Avoiding and calculating angular errors
L1
L2 (≥ L1)
INFO
For further information, please call the telephone hotline at +49 (0)30 69003-111.
Instruction:
a) Make sure that concentricity errors of the drive shaft do not exceed 0.2 mm (0.03 mm rec-
ommended) to prevent angular errors.
b) Limit such angular errors by increased gap L1. For doing so, various torque plates for are
available on request.
c) Note that length L2 of the torque arm should be ≥ L1. Where not possible, consider L2.
d) To calculate angular errors Δp
mech
proceed as follows ( R = runout error in mm and L1 = ver-
tical gap of torque arm towards the device center in mm):
Δp
mech
= ±90°/π × R/L1
Calculation example:
With R= 0.06 mm and L1 = 69.5 mm, the angular error Δp
mech
is ±0.025°.
