    摘要: A pair of stepping motors form the basis of a coarse-fine drive mechanism. A coarse stepping motor imparts rotational motion through a drive gear to a driven shaft, and a fine stepping motor imparts linear or axial motion to the same shaft by means of a cam. The driven shaft is part of a system which integrates the afore-mentioned rotational and axial motions in order to rapidly and accurately move and position a rack through a wide range of drive increments which is afforded by the presence of the coarse and fine drives.

    摘要: A coupling structure for a reversing mechanism of a printing press, having a fixed gear (18), a pivotable regulating gear (20), and a plurality of parallel tightening bolts (30) extending in a regularly spaced manner around a cylinder shaft (12) of the reversing mechanism. A one-way clutch (54) transmits limited tightening torque to the bolts (30) to hold gears (18) and (20) together in an engaged state, whereas in a release state, the bolts (30) are freely loosened. A center gear 56 having an internal gear (62) transmits torque to the one-way clutch from an external drive motor (80).

    摘要: A transmission device includes a central wheel, a satellite wheel, a drive element and a tension control device. The central wheel is disposed to rotate about a central wheel axle that is fixed in a first position. The satellite wheel has a satellite wheel axle, which is movable with the satellite wheel relative to the fixed position such that the satellite wheel does not rotate about the satellite wheel axle. The drive element, which has a first portion and a second portion, connects the central wheel and the satellite wheel. When the satellite wheel revolves in a first direction around the central wheel, the central wheel is induced to rotate in a second direction opposite the first direction. The tension control device is connected to the drive element and controls its tension to at least partially compensate for the induced rotation of the central wheel.

    摘要: Disclosed is a relative rotation transmitting apparatus comprising outer and inner coaxial shafts, main and sub drives, speed-reduction unit operatively connected both to the telescoped shafts and the main and sub drives with associated gear wheels, and a tool-carrier fixed to the fore-end of the outer shaft and having means for converting the rotation of the inner shaft about the longitudinal axis to the rotation about an axis perpendicular to the longitudinal axis and means for converting the rotation about the perpendicular axis to the linear feeding of a tool along the perpendicular axis, thereby permitting the tool to rotate and move radially.
