Document Type and Number:
Japanese Patent JP6845053
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To suppress generation of vibration even if a large load is applied in a cam device structured to transmit rotation of a roller gear cam having a ball-screw-shaped structure to rotation of a turret with which multiple cam followers are disposed on a circumference.SOLUTION: A rotary device comprises a motor, a first roller gear cam, a turret and a second roller gear cam. The first roller gear cam is rotated by the motor and includes a first tapered rib. Multiple cam followers that are successively engaged with the first tapered rib by rotation of the first roller gear cam are provided in an outer periphery of the turret. The second roller gear cam includes a second tapered rib and is rotated by successively engaging the multiple cam followers that are provided in the turret, with the second tapered rib, thereby suppressing vibration of the turret at least.SELECTED DRAWING: Figure 1
