  • Patent number: 10974596
    Abstract: A gearbox operating system shifts between 2-wheel and 4-wheel drive. The system includes a reversible motor, and a reduction gear train that is configured to be driven by the motor to move a plunger between extended and retracted plunger positions that shifts gears. A printed circuit board has at least two Hall effect sensing circuits. A magnet is carried by the reduction gear train and is rotationally movable relative to the Hall effect sensing circuits. A first Hall effect sensing circuits provides a first output signal indicative of the extended plunger position. A second Hall effect sensing circuits provides a second output signal that is indicative of the retracted plunger position. A controller monitors the two Hall effect sensing circuits to determine if a desired plunger position has been achieved and trigger an error code if the desired plunger position has not been achieved within a predetermined response time.

  • Patent number: 7533589
    Abstract: Provided is a motion converter which comprises a housing, a cam plate reciprocal to the housing, a lower link and an upper link. The cam plate has a groove which extends diagonally across the width thereof. The lower link is pivotably mounted to the housing and has a cam pin and a slot formed at a free end thereof. The cam pin is engageable to the groove of the cam plate. The upper link is also pivotably mounted to the housing in offset relationship to the lower link. A free end of the upper link has a link pin which is engageable to the slot. The motion converter is configured such that the lower link pivots in response to slidable movement of a cam pin within the groove during reciprocation of the cam plate. The upper link is configured to pivot in response to the slidable movement of the link pin within the slot during pivoting in a lower link.

  • Publication number: 20090100948
    Abstract: A rectilinear-motion actuator includes a motor, a reduction gear mechanism coupled with a motor shaft of the motor, and a rectilinear, reciprocative motion mechanism for converting a rotary motion of a last-stage gear of the reduction gear mechanism to a rectilinear, reciprocative motion. The last-stage gear has a pin provided thereon which is offset from its center of rotation. The rectilinear, reciprocative motion mechanism includes a movable plate having a slit and allowing the pin to move within the slit. The slit is arranged orthogonally to the axis of the motor shaft. The longitudinal center of the slit is located on a line in parallel with the motor shaft axis and passing through the center of the last-stage gear. The axis of reciprocative motion of the movable plate is offset from the line passing through the center of the last-stage gear in a direction away from the motor shaft.

  • Patent number: 7475584
    Abstract: A servo drive system of a press machine has a pair of servo motors which can generate necessary ram pressure by compositing and using a torque based on the same speed-torque characteristics. The servo motors are symmetric with each other in a mirror image manner. The servo motors are opposed to each other at opposite ends of an operation shaft which vertically moves a ram. The servo motors are integrally operated, thereby directly driving the operation shaft.

  • Patent number: 7363713
    Abstract: It is an object of the present invention to provide a useful technique for effectively reducing vibration in a reciprocating power tool with a simple structure. According to the present invention, a representative reciprocating power tool includes a motor, a tool bit, a slider, a motion converting mechanism and a counter weight. The tool bit performs a predetermined operation by reciprocating. The slider reciprocates to drive the tool bit. The motion converting mechanism converts a rotating output of the motor into a reciprocating movement of the slider. The counter weight is provided in the motion converting mechanism. Further, the counter weight reciprocates in a direction opposite to the reciprocating direction of the slider.

  • Publication number: 20070251341
    Abstract: Relates to a carrier (1) for positioning objects (5), which are oriented essentially vertically in the Z direction of a coordinate system, in relation to laboratory articles. These objects (5) are each individually received on a Z rod (12) and each of these Z rods (12) is oriented essentially identically as these objects (5) and is situated so it is movable along an axis running essentially horizontally in the Y direction of this coordinate system. These Z rods (12) are implemented as movable essentially vertically, in that they have teeth (16) which are engaged with a drive wheel (17), driven by a motor, of a Z drive of the carrier (1) comprising at least one profiled rod (18), which is situated essentially horizontally and in the Y direction. All Z rods (12) comprise a Z guide (43), situated on a cage (10) carrying the individual drive wheel (17), on which the Z rod (12) is guided in the Z direction by sliding.

  • Patent number: 7251896
    Abstract: The clipper has a cylindrical housing including a handle containing a battery and motor and a head pivotally mounted on the handle. The head carries a stationary blade and a reciprocating blade. Motion is transmitted from the motor to the reciprocating blade through a flexible rod. One end of the rod is connected to a protrusion offset from the axis of a gear connected to the output shaft on the motor. The other end of the arm carries the reciprocating blade. A control button is provided on the head. The control button can be manipulated to disengage the handle, to permit the head to be pivoted relative to the handle.

  • Patent number: 6899260
    Abstract: The nailing gun uses a motor as a power drive to rotate a drive gear wheel and a driven gear wheel, causing the drive gear wheel and the driven gear wheel to alternatively move a slider from a nailing position to a standby position, for enabling a nail driving tip, which is fastened to the slider, to be moved with the slider from the standby position to the ailing position by spring member, which is compressed to preserve energy when the slider moved from the nailing position to the standby position.

  • Publication number: 20040237678
    Abstract: A reciprocating shaft assembly in a reciprocating saw moves in a reciprocal motion and drives a saw blade via a blade holder. At least one bore is formed in an end of the reciprocating shaft assembly opposite the blade holder. A pin fixed to the saw passes through the bore and acts as a bearing to support the reciprocating shaft assembly in its reciprocating motion.

  • Publication number: 20030183026
    Abstract: An apparatus for achieving a transfer between rotary and reciprocating motion includes a supporting framework, and a crankshaft mounted for rotation within a fixed bearing on the framework. A circular, fixed sun element is centered on the axis of the crankshaft. A circular planetary element is mounted for rotation on the free end of the crank arm with a connecting rod rigidly connected between the planetary element and a wrist pin that is rotably connected to a piston rod which is in turn supported for rectilinear reciprocation. A drive means e.g., a chain, belt, gear or mechanical coupling is operatively connected between the sun element and the planetary element for rotating the connecting rod in the opposite direction from the crankshaft to thereby impart back and forth motion to the piston rod as the planetary element revolves in one direction and rotates in the opposite direction.
