长跨距滚珠丝杠辅助支撑装置

Auxiliary sustaining device for long span ballscrew

介绍了一种数控机床长跨距滚珠丝杠使用的辅助支撑装置,该辅助支撑装置是一种可以与滚珠丝杠螺母一起随动的动态滚珠丝杠辅助支撑装置,它能有效解决长跨距滚珠丝杠自重下垂变形以及旋转抖动问题,延长了长跨距滚珠丝杠及其支撑轴承的使用寿命,提高了机床运动精度和加工精度,降低了机床运动噪声。

This auxiliary sustaining device is a dynamic assistant supporting system that follow-up with the motion of ball screw nut and this unique system could eliminate effectively swing quiver and gravity sag of long span ball screw system. This innovate not only improves dramatically the life span of supporting bearings and the life span of long span ball screw, but also improves the motion ＆ machining accuracies ＆ lowers down the noisy level of the working machine.
