Application scenarios

Selection guide

The following headings contain the principles of selecting reducers and how to use them correctly. For specific values, please refer to the corresponding chapter

Output torque

1.1 Rated torque M_n2[Nm]

The value measured when the torque acts on a continuously and smoothly running reducer and the working coefficient f_s=1.

1.2 Required torque T_2r[Nm]

Based on actual needs, the value is equal to or less than the rated torque M_n2 of the reducer.

1.3 Calculate torque T_2c[Nm]

Useful when choosing a reducer. It needs to consider the actual torque M_r2 and the working coefficient f_s, which is calculated by the following relationship:

Power

2.1 Rated input power P_n1[kW]

The power (kW) value of the reducer during safe operation is listed in the parameter table. It is obtained when the speed is equal to n1 and the working coefficient f_s=1.
2.2 Rated input power P_n2[kW]

The output power value of the reducer can be calculated with the following formula:

Work factor [f_s]

3.1 Rated torque M_n2[Nm]

The working coefficient (f_s) of the reducer mainly depends on the operating conditions of the reducer. In order to select the most suitable working environment coefficient for the correct combination, the following factors must be considered :
