Technical data for the mounting of couplings:
The Drive Set
Drive Set KRF 8 ZR, 0.0.627.46
Use of high-strength aluminium alloy Coupling Housing with prepared centring
piece on the drive Reverse Unit
Coupling Housing with plenty of area available on the motor side for the
customer to machine as required.
New coupling made from stainless steel
A complete component and therefore entirely play-free
Nominal torque: 60 Nm (
Caution
! Timing Belt transfers only 23 Nm)
Axial deviation:
0.2 mm
Radial deviation: 0.3 mm
Angular deviation: 1.4°
Clamping screws: DIN 912 - M6
Tightening torque: 14.5 Nm
Up to 50 % deviation, full nominal torque can be transmitted.
At 100% deviation, 50% of the nominal torque can be transmitted.
Deviations in between are linear in nature.
Axial deviations do not affect torque
This coupling cannot be used with the other Reverse Units because the
attachment dimensions of the Reverse Units are far more generously toleranced
(die-cast parts). Axial and radial deviations are too great.
