Gear Control System for Vibration Attenuation
A power take off unit includes an input gear, an output gear, and an intermediary gear that cooperate to transfer power from a rotational power source to an operating target. The power take off unit has a control module that biases the intermediary gear relative to the input gear and the output gear to reduce gear rattle vibrations associated with intermeshed tooth looseness.
GEAR UNIT FOR MOTOR VEHICLE
A gear unit for a motor vehicle including a rotatable worm gear shaft rotating about a rotation axis and cooperating with a worm gear wheel in an engagement region spaced from the rotation axis. A pivotable rotary bearing mounts the worm gear shaft on a housing on one side of the engagement region and a loose rotary bearing, pretensioned in the direction of the spacing axis, mounts the other side in the housing. A support device supports the pivotable rotary bearing on the housing in the direction of the rotation axis. To optimize engagement between a worm gear shaft and a worm gear wheel, the pivotable rotary bearing pivots relative to the housing about a pivot axis perpendicular to the rotation axis and to the spacing axis. A support point of the support device is offset relative to the rotation axis along the spacing axis towards the engagement region.
POWER TRANSMISSION DEVICE AND ENGAGEMENT ADJUSTING DEVICE FOR GEAR MECHANISM
A power transmission device according to one aspect of the disclosure includes a first gear, a base member, a second gear, a support block, a position adjusting unit, and a fixing unit. The base member rotatably supports the first gear. The second gear engages with the first gear so as to be able to transmit power. The support block rotatably supports the second gear. The position adjusting unit adjusts relative positions of the support block and the base member in a direction in which an engagement depth between the second gear and the first gear varies. The fixing unit fixes the relative positions of the support block and the base member.
Sealing plug for a reducer casing, bearing a meshing play-compensating carriage
A plug for closing an opening of a casing, the plug including a solid hub, with central axis, as well as a retaining member which ensures the axial attachment of the plug in the opening, the plug including a play-compensating carriage, which is distinct from the hub and which is movably mounted on a guiding support borne by the hub, the guiding support being arranged in such a way as to axially retain the carriage and to guide the relative movement of the carriage with respect to the hub in a direction termed the “play-compensating direction” transverse to the central axis, a spring-type resilient member, arranged between the guiding support and the carriage, and an orientating member arranged so as to orientate the plug, and consequently the play-compensating direction defined by the guiding support, in azimuth around the central axis, according to a predetermined orientation with respect to the casing.
ELECTRIC POWER STEERING SYSTEM REDUCER AND ELECTRIC POWER STEERING SYSTEM
Reducer device having electric power steering, including a support member, an endless screw, a toothed wheel that meshes with a helical spline arranged on the endless screw, the endless screw including a first end capable of being rotated, and a second end receiving a first rotation-guiding means and a second rotation-guiding means, respectively, causing the endless screw to pivot relative to the support member, the second rotation-guiding means including a damping sleeve and a rotation-guiding device, the sleeve surrounding the rotation-guiding device, the second rotation-guiding means including a centering means including a press-fitting part inserted into the rotation-guiding device, and an attachment part rigidly connected to the support member.
Gear reducer having a sealing plug providing axial support to a spring for gear slack compensation
The invention relates to a gear reducer (1) for an assisted-steering module, including a casing (3), a worm (4) which meshes with a worm wheel (6), and a spring (10) for taking up gear play, which presses said worm (4) radially against the worm wheel (6), the wall of the casing (3) being bored, away from of the axis (XX′) of the worm, with an opening (14) sealed by a plug (15), the spring (10) for taking up gear play including at least one retaining lug (17, 18) which projects radially to the axis (XX′) of the worm (4), and the hub (20) of the plug (15) having a guiding wall (21) that is substantially transverse to the axis (XX′) of the worm (4), which is designed to be placed axially opposite said at least one retaining lug (17, 18), in order to prevent the axial movement of the spring (10) beyond a predetermined functional travel.
Assembly for adjustably mounting a gear of a pump to a gear of a driver equipment
An assembly for adjustably mounting a gear of a pump to a gear of a driver equipment includes a shroud member, and a hollow elongated stub-shaft. The stub-shaft includes a flange, and a hub member axially extending from the flange. The shroud member defines a first aperture whose diameter is greater than a diameter of the hub member. The hub member is received within the shroud member via the first aperture. The flange has a first set of holes to receive a first set of fasteners and releasably couple with the body of the pump. The flange also has a second set of holes that are configured to receive a second set of fasteners and releasably couple with the shroud member. A diameter of the second set of holes is greater than a diameter of the second set of fasteners.

The power take off unit has a control module that biases the intermediary gear relative to the input gear and the output gear to reduce gear rattle vibrations associated with intermeshed tooth looseness.
GEAR MECHANISM, SPEED REDUCER AND DRIVE DEVICE USING SPEED REDUCER
An aspect of the present invention provides a speed reducer including a supporting block, an input gear rotatably supported on the supporting block, an intermediate gear meshing with the input gear, an output gear meshing with the intermediate gear, and a gear position changing mechanism configured to change a position of the intermediate gear relative to the input and output gears.
Steering gear
A steering gear includes a gear wheel, a screw pinion meshing therewith, and a screw pinion shaft that includes the screw pinion. The screw pinion shaft is mounted on one side of the screw pinion in a fixed bearing. The steering gear includes a rotary bearing which comprises an inner bearing shell and an outer bearing shell. The outer bearing shell is connected to an inner ring of a swivel ring. The inner ring is connected to an outer ring of the swivel ring by a torsion web so as to pivot about a pivot axis. The torsion web runs at a distance from a supporting surface. The distance is dimensioned such that the torsion web does not contact the supporting surface when the screw pinion shaft is not loaded with a torque, and partially contacts the same when the screw pinion shaft is loaded with an operating torque.
