滚珠丝杠是一种将旋转运动转变为直线运动的机械装置,由精密滚珠丝杠轴、滚珠螺母及循环滚珠轴承组成,其中滚珠轴承通过滚珠的循环滚动,充当丝杠和螺母之间的接口。滚珠丝杠内部摩擦阻力低,能承受高推进负载。其公差等级高,非常适合高精度的应用。
精密滚珠丝杠不尽相同。无论是公制、英制还是微型滚珠丝杠,其性能和使用寿命取决于以下关键因素,包括:
我们深知,您或许没有时间去研究和查询零件号来寻找合适的滚珠丝杠设计。为此,Thomson开发出更强大的在线产品查找工具,可简化搜索和选型过程,助您快速找到合适的零件,获取报价和交货期,即刻完成产品选购——一站式服务。
Thomson Screw Product Engineer, Jeff Johnson, overviews the anatomy of ball screws, the installation of ball screws and reloading ball bearings into a tube return nut.
How to install a ball nut onto a screw from an arbor.
How to reload the bearings into a tube return ball nut. Often inch series Ball Nuts utilize tube returns.
Looking to replace worn ball screw assemblies but they don’t know what kind of assembly it is. This will help you identify your existing ball screw assembly.
How to reload the bearings into a button return ball nut. Often Metric ball nuts are button return ball nuts. But this technique can also be used on tube return ball nuts. For another option for loading tube return ball nuts see our video demonstrating how to load a tube return ball nut.

滚珠丝杠可将旋转运动转变为直线运动,反之亦然。滚珠丝杠由精密滚珠丝杠轴、滚珠螺母及循环滚珠轴承组成,其中滚珠轴承通过滚珠的循环滚动,充当丝杠和螺母之间的接口。丝杠受力分布在众多滚珠轴承上,使得每个滚珠的负载相对较低。又因为滚珠丝杠副使用滚动元件,所以摩擦系数也较低。
