ENSEMBLE MOYEU DE DISQUE DE BARRE DE COUPE ROTATIVE POUR DÉVIER LES DÉBRIS, ENSEMBLE DE BARRE DE COUPE ROTATIVE MODULAIRE LE COMPRENANT ET MACHINE DE TRAVAIL AYANT UN ENSEMBLE DE BARRE DE COUPE ROTATIVE MODULAIRE
A rotary cutterbar disk hub assembly (212) for diverting debris, a modular rotary cutterbar assembly (200) with such, and a work machine (100) with a modular rotary cutterbar assembly (200) is disclosed. The rotary cutterbar disk hub assembly (212), comprising: a cutterbar housing (202) defining an internal cavity (1144)； a bearing housing (1504) defining an axis (218) and coupled to the cutterbar housing (202), where a bearing (1506) is configured to be coupled to the bearing housing (1504)； a labyrinth (1602) defined in the bearing housing (1504) circumferentially about the axis (218)； a barrier (1612) formed by the bearing housing (1504) at a location radially outward of the labyrinth (1602)； a disk hub (1502) positioned concentric with the axis (218) and coupled to the bearing housing (1504) and cutterbar housing (202), the disk hub (1502) forming at least one protrusion (1610) that extends towards the bearing housing (1504) and is radially adjacent to the labyrinth (1602)； wherein, the barrier (1612) restricts a portion of the debris from entering the labyrinth (1602), and the at least one protrusion (1610) severs debris that is disposed near the labyrinth (1602) as the disk hub (1502) rotates. A modular rotary cutterbar assembly (200) for diverting debris during a mowing operation, comprises a modular cutterbar (1000) having an internal cavity (1144) defined therein, the modular cutterbar (1000) comprising a plurality of cutterbar modules (1002) coupled to one another along a cutterbar axis (204) wherein each cutterbar module (1002) comprising a rotary cutterbar disk hub assembly (212). Further, a work machine (100) having a frame (112)； comprising at least one ground engaging mechanism coupled to the frame 112 and adapted to provide movement to the work machine (100)； a prime mover coupled to the frame (112) and adapted to selectively provide power to the work machine (100) and a modular rotary cutterbar assembly (200).
