摘要： A transmission mechanism has a set of two composite sprockets, each having pinion sprockets (210) supported movably in a radial direction with respect to a rotation shaft 1 that inputs or outputs power and a movement mechanism radially moving the pinion sprockets (210) in synchronization with each other while maintaining equidistance of the pinion sprocket (210) from a shaft center (C 1 ) of the rotation shaft 1, and a chain wound around the two composite sprockets. Transmission ratio is changed by changing a circumcircle radius that is a radius of a circle encircling and circumscribing all the pinion sprockets (210). The pinion sprocket (210) is formed into a sector gear shape having a teeth portion (212) that is arranged along a circumference of a minimum radius circumcircle (A 1 ) and meshes with the chain. With this configuration, torque can surely be transmitted.

摘要： The invention relates to a fitting (10), in particular for a motor vehicle seat, having a first fitting part (11), on which a gear rim (17) is formed, a second fitting part (12) on which a gearwheel (16) is formed, wherein the gearwheel meshes with the gear rim (17), whereby the two fitting parts (11, 12) are in geared connection with each other. The fitting also has a rotatably mounted, revolving eccentric driven by a driving element for driving a relative rolling motion of gearwheel (16) and gear rim (17), wherein during this rolling motion a tooth flank (16d) of a tooth (16a) of the gearwheel (16) rests against a tooth flank (17d) of a tooth (17a) of the gear rim (17) at a contact point (K). The tooth flanks (16d, 17d) of the teeth (16a, 17a) of the gearwheel (16) and gear rim (17) resting against each other at the contact point (K) each follow the course of a portion of a respective logarithmic spiral.

The gear assembly (1) comprises a first gear (3) and a second gear (5). The gear assembly (1) is designed in such a manner that first gear tooth (7) and the second gear tooth (9) are contacted properly to each other in a plane of action when operated in a predetermined condition.

摘要： A transmission gear has a tooth surface formed of a free-form surface instead of an involute surface and a root area formed of a free-form surface instead of a trochoid surface. With such a transmission gear, the fatigue strength against bearing pressure can be increased by reducing the Hertzian stress in the area around the meshing point of the tooth surface, and the fatigue strength against bending can be increased by reducing the bending stress at a tooth root portion of the bottom land. In addition, the gear noise can be reduced. The tooth surface is formed of a free-form surface in which the smallest radius of curvature in an area around a mating pitch point is maximized. The bottom land is formed of a free-form surface in which the smallest radius of curvature in an area around a tooth root is maximized.
