Definitions

  • a machine of this type is described in the patent FR 2,588,617 , on behalf of the same applicant, to realize an axial piston pump.
  • An external motor rotates the input shaft of the device which converts this rotational movement into an alternating translational movement to pistons arranged parallel to the axis of rotation of the input shaft.
  • This machine uses an oscillating plate guided by a spherical bearing whose reliability needs to be improved. It is found that the lubrication of the spherical bearing is difficult to ensure completely satisfactory which has a negative impact on the life of the machine.
  • the sleeve is rotated by the thrust plate and the male spherical bearing can be rotated by the sleeve, via keys.
  • the axial forces are transmitted to the male spherical bearing 10, to the female spherical bearing 14, to the swash plate 15 and then to the thrust plate 9 via the roller stop 16.
  • the thrust plate 9 is even in abutment on a shoulder 6e provided at the end of the sleeve 6.
  • the shoulder 6e also makes it possible to secure the sleeve 6 and the thrust plate 9 by means of fastening screws (not shown).
  • mounting the thrust plate 9 on the sleeve 6 is by a tight assembly in addition to the key 6a.
  • a reaction rod 18 ( Fig. 2 ) is set to prevent the rotation of the swash plate 15 about the axis xx 'while allowing its oscillation.
  • a first end of the reaction rod 18 is articulated to the frame 2 and a second end is articulated to the swash plate 15.
  • the operation is as follows.
  • the input shaft 12 drives the pinion 13 in rotation.
  • the pinion 13 meshes with the wheel 11 which rotates the thrust plate 9 by means of the pins 11a.
  • the thrust plate 9 rotates the sleeve 6 by means of the key 6a.
