Abstract
A controllable variable length link device is disclosed. The device includes a first half-link having a first end connected to a driving system and a second end, a second half-link having a first end connected to a driven system and a second end, a rotary displacement member including a rotator shaft and a rotary head cooperating with the second ends of the half-links to bring about opposite movement of the half-links, a bearing unit in which the rotator shaft is mounted, respective guiding units which guide the two half-links in translation in at least two parallel directions, the guiding units being mechanically connected to the bearing means; and a driving unit which drives the shaft in rotation in both directions in accordance with a predetermined relationship.
Claims15
A controllable variable length link device comprising:
- a first half-link including a first end connected to a driving system and a second end;
- a second half-link including a first end connected to a driven system and a second end;
- a rotary displacement member including a rotator shaft and a rotary head cooperating with said second ends of said half-links to bring about opposite movement of said half-links;
- a bearing unit in which said rotator shaft is mounted;
- first and second guiding units which guide said first and second half-links, respectively, in translation in at least two parallel directions, said guiding units being mechanically connected to said bearing unit;
- and
- a driving unit which drives said shaft in rotation in both directions in accordance with a predetermined relationship, by which the length of the link may be varied based on the rotation of said shaft, when said link device is operating.
A variable pitch guide vane control device comprising a link device comprising:
- a first half-link including a first end connected to a driving system and a second end;
- a second half-link including a first end connected to a driven system and a second end;
- a rotary displacement member including a rotator shaft and a rotary head cooperating with said second ends of said half-links to bring about opposite movement of said half-links;
- bearing means in which said rotator shaft is mounted
- respective means for guiding said two half-links in translation in at least two parallel directions, said guiding means being mechanically connected to said bearing means;
- and
- means for driving said shaft in rotation in both directions in accordance with a predetermined relationship.
A turbomachine compressor comprising a link device comprising:
- a first half-link including a first end connected to a driving system and a second end;
- a second half-link including a first end connected to a driven system and a second end;
- a rotary displacement member including a rotator shaft and a rotary head cooperating with said second ends of said half-links to bring about opposite movement of said half-links;
- bearing means in which said rotator shaft is mounted;
- respective means for guiding said two half-links in translation in at least two parallel directions, said guiding means being mechanically connected to said bearing means;
- and
- means for driving said shaft in rotation in both directions in accordance with a predetermined relationship.
A turbomachine comprising a link device comprising:
- a first half-link including a first end connected to a driving system and a second end;
- a second half-link including a first end connected to a driven system and a second end;
- a rotary displacement member including a rotator shaft and a rotary head cooperating with said second ends of said half-links to bring about opposite movement of said half-links;
- bearing means in which said rotator shaft is mounted;
- respective means for guiding said two half-links in translation in at least two parallel directions, said guiding means being mechanically connected to said bearing means;
- and
- means for driving said shaft in rotation in both directions in accordance with a predetermined relationship.
