Vibration reduction structure for ball screw pair

The invention provides a vibration reduction structure for a ball screw pair, and belongs to the technical field of damper vibration attenuation. The vibration reduction structure comprises the ball screw pair and damper units. A screw rod of the ball screw pair is a hollow screw rod, wherein the multiple damper units are distributed inside a cavity of the screw rod. Each damper unit is composed of a mass block, rubber rings and adjusting nuts. The two ends of each mass block are provided with the corresponding rubber rings which are fastened through the corresponding adjusting nuts. The mass block of each damper unit is fixed in one inner hole of the hollow screw rod in a supported mode through the corresponding rubber rings at the two ends, the supporting stiffness on each mass block by the corresponding rubber ring is changed through the adjusting nuts, as a result, the inherent frequency of all dampers is matched with the dynamic property of the ball screw pair, and the optimal vibration control effect ca
