TECHNICAL CHARACTERISTICS AND GENERAL INFORMATION 1. OUTPUT TORQUE 1.1 Reference torque M2’ (N.m) Indicative output torque to easily establish the performance class for each gearbox basic size. 1.2 Gear motor delivered torque M2 (N.m) This is the net torque delivered to the output shaft, with installed power Pn, safety factor S, which will yield a theoretical lifetime of 10000 hours. This torque value takes gearbox efficiency into consideration. 1.3 Nominal torque Mn2 (N.m) Torque transmission at output at uniform continuous load, service factor fs=1 for different fixed values of the life...

Intermittent duty Continuous duty (tf : operating time under load) Cyclic duration factor % (l) 4. DYNAMIC EFFICIENCY ηd Obtained from the ratio of output power P2 to input power P1 according to the following equation: ηd=P2/P1 (F6) Its value is a function of the transmitted power, the speed, the reduction ratio and oil temperature and viscosity. The maximum efficiency values are shown in the table (2) below. Table 2: No stage L1 5. REDUCTION RATIO i This is the ratio of gearbox input speed to gearbox output speed. i=n1/n2 (F7) 6. ANGULAR SPEED 6.1 Input speed n1 (min-1) Refers to the speed...

12. VERIFICATION After selecting the drives units, please check the following: a) Thermal power Make sure that thermal power of the gearbox (shown in the tables in the chapters dealing with the gear unit series captioned) is equal to or greater than the power required by the application according to equation (F5) on page 5. If this condition is not respected, select larger gearbox or apply a forced cooling system. Example of oil re-circulation cooling system: Maximum torque Make sure that the maximum torque (considered as instantaneous load peak torque or starting torque under load) does...

Define the trust load position X onto shaft. Check this value with the chart indicating the load Rx1 and Rx2 bearable by the gearbox. Check that the following is satisfied: (F20) Rc1 <= Rx1×fh1 (F21 ) Rc2 <= Rx2×fh2 Where fh1 and fh2 the radial and thrust load corrective factor depending on the required life factor Fh1 and Fh2. Thrust loads check the thrust load, when exerted onto the output shaft, as specified for the radial load. The following should be satisfied: (F22) ±Ac2 <= ±An2×fh2 when a thrust load is combined with an axial load contact Ningbo planetary gearbox sales department....
