  • Patent number: 5806641
    Abstract: 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.

  • Patent number: 5769187
    Abstract: A drive unit for driving a press uses a hydraulically actuated oil shear brake unit located on one side of a flywheel and a hydraulically actuated oil shear clutch unit located on the opposite side of the flywheel. The actuating assemblies for the oil shear brake unit and the oil shear clutch unit are supplied as complete assemblies which are secured to the brake housing and clutch housing, respectively, at the time of assembly of the units to the press. The actuation of the clutch unit and the brake unit occur simultaneously and from the same hydraulic pressure source such that the overlap between the two units is controllable from no overlap to a specified amount of overlap where the brake unit is applied simultaneously with the engagement of the clutch for a specified amount of time. The stroke acquired by the brake and clutch actuating assemblies can each be selected at the time of assembly by selecting the appropriate width for a plurality of spacers.

  • Patent number: 5360091
    Abstract: There is provided a clutch/brake unit having aligned input and output shafts, clutch disks partially immersed in oil carried by the input shaft, brake disks partially immersed in oil fixed to the housing, and two series of friction disks also partially immersed in oil each series of friction discs secured to the output shaft and each series engagable by separate DC voltage coils. A fan is provided which is rotatable with the input shaft to provide cooling air to the clutch/brake unit. The operation of the clutch/brake unit is controlled by a computer which controls the relationship of the output shafts speed in relation to time.

  • Patent number: 5285879
    Abstract: There is provided a two-speed drive unit for a motor drive, the motor drive having a housing and a main rotatable member. The two-speed drive unit comprises a two-speed drive housing secured to the motor drive housing and a secondary motor secured to the two-speed drive housing. The driveshaft of the secondary motor extends into the two-speed drive housing. The two-speed drive unit further comprises a gear train operably associated with both the secondary motor driveshaft and a clutch, the clutch being disposed between the gear train and the rotatable member of the main motor drive for engagement and disengagement of the gear train with the rotatable member of the main motor drive. The clutch is normally engaged by a plurality of coil springs and disengaged by the action of an AC voltage coil. Control means are provided which are capable of storing predetermined positions of the motor drive at which engagement or disengagement of the two-speed drive is desired.

  • Patent number: 5190129
    Abstract: A basic unit for driving a press is disclosed. The unit uses two hydraulic actuated oil shear brake/clutch units which are in coaxial nested relationship. The basic unit provides a core assembly which can easily be modified or adapted to be mated with any type of press drive. Once the unit has been mated to a press a continuous supply of filtered and cooled oil is provided. This supply of oil provides little or no wear on clutch plates as well as low heat generation.
