| Abstract:According to the actual working conditions of crankshaft gear assembly of certain low-speed diesel engine, the three-dimensional finite element model was set up, and the interference fit was analyzed. The stress distributions of the gear under different interference values were studied, which lead the discipline of the influence of gear assembly interference on the force of gear. Together with the comparison with the results of adding groove model, the methods which improve the stress distribution of the gear were obtained. |
