SLOTTED DAMPER PIN FOR A TURBINE BLADE |
| 摘要 |
A damper pin for damping adjacent turbine blades coupled to a rotor shaft includes an elongated body having a center portion disposed between a first end portion and a second end portion. The first end portion, center portion and second end portion define a generally arcuate top portion of the elongated body that is configured to contact with a groove defined between the adjacent turbine blades. The elongated body includes a first side portion laterally opposed to a second side portion and defines a plurality of laterally extending slots. The slots are axially spaced along the center portion and each slot extends at least partially through at least one of the first side portion or the second side portion. |
