The specified torsional stiffness “ZN” applies to coupling types ZNN, ZNNA, ZNNV and ZNN for axial displacement. Torsional stiffness of types ZNZS, ZNW, ZNBT, ZNBG, ZNZA and ZNZN on request. The axial misalignment О”Ka must be understood as the maximum permitted enlargement of the hub distance S of the coupling. Angular misalignment О”KW - Types ZNN, ZNZS, ZNW, ZNNV, ZNN for axial displacement: О”KW = 0.5°
- Types ZNBG, ZNNA, ZNZA: О”KW = 0.2°
Radial misalignment О”Kr - Types ZNN, ZNZS, ZNW, ZNNV, ZNN for axial displacement: О”KR ≤ VA · tan 0.5°
- Types ZNBG, ZNNA, ZNZA: О”Kr ≤ VA · tan 0.2°
For the tooth distance VA, see the relevant table for the subassembly.
