 Sizing 1. Conditions (1) Motion profile Output shaft speed nT : Maximum output shaft speed (r/min) t1 : Acceleration time (s) t2 : Constant speed time (s) Output torque Ta Tc Ta : Acceleration torque (N•m) Tc : Constant speed torque (N•m) (2) Load moment of inertia Ir Use the tables on page 13 to calculate Ir, the load moment of inertia on the output shaft of the reducer. Ir: Load moment of inertia on the output shaft of the reducer (kg•m ) 2 (3) Acceleration torque Ta and deceleration torque Tb I r : Load moment of inertia on the output shaft of the reducer (kg•m 2) Acceleration torque Ta...

2. Sizing procedure (1) (1) Calculate the reduction ratio i. (2) Calculate the average output torque. (3) fs: Series factor GMTK･HMTK : 1.4 EWJMK･EWMK･SWJMK･SWMK : 1.0 Average torque Tave.< rated torque of the output shaft of the reducer Maximum torque Ta< rated torque of the output shaft of the reducer × series factor fs Tb< rated torque of the output shaft of the reducer × series factor fs (4) Calculate nave., the average output shaft speed. Input speed (r/min) (6) Check the load time percentage. Only for worm gear heads t1＋t 2+t3 Load time percentage %ED= ×100 tt nT× i < maximum input speed...

 Motor Mount Codes (Hypoid and Helical Gear Heads) The dimensions corresponding to the servo motors of various companies are shown as mount codes. The product has been set with the capacities of each motor as standards, but be sure to use the product within the transfer capacity range of each gear head. Note) The mount code interaction tables are representative examples that are current as of April 2019. It may be possible to support servo motors not shown in the tables, so contact us for details. Note) The servo motor specifications may be changed depending on the situation of the motor manufacturer,...
