The invention relates to the vibration reduction technology of Mecanum wheels, in particular to a Mecanum wheel vibration influence eliminating device which comprises a retainer and a potential difference compensation mechanism, and the potential difference compensation mechanism is provided with a wavy contact surface; the lower part of the longitudinal moving mechanism is in contact with the wavy contact surface; under the control of the driving mechanism, the lower end of the longitudinal moving mechanism longitudinally reciprocates along with the movement of the wavy contact surface; when the longitudinal moving mechanism makes contact with the highest point of the protruding face, a wheel shaft of the Mecanum wheel is located at the lowest point, when the longitudinal moving mechanism makes contact with the lowest point of the concave face, the wheel shaft of the Mecanum wheel is located at the highest point, and the longitudinal displacement difference of the longitudinal moving mechanism is equal to the longitudinal displacement difference of the wheel shaft. In the invention, the difference compensation mechanism and the Mecanum wheel are arranged to move at the same frequency, and for the longitudinal moving mechanism, the difference compensation mechanism and the wheel shaft always keep opposite equidistant movement, that is, the distance between the longitudinal moving mechanism and the ground is constant, so that the problem that the vibration of the Mecanum wheel affects the stability of equipment is solved.
本发明涉及麦克纳姆轮的减振技术,具体为麦克纳姆轮振动影响消除装置,包括保持架以及位差补偿机构,位差补偿机构具有波状接触面;纵向移动机构的下部接触所述波状接触面;在驱动机构的控制下纵向移动机构的下端随波状接触面的运动而纵向往复移动;且当纵向移动机构接触凸起面的最高点时,麦克纳姆轮的轮轴位于最低点,纵向移动机构接触凹陷面的最低点时,麦克纳姆轮的轮轴位于最高点,且纵向移动机构的纵向位移差等于轮轴的纵向位移差。本发明中,设置差补偿机构与麦克纳姆轮同频运动,且对于纵向移动机构而言,其与轮轴总是保持反向的等距移动,即纵向移动机构与地面的距离是恒定的,从而解决麦克纳姆轮的振动影响设备稳定性的问题。
