我公司一台BW219D-2型压路机在使用过程中,前钢轮强振突然消失,只有微振。 该种类型的压路机是由液压泵驱动振动马达,再由激振马达驱动激振轴上的偏心块,从而引起钢轮振动的。马达的转动速度控制着压路机的强振和微振,即控制振幅的大小。钢轮的两根激振轴是通过中间的联轴器连接在一起的,并带动偏心块一起旋转引起振动。 My company BW219D-2-type roller in use, the former steel suddenly disappeared strong vibration, only micro-vibration. This type of roller is driven by a hydraulic pump motor, and then excited by the excitation motor drive shaft eccentric block, causing the drum vibration. The rotational speed of the motor controls the strong vibration and micro vibration of the roller, that is, the amplitude of the control. The two steel excitation shaft is connected through the middle of the coupling, and bring the eccentric block together to cause vibration.
