Abstract

Galet de roulement étanche comprenant un corps de galet monté par des roulements sur un axe. L'axe 1 est creux, porte en creux des chemins de roulement 9, 10 pour deux rangées de rouleaux cylindriques 4, 5 et des gorges 12 pour des joints 13 montés avec précontrainte. Le corps de galet est divisé en deux parties 2, 3, porte deux chemins de roulement extérieurs pour les rouleaux 4, 5 et présente à ses extrémités des rebords intérieurs 14 dont l'alésage 15 coopère avec les joints 13. Les deux parties 2, 3 sont assemblées par emmanchement de deux portions épaulées 16, 17. Application : notamment aux galets pour trains de roulement à chenille.Sealed track roller comprising a roller body mounted by bearings on an axis. The axis 1 is hollow, carries hollow raceways 9, 10 for two rows of cylindrical rollers 4, 5 and grooves 12 for seals 13 mounted with prestressing. The roller body is divided into two parts 2, 3, carries two outer raceways for the rollers 4, 5 and has at its ends inner flanges 14, the bore 15 of which cooperates with the seals 13. The two parts 2, 3 are assembled by fitting two shouldered portions 16, 17. Application: in particular to rollers for crawler undercarriages.
