Abstract

See full text

A magnetic jack type control element drive mechanism for precision position control of a control element assembly, satisfies the following conditions:

description='In-line Formulae' end='lead'D1=D2=P+D5;description='In-line Formulae' end='tail'

description='In-line Formulae' end='lead'D3=P×2;description='In-line Formulae' end='tail'

description='In-line Formulae' end='lead'D4=D3×(N−½), (N is an arbitrary natural number),description='In-line Formulae' end='tail'

    whereinD1 represents a lift gap of the upper motor assembly;D2 represents a lift gap of the lower motor assembly;D3 represents a space width between tips of adjacent teeth of the drive shaft;D4 represents a gap between an upper latch and a lower latch;P represents pitch that is a distance of ascent or descent of the drive shaft; andD5 represents a margin which is a separation space between the teeth and the upper latch or the lower latch when the upper latch or the lower latch is inserted into the teeth of the drive shaft.
