Title: Akira Takami: Innovator in Non-Circular Gear Technology
Introduction
Akira Takami is a prominent inventor based in Himeji, Japan. He has made significant contributions to the field of mechanical engineering, particularly in the development of non-circular gear systems. With a total of 12 patents to his name, Takami's work has paved the way for innovative applications in various mechanical devices.
Latest Patents
One of Takami's latest patents is for a non-circular gear pair. This invention comprises two non-circular gears that are engaged in such a way that the first intermeshing rotation part creates an intermeshing pitch curve. This curve allows the speed of rotation of one gear to change exponentially in relation to the other gear's speed. The second intermeshing rotation part extends between the start and end points of the first part, forming a pitch curve that allows for continuous changes in rotation speed and angular acceleration throughout both parts.
Another notable patent is a driving apparatus with a speed changer for bicycles. This apparatus utilizes a pair of non-circular gears to perform exponential function angular velocity modulation. It features a primary angular velocity modulating mechanism with a first non-circular gear fixed to a rotary shaft that receives driving power. The secondary mechanism includes a one-way clutch that generates driving power through a third non-circular gear. This innovative design allows for a continuous change in the angular velocity ratio of the rear wheel shaft relative to the pedal crank shaft, providing a stepless experience for cyclists.
