© Siemens AG 2015 FLENDER Standard Couplings Flexible Couplings — N-BIPEX Series General Permitted shaft misalignment The permitted shaft misalignment depends on the operating speed. As the speed increases, lower shaft misalignment values are permitted. The following table shows the correction factors for different speeds. The maximum speed depending on the re- spective coupling size and type must be observed! The axial misalignment may occur dynamically at frequencies up to 10 Hz. For fitting, the maximum gap dimension of S2 max. = S2 + Δ S2 and the minimum gap dimension of S2 min. = S2 - Δ S2 are permitted.
The shaft misalignments Δ K a , Δ K r and Δ K w may occur simulta- neously ( see page 2/2 ). Δ K perm = Δ K 1500 ⋅ FKV Correction factor FKV 1.20 1.10 1.00 0.70 Assignment of N-BIPEX sizes to output P M of IEC standard motors The assignment applies for an service factor of 1.25 and the use of a standard cam ring (92 ShoreA). 9 9/5 Siemens MD 10.1 · 2015 Speed in rpm 500 1000 1500 3000 Three- phase motor Motor N-BIPEX coupling Motor N-BIPEX coupling Motor N-BIPEX coupling Motor N-BIPEX coupling DE shaft end D x E acc.
