Abstract

The invention relates to the technical field of aero-engines, and provides a centering structure and a turbine test device with the centering structure. The centering structure is used for connectinga power turbine test piece and a volute. A first mounting hole is formed in the power turbine test piece, a second mounting hole is formed in the volute, the centering structure comprises a fastener,a sliding block and a locking piece, the fastener penetrates through the second mounting hole and the first mounting hole, and a reserved gap is formed between the fastener and the first mounting hole; the sliding block is arranged in the reserved gap; and the locking piece is detachably connected with the fastener and abuts against one end, far away from the second mounting hole, of the sliding block so that the power turbine test piece is fixedly connected with the volute. The power turbine test piece and the volute can be connected through the fastener, the sliding block and the locking piece, accurate centering of the power turbine test piece and the volute can be achieved, and thus the problem in the prior art that test piece casing installation edge and the volute installation edge cannot be centered is solved.

Description

technical field [0001] The present disclosure relates to the technical field of aero-engines, in particular to a centering structure and a turbine test device having the centering structure. Background technique [0002] At present, before the turbine test, the concentricity between the test piece and the dynamometer needs to be adjusted to ensure the normal operation of the test piece. However, the existing technology is manually adjusted by the operator, but because the change of the position of the dynamometer is realized through the plug adjustment gasket, the whole adjustment is difficult and time-consuming, so it is necessary to reduce the test piece and dynamometer as much as possible Adjustment of concentricity between. [0003] However, in the prior art, in order to facilitate the installation of the test piece, the mounting edge of the casing of the test piece and the mounting edge of the volute are directly connected by bolts, and a large gap is designed between ...
