Description
Vynález sa týká spOsobu montáže masívnych klietok valivých ložísk.The invention relates to a method for the assembly of solid roller bearing cages.
Masivně klietky valivých ložísk, najma vačších priemerov sa vyrábajú spravidla z dvoch dielov.Massive cages of rolling bearings, of the smallest diameters, are usually made of two parts.
Je známy spOsob spojovania oboch Saští klietok pomocou rybinového spojenia. Tento sp6sob má ale viaceré nevýhody. Pretože rybinový spoj je třecí, mňže v dOsledku vibrácií klietky a nérazov valSekov na ňu pri prevádzkovom zatažení d6jsť k uvoTneniu spojov a tým k vzájemnému pootočeniu oboch Saští klietky v tangenciálnom smere. Takto uvoTnené spoje mSžu spOsobovat ňalšie vibrácie klietky, zvýšit hlučnost ložiska, znížit tuhost klietky, připadne viest k celkovému porušeniu klietky. Možnost uvoTnenia spojov klietky je vyššia najma pri klietkach z hliníkového materiálu, vzhTadom na vaSšiu možnost otlašenia tohoto materiálu. Možnost uvoTnenia takéhoto spoja je vyššia při zohriatí sa ložiska v prevádzke. Navýše kli etka s rybinovými spojmi má vzhTadom na horeuvedené skutoSnosti menšiu tuhost ako nitovaná. Aby rybinový spoj mal dostatoSnú mechanická pevnost na všetkých spojoch klietky, vyžaduje sa velmi přesné licovanie s malými toleranciami ako samostatného rybinového spoja, tak aj So do kvality prstencov klietky. V podmienkach hromadnej výroby sa vzhTadom na malá tvarová tuhost dielcov a vzhTadom na prevažne hliníkový materiál takéto tolerancie dajá len veTmi obtiažne dosiahnut.It is known to connect the two cages with a dovetail connection. However, this method has several disadvantages. Since the dovetail joint is frictional, the joints can become loosened and thus rotate relative to each other in the tangential direction due to the vibration of the cage and the impact of the rollers on it during operational loading. Such loosened joints can cause further cage vibrations, increase bearing noise, reduce cage stiffness, or lead to overall cage failure. The possibility of loosening the cage joints is higher, in particular for aluminum cages, because of your ability to harden this material. The possibility of releasing such a joint is higher when the bearing is warmed up during operation. In addition, the dovetail joint cage has a lower stiffness than riveted with respect to the above. In order for the dovetail joint to have sufficient mechanical strength on all cage joints, very precise licensing with small tolerances is required both for the single dovetail joint and for the cage ring quality. Due to the low shape rigidity of the parts and to the predominantly aluminum material, such tolerances are difficult to achieve under mass production conditions.
Uvedené nevýhody do znaSnej miery odstránia sa spSsobom montáže masívnych klietok valivých ložísk, kde stykové plochy nákružku s telesa klietky sá mechanickým obrábaním upravené na tvar zámku rybiny a podobné, pri ktorom sa nákružok ohřeje na teplotu, potřebná na zvaSšenie jeho priemeru, nasunie sa voTne na teleso klietky a klietka ložiska sa nechá vychladnut na teplotu miestnosti, podstata ktorého spočívá v tom, že v miestach styku telesa klietky s nákružkom sa klietka zvarí prémiovaným zvarom s vysoko koncentrovaným zdrojom tepla elektronovým alebo lasrovým lúíom s teplotným príkonom do miesta zvárania od 60 do 120 J/mm“1.These drawbacks are largely eliminated by the installation of massive roller bearing cages, where the contact surfaces of the collar with the cage body are machined to a dovetail lock shape and the like, in which the collar is heated to a temperature needed to increase its diameter, the cage body and the bearing cage are allowed to cool to room temperature, which consists of welding the cage with a premium weld with a highly concentrated heat source by means of an electron or laser beam with a heat input to the welding point of 60 to 120 J / mm ' 1 .
Použitím spSsobu podl’a vynálezu sa dosiahne vyšila pevnost. Mechanická Sasť spoja ·ρβsobí proti sile, ktorá pri prevádzke ložiska pOsobí v axiálnom smere ložiska na odtrh přiloženého krúžku, zvarový spoj okrem toho istého pdsobenia pflsobí proti imykovým silám, ktoré mOžu spflsobiť vzájomná pootoSenie oboch spojovaných Saští.By using the method according to the invention, strength is achieved. The mechanical joint of the joint acts against the force which, in the course of the bearing operation, acts in the axial direction of the bearing to tear off the enclosed ring.
Spojom, vyhotoveným podl’a vynálezu, sa přídavné ohybové naméhanie zníži na minimum alebo úplné vylúči, pretože os valSekov, kde pflsobí sila, je přibližné v střede medzi zvéraným a rybinovým spflsobom. Ďalej sa dosiahne zváSienie celkového nosného prlerezu spoja voíi doteraz používaným spojom.The joint made according to the invention reduces the additional bending stress to a minimum or eliminates it completely, since the axis of the cylinders where the force is applied is approximately in the middle between the clamped and dovetail method. Furthermore, an increase in the overall bearing cross section of the joint is achieved with respect to the joint used up to now.
Na pripojenom výkrese je znázorněný příklad prevedenia zvaru na masívnej klietke valivého ložiska.The attached drawing shows an example of a weld design on a massive roller bearing cage.
Po vložení valivých Saští ložiska A do telesa 2 klietky sa ohřeje nékružok i na teplotu, pri ktoréj sa jeho priemer zvaSší natolko, aby ho bolo možné volné nasunúť na teleso 2 klietky. Teplota ohřevu je závislá na konstrukci! spoja a druhu použitého materiálu na výrobu klietky. Používajú sa ocel’, hliník a zliatlny neželezných kovov. Potom sa klietka ložiska nechá vychladnúť na teplotu miestnosti. Po ochladnutí a zmrštení nákružku J. a jeho zasunutí sa do stykovéj plochy telesa 2 klietky vytvoří sa velmi dobrý mechanický spoj. Konětrukcia úprav a prlemerov plflch spoja sa volí tak, aby po vytvoření spoja vzniklo v ňom určité napatie. Velkost predpatia závisí na drsnosti opracovania povrchu stykových plflch, ako i druhu použitého materiálu. Takto vyhotovený spoj sa v mieste styku telesa 2 klietky s nákružkom J. zvarí přerušovaným zvarom oblúkovou metodou s teplotným príkonom do miesta zvárania od 60 do 120 J/mm-'.After insertion of the roller bearings A into the cage body 2, the annular is heated up to a temperature at which its diameter is increased enough to allow it to slide freely onto the cage body 2. The heating temperature depends on the design! joint and type of cage used. Steel, aluminum and non-ferrous non-ferrous metals are used. The bearing cage is then allowed to cool to room temperature. After cooling and shrinking of the collar J and its insertion, a very good mechanical joint is formed in the contact surface of the cage body 2. The design of the adjustments and the diameters of the splice joint is chosen so that a certain tension is created after the joint is formed. The amount of prestressing depends on the roughness of the surface treatment of the contact plates and the type of material used. The thus made connection is at the contact of the body 2 of the cage is welded to the collar J. intermittent arc welding method with a thermal input of the welding points 60 and 120 J / mm - ".
