METHOD FOR CONNECTING THE ROTOR OF AN ELECTRIC MOTOR TO AN ELEMENT THAT IS TO BE DRIVEN

The invention relates to a method for connecting in rotation an output member (5) of an electric motor (1) and an element (2) that is to be driven in rotation, comprising the use of at least one fusible pin (11) that links the output member and the element that is to be driven, and that has at least one section that is prone to fail in shear when a torque transmitted by the fusible pin exceeds a predetermined threshold. The method comprises the step of interposing, between the pin and either the output member or the element that is to be driven, at least one elastic member (20) comprising a first travel with a first stiffness followed by a second travel with a second stiffness greater than the first stiffness.

09884678 · 2018-02-06 · ·

Known autonomous taxi systems for aircraft include a rigid connection between the aircraft wheel and a gear which is used to drive it. Such arrangements have been found to suffer from the problem that wheel deformation modes cause unacceptable wear and/or stresses within the drive system and/or wheel. The present invention thus proposes a drive system for an aircraft landing gear, the drive system comprising: a pinion gear; a drive shaft arranged to rotate the pinion gear about a drive axis; a driven gear arranged to mesh with the pinion gear to be rotatable by the pinion gear, the driven gear being connectable to a wheel of the landing gear to be capable of rotating the wheel about a wheel axis; and a flexible interface. The flexible interface comprises a plurality of driven gear coupling members, each driven gear coupling member having a first connection portion attached to the driven gear, a second connection portion adapted to be attached to the wheel at an offset distance from the wheel axis, and a joint between the first connection portion and the second connection portion, the joint permitting relative movement between the first connection portion and the second connection portion.

20180003262 · 2018-01-04 ·

A torque transfer mechanism includes an input member to receive an input torque from a propulsion source, and an output member coupled to the input member to transfer the input torque to a driveline component. A multi-component damping mechanism is disposed between the input member and the output member which includes a first spring element cooperating with a second spring element to couple the input member to the output member. The first spring element defines a greater stiffness and shorter deflection relative to the second spring element.

A flexible coupling includes an input body, an output body offset from the input body, and a flexible lattice body. The flexible lattice body includes a flex beam member coupling the input body to the output body. The flex beam member has a rounded cross-sectional area with a centrally disposed minimum cross-sectional area to reduce peak stress in the flex beam member while transferring torque and accommodating misalignment between the input body and the output body. The flexible coupling is jointless, simplifying fabrication, and has a free-form geometry, reducing weight.

A torque coupler includes a first torque plate having a first slot extending in a radial direction, and a second torque plate having a second slot extending in the radial direction. The second slot has a side formed of a flexible beam. A cam plate is pivotable about an axis, and has a cam slot having a first portion at a first radial distance from the axis and a second portion at a second radial distance, where the second distance is greater than the first distance. A torque transfer member is slidably received within the first slot, the second slot, and the cam slot. The transfer member transferring torque between the first and second torque plates. A drive device rotates the cam plate about the axis, which causes the first cam slot to radially slide the transfer member along the flexible beam.
