Abstract

Způsob stanovení natočení břitu lopatky lopatkového stroje za rotace spočívá v tom, že na stator lopatkového stroje se v rovině kolmé na osu rotace lopatkového stroje, která je zároveň různá od rovnoběžné roviny, v níž leží střed (O) natáčení břitu lopatky, umístí senzor (S) průchodu břitu lopatky. Stanoví se časová diference průchodu břitu lopatek v různých otáčkách pod senzorem (S) průchodu břitu lopatky, ze které se následně vypočte hodnota úhlového natočení (φ) břitu lopatky.
