Above-mentioned power plant are motor or diesel engine or petrol engine or water conservancy machine or wind energy conversion system or manpower machine.
The long end of the lever of two above-mentioned lever groups is equal in length, short end is equal in length, the throw of eccentric of three above crank arms on the first bent axle equates, the throw of eccentric of three above crank arms on the second bent axle equates with the throw of eccentric of more than three crank arm on three-crankshaft, equal in length with the hinged connecting rod of the lever long end of lever group, equal in length with the hinged connecting rod of the lever short end of lever group.
The present invention compared to existing technology outstanding advantage is:
Housing or framework are born and passed to the gravity of the lever of two lever groups that 1, the present invention vertically arranges all by the rotating shaft on its balance pivot, reduced power and energy consumption.
2, on each crank arm on the present invention's the first bent axle, two connecting rods are set and form two groups of connection rod set, and then drive two groups of symmetrically arranged lever groups, connection rod set and two generator generatings to export, because two groups of connecting rods on the crank arm of the first bent axle are all symmetrical arranged, mutual balance or offset because lever swing departed from the partical gravity producing after the vertical line of fulcrum, therefore, the gravity of lever self and the partical gravity producing due to lever swing, can consumption of power and energy, and then make that power consumption of the present invention is minimum, efficiency is high.
3, the throw of eccentric of crank arm of the present invention, connecting rod, lever design are reasonable, can use dry more the living of less power.
4, hinged place of the present invention all adopts bearing supporting, makes the surface friction drag of integral body of the present invention little.
