Definitions

  • the present invention relates to a rotary hydraulic actuator, intended for driving in rotation an element such as an aircraft control surface.
  • this application is not limiting, this actuator being capable of being implemented for driving very diverse elements.
  • Document US-A-3,023,741 describes a hydraulic actuator device comprising a pallet rotatably and sealingly mounted in a chamber formed in a body and on the faces of which a hydraulic fluid pressure can be applied.
  • the pallet is mechanically integral with an element to be driven in rotation and comprises several parts extending radially on either side of its axis of rotation, each part being movable in a chamber divided into two compartments by the aforementioned part of the palette.
  • the device is provided with a hydraulic circuit for supplying the chambers with fluid making it possible to drive the pallet in rotation in one direction or the other.
  • GB-A-1 069 215 describes a rotary actuator with double vanes, comprising a hub integral in rotation with said double vanes and in which is formed an axial recess receiving a shaft integral in rotation with the hub and with an element to be driven.
  • This rotary actuator also comprises an annular body surrounding the paddles and having on its periphery two circumferential grooves forming part of the hydraulic fluid circuit, the paddles and the hub being in sealed sliding contact with the body by seals received in grooves.
  • the object of the invention is to remedy these drawbacks.
  • the device is characterized by the means referred to in the characterizing part of claim 1.
  • the actuator 65 is equipped with a pallet 66 comprising two radial parts 70 diametrically opposite and joined by an annular part 69 and a hub 71 of annular section axially passing through the annular part 69 The latter is secured in rotation with the hub 71 by complementary axial grooves such as 72.
  • any suitable means is provided, such as complementary axial grooves 90, formed on the periphery of the shaft 73 and in the internal wall of the hub 71.
  • a bolt 130 provided with a thread 190 is screwed into a thread in the hub 71, coaxially with the shaft 73, and makes it possible to tighten the bearings 92, 93.
  • the actuator 65 also comprises an annular body 74 surrounding the radial parts 70 and the central part 69, and on the periphery of which are machined two circumferential grooves 75, 76 coaxial with the general axis XX of the actuator.
  • the groove 75 communicates on the one hand with a supply duct 77, 78 formed in an outer casing 79 and a sleeve 80, and on the other hand with two radial ducts 81 drilled in the body 74 and opening into respective chambers 82 , 83.
  • the groove 76 communicates on the one hand with a supply duct 84, arranged in the casing 79 and which opens into a bore 85 of a second sleeve 87, and on the other hand with two ducts radials 86 of body 74, which open into the other two hydraulic chambers 88, 89.
  • Body 74 is provided with an annular seal 74a housed in a body groove formed between the grooves 75, 76.
  • the chambers 82, 83 and 88, 89 are delimited by the body 74 and by the radial parts 70 as well as by the central part 69.
  • the latter as well as the radial parts 70 are mounted in leaktight manner with respect to the body 74 by seals 91, 120 received in respective grooves of the body 74 and of the ends of the radial parts 70.
  • the actuator 65 is also equipped with two bearings 92 for ball bearings 93, interposed between the hub 71 and an annular body 94 contained in the casing 79.
  • the latter is provided with two radial flanges 97, 98 interposed between the radial parts 70 and the bearings 92, which are additionally held in place axially by an end flange 99 of the hub 71.
  • the assembly is closed, on the side opposite to the flange 99, by a cover 101 held by fixing screws 102 engaged in the 'envelope 94.
  • FIG 5 shows an actuator 100 identical to the actuator 65, except that its cover 101 is replaced by a flange 103 which receives the end 104 of an electric potentiometer 105 of shaft 73.
  • This potentiometer 105 is provided with a cursor 106 driven in rotation in a manner known per se by the shaft 73 on the resistance of the potentiometer, when this shaft is itself rotated as described above with reference to Figures 1 to 4.
