- the present invention relates to the general field of gas turbines and more particularly relates to the control of a starter-generator.
- the field of application of the invention is that of gas turbines for aircraft engines or helicopters, as well as for auxiliary power units (or APU for "Auxiliary Power Unit”).
- gearbox In a gas turbine, a number of equipment, or accessories, are driven by a mechanical transmission from a mechanical power taken from a turbine shaft.
- This mechanical transmission which is called gearbox or accessory relay box, comprises a set of gears housed in a housing and mechanically coupled to accessories.
- These include various pumps for the production of hydraulic power, fuel supply and lubrication, as well as, in some applications, one or more starters-generators (or S / G for "Starter / Generator").
- S / G for "Starter / Generator”
- S / G operates as an electrical generator and produces a voltage that powers one or more electrical power distribution centers for the aircraft and its engine (s).
- an S / G can function as a starter by being powered by an external power source in order to start the gas turbine by rotating the gas turbine.
- the turbine shaft to which the gearbox is connected can function as a starter by being powered by an external power source in order to start the gas turbine by rotating the gas turbine.
- the meshing ratio between the turbine shaft and the S / G is therefore chosen to offer a possible compromise between the operations of the S / G as a starter and as a generator.
- the generator mode conditions the gear ratio to the detriment of the starter mode.
- the main object of the present invention is therefore to overcome such drawbacks by proposing a device for changing the transmission ratio between the turbine shaft and the shaft of a starter-generator that does not require the use of a control device. .

- the invention provides to take advantage of the operating points of the motor for which the sum of the torques between the turbine shaft and the shaft of the motor. starter-generator changes sign. These operating points correspond to the moments when the starter-generator shaft moves from leading to driven (vis-à-vis the turbine shaft) and vice versa, that is to say during transitions between the two. operating modes of the starter-generator during engine start and stop.
- the transmission ratio change of the device according to the invention is carried out automatically, that is to say that it does not require a particular control device (of the electric or hydraulic actuator type) for this operation (the shift point is controllable by the torque level of the starter-generator). The result is a reliable device, low mass and low cost.
- the lateral faces of the switching sleeve each carry jaws, each clutch having a first planar face which is intended to engage against a planar face of torque transmission of teeth carried by the idle gears when the sleeve is in position. its coupling positions, and a second plane face opposite to the first face which is intended, when the sum of the torques between the turbine shaft and the starter-generator shaft changes sign, to slide on a planar face of uncoupling of the teeth of the idle gears that is opposite to the torque transmission face.
- the second face of the jaws of the switching sleeve can be substantially parallel to the axis of rotation of the switching sleeve, while the disengagement face of the teeth of the idle gears can be inclined with respect to this axis of rotation in the direction of rotation. said sleeve.
- the disengagement face of the teeth of the idle gears may be substantially parallel to the axis of rotation of the switching sleeve, while the second face of the jaws of the switching sleeve may be inclined relative to this axis of rotation in the direction rotation of said sleeve.
- the first face of the jaws of the switching sleeve and the torque transmission face of the idler pinions teeth are substantially inclined relative to the axis of rotation of the switching sleeve in the direction of rotation of said sleeve. This inclination promotes the maintenance of the sleeve on the idle gears.
