Abstract
A ball screw includes a load path and a non-load path defined between the screw shaft and the screw nut with the two ends of the non-load path respectively connected to the load path and a reflow channel of the return tube. The ball screw defines an imaginary horizontal plane and an imaginary sloping surface that are intersected with each other at the center axis of the screw shaft. The imaginary horizontal plane passes through the non-load path. The imaginary sloping surface passes through the junction between the non-load path and the load path. The imaginary sloping surface defines a negative included angle within 1˜3 degrees with respect to the imaginary horizontal plane to reduce the impact force rendered by each rolling member to the return tube, enhancing operational smoothness and reducing operational noise.
