專利摘要

A double nut ball screw capable of sensing preload includes a screw rod, two nuts, a connection key, multiple balls, a deformable annular platform having a U-shaped cross section with a bottom wall portion and two sidewall portions integrally connected with two opposite lateral sides of the bottom wall portion, and an annular force sensor mounted on the bottom wall portion of the deformable annular platform and located between the two sidewall portions. The deformable annular platform has a protruded portion located at the outer surface of the bottom wall portion opposite to the force sensor, and is disposed in the gap between the two nuts and wedged between two mating surfaces of the two nuts with the distal ends of the sidewall portions abutted against the mating surface of one nut and the protruded portion abutted against the mating surface of the other nut.
