Tool for assembling a stator ring of a turbomachine

摘要

The device is designed to assemble a distributor ring before it is fitted to a turbine rotor. It consists of a circular plate (5) with assembly units for the distributor sectors (8). Each unit has a suspension mechanism (60,61) to support the sector relative to the plate. A mechanism (92,93) controls the angle of the sectors relative to the plate and their surrounding housing. Each suspension mechanism consists of a pair of arms (60,61) pivoted to a support. One of the arms (61) is also articulated to the edge of the circular plate. The other (60) arm, to a component (92) of the angle control mechanism which is common to all the assembly units. The control mechanism comprises a nut (93) screwed onto a threaded axle (52) of the circular plate and containing a rotary crown ring (92).
