  • Publication number: 20140216185
    Abstract: Device and method for enabling independent tuning of frequency and amplitude of a reverse crankshaft motor. The reverse crankshaft motor provides periodic reciprocating motion based on periodic rotational motion from a rotational motor. The reverse crankshaft motor includes a crankshaft structure having first and second frames with a third axle arranged between them and connected to them by hinges. An amplituder is affixed to the third axle and may communicate with an external device. As the first and second frames move toward or apart from each other, the third axle moves radially toward or away from a central axis of the crankshaft structure. The position of the third axle determines the amplitude of the periodic reciprocating motion of the amplituder. By adjusting the position of the first and second frames, the operator may adjust the amplitude independently from the frequency of the periodic rotational motion supplied by the rotational motor.

The second auxiliary gear meshes with a central gear. The central gear is an internal gear, which has a center line that coincides with the crankshaft axis.

    Abstract: Reciprocating motion can be converted to rotary motion through a crankshaft and a connecting rod. In a joint between a connecting rod and a piston, the connecting rod rocks with respect to the piston. In some situations, the connecting rod is a pullrod always in tension or a pushrod always in compression making it difficult to lubricate the bearing surfaces. A joint is disclosed in which the bearing surfaces rock with respect to each other with no sliding between the surfaces. The connecting rod has a bearing surface that is part of a cylinder having a radius equal to a distance between a central axis of the journal to which the connecting rod is coupled and the bearing surface. The pin has a convexly- or concavely-curved bearing surface and the local radius is based on material properties and the local peak force that the rocking joint is designed to transmit.

    Abstract: An adjusting mechanism for desired angle of an oscillating electric fan is disclosed. The adjusting knob is conveniently located about the top rear portion of the fan motor, adjacent the clutch knob. Adjusting the oscillating angle may be made when the fan is at rest, when it is running and oscillating at the same time, or when it is running at a fixed direction. Adjusting is fast and simple, only one hand is needed and no tools and mechanical know-how is necessary.

  • Patent number: 7798028
    Abstract: A transmission system made of gears and bearings. The system improves the efficiency of force transfer between rotational motion and rectilinear motion. To accomplish this, the gears and bearings are assembled to allow maximum torque output during force input and reproduced cyclically. Bearings of the transmission system allow a crank to rotate to a position to increase the torque applied on gears to output shaft.

  • Publication number: 20100137041
    Abstract: Disclosed is a pivot apparatus having a pivot member adapted so that, when pivoted to the service angle, it slides to the service position while interlocking with the pivot movement and is set in the service condition. To this end, a link interlocks the pivot movement based on the pivot structure with the sliding movement based on the siding structure. Particularly, the sliding structure is applied to the coupling between the support and sliding members, and the pivot structure is applied to the sliding and pivot members to pivotably couple them to each other. The link connects the support and sliding members so that, as the pivot member pivots relative to the sliding member by means of the user's pivot force, the sliding member slides to the desired direction and distance from the support member while interlocking with the pivot movement. As a result, the pivot member slides while interlocking with the pivot movement.

  • Patent number: 7685896
    Abstract: A reciprocating drive assembly is disclosed for use in a fluid mixer to impart reciprocating movement along a longitudinal axis to a shaft carrying a mixing head. The drive assembly includes a housing, a flywheel mounted for rotation about a rotational axis, a crank member projecting from the flywheel, and a yoke supported by the housing for movement along a yoke axis parallel to the longitudinal axis. The yoke is releasably connected to the shaft and has a linear race formed therein for receiving the crank member. Guide assemblies are connected to the housing and to the yoke for sliding engagement therewith along guide axes parallel to the yoke axis. The yoke is between the guide assemblies. The crank member is caused to translate linearly within the race, thereby urging the yoke to move along the yoke axis to effect longitudinal reciprocating movement of the mixing head.

    Abstract: A method for providing torque to assist in moving a component of a mobile platform. Biasing forces may be applied to opposing portions of a torque transferring member that enable the torque transferring member to be maintained in a position of equilibrium. A torque may be applied to one of the component and the torque transferring member such that the biasing forces cooperatively exert a torque on the torque transferring member to assist in moving the torque transferring member out from the position of equilibrium. Motion of the torque transferring member out from the position of equilibrium may be used to assist in moving the component.

  • Patent number: 7549361
    Abstract: A vibration damping device is described that dampens vibration produced during the conversion of rotational motion into reciprocal motion. The damping is performed using a simple structure wherein first and second conversion mechanisms are symmetrically arranged with respect to a plane of symmetry, first and second rotating shafts rotate opposite to each other at a constant speed, and the rotational motion is converted into reciprocal motion. The total of mass acting on gravity centers of a first balancer and a second balancer is approximately equal to the total of mass reciprocally driven by a first driving shaft and a second driving shaft. Both gravity centers are positioned 180 degrees to the first driving shaft and second driving shaft across the axes of the first rotating shaft and second rotating shaft. As a consequence, the forces in the direction of an axis can be balanced suppressing vibration.

  • Patent number: 7516680
    Abstract: An apparatus and method for providing a torque to an external member to assist in twisting or deforming the external member. In one implementation the apparatus is useful for providing a force to a torque tube to assist in rotating, bending or twisting a wing, an airfoil, or a rotorcraft blade. The apparatus includes at least one biasing member which provides a biasing force to a linkage assembly, where the linkage assembly is pivotally coupled to a torque tube. The torque tube is fixedly coupled to the structure which needs to be bent, twisted or flexed. The energy stored in the biasing member provides the great majority of mechanical force required to rotate the torque tube and bend, twist or deform the structure when the structure is urged back into an unflexed or un-deformed state, the energy stored in the structure is transferred back to the apparatus.

An adjustment ring (41) formed such that an outer circumference is eccentric with respect to an inner circumference is provided to the outer circumference of the rotary ring (34), and a slide (5) is mounted to the outer circumference of the adjustment ring (41). Since the slide (5) and a slide drive unit (30) are arranged to be superposed substantially at the same height, a distance between the slide drive unit (30) and a lower end of the slide (5) can be reduced and the entire height of a servo press (1) can be reduced. In addition, since the height position of the slide (5) can be finely adjusted by rotating the adjustment ring (41), a press working can be performed with high accuracy.
