  • Patent number: 11753888
    Abstract: A control unit includes a rotatable tubular body that rotates around a spindle. A torque transfer unit may be attached to the tubular body and the spindle. A force applied to the torque transfer unit by a biasing element may control a first torque applied by the tubular body to the spindle. The first torque is independent of a rotational velocity of the tubular body. A second torque is applied to the spindle with a torque generator, the second torque controlling the net torque. Controlling the net torque allows the absolute orientation of the control unit to be controlled.

  • Patent number: 6648106
    Abstract: To ensure durability of a one-way clutch, by reducing surface pressures applied to side bearings, a one-way clutch has end bearings that are disposed between an outer race and an inner race and that maintain concentricity between the races. In a supporting structure wherein one of the outer race and the inner race is fitted to a stationary member and the other race is fitted to a rotational member, a clearance of a fitting portion between the stationary member and one of the races is narrower than a clearance between the rotational member and the other race. A load resulting from whirling of the rotational member is absorbed by the greater clearance, and a high load resulting from radial movements of the race fitted to the stationary member and a weight of the race is supported by the stationary member. Thus, loads applied to the end bearings are reduced.

A gear damper is mounted to the frame and is operably engaged with the main gear to dampen rotational movement of the main gear. The damper can be configured for one-way and two-way damping.

  • Patent number: 6488130
    Abstract: An apparatus for the application of a braking force to a wheel of a wheelbarrow, hand cart or other type of a cargo portage device includes a twist grip mechanism with a latching type of a ratchet attached to the handlebar of the device. As the twist grip mechanism is rotated a progressive braking force is applied to the wheel by tightening a brake band that extends around a drum that is attached to the wheel. A cable is attached at one end to the twist grip mechanism and to the brake band at its remaining end. The ratchet maintains the braking force that is applied until a thumb release lever is depressed which disengages a ratchet dog from contact with any of a plurality of ratchet teeth.

  • Publication number: 20020175029
    Abstract: A relatively simple hydraulically operated disc brake mechanism for drive systems which store torsion by reason of being under torque is disclosed. Certain drive systems such as the drive strings for deep well submersible pumps store considerable torsion due to torque and elasticity. Such torsion must be controllably released if drive power is interrupted. The disc brake mechanism includes a housing that defines a reservoir for lubricating oil for the bearings of a shaft that drives a bi-directional hydraulic pump. When the shaft turns in an operating direction, the pump conveys the lubricating oil in a closed circuit by way of a control manifold through the brake mechanism and back to the reservoir, without activating the brake mechanism. This flushes the complete lubricating oil circuit including the control manifold and the brake mechanism to prevent accumulation of gas pockets therein at locations of little or no fluid flow.

  • Publication number: 20020096405
    Abstract: A damping device (14) for movable furniture parts comprising a fluid damper which is in the form of a rotational damper (20) and which includes two members which are rotatably movable relative to each other, namely a housing and a drum disposed in the housing. A damping fluid, for example a silicone oil, is disposed in the housing. During the damping action one of the two members is rotated by an actuating member and the other member is held fast. The rotational damper (20) is radially displaceably mounted and during the damping action is pressed by the actuating member against a retaining element (17).

  • Publication number: 20020011385
    Abstract: To ensure durability of a one-way clutch, by reducing surface pressures applied to side bearings, a one-way clutch has end bearings that are disposed between an outer race and an inner race and that maintain concentricity between the races. In a supporting structure wherein one of the outer race and the inner race is fitted to a stationary member and the other race is fitted to a rotational member, a clearance of a fitting portion between the stationary member and one of the races is narrower than a clearance between the rotational member and the other race. A load resulting from whirling of the rotational member is absorbed by the greater clearance, and a high load resulting from radial movements of the race fitted to the stationary member and a weight of the race is supported by the stationary member. Thus, loads applied to the end bearings are reduced.

  • Patent number: 6189660
    Abstract: A ratchet wheel device for a baby walker provided on the bottom surface of a chassis of the baby walker, it is comprised of a wheel rim, two transmitting gears, a transmitting member and a cover. The wheel rim is provided therein with a receiving chamber. The two transmitting gears are mounted on both sides of the receiving chamber and can fitly move therein and can be stopped by two stop portions in the receiving chamber. The transmitting member is provided in the receiving chamber and fixed on the chassis of the baby walker. A plurality of engaging teeth are provided thereon to engage with the transmitting gears. When the wheel rim is rotated to a specified direction, the two transmitting gears will not interact with the stop portions. While when it is rotated in the contrary direction, the two transmitting gears will be engaged by the transmitting member to be stopped by the stop portions and to limit rotation of the wheel rim.
