某小型通用发动机动平衡分析及其对策

Analysis and Strategies of Count-balance for A Certain General Utility Small Engine

通过对某小型通用风冷发动机的曲轴动平衡分析,找出了曲轴设计上的不足之处,采取了改变平衡重布置方式的措施,通过实验手段证明其有效地减少了发动机的振动。

Through the analysis of count-weight for balance on crankshaft of a small air-cooled engine,some disadvantages have been figured out for the crankshaft design.Measures were taken to improve the engine balance by changing count-weight on crankshaft.The test results show that it effectively reduced the engine libration.
