由英国工程和科学器件公司向国内介绍的瑞士制造的卫星丝杆是采用循环滚珠丝杆的原理设计的。它与滚珠丝杆的主要区别是在螺母中用一些小的螺纹轴来替代循环滚珠或滚柱,这些螺纹轴与主丝杆啮合,通过多点接触传递力,它们在螺母中如行星般地围绕地球随着主丝杆转动。这种设计所提供的优益是:负载能力明显增强:丝杆既可高速运转,又能保且维持小的摩擦系数。其次,螺母能单独从丝杆折卸而无需松开其它构件,易于更换。
The Swiss-made satellite screw introduced to the country by British engineering and scientific device companies is based on the principle of a recirculating ball screw. The main difference between a ball screw and a ball screw is the replacement of a recirculating ball or roller in the nut with small threaded shafts that mesh with the main screw rod and transmit the force through multiple points of contact, Around the earth with the main screw rotation. The benefits of this design are: Significantly increased load capacity: the screw can run at high speeds while maintaining a low coefficient of friction. Secondly, the nut can be detached from the screw alone without loosening other components, easy to replace.
