The manner of obtaining the friction coefficient of the contact surface is not limited. Example (c): processing the contact surface of the workpiece, or sticking a specific felt. This friction is the self-damping of the oscillating mechanism. Therefore, on the premise of not influencing the transmission function of the printer, the reduction ratio of the gear set is not changed, and the damping adjustment mode comprises the following steps: 1. adjusting the helical angle of the helical gear to increase or decrease the axial force of the helical gear rotation; 2. and adjusting the surface treatment mode of the workpiece to increase or decrease the friction coefficient of the workpiece.
