Latest Patents

Yamamoto holds a patent for a "Ball screw device and injection molding machine incorporating the same." This invention provides a ball screw device for linear movement, which moves a working body by utilizing a single of a plurality of ball screw shafts and ball screw nuts. In this device, multiple ball screw nuts are engaged threadedly with the same ball screw shaft. One of the ball screw nuts on each shaft is attached to the working body via a fixed flange, which may include a load sensor. The other ball screw nuts function as a fluid pressure supporting mechanism using a cylinder and a piston. The fluid pressure is controlled to ensure that the support force of the fluid pressure supporting mechanism matches the pushing force detected by the load sensor. This configuration allows for the even distribution of a large load across the ball screw nuts.
