More Information
Summary:A ball screw shaft capable of monitoring twisting force in real time includes a screw shaft, a screw nut mounted to the screw shaft, and a plurality of rolling balls arranged between the screw shaft and the screw nut. A twisting force sensor has a first fixing terminal surface and a second fixing terminal surface. The first and second fixing terminal surfaces of the twisting force sensor are fixed to a working platform and the screw nut, respectively, so that the twisting force sensor is capable of directly sensing the magnitude of the twisting force when the screw nut drives the working platform to move. As a result, by monitoring the voltage value outputted from the twisting force sensor, it is possible to monitor the twisting force value of the screw shaft during operation in real time, thereby achieving the purpose of the present invention.
