Description

Oblasť technikyTechnical field

Vynález sa týka domazávacej sústavy vysokootáčkového ložiska, najmä bezvretenového dopriadacieho stroja, obsahujúcej puzdro, ktorým je ložisko uložené v pružnom člene, ktorý je uložený v ložiskovom telese, pričom puzdro ložiska, pružný člen aj ložiskové teleso sú vybavené vzájomne sa kryjúcimi prístupovými otvormi, ktorým je priradená dutá priechodka, na strane odľahlej od ložiska uzatvorená zátkou.The invention relates to a regreasing assembly of a high-speed bearing, in particular an open-end spinning machine, comprising a bushing for receiving the bearing in a resilient member which is housed in the bearing housing, the bushing, the elastic member and a hollow grommet associated with a plug on the side remote from the bearing.

Doterajší stav technikyBACKGROUND OF THE INVENTION

Na zaistenie správnej funkcie vysokootáčkového ložiska, najmä vysokootáčkového ložiska spriadacieho rotora bezvretenového dopriadacieho stroja, je nevyhnutné jeho dokonalé mazanie. To je zabezpečené náplňou kvalitného plastického mazadla, ktoré je pre otáčky väčšie ako 60 000 min.'1 v pravidelných intervaloch oživované malým, experimentálne zisteným, množstvom základného oleja použitého mazadla. Tento olej je vstrekovaný do priestoru ložiskových radov alebo medzi ne. Doterajší domazávací systém, napr. podľa ČS AO 198 684, spočíva v tom, že v puzdre ložiska, pružnom člene aj v ložiskovom telese sú vytvorené otvory na prívod mazadla. Otvory v puzdre ložiska sú uzavreté otočnými krytmi, ktoré sa pred domazanim presunú, čím sa odokryje otvor na domazanie a do vnútorného priestoru ložiska je niektorým zo známych riešení, napr. podľa CS AO 248 684, dopravené predpísané množstvo oleja. Potom sa kryty presunú späť a uzavrú otvor na domazanie. Tento spôsob domazávania sa používa pri otáčkach ložiska do 90 000 min'1. Pri otáčkach ložiska nad 90 000 min.'1, napr. podľa ČS PV 1899-91 alebo ČS PV 2545-92 je uloženie ložiska doplnené o zásobník základného oleja použitého plastického mazadla, z ktorého je tento olej dopravovaný do vnútorného priestoru ložiska.In order to ensure the correct functioning of the high-speed bearing, in particular the high-speed bearing of the spinning rotor of an open-end spinning machine, perfect lubrication is necessary. This is ensured by the filling of high-quality grease, which is higher than 60 000 min. 1 at regular intervals revived with a small, experimentally determined amount of the base oil of the lubricant used. This oil is injected into or between the bearing rows. The current relubrication system, e.g. according to CS AO 198 684, there are openings for the lubricant supply in the bearing housing, the elastic member and the bearing housing. The openings in the bearing housing are closed by rotatable covers which are displaced before relubrication, thereby exposing the regreasing opening and one of the known solutions, e.g. according to CS AO 248 684, the prescribed oil quantity delivered. The covers are then moved back and the regreasing opening is closed. This method is used for regreasing bearing speed to 90,000 rpm first At bearing speeds above 90,000 min. ' 1 , e.g. According to CS PV 1899-91 or CS PV 2545-92, the bearing housing is supplemented with a base oil reservoir of the used grease, from which this oil is transported to the inner space of the bearing.

V doterajšom systéme domazávania vysokootáčkového ložiska s otáčkami do 90 000 min.’1 sa často stáva, že otvory v ložisku, v pružnom člene a ložiskovom telese sa navzájom nekryjú a ložisko je preto potrebné na domazanie vyňať zo stroja, čim sa výrazne zvýši prácnosť aj náklady na domazanie. Pokiaľ sa uvedené otvory navzájom kryjú, je možné ložisko domazať v stroji, pričom však hrozí nebezpečenstvo vnesenia nečistôt do vnútorného priestoru ložiska a tieto potom urýchlia jeho výpadok. Vzhľadom na skracovanie domazávacieho intervalu vplyvom zvyšovania otáčok je použitie tohto spôsobu domazávania pri otáčkach ložiska vyšších ako 90 000 min.'1 už problematické.In the prior art relubrication system for high-speed bearings with speeds up to 90,000 rpm. 1, it often happens that the holes in the bearing, the resilient member and the bearing housing do not cover each other, and the bearing therefore needs to be removed from the machine for regreasing, thereby significantly increasing labor and relubrication costs. As long as these holes cover each other, the bearing can be relubricated in the machine, but there is a risk of impurities being introduced into the bearing's inner space, which will then speed up its failure. Due to the shortening of the relubrication interval due to the speed increase, the use of this relubrication method at the bearing speed is higher than 90,000 min. 1 already problematic.

Usporiadanie domazávacieho systému používaného pri otáčkach nad 90 000 min.'1, t. j. usporiadanie so zásobníkom oleja, nezaručuje dostatočnú spoľahlivosť domazania, čo je spôsobené jednak technicky ťažkým zabezpečením po-trebnej veľkosti dávky oleja na domazanie, ale predovšetkým manipuláciou pri prevádzke, keď dochádza k poškodeniu zásobníka oleja, ktoré je ťažké identifikovateľné. Ložisko potom nie je domazávané a v krátkom čase môže byť zničené. Kontrola, či bolo, alebo nebolo ložisko domazané je takmer neuskutočniteľná. Ďalším nedostatkom tohto riešenia je aj relatívne značné zvýšenie ceny tohto uložcnia vysokootáčkového ložiska so zásobníkom oleja. Snahy o kontinuálne domazávanie vysokootáčkového ložiska, ktoré môžu znamenať zásadný prínos sa doteraz nepodarilo prevádzkovo realizovať s uspokojivou spoľahlivosťou.Arrangement of relubrication system used at speeds above 90,000 min. ' 1 , i.e. the arrangement with the oil reservoir, does not guarantee sufficient relubrication reliability, which is due both to the technically difficult provision of the required amount of oil to be relubricated and, above all, to handling during operation when the oil reservoir is damaged which is difficult to identify. The bearing is then not relubricated and can be destroyed in a short time. Checking whether or not the bearing has been relubricated is almost impossible. Another drawback of this solution is also the relatively significant increase in the cost of this high-speed bearing with oil reservoir. Efforts to continuously relubricate high-speed bearings, which may represent a significant benefit, have not yet been realized with satisfactory reliability.

Cieľom vynálezu je odstrániť alebo aspoň minimalizovať nevýhody doterajšieho stavu techniky.It is an object of the invention to overcome or at least minimize the disadvantages of the prior art.
