Gearboxes with ventilation
Gearbox size 04 and gearbox type GKR
No ventilation is required for these gearboxes.
Gearbox size 05 to 07
Special measures are not usually required when using these
gearbox sizes.
In borderline cases, e.g. at drive speeds >2000 rpm, we
recommend that breather elements are used. We can
supply these elements if required.
Gearbox size 09 to 14
Ventilation units are always supplied with these gearbox
sizes.
Special precautions for mounting position C (motor on top)
We recommend that an oil compensation reservoir is
always used with gearbox sizes 09 to 14 in this mounting
position. This reservoir can be purchased as an option.
See technical data for illustrations and dimensions
(Chapter 3…7).
It is not required at high ratios or low input speeds.
