Abstract
A geared turbomachine has a transmission housing with a upper part and a lower part joined to the upper part along a main joint extending at least in sections perpendicular to a vertical direction. A main gear is in the transmission housing and a first pinion cover is connected to the upper part along a first pinion joint consisting of a first horizontal section extending perpendicular to the vertical direction and a first vertical section extending from the first horizontal section at a first angle. A first pinion shaft has a first shaft body in the first pinion joint and in the transmission housing and carries a first pinion meshing with the main gear. A first turboimpeller is fixed to the first shaft body.

A geared turbomachine comprising
- a transmission housing having
- a stepped upper part forming a plurality of receptacles and
- a lower part joined to the upper part along a main joint having planar sections perpendicular to a vertical direction;
- a main gear received in the transmission housing and rotatable therein about a horizontal axis;
- respective pinion covers seated in the receptacles and connected to the upper part along respective L-shaped first pinion joints each consisting of
- a first planar horizontal section extending perpendicular to the vertical direction and offset vertically from the main joint and
- a first planar vertical section extending from the first horizontal section at a first angle, the pinion joints being offset from and not crossing the main joint a single respective pinion shaft in each of the;
- pinion joints and rotatable in the respective pinion joint about a respective axis parallel to the horizontal axis of the main gear;
- respective pinions on the pinion shafts and meshing with the main gear;
- and
- respective turboimpellers fixed to the shafts.
