Claims

[Scope of Claim for Utility Model Registration] (1) A synchronous rotation mechanism that transmits the rotation of the input shaft to the output shaft by a gear device and rotates the output shaft synchronously, and a rotation mechanism centered around one gear of the gear device. Equipped with a phase adjustment mechanism consisting of a planetary gear mechanism that revolves while rotating on its own axis, the rotation due to the rotational driving force input to the phase adjustment mechanism is applied to the above-mentioned central gear, and the rotation of the output shaft is adjusted in phase with respect to the input shaft. A synchronous rotation phase adjustment device for a printing press, which is characterized by being flexible. (2) The synchronous rotation mechanism includes a planetary gear provided at a predetermined radius position from the axis of a rotating body fixed to the input shaft and engaged with the central gear, and a gear at the end of the rotating shaft. A worm gear mechanism that engages with the worm gear mechanism, a gear that is integrally connected to a rotating body that is fixed to the worm gear mechanism and is rotatable with respect to an input shaft, and another gear that engages with this gear and has an output shaft. The phase adjustment mechanism comprises two planetary gear trains provided in a gearbox, a fixed sun gear engaged by one planetary gear train, and a fixed sun gear engaged by the other planetary gear train for phase adjustment. a worm gear mechanism that inputs rotational force from the outside, the last planetary gear of the other planetary gear train is arranged to engage with the center gear, and the worm gear mechanism of the phase adjustment mechanism According to claim 1, a rotational force for phase adjustment is applied to the central gear via the other planetary gear train, so that rotation of the output shaft can be freely adjusted in phase with respect to the input shaft. The synchronous rotational phase adjustment device for a printing press described above.
