Rotor blade pulling-off tool |
摘要 |
A turbine blade mounting with an improved pulling system for removing and fitting of the blade has the blade foot (3) sliding axially in a keyway (6) on the hub via a profiled grip (5) under the base. A puller (14) braced on the hub engages a lipped grip (7) on one side of the blade base to pull the blade along the keyway using a threaded drive. The blade is withdrawn without use of hammers and without damage to the interlocking grip and keyway. The lipped puller grip has a recess in the blade base fitted with lipped bottom edge formed by a rear groove. |
