Abstract
A power operated rotary knife (100) and method of operation includes an annular rotary blade (380). The knife further comprises a head assembly (300) extending from a handle assembly (200), the head assembly for rotatably supporting the annular rotary blade. The knife also includes a drive mechanism (600) disposed within the head assembly comprising a pinion gear (604) and a pinion shaft (970) rotatably disposed within a bushing (610), the drive mechanism being operatively coupled to the annular rotary blade, rotating the annular blade during use. A movable lubrication assembly (900) supported along a frame body between the handle assembly and the annular rotary blade, the rotatable lubrication assembly being rotatably disposed about a longitudinal axis of the handle assembly and providing a lubrication path (1000) extending from a lubrication adapter (924) to the pinion gear (604).
