Definitions

  • the invention relates to a housing comprising a device for stopping the rotation of a toothed wheel.
  • Stopping devices are known in rotation of a toothed wheel rotatably mounted about an axis of rotation in a housing of a housing.
  • An example of such a device is mentioned in the document FR 2,792,679 , which relates to an electromagnetic actuator comprising an adjusting device equipped with a gear wheel rotatably mounted in a housing of the actuator housing.
  • the bottom of the case is normally attached to the cylinder head of an engine so that it is not possible to access the gear directly.
  • a recess in the bottom, opening on the one hand in the housing of the toothed wheel and on the other hand on one side of the housing, allows radial access to the toothed wheel for a stop device in rotation thereof.
  • the device for stopping the rotating toothed wheel consists of a detachable pawl introduced into the housing of the toothed wheel, this pawl having teeth which cooperate with the teeth of the toothed wheel in order to stop the latter in rotation.
  • the pawl is provided with a lug carried by an elastically deformable support for the engagement of the lug in a notch, in order to immobilize the pawl on the housing.
  • rotation stop devices are also known for a toothed wheel comprising a finger mounted on a body carrying the wheel to be movable radially facing the toothed wheel against a means of rotation. return to the gear wheel.
  • This type of device allows automatic return of the device in the stop position of the gear wheel after its operation, thus eliminating any uncertainty as to the proper positioning of the device.
  • the operation of this stop device requires that one can access laterally the locking finger so that this type of stop device is not usable in the state when it is arranged in the bottom of a well as mentioned in the document FR 2,792,679 supra.
  • a housing according to claim 1 is provided.
  • the housing comprises a device for stopping a rotation of a toothed wheel rotatably mounted about an axis of rotation in a housing.
  • the device is easily operable using a tool introduced into the access channel along the side of the housing from which the operating member is projecting. By removing the tool, the device returns to its initial position and the finger is biased towards the toothed wheel.
  • the biasing means comprises a flexible blade disposed in the housing for bending in a plane normal to the axis of rotation of the toothed wheel, the blade having an anchoring end connected to the housing, the operating member being formed by a section of the blade.
  • the blade comprises two rectilinear branches substantially at right angles connected by the section forming the operating member, one of the branches extending as far as the toothed wheel in a radial direction to constitute the finger, the another branch forming the finger restoring means.
  • a housing 1 comprises in known manner a bottom 2 having a housing 3 of a toothed wheel 4 rotatably mounted on the housing 1 about an axis of rotation X perpendicular to the bottom 2.
  • the bottom 2 of the housing 1 is normally attached to a mechanical element not shown and a housing 101 is attached to the housing 1 preventing access to the toothed wheel 4 in a radial direction thereof.
  • an access channel 20 extends between the two housings parallel to the axis X between the sides 17 and 117 facing the housings 1 and 101.
  • the housing 1 is equipped with an angular stop device of the toothed wheel 4, here a flexible blade 5 mounted on the housing 1 facing the toothed wheel 4 to bend in a plane normal to the axis X.
  • the flexible blade 5 has a bent anchor end 6 engaged in a groove 7 of corresponding shape of the bottom 2.
  • the anchoring end 6 is connected to a first branch 8 of the blade 5 housed in a groove 9 of the bottom 2 having a width sufficient to allow flexion of the branch 8.
  • the branch 8 is connected to a section 10 projecting from the side 17 of the housing 1, so that the end of a tool not shown in this figure can be introduced into the access channel 20 between the side 17 and the section 10.
  • the section 10 is also connected to a second branch 11 substantially perpendicular to the branch 8.
  • the branch 11 has a recess 18 at its junction with the section 10 so as to increase the space available between the section 10 and the housing 1 for the introduction of the end of a tool.
  • the second branch 11 extends towards the toothed wheel 4 in a radial direction in a groove 12 of the bottom 2 opening into the housing 3.
  • the arm 11 has a free end here shown engaged in a recess between two teeth of the toothed wheel 4 .
  • the slope of the flanks of the teeth of the toothed wheel 4 is such that it does not allow a radial clearance of the end 14 of the recess in which it is engaged under the effect of a rotation of the toothed wheel 4.
  • the branch 11 thus constitutes a locking finger in rotation of the toothed wheel 4.
  • the groove 12 is equipped with a guide neck 13 in the vicinity of the housing 3, preventing transverse movement of the free end 14, but does not prevent radial movement of the latter.
  • the operation of the angular arresting device is as follows: when it is desired to release the toothed wheel 4 in rotation, a flat tool is slid along the casing 1 into the access channel 20, so as to introduce its end 15 visible in Figure 2 between the section 10 and the housing 1. Then causes a separation of the section 10 relative to the housing 1 by rotating the end 15 about an axis parallel to the X axis.
  • the first branch 8 then takes an arrow f indicated in Figure 3.
  • the end 14 of the branch 11 is driven by this bending substantially in a radial direction to move away from the toothed wheel 4 by an amount equal to the arrow f of the branch 8, while being guided by the guide neck 13.
  • the free end 14 is then released from the hollow between two teeth of the toothed wheel 4 in which it was engaged, and the toothed wheel 4 is free to rotate. It is then possible to rotate the toothed wheel in a manner known per se from the document FR 2,792,679 .
  • the flat end 15 is operated in the opposite direction.
  • the first branch 8 then acts as a return spring to gradually return the branch 11 to the toothed wheel.
  • the free end 14 then enters again into a hollow between two teeth of the toothed wheel 4.
  • the branch 8 has a direction inclined with respect to the side 17, thereby increasing the length of this branch, and therefore increase its elasticity.
  • This arrangement makes it possible to have an arrow sufficient to bring out the end 14 of a recess between two teeth of the toothed wheel 4.
  • This arrangement allows an optimal installation of the stopping device, between a recess 19 of the bottom 2 provided for the passage of a toothed sector of operation of the toothed wheel 4, and a bore 21 for an assembly dowel of the housing.
  • the anchoring end 6 has a bent portion 16 having a direction parallel to the side 17, which allows to retain the blade 5 in position against the spreading force imposed by the tool on the blade 5 .
  • the structure of the housing according to the invention makes it possible to automate the operation of the stop device.
  • the angular stop device equips an electromagnetic actuator of the type described in FR 2,792,679
  • the unlocking tool can be integrated into an actuator adjustment bench which furthermore comprises means for actuating the toothed wheel.
  • the operating member has been described as a rectilinear section 10 integrated with the flexible blade 5, it can be used an actuator having any type of shape for the passage of an operating tool. It will also be possible to produce an actuator having an oblique portion with respect to the side 17 of the casing, so that the mere insertion of a tool into contact with this oblique part causes the finger 11 to disengage.
  • gearwheel has been described as being housed in a housing on the underside of a housing, the stopper also applies to a gearwheel installed in an interior housing of the housing that can be accessed by a channel made in the housing.
