动平衡可用许多仪器进行测量与平衡,但都需要将回转体拆下来,放在动平衡仪上去单独进行平衡,这样将有两个缺点:①对于大型机器的回转体,很难找到合适的动平衡仪进行测量;②拆下平衡与在机器上工作的实际情况有差别,如回转速度、负荷、传动链等。因此,不拆卸机器,而直接在实际运转的条件 Balancing can be measured and balanced by many instruments. However, it is necessary to disassemble the bogie and place it on a balancer to balance the bogies separately. This has two disadvantages: (1) For a large machine, it is difficult to find a suitable moving body Balancer to measure; ② Remove the balance and the actual work on the machine are different, such as speed, load, drive chains and so on. Therefore, do not disassemble the machine, but directly in the actual operating conditions
