万向传动轴工作时转速很高,传递的扭矩也很大,因此做好轴的平衡就很重要。然而大多数的汽车修理企业由于缺少必要的设备,修理时,万向传动轴都不进行动平衡。苏联一汽车修理厂制成了简易的万向传动轴动平衡试验台,并在运用(见图)。刚性机座15上装电动机1和前轴承座3。在前轴承座中装置轴,此轴在轴承中通过联轴 Universal drive shaft work speed is high, the transmission of torque is also great, so the balance of the shaft is very important. However, most auto repair companies do not balance the PTO shaft due to lack of necessary equipment and repair. A Soviet Union automobile repair shop made a simple universal shaft dynamic balance test bed, and the use of (see photo). The rigid base 15 is equipped with a motor 1 and a front bearing 3. In the front bearing housing shaft, the shaft through the shaft coupling
