In this article, we propose a dual-servo micro-feed mechanism based on the motion synthesis principle. The motor-driven ball screw and motor-driven ball nut of two quasi-equal areas can realize a micro-feed mechanism. The rotary nut and ball screw pair is the key component of movement and force transmission, and their dynamic performance directly determines the precision of the micro-feed mechanism; therefore, the kinematic characteristics of the dual-driven ball screw mechanism should be investigated.

新型摩擦差动微进给机构的运动分析与仿真

在本文中，我们提出了一种基于运动合成原理的双伺服微进给机构。两个近似相等面积的电机驱动滚珠丝杠和电机驱动滚珠螺母可实现微进给机构。旋转螺母和滚珠丝杠副是运动和传力的关键部件，其动态性能直接决定微进给机构的精度；因此，需要研究双驱动滚珠丝杠机构的运动特性。
