The proposal is a wrong lip seal sets indicated see red

It was also proposed to carry out the central earing o! te!lon" and to #a$e this us

as long as possile" pre!eraly in two parts with an inter#ediate space so that in this

inter#ediate space luricating oil or grease can e stored%

The #ain reason is doule"

on the one hand under a &acuu# o! !riction sur!aces together usually arasi&e

ecause no protecti&e o'ides or nitrides can e !or#ed as a hot spot occurs

The #ounting o! the #ain earings is est done in earing loc$s which in turn are

on a ase plate% These #ain earings ha&e ars with a ore !or the earing

arrange#ent and positioning with circlips which are a!ter asse#ly then olted to the

otto# plate" ut there is a slightly #ore e'pensi&e ut #ore elegant #ethod wherein

the earing #ount has een split in a support with a lid 4cap5" wherein the whole in

the earing arrange#ents can e #ade and then attached with the caps

The #otors are as shown" elow" also secured to the ase plate% Ald !or e'a#ple" a

..## slide #otor is used #ay e an alu#inu# loc$ with a sliding ore .. is used

on one side that is slit" at right angles to this slit&la$ is a olt which cla#ps the

Dee central a'is re2uires the least power unless the te!lon earing would cla#ps or

no lurication and lip seals also insu!!icient lurication% In principle" it is esti#ated that

so#e 9atts su!!ice% The center needs #ore power on the one hand" the lip seals

larger in dia#eter ut the lower losses would also e worse especially i! the a'es
