Portable motor rotor detector

Abstract

The invention discloses a portable motor rotor detector. The detector is characterized by comprising an operating console, a detection ring, a cylinder, a pressing block and springs, a fixed plate is arranged on the operating console, a cylinder is fixedly mounted on the fixed plate and is provided with a connecting rod, the connecting rod is connected to the pressing block, a block is arranged in the fixed plate, the springs are arranged in the block, the detection ring is fixedly mounted on the block via a buffer plate, and the detection ring is provided with a limiting rod. The portable motor rotor detector has the advantages that rollers and brake discs are mounted under the operating console so that the detector is convenient to move and transfer, the brake discs can provided a static work table top for the detector, the detection effect is not influenced, the structure is simple, the cylinder cooperates with the pressing block to press a rotor into the detection ring and provide convenience for rotor detection, the concentricity and verticality of the rotor are further improved, and the rotor quality is ensured.

Description

technical field [0001] The invention relates to the technical field of rotor detection, in particular to a portable motor rotor detection device. Background technique [0002] According to the ISO standard, a rotating body supported by bearings is called a rotor. Rotors are mostly the main rotating parts in power machinery and working machinery. Typical rotors include turbomachinery rotors, motor rotors, various pump rotors, and turbocompressor rotors. When the rotor rotates at certain speeds, it will deform greatly and cause resonance. The speed at which resonance is caused is called the critical speed of the rotor. In engineering, a rotor whose working speed is lower than the first-order critical speed is called a rigid rotor, and a rotor whose working speed is greater than the first-order critical speed is called a flexible rotor. Since the rotor rotates at a high speed, it needs to be balanced. Static balancing is mainly used to balance the inertial force of the disc...

AI Technical Summary

Problems solved by technology

[0003] The motor mainly includes two parts, the rotor and the stator. It is a device for converting mechanical energy and electrical energy or electrical energy and mechanical energy. As a rotating part in the motor, the quality of the rotor directly affects the quality of the motor. The concentricity and verticality between the rotor pieces will affect the quality and performance of the rotor. At present, most of the detection devices for the verticality and concentricity of the rotor have problems such as low work efficiency and inconvenient operation.
