摘要： The present invention relates to a fastening arrangement of a drive wheel member (DW) for an endless track (E) of a tracked vehicle (V). Said drive wheel member (DW) comprises a hub member (H) and a drive sprocket member (S1, S2), said drive sprocket member comprising a set of tooth members (10) arranged around the circumference of said drive sprocket member (S1, S2). Said drive sprocket member (S1, S2) further comprises a ring-shaped support member (20) for tooth members (10) of said drive sprocket member. Said fastening arrangement is configured for fastening a tooth member (10) of the set of tooth members (10) to the support member (20) so that said tooth member (10) is in an operation position for engaging with said endless track, said fastening arrangement comprising an attachment device configured to detachably attach said tooth member (10) to said support member (20) such that said tooth member is detached from the operation position if said tooth member is subjected to a radial force (F) exceeding a certain threshold. The present invention also relates a tracked vehicle.

摘要： A shaft assembly has a shaft and a journal bearing that is fixedly coupled to the shaft so that rotation of the shaft causes corresponding rotation of the journal bearing. A bearing race has an inner surface that defines a cylindrical bore and a lubrication groove that extends radially outward from the cylindrical bore. The journal bearing is rotatably disposed within the cylindrical bore of the bearing race.
