Description

Przedmiotem wynalazku jest element urzadzenia, majacy wytoczenie dla osadzenia w nim zewnetrz¬ nego pierscienia lozyska tocznego, przy czym wspólczynnik rozszerzalnosci elementu urzadzenia jest wiekszy niz wspólczynnik rozszerzalnosci pierscienia zewnetrznego.The subject of the invention is an element of the device, having an embossing to embed it outside of the rolling bearing ring, where coefficient of expansion of a device element is greater than the coefficient of expansion the outer ring.

Materialy lozysk i elementów urzadzenia, w któ¬ rych te lozyska sa osadzone, jak na przyklad czes¬ ci obudowy i tym podobne, maja rózne wspólczyn¬ niki rozszerzalnosci. Poniewaz na ogól temperatury podczas pracy tych urzadzen nie sa stale i podle¬ gaja duzym wahaniom, wystepuja trudnosci od¬ nosnie osadzenia lozysk tocznych zwlaszcza wtedy, gdy material elementów urzadzenia ma wiekszy wspólczynnik rozszerzalnosci niz material pierscie¬ ni zewnetrznych. Tego rodzaju duze wahania tem¬ peratury wystepuja na przyklad w przypadku sprzegiel hydraulicznych (sprzegiel Fóttingera), które wystawione sa w czasie pracy na dzialania temperatur zawartych miedzy 20°C i 150°C. Po¬ niewaz ich obudowy wykonane sa z aluminium, a do wykonania zewnetrznych pierscieni lozysk tocznych uzywa sie stali, której wspólczynnik roz¬ szerzalnosci wynosi tylko polowe wspólczynnika rozszerzalnosci aluminium, wystepuja czesto, przy wyzszych temperaturach i zaleznie od doboru pa¬ sowania, luzne osadzenie pierscienia zewnetrznego.Materials of the bearings and components of the device in which some of these bearings are embedded, for example, these housings and the like have different coefficients No expansion. Because in general temperature during the operation of these devices, they are not constantly and not watered gaja large fluctuations, there are difficulties in rest the bearing seats of rolling bearings, especially when when the material of the machine components is larger expansion coefficient than the ring material no external. Such large fluctuations in temperature There are conditions, for example, in the case of hydraulic clutch (Fóttinger clutch), which are exposed to activities during the work temperatures between 20 ° C and 150 ° C. Mon. because their housings are made of aluminum, a for making the outer bearing rings steel, whose coefficient of dissolution the width is only half the factor aluminum expansions often occur with higher temperatures and depending on the selection of steam slings, loose fitting of the outer ring.

Znane jest unikanie tych wad przez wylanie obudowy stalowa lub zeliwna tuleja, w celu osa¬ dzenia w niej pierscienia zewnetrznego. Wada te¬ go sposobu jest z kolei wysoki koszt, tak, ze to rozwiazanie stosowane bywa tylko w specjalnych przypadkach.It is known to avoid these drawbacks by pouring steel or cast iron bushing for the purpose of the housing the outer ring in it. The disadvantage too its way is in turn high cost, yes that is the solution is used only in special cases cases.

Znane jest równiez otaczanie pierscienia ze- wnetrznego falistym wiencem ze stali sprezynowej, w celu uzyskania tym sposobem sprezystego pola¬ czenia pierscienia zewnetrznego z obudowa. W praktyce okazalo sie jednak, ze wystepuja tu nie¬ dopuszczalne wieloboczne odksztalcenia zewnetrz- io nego pierscienia lozyska, które pociagaja za soba nieprawidlowosci ruchu obrotowego.It is also known to surround the ring with internal wavy spring steel ring, in order to obtain an elastic field in this way connecting the outer ring with the housing. IN in practice, however, it turned out that there are no here permissible external polygonal deformations and the bearing ring that pulls along rotational anomalies.

U podstaw wynalazku lezy wiec zadanie zapew¬ nienia mocnego osadzenia pierscienia zewnetrzne¬ go, niezaleznego od temperatur roboczych, w przy- padku elementów urzadzen, których wspólczynni¬ ki rozszerzalnosci sa wieksze niz wspólczynniki, roz¬ szerzalnosci zewnetrznych pierscieni lozysk tocz¬ nych. Tego rodzaju elementy urzadzen wykonane sa na przyklad z aluminium, poliamidów itp.It is therefore the task of the invention to provide to ensure that the outer ring is firmly seated irrespective of the operating temperatures, for of the equipment components whose effect and the expansions are greater than the coefficients, dil the width of the outer rings of the rolling bearings all. This kind of device components are made are for example made of aluminum, polyamides etc.

W mysl wynalazku, zadanie to zostalo rozwiaza¬ ne w ten sposób, ze w wytoczeniu osadzony jest element pierscieniowy, którego wspólczynnik roz¬ szerzalnosci jest wiekszy niz wspólczynniki rozsze¬ rzalnosci elementu urzadzenia i pierscienia ze- wnetrznego. Osiagnieto tym sposobem to, ze przy wzroscie temperatury element pierscieniowy roz¬ szerza sie silniej niz pierscien zewnetrzny i czesc urzadzenia, w której jest osadzony. W wyniku po¬ wyzszego, przy wyzszych temperaturach wywiera on silny nacisk zarówno na pierscien zewnetrzny, 92 54892 548 jak i na czesc urzadzenia; tak, ze pierscien ze¬ wnetrzny jest przytrzymywany w sposób nie po¬ zwalajacy na jego poruszenie i utworzenie sie osa¬ dzenia luznego nie jest juz mozliwe.According to the invention, this task has been solved in such a way that it is embedded in the extrusion a ring element whose dilution factor is the width is greater than the expansion factors of the device element and the ring internal. It was achieved in this way that temperature rise ring element dil it spreads more powerfully than the outer ring and part device in which it is embedded. As a result of higher, at higher temperatures it exerts he has a strong emphasis on both the outer ring, 92 54 892 548 as well as for the part of the device; yes, with the ring the inside is held firmly lagging behind its movement and the formation of a wasp slack operation is no longer possible.

W celu unikniecia osiowego przesuwania sie ele- anentu pierscieniowego, wewnetrzna sciana wyto¬ czenia moze wedlug wynalazku miec obwodowe wybranie dla osadzenia w nim tego elementu.In order to avoid axial shifting of the ring anent, inner wall lining The connections may, according to the invention, have peripheral selecting this element to embed in it.
