Patent number: 8388229Abstract: A bearing arrangement (9) for a tine carrier (5) on a reel (1) of a harvester has first and second bearing elements and an attachment mechanism. The first bearing element is in the form of a bearing bushing (10) with a bearing bore (16) to rotatably support a tine carrier (5) around a rotational axis D. The attachment mechanism (17) attaches the bearing bushing (10) onto a support element (7) of the reel (1). The second bearing element is in the form of a bearing ring (25). The bearing ring (25) is fixable onto the tine carrier (5). The bearing ring (25) has a first ring portion (26) and a second ring portion (27). The ring portions (26, 27) are detachably connected to each other. The two bearing elements (10, 25) are rotatably held and axially supported relative to each other.Type: GrantFiled: October 21, 2009Date of Patent: March 5, 2013Assignee: Gebr. Schumacher Gerätebaugesellschaft mbHInventors: Frank Holler, Sascha Otto
