Summary

Symbols and Units of Measure

General Informations

Input Rated Power Pn1 [kW]

Applicable power at input related to speed n1 and service factor FS=1.

Output Rated Power Pn2 [kW]

Power transmitted at gear reducer output, calculable with formulas.

Rated Torque at Output Mn2 [Nm]

Torque transmitted at gear reducer output relating to speed n1 and n2.

Required Torque at Output Mr2 [Nm]

Torque corresponding to application requirements.

Calculated Torque at Output Mc2 [Nm]

Torque value used for gear reducer selection.

Reduction Ratio i

Ratio between input and output speeds.

Dynamic Efficiency Rd

Gear reducer efficiency values at full load after running-in.

Angular Speed n1-n2 [min-1]

Speed determined by motorisation type (n1) and reduction ratio (n2).

Service Factor FS

Acceleration Factor of Masses K

Used to determine the type of load, calculated from inertia values.

Thermic Power

Thermic Power Pt [kW]

Indicates the gear reducer's thermic limit, preventing damage to internal components.

Selection
