Latest Patents
Iehisa's latest patents include advanced designs for ball screw apparatuses. The first patent describes a ball screw apparatus that features a screw shaft with a spiral ball screw groove, a nut member with a screw groove, and multiple balls. A smoothly continuous worked portion is formed at the screw groove's corner, allowing for a gradual reduction in distance between the screw grooves as the ball enters from the connecting way. This worked portion extends from the connecting way's end in a circumferential direction of the nut member.
The second patent also focuses on a ball screw apparatus, which consists of a screw shaft, a nut, and several balls. It includes a first helical groove on the screw shaft's outer surface and a second helical groove on the nut's inner surface. The design defines a rolling contact way for the balls, with a connecting way formed by a tube that connects different parts of the rolling contact way. This innovative design allows for an endlessly communicating circuit, where the balls are arranged in a continuous loop.
