Analysis of Influencing Factors of Balanced Vibration Reduction Gear for Three Cylinder Engine Balance Shaft System Based on Balance Index Calculation Model

The balanced vibration reduction gear of balance shaft system for three cylinder engine is the key component to influence the balance performance of system.In order to meet the requirement of processing quality,balance indexes such as mass,moment of inertia and unbalance need to be controlled on the basis of ensuring machining accuracy.Based on introducing structure characteristics of balanced vibration reduction gear,general balance index calculation model for balanced vibration reduction gear with weight-increasing component,weight-losing component,rubber component are established.The key influencing factors of balancing elastic gears are determined by the orthogonal experimental design method and range difference analysis,which provides theoretical basis for follow-up parts design,manufacture and structure optimization.
