With the protruding beyond the wall of the housing bore 15 is largely semi-cylindrical part of the bearing pin 16 this in an axially directed groove of the bearing ring 4 added.
- the axial groove is the shape of the bearing pin 16 adapted and also partially cylindrical.
- the one in the axial groove engaging bearing pin 16 therefore forms for the bearing ring 4 one parallel to the axes of pinion 2 and ring gear 3 extending pivot axis about which the bearing ring 4 in Framework of the available radial play in the Housing bore 15 is pivotable.
- this pivot axis lies in a quadrant of the Bearing rings 4, which is between the non-invasive Ring gear area and the center of the pressure chamber extends.
- the openings 8 lead from the pressure chamber to the pressure outlet channel, not shown in the Housing cover 12.
- the housing cover 12 has diametrical a suction inlet duct 9 opposite the pressure outlet duct on, which at its mouth to a suction field 10th expanded.
- a pressure field 31 is indicated by that the respective axial disk 30 from the outside against the Effect of the inner pressure field 7 is applied so that the axial washer sealing contact in all operating states with the pinion 2 and the ring gear 3 maintained. education and mode of action of the pressure fields on axial washers well-known and therefore need at this point no further explanation.
- Each thrust washer 30 supports itself for the purpose of it Secure position on the one hand over the circumference of a bearing bore 33 on the pinion shaft 14 and on the other hand on one in the Housing 11 or the housing cover 12 used pin 34 from.
- the pins 34 each protrude into a blind hole in the outer end face of the axial disks 30 and are thereby held axially.
- Variants are also on the housing by means of the pins 34 conceivable, the movement of the axial discs 30 together allow with pinion 2, ring gear 3 and bearing ring 4 (cf. EP 97-121 424.2 A1).
- Fig. 4 shows the internal gear machine according to the Fig. 1 to 3 running group 20 used, the the pinion 2 and the ring gear 3.
- the ring gear 3 has an outer part designed into a race 35, which forms the outer circumference 36 of the ring gear 3, and one the part 37 supporting the internal toothing.
- the race 35 of the ring gear 3 exceeds Width of the part 37 bearing the internal toothing significant; the raceway width is in this Embodiment about three times the width of the internally toothed part 37.
- the race 35b and the internally toothed part 37b separate components that joined together by pressing, shrinking or gluing are.
- This embodiment allows a different one Choice of materials for the race and the internal gear Part that better adapt to the required storage or Combing properties allowed.
