The invention discloses a vibration steel wheel of a vertical vibration road roller. The vibration steel wheel comprises a large steel wheel, a small steel wheel, a first vibration exciter, a reserving mechanism, a second vibration exciter, a third vibration exciter, a fourth vibration exciter and the like. The first vibration exciter is driven by a vibration motor through a coupler to rotate. Thesecond vibration exciter and the fourth vibration exciter rotate in the direction opposite to the rotation direction of the first vibration exciter under the effect of the reversing mechanism. The first vibration exciter and the third vibration exciter are connected through a spline shaft, so that the identical rotation speed and the identical rotation direction of the third vibration exciter andthe first vibration exciter are guaranteed. The resultant force of exciting force generated by the four vibration exciters in the horizontal direction is zero, and the exciting force only exists in the vertical direction and is transmitted to the large steel wheel through a bearing and a bearing cage to conduct compaction operation. Through the reversing mechanism high in load bearing capacity, long in service life and low in transmission noise, the rotation directions of the vibration exciters are changed, a steel wheel vibration exciting device is arranged compactly and simply overall, modularization is easy to achieve, the situation that machining, installation and maintenance are difficult due to the complex structure is effectively relieved, and practicability and popularization value are high.
Description
technical field [0001] The invention belongs to the technical field of vibratory road rollers in road construction machinery, in particular to a vibrating steel wheel of a vertical vibratory road roller. Background technique [0002] The exciting forces of the vibrating steel wheels of the vertical vibratory road roller in the horizontal direction cancel each other out, and only produce directional vibration in the vertical direction, without vibrating disturbance in other directions. When the roller vibrates, the friction between the vibrating wheel and the compacted material in the horizontal direction is very small, and the wear degree of the steel wheel body is small, which prolongs the service life of the vibratory roller and reduces energy loss. Vertical vibratory rollers are suitable for various compacting materials and working conditions, and are widely used in sandy soil, earth-rock filling, asphalt mixture and cement concrete mixture. Good performance, can ensure ...
