專利摘要

A ball screw capable of sensing a preload is formed of a nut having an internal thread surrounding an imaginary central axis, a screw inserted into the nut and having an external thread surrounding the imaginary central axis, and a plurality of balls are mounted between the internal and external threads in a way that the balls roll therebetween. A mounting hole having a mounting surface therein is formed in the nut. The mounting surface corresponds to the internal thread in a way that it is substantially perpendicular to the imaginary central axis. A force sensor is mounted to the mounting surface. The force sensor can directly sense the preload in real time, so it is uneasily adversely affected by any environmental factor to have more accurate sensing result relatively.
