Eliminating axial backlash in revolution joint 2
Centrifugal force causes red balls to exert force on yellow grooved washer-plates when shaft rotates, pulling it against bearing face of the blue bearing and the grey nut.
The video shows how the balls move under the influence of centrifugal force to push the plates apart and how the movement of the yellow plates helps to eliminate the shaft’s axial backlash.

Eliminating axial backlash in revolution joint 1
Переглядів 2,9 тис.7 годин тому
Three integral rings on the green shaft slide in grooves of the blue base and yellow cap to prevent axial movement of the shaft. The grooves in the yellow cap are offset axially. The video shows how the spring forces cause the shaft movement to eliminate its axial backlash. The blue base prevents the shaft from moving to the left. The yellow cap prevents the shaft from moving to the right. This...

    Thank you for this Mr. Thang! Theoretically, could this be designed where the input shaft is not internal of the osculating output? For example, could the input shaft be above the output as long as the helical slots on both shafts are linked? Or is there a simpler way of achieving that motion while maintaining constant contact?

    • @thang010146
      @thang010146 День тому

      The output tube is inside the input tube? It's possible, but the structure will be more complicated because an additional shaft must be added in the center as a runway for the pink slider.

    Since 4 spring r used, force is equally distributed. I would recommend to used wavespring. Spring selection is also important factor based on mechanical design & its calculations.

    With backlash mostly being a concern with stop-start cycles of direction changes, I'm not sure how this actually helps since it is dependent on the system being at speed to engage the mechanism. This looks more like a (strange) centrifugal clutch to me. What's a practical example/use of this as an anti-backlash coupling?

      Besides the two orange wheels with a vertical axis, there is also a small blue wheel with a horizontal axis. The latter bears the vertical load. Sorry that this small wheel is hard to spot in the video. Anyway, the wheels in this video are not sturdy enough. There are better designs, but they will make the video complicated and confusing.
