Abstract

Eine Dichtungsvorrichtung für Walzenlager weist Bewehrungs­ elemente (12 bis 15) auf. Im Betrieb einer derartigen Dich­ tungsvorrichtung hat es sich gezeigt, daß der Bereich (26) der Dichtungsvorrichtung bei hohen Umdrehungsgeschwindigkeiten zum Verbiegen neigt. Dabei wird die Ringrippe (18) und die Ringlippe (20) gegen die Dichtungsfläche (21) gepreßt. Die Fol­ gen davon sind hoher Verschleiß und frühzeitiger Ausfall. Es wird vorgeschlagen ein Bewehrungselement (24, 25) in den Be­ reich (26) des Dichtungskörpers einzuvulkanisieren. A sealing device for roller bearings has reinforcement elements (12 to 15). In the operation of such a you tion device, it has been shown that the area (26) of the Sealing device at high speeds of rotation tends to bend. The ring rib (18) and the Ring lip (20) pressed against the sealing surface (21). The fol This includes high wear and early failure. It is proposed a reinforcement element (24, 25) in the loading vulcanize rich (26) of the sealing body.
