Wear can occur in rolling way of multi-loop layout ball screw assembly due to uneven distribution load of each loop
the wear is serious for heavy load ball screw especially.By introduction of reverser anti-phase layout in screw nut and analysis of the reason
it is advanced that reverser anti-phase layout can make load of each loop balls beared well-distributed
and improve screw and nut state of force
contribute to force equilibrium especially when there are setting error.Also influence of nut dimension is analyzed by adopting reverser anti-phase layout mode.
