a pulse processor. The other gear is then rotated and pulses are generated by the sensor due to this rotation. The pulses are fed to the pulse processor which generates pulses for controlling rotary drive means on the basis of the pulses received from the sensor and the teeth data supplied to the pulse processor. Such controlling pulses correspond to a central position at which the one gear can be engaged with the other gear in a collision-free manner. Instead of the sensor a magnet can be used and then the pulse processor can be omitted. This automatically operating error tester can be installed at a transfer line. In such installation the measuring device merely must determine for each set of gear teeth whether a permissible tolerance is maintained with respect to the gear center distance. Using such error tester there can be simultaneously tested two sets of teeth at two gears, and for this purpose such gears are each engaged with a related gauging gear.
