Gearboxes with v<strong>en</strong>tilation<br />

Gearbox size 04 and gearbox type GKR<br />

No v<strong>en</strong>tilation is required for these gearboxes.<br />

Gearbox size 05 to 07<br />

Special measures are not usually required wh<strong>en</strong> using these<br />

gearbox sizes.<br />

In borderline cases, e.g. at drive speeds >2000 rpm, we<br />

recomm<strong>en</strong>d that breather elem<strong>en</strong>ts are used. We can<br />

supply these elem<strong>en</strong>ts if required.<br />

Gearbox size 09 to 14<br />

V<strong>en</strong>tilation units are always supplied with these gearbox<br />

sizes.<br />

Special precautions for mounting position C (motor on top)<br />

We recomm<strong>en</strong>d that an oil comp<strong>en</strong>sation reservoir is<br />

always used with gearbox sizes 09 to 14 in this mounting<br />

position. This reservoir can be purchased as an option.<br />

See technical data for illustrations and dim<strong>en</strong>sions<br />

(Chapter 3…7).<br />

It is not required at high ratios or low input speeds.<br />

Please contact L<strong>en</strong>ze if this affects your application.<br />
