After thumbing through the NOOK catalog I read the first few pages regarding lash in ACME lead screws. They recomend using anti lash flanges with periodic adjustments for wear.
Basically the say to mount your anti lash flanges on either side of the block and create compression similar to the way preloaded ball nuts work.
This got me thinking about providing a constant light flow of lube from the main flood pump to allow the anti lash flanges to be constantly lubricated during use to not only reduce wear, but to keep the flange clean and running smooth.
A small access hole drilled near the block on all axis's could allow the introduction of a fluid flow that would stay pointed at the block yet move with the ways.
This would reduce the lash, keep the threads clean and reduce wear. |
