3.5 Guideways on main axes
All the main linear axes have guiderails and S
(standard) precision circulating ball steering,
with a max. 0.01 mm (0.0004 inch) play and no
pretensioning.
Each of the guide units running along the ground
guiderails with hardened tracks has 4 rows of
balls.
The guiderails and guide units can be replaced
separately. The reversing flaps on the guide
units have an integrated sealing lip and a force-
feed lubrication nipple or a connector for the
central lubrication circuit.
3.6 Motors / Gearing
3.6.1 Maintenance-free servo three-phase
a.c motors for main linear axes
The servo controlled axle drives are fitted with
integrated motor brakes which are activated at
the end position.
Standard high quality bearings permit speeds
ranging from approx. 1 revolution per day up to a
maximum of 4000 rpm (depending upon the
gearing).
The servo drives produce a constant sustained
torque over the entire speed range up to a
maximum ambient temperature of 45°C (113°F).
This produces a motor temperature of 60°C
(140°F) depending upon the thermal motor time
constant.
3.6.2 Planetary gearing for the X (Z) and Y
and Z axis drive.
• single stage
• Circumferential backlash < 8 angular
minutes
• Max. input speed of 4500 rpm.
• 94-97% efficiency at a max. operating
temperature of 100°C (212°F)
• Shaft linked to motor by a clamping hub
(sleeve shaft)
• Smooth drive shaft with clamping hub
link
• Maintenance-free synthetic oil (refer to
Section 7).
