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.
Claims20
A harmonic pin ring gear system comprising:
- an input shaft and an output shaft;
- two outer gears, each with internal toothing,
- a single inner gear with external toothing arranged concentrically to a first outer gear and inside said first outer gear in an axial direction;
- a drive means extending between the two outer gears and the inner gear comprising a pin ring formed as one part in circumferential direction and a multiplicity of pins that protrude laterally in the axial direction from the pin ring;
- and
- a rotary transmitter for lifting the drive means off the external toothing of the inner gear and pressing the drive means into the internal toothing of the outer gear;
- wherein the inner gear comprises an inner gear holder that is fixed to the inner gear and an inner gear roller bearing supported radially inwardly by a gear housing, wherein the inner gear and the inner gear holder encompass an outer ring of the inner gear roller bearing.
A motor vehicle comprising:
- outer gears each with internal toothing;
- an inner gear with external toothing arranged concentrically to an outer gear and inside the outer gear in an axial direction;
- a drive means extending between the outer gears and the inner gear comprising a pin ring formed as one part in circumferential direction and a multiplicity of pins that protrude laterally in the axial direction from the pin ring;
- a rotary transmitter for lifting the drive means off the external toothing of the inner gear and pressing the drive means into the internal toothing of the outer gear;
- and
- a harmonic pin ring drive comprising a gear unit and a motor unit, wherein:
- the inner gear comprises an inner gear holder that is fixed to the inner gear and an inner gear roller bearing supported radially inwardly by a gear housing;
- the inner gear and the inner gear holder encompass an outer ring of the inner gear roller bearing;
- a rotor shaft of a motor of the motor unit is connected mechanically to a cam disk of the gear unit;
- and
- a drive gear of the motor vehicle is connected to an output shaft of the harmonic pin ring drive.
