Abstract
A drive system has a gearbox, comprising a passage therethrough, a coupling shaft disposed at least partially within the passage and a first coupling carried by a first end of the coupling shaft. The first coupling is configured to accommodate misalignment. The drive system also has a second coupling carried by a second end of the coupling shaft. The second coupling is also configured to accommodate misalignment.
Claims16
A drive system, comprising:
- a gearbox, comprising a passage therethrough;
- a coupling shaft disposed at least partially within the passage;
- a first coupling carried by a first end of the coupling shaft, the first coupling being configured to accommodate misalignment;
- and
- a second coupling carried by a second end of the coupling shaft, the second coupling being substantially similar to the first coupling and substantially similarly configured to accommodate misalignment;
- wherein the first coupling is disposed external to the gearbox and axially beyond a first axial extent of the gearbox and wherein the second coupling is disposed external to the gearbox and axially beyond a second axial extent of the gearbox.
3 more elements
A drive system, comprising:
- a main rotor gearbox (MRGB);
- an intermediate gearbox;
- and
- a coupling shaft for connecting the MRGB to the intermediate gearbox, the coupling shaft being at least partially disposed within an interior passage of the intermediate gearbox;
- wherein the intermediate gearbox is disposed axially between the MRGB and a drive system component;
- and
- wherein a first coupling configured to accommodate misalignment and a substantially similar second coupling are disposed external to the intermediate gearbox so that the intermediate gearbox is disposed axially between the first coupling and the second coupling.
