PRE-LOAD SETTING PROCEDURES 10
DOUBLE STIFFNESS PRE-LOAD
• Mount the stack you want to use and turn the platform until in contact with the Belleville
stack
• Turn the platforms until distance A is the same on both sides
• Check distance B to be less than 6.5mm, if more, replace adjustment spacer
• Mark this platform position as the “zero pre-load” notch
• Turn both left and right platforms the amount of notches to set the desired pre-load.
One turn of platform is 15 notches corresponding to 1.5mm displacement
(1 notch = 0.1mm)
INFINITE STIFFNESS PRE-LOAD
• Set the pre-load as described for the double stiffness procedure here above
• Mount nut D in contact with the platform
Tighten counter nut E against nut D (check nut D stays against the platform)
