Abstract: The disclosure relates to an adjustment gearing device for a shaft, comprising a strain wave gearing. The strain wave gearing has a spur gear device and an inner rotor, and the spur gear device has a first cylindrical section and a collar section. The first cylindrical section has a first diameter, and an outer toothing, and the inner rotor has an inner toothing, said outer toothing and inner toothing meshing together at least in some regions. The adjustment gearing device also comprises an outer rotor, said inner rotor being rotatable in a rotational direction relative to the outer rotor. The spur gear device is rotationally fixed to the outer rotor, and has a second cylindrical section for contacting the outer rotor. The second cylindrical section has a second diameter, and the second diameter is larger than the first diameter.

Abstract: A valve timing controller includes: a driving side rotation member that rotates synchronously with a crankshaft of an internal combustion engine; a driven side rotation member that integrally rotates with a cam shaft of the internal combustion engine; a phase regulating mechanism with which a relative rotation phase of the driving and driven side rotation members around a rotation axis is set by a driving force of an electric motor; a phase sensing portion that acquires the relative rotation phase; and a phase controlling section that controls the electric motor to set the relative rotation phase based on an acquisition result by the phase sensing portion. The phase sensing portion includes a cam angle sensor, a reference determination sensor, and a pattern storage unit. The valve timing controller further includes a phase acquisition portion.

Abstract: A driving rotor is configured to rotate about a rotational shaft center in conjunction with a crankshaft. A driven rotor is configured to rotate about the rotational shaft center in conjunction with the camshaft. A deceleration mechanism is configured to change a relative rotational phase between the driving rotor and the driven rotor by using a driving force of an electric motor. The deceleration mechanism includes an internal gear portion, which includes an internal tooth extending radially inward, and an external gear portion, which includes an external tooth extending radially outward and engaging with the internal tooth. A linear expansion coefficient of the external gear portion is greater than a linear expansion coefficient of the internal gear portion.

Abstract: The relates to an electromechanical camshaft adjuster comprising an electric motor and an adjusting gear, which has a housing two housing parts, that are sealed off with respect to each other by means of a static seal and with respect to the electric motor and a cylinder head by means of two dynamic seals. A first housing part of the adjusting gear a pot shape that tapers in a stepped manner towards a housing bottom of the housing part, said pot shape having three different inner diameter regions. In the region closest to the bottom with the smallest inner diameter, a stop plate that acts in the circumferential direction is held. In the region with the middle inner diameter, an output ring gear is mounted with play, and in the region with the largest inner diameter, an input ring gear is secured.
