A mechanical assembly applicable to convert bidirectional motion of an input shaft into unidirectional motion of an output shaft comprising input shaft, intermediate shaft and output shaft, wherein two sets of gearing arranged one after the other, in combination with ratchet and pawl mechanisms driven in opposite directions, with two opposing ratchet wheels fitted to input shaft, each accompanied by a gearwheel driven on bearings on the same shaft with protruded flanges integral to aforesaid gear wheel, carrying spring loaded pawls on flanges to engage with accompanied ratchet wheel. The output shaft is coupled to input shaft by aforesaid gearings, in which 1st gear fitted on input shaft meshes directly with 1st gearwheel fitted on output shaft to turns in clockwise direction only while 2nd gear fitted to input shaft couple the output shaft, by means of intermediate gear arrangement to reserve its direction. This sort of gear arrangement is suitable for wave power generation, internal combustion engine and many industrial applications as a separate gearing unit to convert oscillations in to rotation. |
