Using a gear to make its synchronous reverse rotation eccentric shaft horizontal force is offset

In recent years, the following two new trends have emerged in the research and development of vibratory pressure circuits at home and abroad: First, in terms of compaction method, the vibration of the vibratory roller currently used is circular vibration, but in recent years, an oscillating roller has appeared. It is called a horizontal vibratory roller, which is a central shaft connected to the vibration drive motor shaft. It drives two parallel belts and an eccentric shaft through a toothed belt. The compaction roller is produced to be nearly parallel to the compaction surface by adjusting the relative position of the eccentricity. The two-way extrusion shear force, so its compaction is formed by the combined action of shear force and static pressure.

The vibratory roller currently used mainly relies on the dynamic pressure of the impact to complete the compaction. Therefore, the oscillating roller has the advantages that the compaction speed in the shallow layer is faster than that of the vibratory roller, the ground vibration is small, the compacted ground is flat, and the energy consumption is small. Germany's GAMM company's vibratory roller has formed a series of products on the market. China has also carried out extensive theoretical and experimental research work, and the YZD10 vibratory roller has been developed by Xuzhou Engineering Machinery Factory and Xi'an Highway College.

Vertical vibratory roller, which has two parallel eccentric shafts in the front and rear rollers of the roller, installed in the opposite horizontal direction, and rotated synchronously with the gears, so the horizontal force of the eccentric shaft is offset, and only the vertical direction is generated. The force that helps to compact the thicker layers of soil. At present, China is also carrying out this development and trial work.
