Main Category :Machinery Sub Category :Machinery Leelananda Jayasuriya This is a gear box applicable to convert bi-directional motion in to uni direction. It is capable of operating at very high speed oscillations up to 3000 rpm. Also cable of operating at varying amplitudes to generate uni direction motion from a disturbed wave paterns. Therfore it can be operate to convert swings to rotary motion. Therefore applicable as a ocean wave power generator , and as an oscillations converter for internal combustion process. There is a tremendous amount of energy available with natural sources without being able to make use of it without having suitable device the turn in to usable mechanical power. This uni directional gear fulfill this gap.
