Title:
DRIVING DEVICE
Document Type and Number:
Japanese Patent JP2016211593
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a driving device which improves vibration resistance of a power source by preventing resonance of a gear and a rotor.SOLUTION: A driving device 10 comprises a first input side gear 23, a first output side gear 24 and plate springs 41, 45 in addition to a motor 20, a cam shaft member 28, a drive cam 30, a control shaft member 60, a roller 54 and a support frame 51. The first input side gear 23 meshes with a rotor gear 22 connected to a rotor shaft 21 and is transmitted with driving torque. The first output side gear 24 is provided coaxially with the first input side gear 23, and output torque is transmitted to the cam shaft member 28 via intermediate gears 25, 26. The plate springs 41, 45 can transmit driving torque from the first input side gear 23 to the first output side gear 24 while generating drag torque. As the drag torque of the plate springs 41, 45 acts on a rotor 210 in a state that the control shaft member 60 is mechanically held, the first input side gear 23 and the rotor 210 are hardly resonated by vibration.SELECTED DRAWING: Figure 1
