With Brake Means For Gearing Patents (Class 74/411.5)
  • Patent number: 9797491
    Abstract: An electric actuator assembly comprises a main actuator including a gear set containing a stepped friction portion located on a gear shaft of a drive gear thereof, an extension rod, and a power drive for rotating the gear set to move the extension rod through a lead screw, and a one-way bearing consisting of an inner race fitted to the gear shaft of the drive gear, an outer race surrounding the inner race, and a backstop mechanism mounted in between. When operating the power drive to rotate the gear set in lifting the extension rod, the inner race is rotated by the gear set relative to the outer race in one direction. When the driving power is off, the one-way bearing cannot rotate in reverse direction, the stepped friction portion is abutted against the flat contact surface of the inner race to produce a braking effect, preventing falling of the load that is supported on the main actuator.

  • Patent number: 9702369
    Abstract: An electric fan includes a fan body having a fan shaft coupled to a fan motor. A fan motor bracket is connected to a fixing portion of the fan motor. A swivel shaft is coupled to the fan motor bracket. A sleeve is mounted around the swivel shaft and is coupled to an output shaft of a swivel motor. The sleeve includes an inner periphery having grooves. The swivel shaft receives an elastic element extending in a radial direction of the swivel shaft. A ball is mounted to an end of the elastic element. The ball is biased by the elastic element to be partially received in one of the grooves. If the fan body is impeded during the swiveling movement, the ball moves inward and compress the elastic element, disengaging the swivel shaft from the sleeve to reduce damage to the sleeve and the output shaft of the motor.

  • Patent number: 9565945
    Abstract: A seating device can include a height adjustment mechanism that permits a height of a seat to be adjusted. The height adjustment device can be configured so that a user may provide a force to provide upward height adjustment and may also provide a force to allowing for a controlled downward height adjustment of the seat. The height adjustment device can include an actuator that is connected to a rotatable member via linkages. An end of one of the linkages may engage the rotatable member to prevent rotation of the rotatable member, which can prevent height adjustment of the seat. Movement of the actuator may cause the linkages to move so that the rotatable member is free to rotate so that a user may provide a force on the seat to effect height adjustment of the seat and/or cause the seat to be lowered at a desired speed.

The driving gear includes a pawl pivoted on a first surface and an elastic member disposed in a slot of the driving gear. The driven gear includes a ratchet disposed on a second surface facing the first surface. When the driving gear rotates with a driving speed along a driving direction, a centrifugal force is generated to drive the pawl moving to a clutching position to be engaged with the ratchet and drives the driven gear rotating with the driving gear. When the driving gear rotates with a nominal speed slower than the driving speed along a direction opposite to the driving direction, the engagement between the pawl and the ratchet is released, and the pawl is back to a nominal position so the driven gear does not rotate with the driving gear.

  • Patent number: 8718882
    Abstract: A method of controlling a transmission brake that is actuated by inlet and outlet valves. For determining when to transmit a disengagement signal for opening the outlet valve, the current input and output speeds are determined and the respective gradients of these speeds are calculated. Variation of the input speed, during the disengagement of the brake, is determined as a function of the input gradient, the optimum time for reaching the synchronous speed, during brake disengagement, is determined from the input speed variation as a function of the output gradient, and the time interval until transmission of the disengagement signal is determined as a function of the current input and output speeds and their gradients, by a back-calculation from the time when the synchronous speed is reached, taking a disengagement dead time of the brake, between transmitting the disengagement signal and start of disengagement, into account.

    Abstract: Sloped-for-rain urban sidewalks are horrible for wheelchair users because of the constant veering-off threat caused by gravity. Anybody who tries to self-propel a wheelchair on a city sidewalk for the first time is in for a rude awakening—the user must use one hand to steer by retarding one wheel, and that makes propelling inefficient, difficult and frustrating, to say nothing of the dangerous veering-off threat. Applicant's solution is to provide joining means to couple and uncouple the drive wheels. The joining means, when coupled, causes the two drive wheels to rotate in unison preventing the wheelchair from veering-off so that it travels straight when traversing a sloped surface, and when uncoupled allowing the two drive wheels to rotate at different speeds to allow turning. Joining means comprises: slip-clutch, gear configuration or the like, and may be automatic or user controlled.

    Abstract: The present invention pertains generally to a self-locking gear that includes an input shaft, a collar, a locking mechanism, and an output member. The collar is positioned eccentrically about the input shaft, and the locking mechanism prevents the collar from rotating. As a result, rotation of the input shaft causes the collar to gyrate about the input shaft, and the gyrating collar engages with the output member to turn the output member in the same direction as the input shaft. Torque applied to the output member with cause the output member to attempt to rotate the collar. However, the locking mechanism prevents the collar from rotating, thus locking the output member from rotation.

    Abstract: In a reclining device, a pawl is guided by guide walls formed in a guide while both of side portions thereof are applied thereto, so as to be movable only radially inwards and outwards. The pawl is divided into two divisional pawls configured to obliquely contact with each other, so as to be pressed and moved away from each other in opposite lateral directions and to be pressed against the guide walls positioned in respective lateral directions when the pawl is pressed and moved in the advancing direction by the pressing cam. A division line is set to form inclined surfaces that are configured to bring the two divisional pawls into face contact with each other obliquely with respect to the advancing moving direction of the pawl, and vertical surfaces that are configured to bring the two divisional pawls into face contact with each other in a direction perpendicular to the pawl advancing moving direction.

  • Publication number: 20120234121
    Abstract: An improved final drive is disclosed. The axle includes a double reduction gearbox for off-road machines, which, unlike currently available double reduction gearboxes, contains no planetary gear sets. The improved drive axle contains spur gears having pockets adapted to contain brake disc packs. The pockets may permit utilization of a plurality of brake packs within the gearbox without requiring additional space or enlargement of the gearbox housing. Use of spur gears may thus enable use of fewer gear parts, while use of multiple brake packs may enhance final drive brake capacity, improve longevity of the brake packs, and lengthen brake servicing cycles.
