The following are some of the noise characteristics and associated countermeasures presented by the motor bearings; here the bearing associates give us a detailed analysis as follows: /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
1. Foreign matter sound set: After the motor is installed, noise is found when the noise is viewed.
Characteristics: The sound of "啪哩啪哩..." is announced intermittently.
Reason: Foreign matter enters the inside of the bearing.
Countermeasures: Improve the cleanliness of the installation line, rotor and bearings.
2, adhere to the sound of the scene: after the motor is installed; when the noise is seen, there is noise.
Characteristics: The sound of "å½å“©å½å“©..." is announced consecutively or intermittently.
Reason: The noise caused by the conflict between the adherer and the steel ball.
Countermeasure: Select the stick grease that adheres to the sound of the instrument.
3, the scar sound (friction wear) set: the motor is transported to the air-conditioning plant for noise viewing to find noise.
Features: The sound of "咔啦......" was announced one after another.
Reason: Because of the fluctuation of the oscillation during transportation; the friction between the steel ball and the tumbling of the bearing causes the sound.
Countermeasures: Improve packaging and transportation methods; use anti-friction wear grease; to improve the pass rate.
4, scar sound (Brinell indentation) set: after the motor is installed; when the noise is checked; found noise.
Characteristics: The sound of "咔啦啦......" was announced one after another.
Cause: When the shaft is pressed into the shaft collar or bearing chamber; Brinell indentation is generated inside the bearing.
Countermeasures: Select the bearing depicted by the indentation; to improve the installation qualification rate; "NSK" anti-indentation depiction.
