Description

TECHNICAL FIELD

[0001] The utility model relates to motor rotor auxiliary detection device field especially relates to a motor rotor dynamic balancing machine auxiliary detection device. BACKGROUND

[0002] The motor is a system that can realize the conversion between mechanical and electrical energy, and its structure is composed of a stator, a rotor, bearings and other electrical systems and mechanical systems. The rotor is an important part of the motor and generator, and its function is to provide a rotating magnetic field.

[0003] During the operation of the wind turbine, the entire rotor is in a high-speed rotating state. The flange plate is a part that connects the rotor support and the shaft system or the transmission shaft of the gear box, the brake disc is used to provide braking, and the carbon brush ring is used to lead out the shaft current. It is particularly important to ensure that the performance of the related components of the rotor meets the requirements.

[0004] The vertical state flatness of the brake disc is detected by using the base, support disc, fixing frame, detection frame, sliding base and micrometer and other components in cooperation. According to the design of the fixing frame with a support rod rotatably installed on it, the top end of the support rod is welded with a support disc, the brake disc is placed on the support disc and is tightly positioned by the positioning disc. Then, the position of the detection frame is adjusted to press the needle of the micrometer on the brake disc. By rotating the support rod, the brake disc is rotated, and the flatness of the brake disc is detected by the micrometer. However, this method is used to detect the flatness of the brake disc, flange plate and other loose parts. The detection range is limited, it cannot confirm whether new problems will occur during assembly, it cannot confirm whether the flange plate and other components are in normal state during high-speed operation of the rotor, and the detection effect is not good. When the rotor rotates at high speed, the flatness of the brake disc and flange plate cannot be detected.

[0005] Therefore, it is particularly important to design a motor rotor dynamic balancing machine auxiliary detection device that can detect the flatness of the flange plate, grounding ring, shaft and other rotors at different speeds of the high-precision smooth metal surface, hidden defects, shape size, roughness, fine cracks, slight convexity or concave of the arc surface, etc. during the production and circulation of the rotor (such as suitable for large permanent magnet rotor).
