In a spindle system with a balance shaft, the main shaft and the balance shaft

The structural connection is established through gear transmission. Therefore, when modeling the main shaft system of the balance shaft, the influence of the balance shaft on the main shaft is converted into the dynamic reaction force generated by the gear on the main shaft during the gear transmission process. The gear is simplified into an equivalent wheel, and the simplification of other mechanisms is the same as that of the general carpet tufting machine spindle system. At the same time, in order to facilitate the calculation of subsequent unbalanced response analysis, the number of nodes of the master axis and the slave axis is the same, and the total number of nodes is set to 23. The lumped parameter model of a spindle system with a balance shaft is shown in Figure 5.
