4.9.4 Installing the deflection unit ’X’
Æ Fit the elastomeric spring (item 10 in Fig. 4.9 - 1) on the new deflection unit (item 8 in Fig.
4.9 - 1
).
Æ Use the two M6 x 10 hexagon socket-head screws (item 7 in Fig. 4.9 - 1) to fix the deflection
unit (item 8 in Fig. 4.9 - 1
) to the gantry.
Æ Align the ’external’ brake (item 5 in Fig. 4.9 - 1) so that it is parallel with the braking surface and
fix to the deflection unit (item 8 in Fig. 4.9 - 1
) using the two M3 x 8 hexagon socket-head
screws.
Æ Place the toothed belt (item 9 in Fig. 4.9 - 1) around the synchronizing disk of the deflection
unit (item 8 in Fig. 4.9 - 1
).
PLEASE NOTE 4
See Fig. 4.9 - 2, page 113 onward, for the following assembly steps. 4
Æ Feed the toothed belt into the opening (item 3 in Fig. 4.9 - 2) in the tension jack (item 2 in Fig.
4.9 - 2
) so that it runs approximately 270° around the ’long’ synchronizing disk (item 4 in Fig.
4.9 - 2
).
Æ Place the tensioning key (item 5 in Fig. 4.9 - 2) on the synchronizing disk (item 4 in Fig.
4.9 - 2
).
Æ Use a size 8 Allen key to turn the synchronizing disk (item 4 in Fig. 4.9 - 2) clockwise.
Æ Screw the hexagon socket-head screw (item 7 in Fig. 4.9 - 2) into the threaded hole in the
spacer bolt (item 6 in Fig. 4.9 - 2
) and pre-tension the X-axis toothed belt.
4.9.5 Settings
Æ
Push the head mount (item 1 in Fig. 4.9 - 2) towards X-axis motor unit as far as the stop on the
elastomeric spring.
Æ Turn the hexagon socket-head screw (item 7 in Fig. 4.9 - 2) to set the belt tension to
53 Hz + 1/-3 Hz.
CAUTION 4
Do not overstretch the toothed belt when adjusting the belt tension. 4
Æ Secure the hexagon socket-head screw (item 7 in Fig. 4.9 - 2) with the locknut (item 8 in Fig.
4.9 - 2
).
