7.5.1 Axes Couplings
This procedure is for mounting the coupling components to the motor out-
put shaft and ball screw.
• Following this procedure, it will be necessary to check and reset the
axis reference point, using the
CNC
Grid Shift parameters.
To assemble coupling (
Figure 7-10
) proceed as follows:
1. Clean and inspect all components (clamp rings, coupling, clamp ring
retainer, motor shaft, and ball screw end. Use a stone to remove any
nicks or dings, replace components if necessary or if gaulding is seen
on clamp rings.
2. Place sleeve [7] into the coupling [6].
3. Install the motor side clamp rings [4] and [5] onto sleeve [7]. Orient and
install the “male” ring [5] first and then install the “female” ring [4], as
shown.
4. Install the clamp ring retainer [3] using six (M6x25) screws [2] . Tighten
the screws just enough to hold the clamp rings captive, but not
compressed.
5. Install the ball screw side clamp rings [11] and [12] onto sleeve [7].
Orient and install the “male” ring [12] first and then the “female” ring
[11], as shown.
SPANN Rings
SPANN ring couplings eliminate hard-keyed shafts and allow slippage at the coupling
to minimize machine and drive component damage in the event of a “crash”. This slip-
page may change the ball screw-to-motor pulse coder relationship, changing the loca-
tion of the axis reference point, which can be corrected using the CNC Grid Shift
parameter.
