Hydraulic vibrating rod machine-mounted hard rod structure

TANG JUNPING / CAO YI

The invention discloses a hydraulic vibrating rod machine-mounted hard rod structure which is characterized in that driving force is provided for a hydraulic motor through external oil liquid, and a head output shaft of the hydraulic motor is connected with an eccentric shaft through a coupling piece; the hydraulic motor drives the eccentric shaft to rotate at a high speed, and due to the fact that the eccentric shaft has a certain weight, has a certain eccentric distance and generates a certain torque during rotation, the eccentric shaft has huge centrifugal force under driving of the hydraulic motor. The two ends of the eccentric shaft are in interference fit with the upper bearing and the lower bearing respectively, the upper bearing and the lower bearing are installed on the upper bearing seat and the lower bearing seat respectively, the upper bearing seat and the lower bearing seat are in interference fit with the outer sleeve, and finally centrifugal force of the eccentric shaft is transmitted to the rod body. And the vibrating rod body vibrates at high frequency.

本发明公开了一种液压振捣棒机载硬棒结构，通过外部的油液为所述液压马达提供驱动力，所述液压马达头部输出轴通过所述联轴件与所述偏心轴连接；所述液压马达驱动所述偏心轴使其高速旋转，由于所述偏心轴自身具有一定的重量，又因具有一定的偏心距和转动产生一定的转矩，导致所述偏心轴在所述液压马达的驱动下的具有巨大的离心力；所述偏心轴两端分别与所述上轴承和所述下轴承过盈配合，所述上轴承和所述下轴承分别装在所述上轴承座和所述下轴承座上，所述上轴承座和所述下轴承座与所述外套筒过盈配合，最终，所述偏心轴的离心力传动到棒体上，使振捣棒体高频震动。
