GRADIENT MEASURING JIG OF BLADE

摘要

PURPOSE: A gradient measuring jig of a blade is provided to measure the gradient of a blade rapidly and conveniently right after the blade is assembled to the outer circumferential surface of a turbine rotor. CONSTITUTION: A gradient measuring jig(100) of a blade comprises a body, first and second rollers(122,124) and a gauge(130). A reference probe(120) is arranged on the body to make contact with one side of the blade(200). The lower part(118) of the body is held in the T groove(310) of the turbine rotor. The first and second rollers are installed on one side of the body, and an axis is arranged in a direction orthogonal to the reference probe. The first and second rollers make rolling-contact with the outer circumferential surface of the turbine rotor. The gauge is installed on the upper part of the body, and the blade and the probe(132) make contact to indicate measurement.
