FLENDER Standard Couplings Torsionally Rigid Gear Couplings — ZAPEX ZW Series © Siemens AG 2015 General information ■ Technical data Power ratings 4 In the case of type ZWTR, the rated torques which deviate from the above are specified in the dimension table. The stated torsional stiffness „ZW“ applies to coupling types ZWN and ZWNV. Torsional stiffness of the remaining types on request. The axial misalignment Δ K a must be understood as the maxi- mum permitted enlargement of the hub distance S of the cou- pling. The axial misalignment for the types ZWBT, ZWBG and ZWNV is Ѕ Ч Δ K a . Angular misalignment Δ K w • Types ZWN, ZZS, ZZW, ZWH, ZWB, ZBR, ZWS: Δ K w = 1° • Types ZWBT and ZWBG:
Δ K w = 0.2° • Type ZWSE: Δ K w = 0.4° Radial misalignment Δ K r • Types ZWN, ZZS, ZZW, ZWH, ZWB, ZBR, ZWS: Δ K r ≤ VA ⋅ tan 1° • Types ZWBT and ZWBG: Δ K r ≤ VA ⋅ tan 0.2° • Type ZWSE: Δ K r ≤ VA ⋅ tan 0.4° For the tooth distance VA, see the relevant table for the subas- sembly.
