Abstract: A bevel gear drive with two bevel gears rotates about respective rotation axes intersecting at an intersection point, forming an angle of intersection. A computer determines the tooth shape of these tooth flanks based on data other than a tooth shape. The data are characteristic for a particular contact path represented by a sequence of contact points. The tooth shape of the tooth flanks is determined for several contact paths, with the interacting tooth flanks at all contact points having a common normal, which passes through a pitch point located between the two rotation axes and spaced from the intersection point equal to the radius r. Geometry data for the bevel gear are determined from the shape of the tooth flanks and stored in a format suitable for automatically generating a parts program for a processing machine with at least five axes.

Abstract: A compliant gear assembly for a gear train of an internal combustion engine includes a hub subassembly having a first hub component and a second hub component. The first hub component defines a first axis, and the compliant gear assembly includes a gear ring rotatable relative to the hub subassembly and defining a gear ring axis of rotation. The second hub component is movable relative to the first hub component between a first stop position and a second stop position. A compliance mechanism is coupled between the first hub component and the second hub component and biases the second hub component toward the first stop position. Translating the second hub component relative to the first hub component in a direction normal to the first axis attenuates torque spikes induced for example via fuel injector actuation and/or cylinder firing in an engine gear train employing the compliant gear assembly.

Abstract: An automatic transmission has a park system with a shaft and a parking pawl. The shaft rotates in response to a gear shift lever, and a detent lever positions the parking pawl in response to rotation of the shaft. A detent spring assembly biases the detent lever and has a detent spring, cage, and roller assembly. The cage aligns the roller assembly, while the detent spring is connected to the cage at one end and has a flat reaction surface formed at a second end. A cage notch portion aligns the cage with the detent lever, and the roller assembly into a perpendicular orientation with detent lever teeth. The notch portion engages either a detent tooth or a stationary portion of an internal mode switch (IMS). A shaft inserts into a roller through a side hole in the cage to retain the roller assembly therewithin.

Abstract: The invention relates to a skew gear constructed as a built skew gear and provided with attenuation. The skew gear wheel has a first flange for rotation-locked arrangement of the skew gear on a shaft or a pinion, a second flange or a disk, and a ring gear arranged and rotatable therebetween. The two flanges, or the first flange and the disk, are frictionally or positively connected with one another, wherein their respective elements providing the connection extend through the ring gear in the axial direction. According to the invention, at least one elastomeric element is overmolded on an inside contour of the ring gear for forming the attenuation, so that the ring gear and the attenuation form a single unit.
