6.5 Limiting Temperature Curves to Determine Higher S1-Speed
6.5.1 General
Special applications (e.g. printing sector) require higher S1-speed than given
in the technical data. The GTE gearboxes fulfill these requirements at an ac‐
cordingly reduced output torque individually for every gearbox size and ratio.
The following limiting temperature curves are the basis. They are on trial de‐
termined thermal limiting characteristic curves which illustrate the possible
operating points (S1-input speed/S1-output torque) at maximum thermal load
of the gearbox (temperature increase 60K at 30°C environmental tempera‐
ture) and unhindered air circulation.
The values according to the diagram in Fig. 5-1 have to be reduced if the am‐
bient temperature is higher than 30°C.
The determined limiting characteristic curves are related on an
ambient temperature of 30°C at unhindered air circulation and
fastening on the steel flange, which is more than twice as wide as
the gearbox and has a temperature of 30°C.
Overload of the gearbox due to exceeding
the permitted gearbox housing temperature
of 90°C.
NOTICE
During operation of motor/gearbox combinations in the selected operating
point, please make sure that the permitted gearbox housing temperature of
90°C is not exceeded to avoid a gearbox overload. Depending from the gear‐
box or motor type, more or less heat is induced from the motor into the gear‐
box. For thermal inappropriate mounting it is recommended to check the per‐
mitted gearbox housing temperature after reaching the thermal steady-state.
