The invention relates to a motorcycle chain tensioning device, two sliding blocks are driven by a sliding block driving mechanism to slide along sliding holes according to the distance between two nuts on the left side and the right side of a rear frame of a motorcycle, so that the axes of two output shafts coincide with the axes of the corresponding nuts on the same side. The output shaft is in transmission connection with the driving shaft through the universal shaft, so that after the sliding block moves, the universal shaft keeps adaptive through angle change. Then a proper sleeve is selected according to the specification of the nut, the sleeve is inserted into the connecting shaft through a square hole and then inserted into the nut through a hexagonal hole, a synchronous driving mechanism drives two gears II to synchronously rotate in the same direction, so that the universal shaft drives the output shaft to drive a driving base to rotate; furthermore, the sleeve is driven to rotate through the connecting shaft, so that the two nuts are driven to synchronously rotate in the same direction, the two ends of the rear wheel of the motorcycle synchronously move backwards, the chain is tensioned, and the situation that the chain and the chain wheel are eccentrically worn due to inconsistent rotating angles of the two nuts is avoided.

    一种摩托车链条张紧装置,根据摩托车后车架左右两侧的两个螺母之间的间距利用滑块驱动机构驱动两个滑块沿滑孔滑动,从而使两个输出轴轴心分别与同侧对应的螺母的轴心相重合,由于输出轴通过万向轴与驱动轴传动连接,因此滑块移动后万向轴通过角度的改变保持适配。之后根据螺母的规格选择合适的套筒,将套筒通过方孔插装于连接轴上,之后将套筒通过六角孔插装于螺母上,通过同步驱动机构驱动两个齿轮Ⅱ同步同向转动,因此通过万向轴驱动输出轴驱动驱动座转动,进一步通过连接轴驱动套筒转动,从而实现驱动两个螺母同步同向转动,使摩托车后轮两端同步向后移动,使链条张紧,避免了两个螺母转动角度不一致导致链条和链轮导致偏磨的情况发生。
