    摘要: Damping apparatus within an actuator device in which a backstop is supported on one portion of a dual cantilever (38) to match the movement of the impacting actuator to reduce wear and provide positive restoration of initial position, wherein the backstop-supporting cantilever portion is embedded in energy-absorbing elastomeric material (60) that is symmetrically confined to shorten settling time of the actuator and remain unaffected by temperature changes.

    摘要: The disclosure describes a passive lubrication system for use in a high speed print hammer mechanism (10) to provide continuous lubrication to all print hammer elements (12). Channels (22, 23) are formed along the length of a pivot pin (17) and filled with a porous material (24, 25) having a finer porosity than the sintered print hammer block (21) serving as the principal reservoir. Fins (11, 13, 14) located at each side of print hammer elements (12) also are of the same porosity as the print hammer block and communicate lubricant to the material (24, 25) in the pivot pin channels (22, 23). From the channels, lubricant is conveyed to the interface between each print hammer element (12) and the pivot pin by capillary action.

    摘要: Damping apparatus for minimizing print hammer settle time permits an increase in the hammer repetition rate, and in which the damping element (34) is a reactive mass which is freely movable behind the actuated element (10) to effect one or more energy transfer collisions with the actuated element. A return spring (25) applies a return force to restore the actuated element (10) and the reactive mass (34) to a rest position. A bias spring (39), having an applied spring force which is lower than the return spring (25) moves the re­active mass (34) at a slower rate than the actuated element (10) to cause the actuated element (10) to collide with the reactive mass (34) in advance of the rest position whereby the rebound energy of the actuated element (10) is dissipated and restoration of the actuated element (10) can occur as a result of the restore force applied by the return spring (25). In one embodiment, the reactive mass (34) comprises a backstop assembly movable from the rest position by a spring and comprises a pair of relatively movable damping masses (50,60) coupled by resilient energy absorbing material.
