International Classification:

F16C 1/00

US Classification:

464052000

Abstract:

A flexible shaft drive transmission for a power driven tool. The transmission features a first end connectable to a drive motor and a second end connectable to the power driven tool. The transmission includes a flexible drive shaft assembly comprising a flexible elongated drive transmitting member, a first end of the drive transmitting member including a first coupling operatively coupled to the drive motor and a second end of the drive transmitting member including a second coupling operatively coupled to the power driven tool. The transmission further includes a tubular casing surrounding and coaxial with said drive shaft assembly and supporting said drive shaft assembly for rotation generally about a longitudinal axis of said drive shaft assembly relative to said casing. The casing includes a core comprising a spiral wound strip of material having interlocking opposing edges, a braided wire layer surrounding the core, and a polymer layer surrounding the braided wire layer.

Abstract:

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

US Classification:

464 7, 464 53, 464176

Abstract:

A flexible drive transmission comprising a flexible drive shaft assembly having a first end connectable to a drive motor and a second end connectable to a driven implement, a tubular casing surrounding and coaxial with the drive shaft assembly, a lubricant disposed within the casing, and a lubricant-seal for blocking leakage of lubricant from the second drive shaft assembly end. The drive shaft assembly comprises a flexible elongated drive transmitting member, a first drive coupling fixed to the drive transmitting member at a first end, and a second drive coupling fixed to the drive transmitting member at the second end. The casing rotatably supports the drive shaft assembly and comprises a tubular flexible conduit, and end fitting that permanently secures one drive coupling against axial movement relative to the casing. The lubricant seal is disposed between the second end fitting and the drive shaft assembly second end for blocking leakage of lubricant from the casing as the casing and drive shaft assembly rotate and shift axially relative to each other.
