M 2max, G – Maximum output torque of the gearbox components

This torque must not be exceeded during operation. It is permissible for a maximum of 30000 revolutions of the output shaft. An endurance strength configuration of the gearbox becomes necessary, if the output torques up to M2max, G are used (see Configuration Manual).

M 2Em.Off – Emergency Off output torque of the gearbox components

The Emergency Off torque can be tolerated a maximum of 1000 times within the gearbox service life without causing unacceptable damage to the gearbox. This code can be used to check whether the torques, caused by very rare operating faults, can damage the gearbox.

η G – Efficiency of the gearbox components under full load

The exact values for the efficiency are, to some extent, dependent on the frame size of the mounted motor and can be found in the data sheet resulting from the configuration on the Siemens Product Configurator.
In the partial load range, especially when the gearbox is cold, the efficiency of the gearbox is always lower than at operating speed.
The gear losses are already taken into account in the characteristic curves and in the following characteristic data of the geared motor or its components: M2,0, M2,max, M0,M, Mmax,M
A reduction of this characteristic curve and the characteristics on efficiency is not necessary.

C T2 – Torsional rigidity of the gearbox (related to the output)

The exact values for the torsional rigidity are dependent on the motor-gearbox combination and can be found in the data sheet resulting from the configuration on the Siemens Product Configurator.

φ 2 – Torsional backlash of the gearbox on the gearbox output

Permissible shaft loading capacity

The limit values shown for the bearing load refer to equivalent forces to be determined mathematically, whose effect is equivalent to the forces occurring in the load profile.
They only apply to radial and axial loads. Axial forces up to maximum FA = 0.4 × FR are permissible in case of superimposition.
They apply to the output speed of 100 rpm and in case of radial force for a force application point in the center of the shaft or for centrally applied axial force. For other speeds or force application points, the permissible radial forces must be obtained from the radial force diagrams of the Configuration Manual.

m G - Weight of the gearbox components

The weight of the assigned motors and the total weight of the geared motors are in the data sheet resulting from the configuration of the motor or the geared motor in the Siemens Product Configurator.
