Abstract
A harmonic drive (1) comprises three connection elements (2, 9, 13), namely an input element (2), an output element (13) and an adjusting element (9), and an anti-twist mechanism (15) operates between the connection elements (2, 9, 13), the anti-twist mechanism comprising an anti-twist element (18), which is concentric to the connection elements (2, 9, 13) and interlockingly cooperates with one of the connection elements (9) and frictionally cooperates with one other connection element (2).
Claims19
A harmonic drive comprising:
- an input element,
- an output element,
- an adjusting element, and
- an anti-rotation device including a securing ring configured to interlockingly cooperate with the adjusting element and frictionally cooperate with the input element so as to prevent rotation of the adjusting element relative to the input element.
A method for rotationally locking a harmonic drive, the method comprising:
- providing the harmonic drive, the harmonic drive including:
- a rotatable housing, and
- a wave generator including an adjusting element,
- providing a securing ring configured as a rotational lock, and
- inserting the securing ring between the adjusting element and the housing such that frictional cooperation between the securing ring and the housing, and an interlocking cooperation between the securing ring and the adjusting element prevent rotation of the adjustment element relative to the housing.
A harmonic drive comprising:
- a housing,
- a wave generator including an outer ring and an inner ring forming a raceway,
- a plurality of balls arranged between the inner ring and the outer ring,
- an externally toothed flex ring arranged around the outer ring,
- an output gear configured to engage with the externally toothed flex ring, and
- a removable securing ring configured to interlock with the inner ring and to frictionally engage the housing so as to prevent rotation of the inner ring relative to the housing.
