... counterbalancing as well. mechanical press mechanical press drives MECHANICAL PRESSES use a flywheel to store energy and a slider-crank mechanism to convert rotational motion to reciprocating linear motion. Due to the slider-crank design, these presses are stroke limited; that is, the bottom dead...

Suppose the command event being modeled in a fault tree is “Engine starter grinds against engine flywheel.” To satisfy that condition, the engine must be running, and the operator...

.... A radically different design, a high-velocity rotary-type shear, is seen schematically in Fig. 13.7 . In this machine, the energy is provided by a flywheel that carries an open-type moving blade. According to tooling arrangement, one or two billets per revolution can be obtained. With this shear, production...

... are used to store energy, similar to the flywheel in a mechanical press or capacitance in servo-drive presses. Accumulator-drive presses are favored if the press has long idle periods between cycles, or very large press capacities are required, on the order of 9,000 to 45,000 metric tons (10,000 to 50,000...
