Start-up efficiency
During start-up, the start-up efficiency A of a helical-worm
gearbox is lower than its operative efficiency at rated
speed.
The start-up efficiency A must therefore always be
considered when starting under load.

The start-up efficiency is determined by the oil temperature
and the degree to which the tooth faces have been run in.
The values given in the tables are theoretical values and
are valid with a tolerance of ± 10%.
