Abstract
Zariadenie pre uloženie středných ložísk klapiek netlakových potrubí parných kotlov. Riešenie sa týká uloženia středných ložísk klapiek netlakových potrubí, v ktorých sa otáča hriadel klapky a jeho podstatou je pevné spojenie ložiska klapky a rámom klapky prostredníctvom púzdra a poistného krúzku, pričom je zabezpečená správná poloha hriadela a listu klapky. Vynález je možno využit všade tam, kde u nizkootáčkovýoh zariadení nie je možné prevádzat údržbu (domazávanie) ložisk po čas prevádzkyDevice for mounting the central bearings of non-pressure pipe valves of steam boilers. The solution concerns the mounting of the central bearings of non-pressure pipe valves in which the valve shaft rotates and its essence is a solid connection of the valve bearing and the valve frame by means of a bushing and a retaining ring, while ensuring the correct position of the shaft and the valve blade. The invention can be used wherever it is not possible to perform maintenance (relubrication) of the bearing during operation in low-speed devices
Description
Vynález sa týká zariadenia pre uloženie středných ložísk klapiek netlakových potrubí parných kotlov,BACKGROUND OF THE INVENTION 1. Field of the Invention
Doteraz sa středné ložiska klapiek netlakových potrubí do rámu klapky priohytávali komplikovaným púzdrom a tesniacim za riadením. Taktlež samotné ložiska používané pro klapky neplnili v praxi svoju fuňkciu, pretože vplývom malej vole m edzi ich častami a nevyhovujúcím utěsněním priestoru pre uloženie ložiska dochádzalo k ich zasekávaniu· Nevýhody tohto riešenia spočívajú najma v tom, že zariadenie pre uloženie středných ložísk klapiek je komplikoV V M váné a tým i drahé, dalšia nevýhoda spočívá v nespolehlivosti samotných ložisk v prevádzke, pretože ich údržba nie je možná a v případe ich zaseknutia je oprava zdlhavá a pracná.Until now, the middle bearings of the non-pressure piping flaps into the damper frame have been caught by a complicated housing and sealing behind the steering. Also, the bearings used for the dampers themselves did not function in practice, because the stubborn small clearance between the parts and the poor sealing of the bearing compartment caused them to jam. Another disadvantage lies in the unreliability of the bearings themselves in operation, because their maintenance is not possible and in case of their jamming the repair is lengthy and laborious.
Uvedené nedostatky sú odstraněné zariadením pre uloženie středných ložísk klapiek netlakových potrubí parných vThe above drawbacks are eliminated by a device for accommodating middle bearings of non-pressure steam duct flaps
kotlov podlá vynálezu, ktorého podstatou je, že nerezové ložiska sú prostrednictvom púzdra a poistného krúžku jednov ducho a spolahlivo pevne spojené s ramenom klapky, pričom vof the boilers according to the invention, the essence of which is that the stainless steel bearings are firmly and reliably connected to the damper arm by means of a sleeve and a snap ring.
je zabezpečena správná poloha a funkčnost hriadela a listu klapky, vcorrect position and functionality of the shaft and damper blade is assured;
Pokrok dosiahnutý zariadením pódia vynálezu spočívá najma v tom, že umožňuje jednoduchým sposobom spolahlivo uložit středné ložiska klapiek netlakových potruv bí bez nutnosti ich dalšej údržby, oprav a utěsněnia.The progress achieved with the device according to the invention is, in particular, in the simple way of reliably accommodating the central bearings of the non-pressure flaps without the need for further maintenance, repair and sealing.
Na pripojenom výkr ese je znázorněné v řeze zariadenie podlá vynálezu.The device according to the invention is shown in cross-section in the accompanying drawing.
Zariadenie je tvořené púzdrom 1 a ložiskem 2, ktoré je poistným krúžkom £ zaistené v ráme klapky 4.The device consists of a housing 1 and a bearing 2, which is secured by a retaining ring 6 in the frame of the flap 4.
Ložisko 2 umožňuje hriadeiu klapky £ s lištami klapky 6 otáčavý pohyb pri otváraní-zatváraní klapky.The bearing 2 allows the flap shaft 6 with the flap bars 6 to rotate when the flap is opened-closed.
