With the development of technology, the balance requirements for parts are getting higher and higher. Taking the pulley as an example, the unbalance amount is increased from 300g·mm to 400g·mm. The method of static balance calibration can no longer meet the requirements of parts balance. The following is an application example of the SH400-100 vertical dynamic balancing machine. 1. Balance part parameters and preparation work Figure 1 is the power output pulley, speed n=2000r/min, uneven
