摘　　要：高精度传动的滚动丝杆螺母采用了一种全新的滚动结构,不仅具有普通滚珠丝杆的特点,而且丝杆螺母副采用了普通T型丝杆和一种变形滚珠轴承相配合并进行了优化设计,滚动精密螺母螺杆副的啮合间隙趋近于零,在往复直线运动换向时消除了空行程,全部为滚动接触使摩擦阻力更小,有效消除了往复间隙,提高了运动定位精度和效率。与现有技术相比,该螺母加工简便,具有易于调整和维护特点,降低了能耗、成本,便于推广和应用,具有很好的应用前景。On the basis of Patent 2005100261765 ,a rolling screw-nut pairs which is suitable for high precision transmission is developed. Using ordinary T-screw thaft as pushing element, the design of the pair is optimized by a newly-constructed nut,a sort of transformed bearings, to match with the thaft. While possesses the excellency of common ball crews, the easy adjustable nut provides a near-zero, roiling contacts with the thaft, so effectively eliminates the to-and-fro gaps and minimizes the friction in them, improves the locating precision and efficiency in moving. Compared with current technology, the nut has a specialty of easy-making, easy-adjustable and good maintenance. It also lowers the energy consuming and costs, and finds a good path to be popularized and applied, with a bright future of application.
