ABSTRACT:
A variable speed transmission mechanism that easily achieves multiple variable speed effect, smooth operation as well as to economize energy. The mechanism includes a pair of fly wheels being arranged in parallel. The fly wheels being respectively fixedly or movably turning around a support. At least one or more input devices and force output devices being respectively mounted at a radial position between the fly wheels, having two friction wheel assemblies for frictional transmission together with the fly wheels. When the input device driving fly wheels to rotate at a fixed speed, to change the position of the input device or output device form the outer rim of fly wheels to the center of fly wheels, the output device would carry unequal inertia eccentric force and the input power to the input device can be adjusted lower, whereby the output device may obtain smooth and unequal output speed and horsepower and expand the range of variable speed depending on the increment of diameter of fly wheel in order to offer extremely high value of utilization in the field of industry.
