    摘要: A rotary cutter for a tunnel boring machine or similar machine has a cutter ring mounted to a hub. The hub is mounted on a shaft. A sleeve bearing system is positioned between the hub and the shaft for supporting the hub on the shaft and allowing relative rotation. A duo-cone seal assembly is positioned between the hub and the shaft to seal out contaminants from the sleeve bearing system. An oil gallery with lubricating oil for lubricating the sleeve bearing system is provided in the shaft.
