Influence Mechanism Research of Structural Parameters to Magnitude of Interference Between Diesel Engine Crankshaft and Timing Gear

Based on the numerical simulation of Interference contact state to crankshaft gear under different structural parameters, the distribution of the crankshaft gear assembly pre-stress was analyzed.Focus on the analysis of influence mechanism of the structural parameters to the amount of interference.The results show that the influence of gear inside diameter and crankshaft inner diameter is more significant than others. The results for the follow-up diesel engine crankshaft and timing gear designed to provide the basis also can Interference contact design provides a reference for the machinery industry.
