For ND, the smallest hub diameter of ND1 or ND2 is to be used. ND1 or ND2 in mm see
Speeds, geometry data and weights (Page61)
The alignment value for ΔS can be found in Section Distances between teeth VA and recom-
mended alignment values for angular and radial misalignment (Page67).
5.3.2.3 Radial misalignment5.3 Aligning the coupling
For the ZNN, ZNNV, ZNZS and ZNZV types, the maximum possible radial misalignment
ΔKr
max
corresponds to a maximum angular deviation for each coupling half of ΔKw
max
=0.5°.
For the ZNNA and ZNZA types, the maximum possible radial misalignment ΔKr
max
corres-
ponds to a maximum angular deviation for each coupling half of ΔKw
max
=0.2°.
Determine the value ΔKr.
ZNN, ZNNV, ZNZS, ZNZV types:
ΔKr ≤ VA · tan 0.5° ≈ VA / 100
ZNNA, ZNZA types:
ΔKr ≤ VA · tan 0.2° ≈ VA / 300
The values for VA and the alignment value for ΔKr can be found in Section Distances
between teeth VA and recommended alignment values for angular and radial misalignment
(Page67).
5.3.2.4 Angular and radial misalignment5.3 Aligning the coupling
Angular and radial misalignment can occur at the same time. Comply with the following con-
dition:
ZNN, ZNNV, ZNZS and ZNZV types:
arctan (ΔKr / VA) + ΔKw ≤ 0,5 °
ZNNA and ZNZA types:
arctan (ΔKr / VA) + ΔKw ≤ 0.2 °
You can find the values for VA in Distances between teeth VA and recommended alignment
values for angular and radial misalignment (Page67).
