Description
Vynález se týká valivého uložení, zejména náprav kolejových vozidel, například lokomotiv a vozů,The invention relates to rolling bearings, in particular to axles of rail vehicles, for example locomotives and wagons,
Nápravy kolejových vozidel jsou zpravidla uloženy ve dvojici soudečkových naklápěcích ložisek, ve dvojici kuželíkových loži-, sek, anebo ve dvojici válečkových ložisek na obou čepech nápravy.The axles of rail vehicles are usually mounted in a pair of spherical spherical roller bearings, in a pair of tapered roller bearings, or in a pair of roller bearings on both axle pins.
Při použití válečkových ložisek pro uložení čepů nápravy jsou ložiska opatřena bu3 masivní nýtovanou klecí, vedenou na valivých tělískách, nebo masivní okénkovou klecí, vedenou na nákrůžcích vnějšího kroužku, anebo masivní nýtovanou klecí, vedenou na valivých tělískách, přičemž jsou nýty vytvořeny přímo ze stojin klece.When using cylindrical roller bearings, the bearings are provided with either a massive riveted cage guided on rolling elements, a massive window cage guided on the outer ring rings, or a massive riveted cage guided on the rolling elements, the rivets being formed directly from the cage webs. .
Všechny uvedené příklady uložení jsou technologicky náročné a konstrukčně složité. Při· použití klece s nýty dochází k destrukci nýtů vlivem rozdílných tepelných dilatací nýtů a stojiny klece, nebo nedostatečným provedením nýtového spoje, popřípadě vlivem dynamických rázů v uložení.All examples of mounting are technologically demanding and structurally complex. When using a rivet cage, rivets are destroyed due to different thermal dilatations of the rivets and the cage web, or insufficient rivet connection, or due to dynamic shocks in the bearing.
