Latest Patents

Ueyama holds a patent for an electric actuator, which includes an electric motor, a nut, and a screw shaft that is threadedly inserted through the nut. This design allows the screw shaft to advance and retreat effectively. The threads of the screw shaft feature two flanks and a crest portion that connects them. Grease is utilized as a lubricant, and a groove portion is cut out from the crest portion toward the root portion of the threads to hold the grease. Additionally, a tapered surface is formed at the groove portion side end of at least one of the two flanks. This tapered surface inclines away from the groove portion, effectively dragging the grease onto the threadedly engaged portion through a wedge effect. This innovative design promotes lubrication within the electric actuator.
