Electrical loading of a user control by rotary to liner conversion of a motor drive using a pulley and pulley line

An electrical loading apparatus for providing a load to a user control member (2, fig 1) such as a stick or pedal of a vehicle (eg. aircraft) simulator converts rotary motion of an electric drive motor 25 to linear movement of a shaft 4. The motor 25 drives a pulley wheel 21 through a reduction gearing system 24. Two pulley lines 22,23 are anchored to the pulley wheel 21 and run in grooves 33, and are also anchored to the shaft 4. One shaft anchor 37 has adjustment screws 38,38a for pre-tensioning and stretch correction. Pulley wheel 21 is accommodated in a recess 1000 in shaft 4 to prevent transverse forces being generated. A lug 32 on the pulley wheel 21 limits rotation by engaging with fixed lugs 31,32. A force sensor (6, fig 1) interfaces between the shaft 4 and control member. Shaft 4 is mounted on sliding bearings 28 to a side plate (50, fig 3) connected to a lower plate 40 attached to the motor 25. Thus a substantially constant loading force can be simply applied.

Alternatively or additionally the lead screw 7 may be pretensioned to avoid compressive loading. The nut 14 may be mounted on four lead screws 7 equiangularly arranged about the axis of a motor drive shaft 23. ...

ACTUATOR UTILIZING EPICYCLIC GEARING

An electric motor driven actuator comprises an electric motor whose rotation causes rotation of a planet carrier carrying planet gears which engage an annulus gear on the inside of a stationary ring. A pinion transmits rotation of the planet carrier to further planet gears which are carried on another planet carrier and engage another annulus inside an axially movable ring. This ring can be moved axially by an armature in dependence on energization of an electro magnetic coil within a housing. When the ring moves towards the first-mentioned, stationary, ring, face teeth which it carries engage face teeth on the latter ring, and the axially movable ring is thus held stationary. Its planet carrier thus rotates and a coupling rotates a shaft which, via a tape, transmits drive to an output cable. When the coil is de-energized rings, separate again and the axially movable ring is no longer held stationary and its planet carrier no longer rotates.
