摘要: 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 can be 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.

摘要: A two-speed press drive is manufactured as a complete assembly eliminating the requirement that the drive be assembled at the location of the press. The two-speed drive includes a stationary quill, an output shaft and a planetary gear set. The planetary gear set includes a first sun gear connected to the stationary quill, a second sun gear rotatably connected to the stationary quill, a planetary gear carrier rotatably connected to the stationary quill and three compound planetary gears rotatably connected to the carrier and meshing with both the first and second sun gears. The input to the two-speed drive is through the planetary gear carrier. A high speed clutch connects the carrier directly to the output shaft for high speed operation. A low speed clutch connects the second sun gear to the output shaft for high speed operation. A housing in conjunction with the carrier define a sealed cavity within which the components of the drive operate.

摘要: A drive unit for driving a press is disclosed. The drive unit 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 if the flywheel. The brake is normally biased into its applied condition and the clutch is normally biased into its disengaged position. The engagement of the clutch and the release of the brake occur from the same hydraulic pressure source. The amount of overlap between the two units is accurately controlled by varying the biasing loads of the assemblies and accurately setting the stroke of the actuation member for each assembly.

摘要: A press includes a drive system which includes a brake and a clutch operated by fluid pressure. The brake and clutch control the movement of a crankshaft in relation to a flywheel. A unique control system supplies the pressurized fluid for operation of the brake and clutch. The unique control system includes a pressure relief valve for defining a maximum fluid pressure and a plurality of valve modules which each define a specific fluid pressure. Each valve module is selectively movable between a relief condition and a blocked condition. Thus, by selectively operating the valve modules, it is possible to select the fluid pressure being supplied to the brake and clutch.

摘要: A drive unit for a press uses an oil shear brake unit and an oil shear clutch unit. The actuation of the brake unit and the clutch unit occurs simultaneously due to a common activation member. The oil cooling system for the drive unit feeds oil to the outer radial or circumferential portion of the drive and returns oil for the central portion of the drive. The reverse flow of oil provides a more consistent supply of cooling oil to remove heat and lubricate the various components of the drive unit to significantly improve the operating performance of the drive.

摘要: A control system for a press having a clutch and a brake includes a clutch control valve and a brake control valve. The clutch control valve operates the clutch by supplying pressurized air to the clutch. The brake control valve operates the brake by supplying pressurized hydraulic fluid to the brake. The brake control valve is activated by pressurized fluid from the clutch control valve in order to insure simultaneous release of the brake with engagement of the clutch as well as simultaneous application of the brake with disengagement of the clutch.

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.
