Definitions

  • the present invention relates to devices for controlling the operating conditions of turbomachines and, more particularly, to devices for adjusting the angle of the guide blades of turbomachines.
  • the driven elements permanently connected to the guide blades are essentially driven gears which are in constant mesh with a sun wheel to which is imparted motion from the drive mechanism.
  • motion is imparted to the sun wheel from the drive mechanism.
  • the driven gears which are in constant mesh with the sun wheel make, together with the guide blades, a turn through a present angle relative the flow of the working fluid.
  • kinematic train connecting the guide blades to the drive mechanisms like any other kinematic train comprising links in gear mesh, embodies free play which affects unfavorably the service life of the known devices.
  • the main object of the present invention is to prorespective one of the drive links of the drive mechanism.
  • one drive link of the drive mechanism is adapted to impart to the links of the kinematic train connecting the drive mechanism with the guide blades, a motion which provides for the turning of the guide blades through a preset angle relative the flow of the working fluid, while the other drive link is adapted to impart another motion independent of the motion and creating a force making for the elimination of free play in the kinematic train.
  • each of the blades is permanently connected with its driven element, i.e. a driven gear 2, for their joint turning resulting from the effect of a drive mechanism upon the driven elements.
  • the driven elements are series connected in a kinematic train by means of intermediate idler elements, i.e. intermediate gears 3, while a drive mechanism A is adapted to effect an independent turning of the adjacent driven elements in opposite directions. The resulting expanding force results in the elimination of free play in the kinematic train.
  • the drive mechanism A has two drive links 4 and 5 rotating in opposite directions as indicated by the arrows.
  • the kinematic train connecting the guide blades 1 with the drive mechanism A comprises the series arranged driven gears 2 and the intermediate gears 3 which are in constant mesh and is open in its portion B between two advide a device for adjusting the angle of inclination of jacent driven gears guide blades of turbomachines, in which provision is made for the elimination of free play in the kinematic train connecting the guide blades with the drive mechanism.
  • the drive mechanism has two drive links of opposite rotation while the kinematic train, which comprises series arranged driven and intermediate gears which are in constant mesh, is open in its portion between two adjacent driven gears, with each of the latter driven gears being connected with the Each of the two adjacent driven gears 2 is connected with the respective one of the drive links 4, 5 of the drive mechanism A.
  • the first drive link 4 imparts lefthand rotation to the links of the kinematic train, and the second drive link 5 a right-hand rotation.
  • the device according to the present invention operates in the following manner:
  • the drive link 4 of the drive mechanism A imparts left-hand rotation to the gears 2 and 3.
  • the blades 1 permanently connected to the gears 2 turn through a preset angle relative the flow of the turbomachine working fluid.
  • the drive link 4 is stopped.
  • the links of the kinematic train are caused to turn in a direction opposite to that of their previous turning, thus resulting in the emergence of an expanding force providing for the elimination of free play in the gear mesh.
  • the drive link 5 is likewise stopped.
  • a device for adjusting the angle of inclination of guide blades of turbomachines relative the flow of a working fluid comprising: driven elements each of said driven elements being permanently connected with one of said guide blades with a possibility for their joint turning; intermediate idler elements providing a series connection of said driven elements in a kinematic train; and a drive mechanism operably connected to one pair adjacent driven elements of said kinematic train whereby activation of one drive mechanism effects rotation of the driven elements and idler elements and hence the blades in one direction through a preset angle relative to the flow of working fluid and upon deactivation of said one mechanism and activation of the other mechanism there is effected a rotation of said driven and idler elements in the other direction with the resulting expanding force making for the elimination of free play between the driven and intennediate elements in said kinematic train.
