5.5 Lubrication
At the time of delivery, the gears are conserved with preservation oil. The characteristics of the lubricating grease and oil types
approved by Harmonic Drive® are not changed by mixing with the preservation oil. It is therefore not necessary to remove the
preservation oil completely from the gear components. However, the mating surfaces must be degreased before the assembly,
5.5.1 Grease Lubrication
Illustration 43.1 shows the areas to be lubricated, please also refer to table 38.1. During operation, the 4BNo.2 grease becomes
relatively liquid. Therefore the gear must be sealed as for oil lubrication, when this grease is used. If required, please ask
Harmonic Drive AG for further information.
