DEVICE FOR GUIDING VARIABLE PITCH DIFFUSER VANES OF A TURBINE ENGINE |
| 摘要 |
The invention relates to a device for guiding variable pitch diffuser vanes of a turbine engine, the device comprising a first ring (26) having an axial portion (32) at its periphery that is extended by a collar (34) extending radially outwards, a second ring (28) mounted around the axial portion of the first ring so as to co-operate therewith to define a plurality of outwardly open sockets (36), a plurality of cylindrical bushings (22), each mounted in a respective socket for the purpose of receiving a guide pivot (12) of a diffuser vane (4), and a resilient clamping ring (30) for cooperating with one of the rings in order to clamp the two rings axially one against the other. |

1. A device for guiding variable pitch diffuser vanes of a turbine engine, the device comprising:
a first ring having an axial portion at its periphery that is extended by a collar extending radially outwards; a second ring mounted around the axial portion of the first ring so as to co-operate therewith to define a plurality of outwardly open sockets; a plurality of cylindrical bushings, each mounted in a respective socket for the purpose of receiving a guide pivot of a diffuser vane; and a resilient clamping ring for co-operating with one of the rings in order to clamp the two rings axially one against the other. |
