Vector Analysis Of Crankshaft Web Deflections: Deflections can be converted Into calculated stress values on a throw-by-throw basis

摘要

Crankshaft web deflection measurements have historically been used to evaluate crankshaft alignment and as criteria to take action to prevent crankshaft failure [1]. Research has correlated web deflection measurements to peak stress levels in the crankshaft fillets. Web deflections can now be converted into calculated stress values on a throw-by-throw basis. These calculations account for variations in pin and stroke dimensions and provide more reliable criteria to evaluate the risk of failure.
