Rotating body inspection device for electrification component

A rotating body inspection apparatus for an electrification component, the rotating body inspection apparatus comprising:

• a main sprocket on which a rotating body is seated and which is shaped as a disk and rotates;
• a sub sprocket shaped as a disk and rotating;
• a connection portion connecting the main sprocket to the sub sprocket;
• a linear conversion portion which is connected to the sub sprocket and which converts a rotational movement into a linear movement,
• wherein a diameter of the sub sprocket is less than a diameter of the main sprocket,
• wherein the linear conversion portion comprises:
• a rotation portion connected to the sub sprocket and rotating by the sub sprocket;
• and
• a linear portion connected to the rotation portion and making a linear reciprocating movement in response to a rotation of the rotation portion, and
• the sub sprocket rotates in response to a rotation of the main sprocket, and the linear portion makes a linear reciprocating movement in response to a rotation of the sub sprocket;
• the rotation body inspection apparatus further comprising an origin sensor configured to measure a position of a first point at which the linear portion is located according to the linear reciprocating movement of the linear portion;
• and
• a position limit sensor configured to measure a position of a second point at which the linear portion is located according to the linear reciprocating movement of the linear portion,
• wherein the origin sensor and the position limit sensor are disposed in a direction parallel to an axial direction in which the linear portion moves, and
• a position of any one or more of the origin sensor and the position limit sensor is changeable according to a rotation angle of the rotating body.
