Abstract :
The pusherchain transmission is the core of shearing device, which occurred to the failure of getting stuck resulted in the chain-axis deformation. First, the paper presents the analysis of FMEA, FTA for deformation failure, and carries out the simulation research for failure analysis on wear-failure for chain plate. Then, based on the random effects of significant geometry, material properties, transmission force, the quantitative analysis is used for the sensitive variables which influence the reliability of pusherchain and finds the weakness. At last, the paper analyses the reliability optimization and improves the reliability from 0.7264 to 0.9836, which improves the reliability of mechanism motion reliability and reduces the motion risk in the future.
