Taking the right rocker gear box of MG620/1660-WD coal mining machine as the monitoring object,the design of rocker vibration monitoring test bench for rocker coal mining machine was carried out.The functional requirements of the rocker arm test bench are analysed,and the overall scheme design of the test bench is completed,which has the functions of working condition simulation and vibration monitoring.Based on the general scheme of the test bench,the design of the test bench was completed,including the selection of torque transducers,dynamometer selection,structural design of the excitation device,and control system scheme.Typical types of vibration data to be monitored by the rocker arm test bench are determined,and the corresponding monitoring parts of different typical vibration data are pointed out,which reduces the operation difficulty of the test bench and meets the requirement of monitoring the quality of the rocker arm gearbox of coal mining machine.
