ZENTRIEREINRICHTUNG FUER MECHANISCHEN TASTKOPF

摘要

The mechanical-probe alignment device proposed has an entrainment device and two restoring devices which act on the entrainment device in opposite directions. The alignment device has only one stop for one restoring device, although the stop may be a multiple one, and the restoring device abutting the stop when at rest exerts, at least when it is near the position of rest, a restoring force which is twice that exerted by the other restoring device. The restoring devices can be springs or fluid pistons. The alignment device proposed is simple and wear-resistant and has no hysteresis error.
