Abstract

Řešení ae týká rotoru elektrického stroje s podélnými ventilačními, cívkovými a dalšími drážkami. Cíl řešení - zvýšení provozní spolehlivoati rotoru vyloučením poškození hřídelů třecí únavou. S tímto cilam v rotoru, mající hřídel a podélnými ventilačními drážkami, jaou drážky zčáati po délce uzavřeny klíny, přičemž mezi opěrnými plochami klínu a plochami hřídelů uloženy izolační vložky z ftoroplastu vyztuženého skelnou tkaninou.The solution relates to a rotor of an electric machine with longitudinal ventilation, coil and other grooves. The aim of the solution is to increase the operational reliability of the rotor by eliminating damage to the shafts by frictional fatigue. With this aim, in a rotor having a shaft and longitudinal ventilation grooves, the grooves are closed along their length by wedges, with insulating inserts made of fluoroplastic reinforced with glass fabric being placed between the supporting surfaces of the wedge and the surfaces of the shafts.
