我公司生产的YZ系列振动压路机，振动轮工作时由于振动轴转速高、激振力大，使与之接触的油封易磨损、变形，失去密封作用，致使振动室内润滑油流失，为此必须及时更换油封。油封的安装位置见图1。欲更换油封，必须先拆下振动马达的联轴器。该联轴器与振动轴由平键连接，其配合 YZ series vibratory roller produced by our company, vibrating wheel work due to the vibration shaft speed, excitation force, the contact with the oil seal easy to wear, deformation, loss of sealing effect, resulting in the loss of vibration chamber oil, which must be timely Change the oil seal. Oil seal installation location shown in Figure 1. To replace the oil seal, you must first remove the vibration motor coupling. The coupling and the vibration shaft by the flat key connection, its cooperation
