Abstract
Description
Vynález se týká zařízení pro os^ivý.ppsuv v rotační součásti stroje vůči pevné 'sou- 1 části stroje, v níž je rotující souČhŠt urážena. Řeší problém jednoduchého a jp£esného axiálního seřizování rotující součásti stroje z důvodů výrobních i funkčních.The invention relates to a device for os ^ ivý.ppsuv rotary machine component relative to a fixed '1 At the same part of the machine in which the rotating souČhŠt insulted. It solves the problem of simple and precise axial adjustment of the rotating machine part for production and functional reasons.
Dosud se pro axiální seřizování rotujících částí strojů používá buď vkládání různě silných podložek, nebo vkládání různého počtu podložek na hřídel, náboj, nebo všeobecně axiálně mezi rotující a pevnou část stroje. Tato manipulace je obtížná a časově náročná. Často se axiální seřizování neprovádí vůbec, což však klade nároky na přesnost výroby a zvyšuje výrobní náklady. □ některých přesných strojů, jako např. u přesných podtlakových secích strojů, je pak přesné osové seřízení stroje jednou ze základních podmínek správné funkce výsevního ústrojí a je nutno přesně axiální mezeru ve výsevním ústrojí vymezit, aby nemohla malá semena propadávat a špičatá semena zakliňovat. Vymezení této vůle bylo dosud velmi obtížné a záviselo jak na přesnosti výroby, tak na popsaném časově náročném osovém seřízení. Zvyšovaly se tím výrobní náklady a při méně pečlivé práci pak klesala kvalita práce stroje.Until now, either the insertion of different thickness washers or the insertion of a different number of washers onto the shaft, hub or generally axially between the rotating and fixed part of the machine has been used for axially adjusting the rotating machine parts. This handling is difficult and time consuming. Often, axial adjustment is not performed at all, but this places demands on manufacturing accuracy and increases production costs. □ Some precision machines, such as precision vacuum sowing machines, then precise axial alignment of the machine is one of the basic conditions for proper sowing function and the axial gap in the sowing unit must be precisely defined to prevent small seeds from dropping and spiked seeds. The definition of this clearance has so far been very difficult and has been dependent on both the manufacturing accuracy and the time-consuming axial alignment described. This increased production costs and, with less careful work, the quality of the machine's work decreased.
Zařízení pro osový posuv rotační součásti stroje podle vynálezu tyto nevýhody a nedostatky odstraňuje. Jeho podstata spočívá v tom, že pevné těleso stroje je opatřeno závitem pro spojení s pouzdrem, v němž je svým vnějším kroužkem pevně uloženo ložisko, jehož vnitřní kroužek je pevně uložen na otočné části stroje.The axial displacement device of the rotary component of the machine according to the invention removes these disadvantages and drawbacks. It consists in that the fixed body of the machine is provided with a thread for connection to a housing in which a bearing is fixed by its outer ring, the inner ring of which is fixed on the rotating part of the machine.
Zařízení pro osový posuv rotační součásti stroje vůči pevné součásti stroje podle vynálezu zajišťuje axiální seřizování velmi rychle a přesně s nízkými výrobními náklady. Tím značně přispívá i к přesnosti práce strojů a usnadňuje a zlevňuje přitom i samotný výrobní proces.The device for axial displacement of the rotating machine part with respect to the fixed machine part according to the invention ensures axial alignment very quickly and precisely at low production costs. This greatly contributes to the precision of the machines and makes the production process easier and cheaper.
Příklad provedení zařízení podle vynálezu je ve schematickém osovém řezu znázorněn na připojeném výkrese.An exemplary embodiment of the device according to the invention is shown in schematic axial section in the attached drawing.
