Abstract

The disclosure relates to the technical field of aero-engines, and proposes a centering structure and a turbine test device with it. The centering structure is used to connect the power turbine test piece and the volute. The power turbine test piece is provided with a first installation hole, and the volute The shell is provided with a second mounting hole, the centering structure includes a fastener, a slider and a locking piece, the fastener passes through the second mounting hole and the first mounting hole, and a gap is formed between the fastener and the first mounting hole. Reserve a gap; the slider is set in the reserved gap; the locking piece is detachably connected with the fastener, and abuts against the end of the slider away from the second mounting hole, so that the power turbine test piece and the volute are fixed connect. Fasteners, slide blocks and locking parts can realize the connection of the power turbine test piece and the volute, and can realize the precise centering of the power turbine test piece and the volute, thereby solving the test piece casing in the prior art The problem that the installation side and the volute installation side cannot be centered.

Description

technical field [0001] The present disclosure relates to the technical field of aero-engines, and in particular, to a centering structure and a turbine test device having the same. Background technique [0002] At present, it is necessary to adjust the concentricity between the test piece and the dynamometer before the turbine test to ensure the normal operation of the test piece. However, the prior art is manually adjusted by the operator, but since the change of the position of the dynamometer is realized by plugging the adjusting shim, the entire adjustment is difficult and time-consuming, so it is necessary to reduce the number of test pieces and dynamometers as much as possible Adjustment of concentricity between. [0003] However, in order to facilitate the installation of the test piece in the prior art, the mounting edge of the test piece casing and the mounting edge of the volute are directly connected by bolts, and a large gap is designed between the two openings....
