  • Patent number: 10240648
    Abstract: An electromagnetic-released, multi-disc, enclosed safety brake for primary use in offshore marine winch applications includes a stationary coil housing that encompasses springs that apply pressure to an armature, a pair of separator plates, three friction plates and a stationary endplate. The multi-disc brake is released by means of a DC voltage applied to the brake coil. The excited coil generates an electromagnetic force that attracts the armature across an air-gap thus reducing the spring force applied to the disc pack. The brake is applied when the DC voltage is removed from the brake coil. Various structures and methodologies for reducing vibrations in the brake are also provided.

  • Patent number: 9228619
    Abstract: A friction clutch having a clutch ring and having two clutch disks, which are mounted so as to be rotatable about a clutch axis of rotation and on which friction surfaces are formed, is presented. In this case, the clutch ring and the clutch disks can be moved parallel to the clutch axis of rotation and relative to one another in such a way that, for torque transmission, first friction surfaces on each of the clutch disks can be moved into frictional surface contact with a respective second friction surface on the clutch ring. A first and a second friction surface in each case are matched to one another as a friction surface pair, having in each case a friction surface curved convexly in the direction of the clutch axis of rotation and a friction surface curved concavely in the direction of the clutch axis of rotation.

  • Patent number: 9175732
    Abstract: The present subject matter relates to clutch arm and release devices and methods such as for a variable speed transmission. A clutch linkage can include a control shaft pivotable about an axis, a substantially U-shaped arm connected at two points to the shaft, and a plurality of projections positioned on the arm. The arm can be moved between positions in response to rotational movement of the control shaft, and the projections can thereby engage and exert a force on a movable sleeve to move the sleeve, such as for causing a clutch bearing to move between an engaged and a disengaged position.

  • Patent number: 8196725
    Abstract: A device for connecting, in a rotationally fixed manner, a shaft to at least one component which is rotationally supported on the shaft, such as a gear wheel of a gear in a transmission. The device includes an actuating element that is rotationally fixed, but axially slides on the shaft, such that when the element is actuated by an actor, the element actively, frictionally communicates with the component to at least approximately equalize a rotational speed difference, between the component and the shaft. The actuating element can be actuated by the actor with a force to frictionally connect the component to the shaft in a rotationally fixed manner. The device further includes a holding device, which retains the actuating element in a shift condition essentially equivalent to the rotationally fixed condition of the component without further actuation of the actor.

  • Patent number: 7231845
    Abstract: A multi cone selector in a transmission employs sandwiched cone friction surfaces 19A, 20A and 21A and these are shown in free or unengaged state while the corresponding friction surfaces as numerals 19, 20 and 21 are shown as engaged. This comparative illustration shows the relative positions of the surfaces at different times since the “A” surfaces and the non “A” surfaces are the same circumferential surfaces. The cone selector is used to engage free rotating gear a female part 22 of a multi-cone selector. A hydraulic actuator 23 is received by internal gear case wall 24 formed so as to prevent any radial or axial movement of the actuator itself. A hydraulic coupling, in this case the hydraulic coupling is formed as hydraulic springs or bags illustrated at 26. The crown of hydraulic spring outlet piston is formed so as to clip in a housing of a thrust bearing 29.

  • Patent number: 7007881
    Abstract: A fishing reel has a spool with a spindle and the spindle has a retaining portion to be engaged and disengaged with a slot of a gear rod. The gear rod is provided with two cut faces. While the spool is rotating in high speed, the retaining portion is attached on the cut faces first, and then the retaining portion is totally engaged with the slot after the spool rotates continuously to a predetermined angle. As a result, the spool can be stopped successfully while the spool is rotating in high speed and no damage is occurred between the spindle and the gear rod.
