FAG bearings using noise-related issues arising in the course of settlement

Grease-lubricated bearing limit speed speed limit lower than oil-lubricated bearings, bearings and oil has an impact on speed limit can be achieved. Required attention, for grease lubricated bearings, its speed limit generally is was the FAG bearings use a repeating cycle of oil quality limit speed when the system 80%, but for oil mist lubrication system, the speed limit is generally lower than the same basic lubrication system of higher 50%.
1, scars and moderation approaches
Rolling bearing the rolling surface indentation or if there are cracks, rust, will attack like rivet rivets periodic vibration and noise, their cycles can be fixed but most speed into this corresponding relationship, scars will continue attacks on the channel, scars on the ball disappeared, and included with the unit and this noise smoothing prerequisite and inevitable change.
Such moderation approach to noise: device not a knock when bearings, FAG bearings and shaft Assembly, then avoid bearing when mounted in housings mounted helical; avoid inventory to avoid bearing corrosion and transportation impact vibration use smoothing of high viscosity grease.
2, dust and moderation approaches
Foreign bodies such as dust in the rolling bearing, will attack non-periodic vibration and the so-called dust, vibration and noise of their large and indefinite, and or with or without.
Dust acoustic abstinence approach are: washing for improved bearings, FAG bearings, shafts, before device full bore and match parts tough clean Shen Qing; put foreign objects inside the smooth agent; improve bearing seal; preventing application information pure or plastic stick with embedded foreign body.
3 elements, lubrication causes noise and its countermeasure
Lubricant selection error, lack of lubricant, or onset of aging induration, and can lead to FAG bearing vibration and noise, and the noise are not necessarily rules. On the situation, as long as the appropriate choice of smoothing agents, adjusting its smooth dose, Japan Seiko, extended life and reasonable use of smoothing agent to determine change cycles.
Also FAG bearing cage design and structure of the speed limit, due to the moving body and cage has a sliding contact surface, with the more expensive, the design fair, made of a high quality and low friction material of cages, can move not only separated from the body, but also to maintain Lube film area of sliding contact. But, like cheap cages, cages, usually separate allows the moving body. Therefore, they there are volatile and vexing sliding contact, resulting in a lower speed limit.
