A crank mechanism that utilizes the inner cycloid curve,
A unique device that eliminates vibration and mechanical losses from piston reciprocating motion from the original principle.
It is the culmination of 20 years of research and development.
The fully rotating balanced cylinder system eliminates mechanical losses caused by piston reciprocating motion in reciprocating systems.
By driving the crankshaft using the cycloid principle,
It enables a four-cylinder piston that moves in two directions.
This suppresses shaft shake and vibration, reducing low noise and energy waste.
Additionally, since the output size can be kept small, there are advantages in terms of size and weight.
Main Features
- Eliminates center of gravity with three levels of balance adjustment (individual piston → second crankshaft → all moving parts)
- Physically converts the piston’s reciprocating motion into uniform rotational motion, reducing mechanical losses.
- Notable effectiveness in high-speed rotation areas
- Structurally, it inevitably enables miniaturization and weight reduction
