振动压路机工作装置的结构对振动压路机的工作性能起着重要的作用。传统的工作装置为单轴圆周激振器,通过改变工作装置的旋转方向改变工作装置的振幅,一般只有两种振幅和两个频率,而且传统的工作装置基本以一种固定的模式持续地作用于被压实材料,不能达到压实度更高的要求。设计开发的能够实现无级调幅机构的新型工作装置有两个关键点,即调幅机构的可控性和智能控制的可行性。新型工作装置的激振单元中有两根平行带偏心体的轴,旋转方向相反,动力从变幅马达传入带动旋转壳体旋转,通过一组5个齿轮可对两根平行的偏心轴的相位角进行调整,以达到调节振幅的目的。新型工作装置可以从最小到最大振幅之间任意调整,实现无级调幅,而且能够实现水平振动,实现不同铺层和不同材料的压实作业。
The structure of vibratory roller working device plays an important role in the working performance of vibratory roller. Conventional working devices are single-axis circumferential exciters that change the amplitude of the working device by changing the direction of rotation of the working device, generally only two amplitudes and two frequencies, and the conventional working device functions essentially continuously in a fixed mode In the compacted material, can not achieve higher compaction requirements. There are two key points in designing and developing a new type of working device that can realize a stepless amplitude modulation mechanism, that is, the controllability of the amplitude modulation mechanism and the feasibility of intelligent control. In the new type of working unit, there are two parallel eccentric shafts in the exciting unit, the opposite directions of rotation, the power is transmitted from the variable-amplitude motor to drive the rotating housing to rotate, and the two parallel eccentric shafts Phase angle adjustment, in order to achieve the purpose of adjusting the amplitude. New workstations can be adjusted from minimum to maximum amplitude to achieve stepless amplitude modulation, but also to achieve horizontal vibration, to achieve different ply and different materials compaction operation.
