Latest Patents

One of his latest patents is a reduction gear device that features a first and second reduction mechanism. The second mechanism includes a crankshaft, an external gear, and an internal gear. In this design, one of the internal gear and the external gear is fixed to a base part side member of a robot arm, while the other is fixed to an anterior end side member. The inner diameter of the internal gear ranges from 140 mm to 200 mm, and the torque transmitted to the anterior end side member is between 650 Nm and 1960 Nm. Additionally, the number of teeth on the internal gear is less than 40 times the difference in the number of teeth between the internal and external gears.

Another significant invention is the eccentrically oscillating speed reducer. This device includes a case with inner teeth and multiple crankshafts with outer teeth. The crankshafts are eccentrically moved and mesh with the inner teeth of the case. A carrier supports the crankshafts and rotates relative to the case. The cylindrical gear transmits power inputted to one crankshaft to the remaining crankshafts, and it is supported by sliding friction.
