Means for preventing the rotation of a pin supporting a turbine engine suspension member
View Patent ↗A device for mounting a suspension member on the casing of a turbine engine is disclosed. The device includes a yoke with at least one lug, secured to the casing, a pin fixed to the yoke supporting the member via a ring surrounding the pin, and a rotation-prevention device that includes a counter-rotation plate attached to the lug. The plate and the pin include an assembly consisting of a peg and of a cutout or a hole, into which the peg fits in order to prevent the pin from rotating in the yoke.
1. A device for mounting a suspension member on the casing of a turbine engine comprising:
a yoke with at least one lug, secured to the casing;
a pin fixed to said yoke supporting said member via a bushing surrounding the pin, an end of the pin includes a step on which a flat surface is formed and a first side of the bushing including a step which abuts a first side of the yoke in an axial direction; and
a counter-rotation plate attached to the lug, a first side of the plate abuts a second side of the yoke and a second side of the bushing in the axial direction,
wherein a second side of the plate includes a counter-rotation tab with a surface against which the flat surface of the step of the end of the pin abuts.
2. A device for mounting a suspension member on the casing of a turbine engine comprising:
a yoke with at least one lug, secured to the casing;
a pin fixed to said yoke supporting said member via a ring surrounding the pin; and
a rotation-prevention means comprising a counter-rotation plate attached to the lug,
wherein said plate and the pin comprise an assembly consisting of a peg and of a cutout or a hole, into which said peg fits in order to prevent the pin from rotating in the yoke, and
wherein the plate is prevented from rotating relative to the yoke by a bolted connection.
3. The device as claimed in claim 2 , wherein the bolted connection consists of a screw passing through the plate and the lug and held in place by a nut.
4. A turbine engine casing comprising at least one yoke with at least one lug comprising at least one device for mounting a suspension member as claimed in one of claims 1 to 3 .
5. A turbine engine comprising at least one device for mounting a suspension member as claimed in one of claims 1 to 3 .
6. The device as claimed in claim 1 , wherein the counter-rotation tab is of rectangular shape.
7. The device as claimed in claim 1 , further comprising a screw which passes longitudinally through the pin.
