Calibrated pitch change link

摘要

A calibration device for a pitch change link (10) for a helicopter rotor grip where the link (10) includes a bearing (12) and includes a plurality of sequential reference numbers (22) equally spaced apart and concentrically disposed around the link (10). An indexing device (30) is mounted to the bearing (12) and is disposed adjacent to the plurality of sequential reference numbers (22) for locating one of the plurality of reference numbers (22) representing the length of the link (10). The indexing device (30) includes a window (40) which indexes one of the plurality of reference numbers (22) as the link (10) rotates.
