The stress autobalance of portion's oscillating tooth, it is existing there is no eccentrically mounted cam is needed in a tooth difference Oscillating Tooth Gear Reducer in transmission device
Inertia force, exciting force and tilting moment etc., avoid the vibrational excitation of transmission device from transmission principle, to be conducive to improve
The efficiency of transmission, mechanical friction abrasion is also smaller, and oil consumption is low, and internal-combustion engine life-span is longer.
5. optimization property is strong
The guide groove trajectory curve equation of two-phase balance shock wave device and the slot type cam on left cover end tooth wheel is cosine function,
And curvilinear equation form is simply consistent, is conducive to optimization design.Since the characteristics of motion of piston depends entirely on cam removable tooth frame
Guide groove geometric locus, so four phase cam wheels on cam removable tooth frame can be designed by choosing appropriate piston motion rule
Exterior feature, and appropriate piston motion rule can make burning abundant, perfect, the fuel thermal energy utilization rate of the gas in cylinder high.
6. structure is simple, good manufacturability, production cost are low
Design of part in inventive combustion engine is simple, good manufacturability, production cost are low, completely abolished structure is complicated,
Difficult crankshaft-and-connecting-rod is fabricated, mostly uses the standardized element that steel ball etc. is versatile, is manufactured by specialized vendor, and universal
The radius of steel ball moving teeth in ball component is identical as the radius of universal steel ball in oscillating tooth carrier, therefore two-phase balance shock wave device and left cover
The guide groove section arc radius of slot type cam structure is all the same at right end three outside end tooth wheel and cam removable tooth frame, facilitate manufacture and
Reduce cost.
