ServoFlex - Type 338 Match code Mönninghoff shaft couplings are indicated by the following match code: 338 . A . B . C A coupling size B design C options of mounting and integrating other individual characteristics: • bore size with keyways According to these characteristics, we design individual solutions concerning transmitted torque, engaging behavior or rotation speed. Our engineers can assist with finding an application-specific coupling at any time. Together, we can develop individual and innovative solutions for extreme operating conditions. Ordering example Mönninghoff ServoFlex -...

ServoFlex - Type 338 Coupling size When dimensioning a Mönninghoff ServoFlex coupling, several technical preconditions should be considered: • Membrane coupling transmit torque without virtually any dampening. Therefore the size must be determined so that a possible peak torque - caused by drive or load - does not exceed the specified nominal torque TKN. We recommend that the torque which have been determined theoretically are corrected with the appropriate safety or operating factor. TKN > T  KB oder TKN > T  KS • As misalignment reduces the transmitted torque of the coupling, the values...

ServoFlex - Type 338 Coupling size - starting factor If the starting factor is bigger than 2 times of the coupling torque, or if there are more than 50 starts/stops per hour, please consult our engineers. Coupling size - angular misalignment factor When calculating the angular misalignment factor, the radial and axial misalignment must also be taken into account. angle misalignment radial misalignment axial misalignment ∆Ktotal = ∆Ka + ∆Kr + ∆Kw ≤ 100% modification of ∆Ka [mm] and ∆Kr [mm] in ∆Kwa [°] an ∆Kwr [°] ∆Kwa = arcsin ∆Kwr = arcsin ∆Kwg = ∆Kw + ∆Kwa + ∆Kwr [°] Kwg = total angular...
