Gearbox efficiency

This is an overview to gear efficiencies, valid for all our gearbox sizes,
exceptionally:.

Gearbox sizes UGO,UGP,UGR,UGV (Stegmann types) are specified separate,
see catalogue.

The values are only a rough recommendation for calculation of torques.

They can differ depending on lubrication, temperature, lifetime and other influences.
