Problems solved by technology

Therefore, the bearing pads 3 and 4 are always subjected to downward force, which is easy to aggravate the uneven wear of the bearing pads 3 and 4
And, this downward force finally acts on the crankshaft 2, thereby causing the biased wear of the crankshaft 2 at the supporting point on the cylinder block 1

Abstract

The invention relates to an integrated crank internal-combustion engine, which comprises: three input cranks, one output crank, and a cylinder. Wherein, said input crank and output crank are rotationally mounted inside the cylinder; the input cranks are uniformly distributed on one circumference; the output crank is at the center of said input crank and parallel with said input crank; at least one group of external brass is arranged along the input crank; at least one group of internal brash is arranged along said input crank and output crank. Via aforementioned arrangement, the force points of brass are dispersed, to improve the force condition of crank and brass, and since the force directions are not toward to one direction, the force of output crank can be balanced via the applied force between input and output cranks, to improve the force condition of cylinder.

Description

technical field [0001] The invention relates to an internal combustion engine. Background technique [0002] The crankshaft used in the internal combustion engine of the prior art is shown in Figure 1, the phase difference between the bearing bushes 3 and 4 is 180 degrees, and when the piston rod 5 rotates the crankshaft 2, the crankshaft 2 outputs power. When the piston rod 5 is working, the direction of the applied force on the connected bearing bush 3 is always downward, and no matter whether the piston rod 6 is working or not, the direction of the applied force on the bearing bush 4 connected with the piston rod 6 is also always downward. Therefore, the bearing bushes 3 and 4 are always subjected to downward force, which is easy to aggravate the uneven wear of the bearing bushes 3 and 4 . And, the downward force finally acts on the crankshaft 2 , thus causing biased wear of the support point of the crankshaft 2 on the cylinder block 1 . Contents of the invention [0...
