The technical data is based on a calculated gearbox-lifetime of Lh = 30,000 h
If a gearbox-lifetime of more than 20,000h is required, the technical data, re‐
garding torque and speed have to be reduced by the following diagram.
Fig.6-3: Reduction of the technical data for increased lifetime
The permitted technical operating data may not be exceeded!
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.
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 am‐
bient temperature of 30°C at unhindered air circulation and fasten‐
ing on the steel flange, which is more than twice as wide as the
gearbox and has a temperature of 30°C.
