INDEPENDENT CLUTCH AND BRAKE FOR A PRESS

摘要

A conversion kit for an existing machine tool drive converts the machine tool drive from an air activated system to a hydraulically actuated system. The existing machine tool drive includes an air activated clutch and brake which are mechanically interlocked to simultaneously move the brake between an applied condition and a release condition and the clutch between a disengaged condition and an-engaged condition. The conversion kit replaces the air activated clutch and brake with a hydraulically activated clutch and an independent hydraulically actuated brake and separates the activation of these devices. The separation of the activation of these devices permits the designing of a specified amount of overlap into the assemblies.
