Title: John Robert Colbourne: Innovator in Gear Systems and Clutch Technology
Introduction
John Robert Colbourne is a notable inventor based in St. Albert, Canada. He has made significant contributions to the field of mechanical engineering, particularly in gear systems and clutch technology. With a total of 6 patents to his name, Colbourne's work showcases his innovative approach to solving complex engineering challenges.
Latest Patents
Colbourne's latest patents include groundbreaking inventions such as the "Conjugate Gears with Continuous Tooth Flank Contact." This gear system features gears with a tooth flank profile that includes a convex addendum and a concave dedendum. When these gears mesh, they satisfy the Euler Savory equation for conjugacy, ensuring unbroken lines of contact across the entire tooth flank. The design incorporates an involute or other geometric curve between the addendum and dedendum.
Another significant invention is his clutch device, which achieves torque modulation and speed trimming by manipulating only a fraction of the torque transferred over a wider speed range. This clutching device utilizes a planetary gear set connected to a prime mover, featuring a ring gear, a planet carrier with at least one planet, and a sun gear. The device allows for controlled speed modulation between the prime mover and the output device, with energy recoverable by the modulating device.
