Unique bike of automatic transmission by Laura bearing ring drive and crutch bearing

摘要

The bicycle was developed as a bevel gear driven shaft power transmission system because it was intended to develop the bicycle from the chain co-ordinate transmission system to the non-coaxial type. It was developed for the first time in Japan in the 1936s, and although it has been many years, it has not been practically used.;As a result of my experiments in the development process, the bevel gear drive system ignored even if this a friction loss when driving a power source with an engine or a motor, but when using a bicycle that is operated by human power, The bicycle that goes to the manpower is difficult because it runs on the uphill road with very weak force.;In this development, we have experimented with Laura Bearing bundle as the roller friction of the chain roller bearings, and it proved that the friction loss is the same as that of the chain roller because it becomes a frictional friction.
