An apparatus includes a rotating drive component for a drive train, the rotating drive component comprising a first rotating element and a second rotating element, wherein the first rotating element and the second rotating element are arranged in a concentric arrangement such that the second rotating element is positioned within the first rotating element; and a shear element extending radially between and coupled to each of the first rotating element and the second rotating element, the shear element having a lower breaking strength than other components in the drive train, wherein if the shear element breaks, the first rotating element and the second rotating element are decoupled from each other and rotate independently of each other.

An output assembly for an accessory system of a gas turbine engine includes a first rotating member extending along an axis and including a mechanical connector for coupling the output assembly to an accessory system. The output assembly also including a second rotating member extending along the axis, the second rotating member coupled to the first rotating member at a first axial position and at a second axial position, the second rotating member coupled to the first rotating member at the second axial position through a one-way clutch. Additionally, the first rotating member of the output assembly further includes an extension member extending at least partially between the first axial position and the second axial position, the extension member including a designed fail point.

A planetary gearbox system with a ring gear, a sun gear, a carrier and planetary gears as parts in a geared aircraft turbofan engine, with one static part of the parts being in rest under nominal operation and with a kinematic switch device for decoupling the static part to become a rotatable part or with a kinematic switch device for coupling the rotatable part to become a static part. The invention also relates to a method for operating a planetary gearbox system.

A drive element for an electrical connector comprises a gear wheel and an overload coupler. The overload coupler is between the gear wheel and a hub.

An attachment assembly for connecting an actuator to a frame, a method for manufacturing this attachment assembly and a method for reducing backlash in an attachment assembly. The attachment assembly comprises: an outer yoke having a first end and an opposite second end and defining an internal cavity at said second end. The outer yoke has an aperture provided at its second end connected to the cavity; and an inner yoke located within the cavity. A tie bar having a ball shaped end extends through said aperture such that the ball shaped end is positioned within the cavity and cannot pass through the aperture. A spring is provided at said first end of said outer yoke that is configured to bias the inner yoke in the direction of the aperture. The attachment also includes shearable means for holding the inner yoke.

An agricultural machine includes at least one processing device for harvested material and a drive train for the at least one processing device. The drive train has an output transmission stage with an output shaft for the at least one processing device. The output transmission stage includes an input gear and a grooved shaft connected in a non-rotatable manner to the input gear and the output shaft in such a manner that a drive connection between the input gear and the output shaft is achieved via the grooved shaft. The grooved shaft is provided with a ring groove defining a predetermined breaking point. The ring groove is configured in the drive flow direction between the input gear and the output shaft, and the grooved shaft is accessible through an assembly opening on an input gear side of the grooved shaft. The assembly opening is axially aligned with the grooved shaft.

A drive element for an electrical connector comprises a gear wheel and an overload coupler. The overload coupler is between the gear wheel and a hub.

An actuator for a flight control surface of an aircraft, including: a fixed annulus for fixing to the fuselage, an rotatable annulus with respect to the fixed annulus about an axis of rotation, an output ring which can be fixed to the control surface, and a coupling mechanism having a disc with translational mobility with respect to the mobile annulus in a direction parallel to the axis of rotation, the disc able to move between an engaged position, and a disengaged position, in which the disc is disengaged from the mobile annulus to disconnect the output ring from the mobile annulus. A retaining piece keeps the disc in the engaged position, and a rupture member activates to break the retaining piece to allow the disc to move into the disengaged position.
