The gear element has a release position and a brake position in which the gear element enters into frictional contact with the brake disk, generating a braking torque resisting winding off the flexible elongated member. Friction means is provided between the shaft and the gear element for generating a frictional resistance therebetween such that, if a driving force acting on the gear element does not overcome the frictional resistance established by the friction means, the gear element drives the shaft through friction means. However, if the driving force between the shaft and the gear element overcomes the frictional resistance, relative movement between the gear element and the shaft occurs.

  • Publication number: 20140061558
    Abstract: A level winding drum winch has a frame within which a rotatable drum is mounted. The frame is supported upon a pair of tracks upon which the frame may be slid from side to side. A motor connected to the drum rotates the drum for winding or paying out a cable wrapped around the drum. A feed screw attached within the frame is actuated by the motor to slide the frame from side to side as the cable is wound upon the drum. Thus, the cable is continuously directed at a substantially perpendicular angle, without bending or kinking, towards or away from the drum thereby forming a level winding and avoiding damage to the cable. The winch is particularly useful in handling relatively fragile composite cables useful for simultaneously towing and electronically communicating data with the objects towed by a boat.

  • Patent number: 8201810
    Abstract: A cable-wound drum style hoist with a rotating shaft supported by bearings that has both: (i) some freedom of motion in (at least) one of the bearings; and (ii) a pillow block in the shaft to impart some freedom of motion (beyond freedom to rotate about the central axis) in the shaft itself. By allowing some freedom of motion both the bearing(s) and the shaft, the hoist can better accommodate for bent shafts and/or slight misalignment of coaxial bearings. Also, a set of preferred connection hardware for mechanically connecting a hoist reducer box to a hoist backbone with preferred degrees of freedom/constraint.

  • Patent number: 8066261
    Abstract: A power or manually operated winch mechanism for handling the running rigging lines of a sailing yacht. The winch includes a winding drum, which winds and stores the line during line retrieving operations and controllably releases the line when desired. The new winch, while intended to be driven by on-board electric or hydraulic power, includes a novel mechanism, actuated by a conventional winch handle, for converting the winch to a multi-speed manual operating mode in the event of failure of the on-board power system. A clutch mechanism enables controlled release of line from the winding drum during manual operation, and enables adjustments and emergency release operation when operating in a power mode. Novel level wind features enable the lines to be appropriately tensioned during retrieval, and positively drawn from the drum when the line is not under load. Significant improvement in the safety and convenience of the crew is enabled.

  • Publication number: 20110272653
    Abstract: This invention relates to a portable winch assembly (10; 210) comprising a footplate (12; 212), a support frame (14; 214) which is locatable upon the footplate, a magazine (16; 216) which is locatable upon the support frame, and a drive mechanism (22; 222) which is connectable to the magazine to drive the magazine to rotate. The foot plate, support frame, magazine and drive mechanism comprise separable components which may be transported separately to a site of use and assembled into the winch at the site of use. The invention can provide a portable winch assembly capable of generating a tensile force of up to 10 tonnes, and is therefore suitable for pipe pulling and pipe bursting applications for example, and yet is made up of parts which can readily be carried to the site of use, which site of use may be inaccessible for vehicles.

  • Publication number: 20110180770
    Abstract: A winch includes a rotatable drum. A cable is wound onto the drum in one rotative direction and off the drum in a second rotative direction. A sealed axial flux permanent magnet drive motor includes a drive shaft selectively rotated by the motor in either direction of rotation. A gear train interconnects the drive shaft and the drum for rotatably driving the drum at a reduced rotative speed relative to the motor shaft. The motor can apply regenerative braking. A spring-applied electric release brake is connected to the drive shaft to apply a braking force to prevent rotation of the drum. A connecting shaft connects the gear train to the rotatable drum. The connecting shaft includes axially spaced splines that reduce the disparity in the gear train and drum centerlines to thereby reduce gyration therebetween. The drum can be made partially from carbon fiber to reduce the weight thereof.
