Abstract
A landing gear system and method of actuating the landing gear system, the system including a first leg assembly, a second leg assembly, a cross-shaft arranged between the two leg assemblies, and a landing gear actuator. The landing gear actuator includes a motor and a coupling shaft which is arranged to couple and decouple the landing gear actuator from the cross-shaft.
Claims14
A landing gear actuator assembly, comprising:
- a housing having a cavity, the cavity comprising;
- a worm hub operatively arranged to rotate about a first imaginary rotational axis and within the cavity of the housing, the worm hub having a first outer circumferential surface having a first plurality of gear teeth arranged thereon, a first through-bore substantially parallel with the first imaginary rotational axis, a first axial worm hub portion, and a second axial worm hub portion, the first axial worm hub portion further comprising an annular recess arranged about the first imaginary rotational axis, and the second axial worm hub portion comprising the first through-bore;
- a worm gear having a second outer circumferential surface having at least one gear tooth arranged to engage with the first plurality of gear teeth of the worm hub;
- and,
- a coupling shaft arranged through the housing and within the first through-bore of the worm hub and substantially parallel to the first imaginary rotational axis;
- a motor arranged to provide a first rotational force to the worm gear;
- and,
- wherein, the first rotational force of the motor induces a rotation of the worm gear within the housing and transfers the first rotational force to the worm hub, and
- wherein the housing further comprises a first input port for receiving a first input.

- and,
- a cross-shaft arranged between the first leg assembly and the second leg assembly;
- and,
- a landing gear actuator assembly secured to the first leg assembly, the second leg assembly, or the cross-shaft the landing gear actuator assembly comprising:
- a housing having a cavity, the cavity comprising:
- a worm hub operatively arranged to rotate about a first imaginary rotational axis and within the cavity of the housing, the worm hub having a first outer circumferential surface having a first plurality of gear teeth arranged thereon, a first through-bore substantially parallel with the first imaginary rotational axis, a first axial worm hub portion, and a second axial worm hub portion, the first axial worm hub portion further comprising an annular recess arranged about the first imaginary rotational axis, and the second axial worm hub portion comprising the first through-bore;
- a worm gear having a second outer circumferential surface having at least one gear tooth arranged to engage with the first plurality of gear teeth of the worm hub;
- and,
- a motor arranged to provide a first rotational force to the worm gear;
- and,
- a coupling shaft through the housing and within the first through-bore of the worm hub and substantially parallel to the first imaginary rotational axis, wherein the coupling shaft is arranged to couple and decouple the motor from the cross-shaft;
- wherein, the first rotational force of the motor induces a rotation of the worm gear within the housing and transfers the first rotational force to the worm hub, and
- wherein the housing further comprises a first input port for receiving a first input.
