Latest Patents

Chihara's latest patents include a motor design that features a cup ring and a holding plate positioned on either side of a front bracket of a stator. This design effectively secures the outer ring of a front ball-bearing of the rotor, preventing creep between the bearing housing and the outer ring. The thickness of a bearing shim is meticulously adjusted to ensure that the distance between the end portion of a tube section of the cup ring and the first end face of the outer ring is less than 0.1 mm. Additionally, the holding plate is temporarily fixed to a designated spot on the motor shaft and then secured with a screw, allowing it to solidly contact the outer ring of the front ball bearing. Notably, the outer diameter of the motor shaft is designed to be smaller than the center hole of the holding plate, ensuring that the holding plate does not make contact with the motor shaft.

Another significant patent is for a geared motor that incorporates a spline on a hollow shaft. This design allows for direct coupling of a shaft to be driven by an external apparatus. The arrangement of screw blocks rotational torque, positioning the screw as far from the output shaft as possible. An anti-revolving function is also integrated into the housing surface, located at the farthest point from the output shaft, minimizing the force required for securing the geared motor.
