Planetary gear set having an anti-turn mechanism
View Patent ↗The invention relates to a planetary gear set having an anti-turn mechanism, comprising a sun fear and at least one planet gear revolving in a fear housing having an internal toothing, wherein the gear housing is connected to at least one bearing flange on the output side and/or on the input side, and for the anti-turn connection to the gear housing, toothing means are provided which engage with the internal toothing. According to the invention at least one tooth segment is provided as a toothing means, the tooth segment comprises a tooth segment body, and the bearing flange has an opening for positively receiving the tooth segment body.
1. A planetary gear set having an anti-turn mechanism, comprising a sun gear and at least one planet gear circulating in a gear housing with internal toothing, with the gear housing being connected to at least one bearing flange at an output and/or an input side, and with toothing means being provided for a torque-proof connection to the gear housing, which engage the internal toothing, wherein at least one tooth segment is provided as such toothing means, the tooth segment comprises a tooth segment body, and the bearing flange comprises a recess for a form-fitting acceptance of the tooth segment body, and wherein the bearing flange comprises an annular shoulder at the side of the gear housing, and the tooth segment is arranged in a groove extending radially in the area of the annular shoulder with a groove width adjusted to an arc length of the tooth segment such that the shoulder is aligned to a tooth base of the teeth of the tooth segment.
2. The planetary gear set of claim 1 , further comprising wherein the tooth segment is embodied with an arc-shaped tooth carrier supporting the teeth of the tooth segment.
3. The planetary gear set of claim 2 , further comprising wherein the tooth segment body is arc-shaped in the radial direction with a first and second primary area, with the tooth carrier being arranged on the first primary area with a facial area of the tooth segment extending perpendicularly in reference thereto.
4. The planetary gear set of claim 3 , further comprising wherein the second primary area of the tooth segment body comprises a pin formed thereon, which is accepted by a bore arranged in the bearing flange.
5. The planetary gear set according to claim 1 , further comprising wherein the groove forms the recess for the tooth segment and the groove comprises a depth such that a first primary area of the tooth segment body is aligned to a facial area of the bearing flange at the side of the gear housing.
6. The planetary gear set of claim 1 , further comprising wherein a threaded bore is inserted into the bearing flange in which can be positioned to overlap a partial bore in the tooth segment body.
7. The planetary gear set of claim 1 , further comprising wherein two diametrically opposite tooth segments are arranged on the bearing flange.
