摘要： A power operated knife comprises a blade supporting structure supporting an annular blade for rotation about a central axis. The blade and blade supporting structure are engagable along bearing contact locations that are spaced apart in a direction parallel to the axis so that the blade is stabilised both radially and axially as the knife operates. The blade supporting structure comprises a split blade housing member that is radially expandible and contractible to receive the blade. The split blade housing member and blade engage along relatively short lines of bearing contact that serve to minimize friction and blade heating when the knife operates. The bearing locations are spaced apart both circumferentially around the blade perimeter and in the direction of the axis so that the blade position is stabilized during operation of the knifes.

摘要： A blade housing assembly for a power operated rotary knife including a split blade housing and a cam mechanism for changing a blade housing diameter between blade supporting and blade changing positions. The split blade housing includes an annular blade support section, a mounting section and a split extending through the mounting section and an inner wall of the blade support section and defining a split distance between first and second circumferential ends of the inner wall. The split includes a radial split section and an angled split section adjacent the inner wall. The mounting section includes first and second body portions on opposite sides of the split. The cam mechanism includes a cam plate bridging the first and second body portions and a cam member rotatably supported by the cam plate. The cam member is rotatable between closed and open positions to change the blade housing diameter.

摘要： A power operated rotary knife (100) including: an annular rotary knife blade (300) including a knife blade bearing surface (319); a blade housing (400) defining a blade housing bearing surface (459); and a blade-blade housing bearing structure (500) disposed between the knife blade bearing surface (319) and the blade housing bearing surface (459). The blade-blade housing bearing structure (500) includes a rolling bearing strip (502) having a plurality of rolling bearings (506), such as ball bearings, disposed in spaced apart relation in a flexible separator cage (508). The rolling bearing strip (502) traverses through an annular passageway (504) defined between the knife blade bearing surface (319) and the blade housing bearing surface (459) to secure the knife blade (300) to the blade housing (400) and support the knife blade for rotation about a central axis (R) with respect to the blade housing (400).
