A harmonic pin ring gear system comprises an input shaft, an output shaft, two outer gears each with internal toothing and a single inner gear with external toothing. The inner gear is arranged concentrically to a first outer gear and in axial direction inside the first outer gear. A drive means extends between the two outer gears and the inner gear and comprises a pin-retaining ring formed as one part in circumferential direction and a multiplicity of pins that protrude laterally in axial direction from the pin-retaining ring. A rotary transmitter lifts the drive means off the external toothing of the inner gear and presses the drive means into the internal toothing of the outer gears.

A harmonic drive has an outer gear, an elliptical follower hub, and an outer chain coupled to the follower hub, and having teeth that mate with the outer gear. Preferred embodiments further include an inner chain disposed such that the follower hub is functionally interposed between the inner and outer chains.

A transfer device is provided with variable rotation angle having an internally toothed ring gear, an externally toothed sun gear, a transmitter element and an adjustable actuation device, wherein the transmitter element comprises a circumferential engagement device arranged between the ring gear and sun gear. The actuation device comprises an activation element that can be moved along the engagement device for rotation angle adjustment. In this case, the circumferential engagement device is partially engaged with the internal toothing of the ring gear and partially engaged with the external toothing of the sun gear by means of the activation element. Moreover, a correspondingly designed camphaser of a combustion engine, and a method for adjusting the relative rotation angle position of the camshaft to the crankshaft in a combustion engine, are provided.

In order to guide supply or construction elements through a harmonic drive (8) in a central manner, said harmonic drive is embodied in a hollow gear. The harmonic drive directly provides a given correcting translatory variable which is defined by the speed of rotation of the output ring and motor driven harmonic generator when the output ring axially displaces a threaded rod (26) which freely extends in a coaxial manner through a longitudinal bore in the harmonic drive and engages with said output ring, said axial displacement occurring as a result of the rotational movement of the inner thread of the output ring, whereby the threaded rod is secured to the housing and prevented from rotating (29, 30). The threaded rod can move in a linear manner in relation to the gear motor (13) when the gear motor is installed in a stationary manner or when the treaded rod is installed in a stationary manner.

A high ratio speed reducer comprising a rotatable input shaft operatively coupled to an output shaft which rotates at a reduced speed in response to rotation of the input shaft. An output sprocket is mounted on the output shaft for rotation therewith, the output sprocket having a circumferential perimeter including a number of teeth. A drive sprocket having a circumferential perimeter including a number of teeth differing by at least one tooth from the number of output sprocket teeth is rotatably mounted with respect to an eccentric end portion of the input shaft and orbits as the input shaft is rotated. Successive segments of the drive sprocket perimeter continuously move outside the output sprocket perimeter as the drive sprocket orbits to advance an endless double chain engaging both sprockets.

Described is a planetary harmonic differential transmission, comprised of a rigid externally-toothed inner sprocket, a rigid internally-toothed outer sprocket, a deformable belt that is toothed on both its internal and external faces, and a set of free-rotating planetary sprockets that are mounted on a rotating carrier cage and cause the belt to progressively engage and disengage from successive portions of the rigid sprockets. The input to the transmission is the relative motion between the carrier cage and the inner sprocket, and the output is the relative motion between the outer sprocket and the inner sprocket, resulting in a differential transmission.
