8103766--5 omges av ett foder 19, 20 som sätts utanpå lagrets ytterring, innan vevaxeln monteras i vevhuset. Fodret visas i fig. 3 och li, där de fyra hålen 21 visar var skruvarna 13 har sin plats .och genomgång. Fodret utgörs av en ram med kortsidor 22 och långsidor 23. På kortsidorna finns förbindelseorgan 24, som håller ihop ramen. Ramhalvorna kan dock behandlas var för sig såsom vidmontering på ramlagren. Ramsidorna tjänstgör även som packning mellan cylinder och vevhus. Egenskapen som packning kan förbätt- ras' genomo utförandet av en låg ås 25 på vardera sidoytan av ramen. Då vevhuset monteras: och skruvarna 13 dras åt tätar ramytorna mot respektive ytor på delarna 10, 12. Elasticiteten i fodret bidrar till att. eventuella ojämnheter i kaviteterna utfylls, då skruvarna dras åt, så att effektiv tätning runt lagren erhålls. Kaviteterna kan därför lämnas olgearbetade sådana de erhålls genom gjutning, eftersom -' redan erhållna toleranser är tillräckligt goda för passning till fodret. Tack vare fodret erhålls även ett jämnt tryck runt om den yttre lagerringen, vilken därigenom inte deformeras da skruvarna dras at. i ' i i Det beskrivna utförandet skall betraktas som exempel på hur uppfinningen kan realiseras. Givetvis kan detaljer flyttas, kompletteras, ersättas eller göras avvikande utan att därigenom uppfinningens grundtanke frångås. oPatentkrav
1. Förbränningsmotor med cylinderdel inkluderande vevhusöverdel, tillverkad av en metallegering, och en vevhusunderdel, tillverkad av plast, samt mellan nämnda delar placerade vevaxellager för motorns vevaxel, k ä n n e t e c k n ia d därav, att en ram med kort- och långsidor (22,23) utgör packning i förbandet mellan vevhusöverdelen och vevhusunderdelen och har på vardera en av två motstående -sidor en ring, bildande foder kring nämnda lager och i monterat tillstånd fastklämd i lagersäten (lli,l5) i vevhusöverdelen respektive vevhusunderdelen (12).
2. Motor enligt patentkravet 1, k ä n n e t e c k n a d därav, att ramen är gjord av högtemperaturbeständig plast, såsom glasfiberarmerad polyester.
3. Motor enligt patentkravet 1, k ä n n e t e c k n a d därav, att ramen är delbar i två delar, vardera innehållande 'enav nämnda ringar.
4. Motor enligt patentkravet 1, k ä n n e t e c k n a d därav, att ramens tätninga- ytor mot respektive vevhusdelar är försedda med åsar (25).
5. Motor enligt patentkravet 3, k ä n n e t e c k n a d därav, att två av ramens varandra motstående sidor är delade och i monterat tillstånd hopfogade medelst hakar "eller dylikt (24).
