Description

Vynález ae týká zařízení pro bezvřetenové předení a rotorem spřádací komory umístěným ve skříni a podtlakovým prostředím a který je prostřednictvím hnacího hřídele a ložiskového pouzdra pružně uložen v nástavci skříně.The invention relates to an open-end spinning device and a rotor of a spinning chamber disposed in a housing and a vacuum environment and which is resiliently seated in the housing extension via a drive shaft and bearing bush.

Známé zařízení pro bezvřetenové předení má rotor spřádací komory uchycen prostřednictvím svého náboje na hřídeli. Hřídel je uložen v ložiskovém pouzdru, které je nehybně uspořádáno v nástavci skříně. V místě, kde náboj rotoru-spřádací komory prochází otvorem ve stěně skříně do nástavce, je náboj; opatřen labirintem, který při minimální vůli mezi nábojem a otvorem skříně zajišťuje oddělení prostorů s rozdílnými tlakovými poměry proti vnější atmosféře. Tím je zejména bráněno narušení tlakových poměrů v prostoru umístění rotoru spřádací komory a docíleno zamezení proudění vzduchu přes ložiskové pouzdro do zmíněného prostoru pro rotor spřádací komory. Vývojem konstrukce uložení ložiskového pouzdra v nástavci skříně se docílilo uložení ložiskového pouzdra hřídele rotoru v pružném pouzdru, tlumícím dynamické rázy a umožňující výkyv hřídele rotoru spřádací komory.The known open-end spinning device has the rotor of the spinning chamber secured by its hub on the shaft. The shaft is housed in a bearing bush which is fixed in the housing extension. At the point where the hub of the rotor-spinning chamber passes through the opening in the housing wall to the extension, there is a charge; equipped with a labirint, which at minimum clearance between hub and housing opening ensures separation of spaces with different pressure ratios against external atmosphere. In this way, the disruption of the pressure conditions in the rotor housing space of the spinning chamber is prevented, and the air flow through the bearing sleeve is prevented from flowing into said rotor chamber of the spinning chamber. By developing the bearing housing bearing design in the housing extension, the bearing housing of the rotor shaft has been accommodated in a flexible housing, damping dynamic shock and allowing the rotor shaft of the spinning chamber to swing.

Tato úprava uložení ložiskového pouzdra v pružném pouzdru si však vynutila zvětšení vůle mezi nábojem rotoru a otvorem ve stěně skříně. Zvětšením vůle mezi labirintem na náboji rotoru a otvorem ve stěně skříně došlo k narušení funkce labirintu, což znamená při-sávání vzduchu z vnější atmosféry do prostoru uložení rotoru spřádací komory. PřitomHowever, this adjustment of the bearing bush housing in the flexible housing has forced an increase in clearance between the rotor hub and the opening in the housing wall. By increasing the clearance between the labirint on the rotor hub and the opening in the cabinet wall, the labirint function is impaired, which means that the air from the outside atmosphere is added to the rotor housing of the spinning chamber. Doing so
