For further information on the allowable shaft misalignment, please refer to the operating instructions. Permitted Shaft Misalignment Speed in rpm Correction factor FKV 1.20 1.10 1.00 0.70 The axial misalignment may occur dynamically at frequencies up to 10 Hz. For fitting, the maximum gap dimension of S2 max. = S2 + S2 and the minimum Δ gap dimension of S2 min. = S2 - S2 are permitted. The shaft misalignments K , K and K may occur simultaneously (see of the catalogue Δ Δ Δ Δ a r w page 2 “Flender mechanical power transmission couplings available from jbj Techniques Limited”). The permitted shaft misalignment depends on the operating speed. As the speed increases, lower shaft misalignment values are permitted. The correction factors for different speeds are specified in the following table. The maximum speed depending on the respective coupling size and type must be observed!
