Abstract
Vynález sa týká rebrovanej plášťovej kostry pre chladenie elektrických strojov točivých. Kostra je vytvořená skruženým plechoma rebrovaným plášťom s rébrami vytvořenými zlisovanými priehybmi plechu, pričom skružený plechje svojou stykovou plochou připevněný k vnútornej ploché rebrovaného plášťa nerozoberateFným spojom. Chladiace rebrá rebrovaného plášťa sú na stykovej ploché stien rebra spojené nerozoberatelným spojom. Toto spojenie zvýši tvarovú tuhosť rebrovaného plášťa.The invention relates to a ribbed casing frame for cooling rotating electrical machines. The frame is formed by a rolled sheet metal and a ribbed casing with ribs formed by pressed sheet metal bends, the rolled sheet metal being attached by its contact surface to the inner flat surface of the ribbed casing by a non-detachable joint. The cooling ribs of the ribbed casing are connected by a non-detachable joint to the contact surface of the rib walls. This connection increases the dimensional rigidity of the ribbed casing.

Vynález sa týká rebrovanej plášťovej kostry pre chladenie elektrických strojov točivých.The present invention relates to a ribbed skeleton for cooling electrical rotating machines.
Kostra je vytvořená skruženým plechom a rebrovaným plášťom s rébrami vytvořenými zlisovanými priehybmi plechu, pričom skružený plech je svojou stykovou plochou připevněný k vnútornej ploché rebrovaného plášťa nerozoberatelným spojom. Chladiace rebrá rebrovaného plášťa sú na stykovej ploché stien rebra spojené nerozoberatelným spojom. Toto spojenie zvýši tvarovú tuhost’ rebrovaného plášťa. 2.19172The carcass is formed by a bent sheet and a ribbed casing with crimped sheet metal deflections, wherein the bent sheet is attached to the inner flat ribbed face by a non-detachable joint by its contact surface. The ribs of the ribbed jacket are connected to a non-detachable joint on the rib flat wall. This connection will increase the stiffness of the ribbed jacket. 2.19172
Vynález sa týká rebrovanej plášťovej kostry pre chíadenie elektrických strojov točivých pozostávajúcích z plášťa tvořeného skruženým plechom, na ktorom sú chladiace rebrá tvořené vytvarovanými zlisovanými priehybmi plechu a skruženého plechu.BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a ribbed skeleton for driving electrical rotary machines consisting of a skirt formed by a bent sheet, on which the cooling ribs are formed by molded crimped sheet and bent sheets.
Doteraz používané kostry v zatvorenom vyhotovení pre elektrické stroje točivé sa vyznačujú niektorými technickými nedostatkami. Kostra tvořená hladkým plášťom bez rebier má malú chladiacu plochu. Zváčšenie chladiacej plochy realizované přivařením rebier z pásovej ocele je pracné a náročné na také vyhotovenie zvarov, ktoré zaručujú postup tepla medzi plášťom a rebrami. Plechová kostra s rebrami vytvořenými zvlněným plechom sa , používá pre stredne velké motory s dvorná chladiacimi okruhmi. Rebrovaná kostra s plášťom tvořeným skruženým plechom, na ktorom sú chladiace rebrá vytvořené zlisovanými priehybmi plechu nezaručuje dostatočnú kruhovitost, čo spósobuje nedostatočný přestup tepla medzi statorovým zvázkom plechov a plášťom kostry. Realizácia zvarového oleja stien rebier metodou odporového zvárania alebo zavarenie paty rebra oblúkovým zvarom sú technologicky a energeticky vefmi náročné a nezaručujú dostatočnú tvarovú přesnost’ a tuhosť kostry pri nalisovaní statorového zvázku elektrického stroja točivého, čo znemožňuje vytvorenie dostatočnej stykovej plochy medzi statorovým zvázkom a plášťom kostry a tým zhoršuje 1 odvod tepla zo statorového zvázku pri zatažení elektrického stroja točivého.The previously used closed-end skeletons for electrical rotary machines have some technical drawbacks. The skeleton made of a smooth casing without ribs has a small cooling surface. Welding of the cooling surface by welding the ribs of the strip steel is laborious and difficult to produce welds, which guarantee the heat transfer between the jacket and the ribs. The sheet metal skeleton with ribs formed by corrugated sheet metal is used for medium sized engines with a cooling circuit. A ribbed carcass with a shell formed by a bent sheet on which the cooling ribs are formed by crimped sheet deflections does not guarantee sufficient roundness, which causes insufficient heat transfer between the stator sheet bundle and the carcass casing. The implementation of welded-on ribbed wall oil by resistive welding or arc welding of the rib heel is technologically and energy-intensive and does not guarantee sufficient shape accuracy and rigidity of the carcass when pressing a stator tie of a rotary electric machine, which prevents the creation of a sufficient contact area between the stator bundle and the skeleton shell and thereby deteriorating the heat dissipation from the stator bundle when the electric rotary machine is retracted.
