andard Balancing of shaft and coupling hub after keyseating, but without parallel key. Not used in practice. Marking of shaft and hub with "" (for "no"). The length of the parallel key is determined by the shaft keyway. Coupling hubs may be designed considerably shorter than the shaft. To prevent imbalance forces caused by projecting parallel key factors when balancing in accordance with the half parallel key standard in the case of applications with high balancing quality requirements, grooved spacer rings can be fitted or stepped parallel keys used. Flender Balancing Standard The balancing quality level, together with the operating speed, results in the maximum permissible eccentri-city of the center of gravity of the coupling or the coupling subassembly. In the Flender article number the balancing quality can be preset with the help of the order code. Addi-tionally, also the balance quality level to DIN ISO 2 can be preset together with the operating speed belonging to it, which then be taken as priority. perm = 9 ecoupl epermG Permitted eccentricity of center of gravity eperm in Ec centricity of center of gravity of coupling ecoupl in Balancing quality evel in mm/ oupling speed in rpmEccentricity of center of gravity of coupling ecouplFlender balancing qualityOrder code maximum 1 standard balancing without specification maximum 4 fine balancing W0 maximum 1 micro-balancing W0 better than 1 special balancing on request /1 FLENDER STANDARD COUPLINGS | INTRODUCTION 4 4 5 5 6 6 7 7 8 8 9 9 1 1 1 1 1 1 1 1 TECHNICAL INFORMATION 1G 4G 1G 1G 2G 4 1 2 8 4 8 1G 1.6G 2.5G 6.3 G_MD1_EN_0aEccentricity of center of gravity eperm. in Coupling speed in rpm On requestMicro-balancingFine balancingStandard balancing Example: Coupling speed = 1 rpmrequired balancing quality level 6.3 perm = 9 = 9 mG 6.3 1 Thus, the required eccentricity of center of gravity is 4.5m.
