With Frictional Brake Assembly Mechanically Linked To, And Operationally Influenced By, Clutch Patents (Class 254/300)
  • Patent number: 9908757
    Abstract: A gas powered self-contained winch includes a combustion engine, a transmission assembly, a gear assembly and a clutch assembly connect to a spool capable of winding and unwinding a cable wire using forward and reverse drives. A hand controller communicates with the clutch assembly through a cable wire sufficient to control the winding and unwinding of the cable. Securing the winch for operation includes placing its center of gravity below the force line. A field changeable capstan option and remote control handle with throttle, power out lever, and kill switch are built in. A field installable hook float is provided for water rescue operations.

  • Patent number: 8807311
    Abstract: A winch clutch includes a driving block and a driven block respective connected to a motor and a transmission shaft of a deceleration clutch mechanism of a winch, the driving block and the driven block each having two spaced protruding flanges, a brake spring mounted between the driving block and the driven block and having retaining end portions disposed at two opposite ends thereof and respectively engaged into gaps between the protruding flanges of the driving block and gaps between the protruding flanges of the driven block, a brake bush accommodating the driving block, the driven block and the brake spring, and a one-way bearing fixedly mounted in the winch around the brake bush to limit rotation of the brake bush in a first direction. Thus, the winch brake has the characteristics of high reliability and high durability.

  • Patent number: 5324007
    Abstract: A load-hoisting system comprising a motor and gear box unit having the parallel outlet gears. Each outlet gear drives a hoisting device connected to the load by a cable, such a device comprising a toothed disk meshing with one of the two outlet gears, the toothed disk driving a winch drum via a friction clutch comprising an intermediate clutch disk, the cable being attached to and wound on the drum, the intermediate disk including retaining catches preventing it from rotating in a direction corresponding to lowering the load, the drum being fixed to a central shaft whose rotation in the direction corresponding to lowering the load ensures that the clutch is engaged. The central shaft is synchronized in rotation with the central shaft of the other hoisting device by means of a plate coupling and a coupling disk provided with tenons or grooves that are orthogonal, the two central shafts being supported by a fixed frame.

  • Patent number: 5249777
    Abstract: A portable winch includes a frame, a drum supported by the frame, and a motor for rotating the drum via a transmission. Each end portion of the drum extends into and is rotatably supported by respective annular bearing portions of the frame. Another portion of the frame extends into the drum from one end thereof substantially parallel to the longitudinal axis of the drum, supporting the motor and the transmission which are within the drum, an output shaft of the transmission being detachably connected to the drum at the other end thereof.
