ABSTRACT:
A nut assembly intended for use with a lead screw in precision movement devices for compensating for harmonic error from the lead screw by utilizing one or more partial nuts which are opposed along an axis of the lead screw such that the partial nuts ride the lead screw independently. An averaging apparatus is used to hold the partial nuts such that as the partial nuts follow the harmonic error, the error is averaged through the averaging apparatus to compensate for the harmonic error allowing the resulting motion of the nuts to be substantially linear.
