Abstract: An adjustment stroke connection for a mechanical press includes an eccentric bushing disposed within a press connection member and an eccentric crankshaft member disposed within the eccentric bushing. A rotatable crankshaft is connected to the eccentric member. A mechanism is provided for connecting the eccentric bushing with the press connection member in a manner that prevents rotation therebetween and concurrently permits rotation of the eccentric member relative to the eccentric bushing. When the mechanism is activated, driving rotation of the crankshaft produces a press stroke adjustment. A torque actuator delivers equal driving torque to plural eccentric crankshaft members to enable minimization of relative bushing angle slip. Suitable control of the bushing angle and slide position crank angle during bushing expansion and contraction also minimizes relative bushing angle slip.

Abstract: The present invention relates to an apparatus and method for adjusting the stroke length of a slide in a press. A sleeve works as a fluid bearing in relation to a shaft. Upon applying pressure to the sleeve, the sleeve creates an interference fit with the shaft. Once the interference fit exists, the position of the shaft can be adjusted to change the stroke length of the slide in the press.

Abstract: A drive disk assembly for use in a press machine is segmented into a plurality of discrete drive disk segments each having a friction pad attached thereto. The segmented drive disk permits individual disk segments and friction pads to be removed after installation without disassembling the entire arrangement. The disk segments may grow thermally without causing the flex disk being utilized to shift axially or radially. A slot formed throughout the disk segment acts as an effective heat barrier to protect sensitive parts from undue thermal exposure.
