1. Abnormal load: choose the appropriate assembly clearance and preload
2, poor assembly: improve the machining accuracy of the shaft, improve the installation method
3. Insufficient lubricant: supplement or use suitable lubricant
Regular tone
1. Foreign matter causes channel corrosion, indentation, and scratches: cleaning related parts, using clean grease
2, channel spalling: fatigue wear, replace FAG bearings
Irregular sound
1. Intrusion of foreign matter: cleaning related parts, using clean grease
2, the clearance is too large: pay attention to match and choose the right clearance
3, steel ball scars: steel ball fatigue peeling or foreign body card damage, replace FAG bearings
Abnormal temperature rise
1. Too much lubricant: reduce lubricant
2. Insufficient lubricant, or not suitable: increase lubricant or choose suitable lubricant
3. The mating surface creep or sealing device is too large: FAG bearing outer diameter or inner diameter matching surface is corrected, and the sealing form is changed.
The rotary vibration of the shaft is large
1. Peeling: Fatigue peeling off, replacing FAG bearing
2, poor assembly: improve the machining accuracy of the shaft, improve the installation method
3, foreign matter intrusion: cleaning related parts, using clean grease
Lubricant leakage is greatly discolored
1. Too much lubricant: reduce lubricant
2, foreign body invasion: cleaning related parts
Type of anti-friction bearing:
Anti-friction bearings are divided into two main types. They are ball bearings and roller bearings. At the same time, we also know that many different types have evolved according to these basic structures due to the different uses of the manufacturer and the bearing.
Lubrication function:
Anti-friction lubricants have the following main functions
1. Lubricate the sliding contact between the retainer and the rest of the bearing.
2. Lubricate any contacts between the race and the roller that is not actually rolling.
3. Lubricate the sliding contact between the roller and the guide in the roller bearing.
4. Lubricate all the truly rolling contacts in the bearing.
