Abstract
A harmonic ring gear system can include at least one inner gear with external toothing, the at least one inner gear defining an axis of rotation; at least one outer gear with internal toothing arranged concentrically to the at least one inner gear about the axis of rotation, the internal toothing spaced apart from the external toothing; a pin ring positioned between the at least one inner gear and the at least one outer gear, the pin ring comprising a multiplicity of pins; and a rotary transmitter configured to lift a portion of the pins of the multiplicity of pins off the external toothing and press the portion of the pins into the internal toothing.

Harmonic-pin ring gear system comprising:
- at least one inner ring with external toothing and
- at least one outer ring with internal toothing,
- a pin ring with pins with a circular cross section,
- a rotor with a transmitter for drawing the pins of the pin ring into the teeth of the outer rings and into the teeth of the inner ring,
- wherein the inner ring, the rotor and the outer ring are arranged concentrically in relation to one another, the transmitter is arranged inside the pin ring and the transmitter and the pin ring are arranged between the inner ring and the outer ring, wherein the transmitter is deformed such that the outer ring and the inner ring rotate in relation to one another,
- wherein, moreover, the shape of the teeth of the outer ring and the shape of the teeth of the inner ring are essentially determined by the envelope of the moving pins and each of the pins is in mesh with the internal toothing of the outer gear or in mesh with the external toothing of the inner gear.
Inner ring with external toothing for a harmonic pin ring gear system comprising a pin ring with pins having a circular cross section, a rotor with a transmitter for drawing the pins of the pin ring into the teeth of the inner ring, wherein the inner ring and the rotor are arranged concentrically in relation to one another and the transmitter is arranged inside the pin ring, wherein the transmitter deforms the pin ring such that the inner ring rotates relative to an outer ring arranged concentrically to the inner ring,
- wherein the inner ring
- comprises tooth bases with a profile in the form of a segment of a circle arranged a regular distances, and
- teeth arranged between the tooth bases, wherein the shape of the teeth is essentially determined by the envelope of the moving pins.
Outer ring with external toothing for a harmonic pin ring gear system comprising a pin ring with pins having a circular cross section, a rotor with a transmitter for drawing the pins of the pin ring into the teeth of the inner ring, wherein the outer ring and the rotor are arranged concentrically in relation to one another and the transmitter is arranged inside the pin ring, wherein the transmitter deforms the pin ring such that the outer ring rotates relative to an inner ring that is arranged concentrically to the outer ring,
- wherein the outer ring
- comprises tooth bases with a profile in the form of a segment of a circle arranged a regular distances, and
- teeth arranged between the tooth bases, wherein the shape of the teeth is essentially determined by the envelope of the moving pins.
