    摘要： The disclosure relates to a shaft adjuster, in particular a camshaft adjuster, comprising a drive gear having a spur gear toothing and a clamping gear which is arranged coaxially relative to the drive gear and which is loaded by a spring acting in the circumferential direction. The spring is also designed as an axial securing element for axially securing the clamping gear on the drive gear.

    摘要： Systems and method for a cam phaser are provided. In some configurations, the cam phaser includes a drive member having a first mating surface, a driven member having a second mating surface, and a locking mechanism arranged between the first mating surface and the second mating surface. The locking mechanism is operable to contact the first mating surface and the second mating surface, in response to an outside force applied to the driven member that loads the locking mechanism. The cam phaser further includes an engaging member. The engaging member is configured to selectively actuate the locking mechanism to enable rotation of the driven member relative to the drive member. The cam phaser may include a reaction mechanism configured to receive additional force from an input mechanism and selectively transmit the additional force to the driven member to unload the locking mechanism.

    摘要： The valve timing control unit includes a valve timing control mechanism that includes a driving rotary body, a driven rotary body, an electric motor and a deceleration gear each for setting the relative rotational phase of the driving rotary body and the driven rotary body, and a phase sensor unit that detects the actual phase of the driving rotary body and the driven rotary body. The valve timing control unit includes a controller that controls the electric motor to reduce a phase difference between the actual phase and a target phase, and the controller includes a swing controller that swings the target phase in vicinity of the target phase when the target phase is maintained and the actual phase having a fluctuation amount is held in a holding region, in which the fluctuation amount is less than a preset value.

    摘要： An electrically-actuated variable camshaft timing (VCT) phaser is employed for use with an internal combustion engine (ICE). The electrically-actuated VCT phaser includes a gear set assembly and a fixture. The gear set assembly has an input gear and an output gear, among other possible components. The input gear receives rotational drive input from an engine crankshaft, and the output gear transmits rotational drive output to an engine camshaft. The fixture is secured in the gear set assembly. Amid installation of the electrically-actuated VCT phaser on the ICE, the fixture constrains rotational movement of the gear set assembly. After installation, the fixture can be removed from the gear set assembly.

    摘要： An engine variable camshaft timing (VCT) phaser assembly is equipped in an internal combustion engine (ICE) to adjust the rotation of the engine's camshaft relative to the engine's crankshaft. The adjustments advance and retard the opening and closing movements of the engine's intake and exhaust valves. An electric motor and a planetary gear set work together amid use of the VCT phaser assembly. The planetary gear set can include two or more ring gears, planet gears, and a sun gear. A backlash condition sometimes experienced in previous VCTs is minimized in the VCT phaser assembly by one or more springs that urge the planet gears into engagement with the ring gears.

    摘要： A harmonic drive (1), including a wave generator (8), a flexible, externally toothed gear component (14), in particular in the form of a flex ring, which can be deformed by said wave generator, and at least one internally toothed gear component (4, 5) that meshes with the flexible, externally toothed gear component (14). The flexible, externally toothed gear component (14) has a non-circular basic shape in relation to its mechanically non-loaded state.
