循环滚珠轴套装置是一种直线运动的轴承,必须与圆柱轴一起使用,沿轴作直线运动。这类轴套主要适用于载荷不很重的运动件。由于摩擦系数很小,约为0.0011～0.0027(常用金属的滑动摩擦系数约为0.05～0.2),因此,推动轴套沿轴运动所要求的推力不大。循环滚珠轴套装置除轴以外,主要由三部分组成:内经淬火的轴套、导珠件以及滚珠。有几排滚珠(通常三排至六排)在轴套的内径和轴之间,沿着轴套运动的方向作
The recirculating ball bushing assembly is a linear motion bearing that must be used with a cylindrical shaft to move linearly along the shaft. This type of sleeve is mainly applied to the load is not heavy pieces of movement. As the friction coefficient is very small, about 0.0011 ~ 0.0027 (commonly used metal sliding friction coefficient of about 0.05 ~ 0.2), therefore, to promote axial movement of the sleeve required thrust is not. Circulating ball bushing device in addition to the shaft, mainly consists of three parts: within the quenched sleeve, ball guide and ball. There are a few rows of balls (usually three rows to six rows) between the inner diameter of the sleeve and the shaft, along the sleeve movement direction
