ArcOflex - Type 314 Match code Mönninghoff shaft couplings are indicated by the following match code: 314 . 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 ArcOflex -...

ArcOflex - Type 314 Coupling size When dimensioning a Mönninghoff ArcOflex 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...

ArcOflex - Type 314 Coupling size - starting factor If the starting factor is bigger than 2 times of the coupling torque, or there are more than 50 starts/stops per hour, consult our technical department. Coupling size - angular misalignment factor When calculating the angular misalignment factor, the radial and axial misalignment must also be taken into account. angular misalignment radial misalignment axial misalignment ∆Ktotal = ∆Ka + ∆Kr + ∆Kw ≤ 100% modification of ∆Ka [mm] and ∆Kr [mm] in ∆Kwa [°] an ∆Kwr [°] ∆Kwg = ∆Kw + ∆Kwa + ∆Kwr [°] x Kwg = total angular misalignment Kwa =...

ArcOflex - Type 314 Design The Mönninghoff ArcOflex coupling is offered in different designs • equalization of axial and angular misalignment with single joint design • additional equalization of radial misalignement with double joint design Design 1: single joint Design 3: double joint with variable spacer Design 2: double joint with standard spacer Design 4: double joint with small spacer Vertical assembling • when vertical assembling is required, an additional support has to be used between the lower hub and spacer • please order: for vertical asse

ArcOflex - Type 314 Design & style There are different styles of installing the ArcOflex coupling. According to the mounting style, the total coupling length varies. Type 2, style X: Alignment of both hubs to the outside Type 2, style Y: Alignment of one hub to the inside Type 2, style Z: Alignment of both hubs to the inside Styles & disc pack Disc pack • stainless steel • connected via fitting screws • optimized with finite element design methods Radial assembling of the disc pack is only possible in design

ArcOflex - Type 314 Spacer coupling design 3 The double joint design with variable length has some additional properties of the spacer to consider. • stainless steel or CFK/GFK possible • length changes through temperature variations • limitation of spacer length to 2900 mm is due to the manufacturing process • further limitation of the spacer length is due to critical speed • when vertical assembling is required, an additional support has to be used Technical data Size see diagramm „critical speed for design 3“ 17,13 torsional stiffness, pipe bore d, d1 H7, keyway acc. to DIN 6885/1...

ArcOflex - Type 314 Operating speed design 3 The critical speed of the shaft coupling changes according to the length of the spacer. Our product is the know-how, with hardware as an added bonus.
