摘要： Provided is an inspection device for a rotating electric machine, the inspection device including a photographing device, a drive mechanism, a display, and a controller. The photographing device photographs a pattern formed on a surface of a wedge constituting part of an armature. The drive mechanism moves the photographing device with respect to a stator functioning as the armature. The controller detects strain of the wedge by comparing image data of the pattern photographed by the photographing device with reference data of the pattern. In this manner, the inspection device for a rotating electric machine can easily detect the strain of the wedge. Further, the controller estimates loosening of the wedge based on the strain of the wedge, and informs an operator of the rotating electric machine through the display that the loosening of the wedge has occurred.

摘要： An inspection device inspects an inspection target part by being inserted into a gap between an inner circumferential surface of a stator and an outer circumferential surface of a rotor of a rotary electric machine. The inspection device includes: a traveling body which is attached to a base frame and moves the base frame in an axial direction in the gap; a probe which inspects the inspection target part; a radial-movement portion which moves the probe in a radial direction perpendicular to the axial direction and a circumferential direction; and a circumferential-movement portion which moves the probe in the circumferential direction in the base frame.

摘要： A rotary electric machine examination device of the present disclosure includes: first and second base units attached to both ends of rotor retaining rings fixed to both axial end sides of a rotor; a guide wire stretched between the first and second base units; an inspection unit which moves on the stator and includes a housing having both side surfaces restricted by the guide wire, and a sensor unit; and a driving rope which drives the inspection unit in the axial direction. The guide wire is stretched such that the distance between the guide wire and the rotation axis at the positions of the first and second base units is greater than the distance between the guide wire and the rotation axis at the position of the inspection unit.

摘要： An inspection device includes: a base; a linear motion mechanism which performs linear motion; a link mechanism which has a driven link connected to the base, and which extends/contracts by the linear motion performed by the linear motion mechanism; a connection mechanism for connecting between a driving link of the link mechanism and the linear motion mechanism; and a sensor. The connection mechanism has a link connection portion connected to the link mechanism, and a ball nut that moves in conjunction with the linear motion performed by the linear motion mechanism. When a force higher than or equal to a predetermined force is applied to the link mechanism, the link connection portion is separated from the ball nut so as to contract the link mechanism.

摘要： This device includes: an input unit for receiving a shape of an inspection target surface of a wedge exposed from a slot with no force applied to the wedge; a relation storage unit which acquires and stores, as a deformation reaction force relation, a relation between a reaction force of a spring at the inspection target surface of the wedge and deformation distribution from the shape of the inspection target surface of the wedge inputted to the input unit; a measurement unit for measuring measurement deformation distribution of the inspection target surface of the wedge; an estimation unit for estimating an estimation reaction force from the measurement deformation distribution and the deformation reaction force relation; and a judgement unit for judging proper/fault about looseness of the wedge from the estimation reaction force.
