6. simple in structure, good manufacturability, cost of production are low
Design of part in the internal-combustion engine of the present invention is simple, good manufacturability, cost of production are low, has completely abolished the crankshaft-and-connecting-rod of complex structure, manufacturing difficulty.
7. bearing capacity is larger, and rotating speed is steady
The transmission of heterogeneous shock wave roller oscillating tooth is multiple tooth engagement, stable drive, and oscillating tooth can jointly be shared load and realize power dividing.So internal combustion engine operation is steady, the ability of opposing shock and vibration is stronger, and bearing capacity is large.
