Household appliance bearings, bearings to withstand the loads are small, FAG bearing life is very long. Bearing operation after a period of time, will have an increased abrasion, vibration, noise, deterioration of grease, and so on. Due to stringent requirements for appliances bearing noise when when the bearing noise is outside the allowed range, that the SKF bearing has can′t continue to use. Total time in bearing with low noise operation called a bearing noise life.
Ball bearing of noise than roll child bearing of low, relative sliding less of FAG bearing of (friction) noise than relative sliding more of bearing low; 2) using entity keep frame SKF bearing of noise relative to than using stamping keep frame of bearing low; using plastic keep frame bearing of noise than using above two species keep frame of bearing are low; ball number more of, outer ring thick of, noise also smaller, 3) precision high of bearing, especially by with scroll body precision more high of bearing, its noise to than low precision bearing of noise relative smaller, 4 ) Of bearing noise bearing noise is relatively small.
FAG bearings for complex manufacturing process has to go through many processes before you can get the finished product, forging, heat treatment, machining and grinding process of technological capability and quality will affect the life of the bearing and application, in particular heat treatment and grinding, but also many direct causes of bearing failure and require enterprises attach great importance to.
Large machinery cannot be manually rotated, so no load starting cut off immediately after power, machine idling, check for vibrations, noise, is there contact rotating parts, and so on, after you determine that no exception, running into the engine.
FAG bearing temperature, usually according to the external temperature of the housing speculation. But the temperature measurement of bearing outer ring with holes directly is more accurate. Bearing temperature, work began to rise, usually temperature-stable after 1-2 hours. If adverse bearing installation, temperature rises dramatically, resulting in abnormal high temperature. Reasons such as excessive lubrication, the bearing clearance is too small, poor installation, excessive seal friction. High speed rotation, bearings, lubrication and a cause, such as selecting the wrong way.
