11.4.2 Check of the speed load

DSD checks the gearbox with regard to its speed load.

• For all gearboxes or gearbox-motor combinations the max. input speed and the average output

speed are checked.

• The best way to assess the dimensioning of the gearbox is by using the speed/torque diagram.

• For dynamic requirements with regard to geared motors, additional specific checks are required

for these combinations. Taking the thermal load into consideration, a gearbox can be operated

at high speeds for a short time.

DSD carries out these tests with regard to the thermal load.

11.4.3 Radial and axial forces

Dependent on the mechanical construction, radial and axial forces can act on the motor shaft or

driven shaft of the gearbox. Loads due to these forces are not checked in the DSD.
