Advice: the pressure of cooling water shall be acuity, bearing, believes everyone not unfamiliar, we should be familiar with the commonly used rolling bearing, it is the important parts of modern machinery and equipment.
This ingenious structure make it with automatic self-aligning properties, and therefore susceptible to shaft and bearing box seat Angle error or the influence of shaft bending, suitable for installation error or shaft deflection caused by the Angle error of the occasion.
But will get a clearance range (after
Probably, in addition, we should balance adjustment method of improvement including exciter generator of the whole shafting vibration calculation method of inspection.
Acceleration type test method of the bearing vibration measuring instrument installation method as shown in the specified test conditions, the bearing running period of time to get the stable bearing vibration state, corresponding to each measurement location in some state of bearing vibration value.
Crack of bearing inner ring and outer ring, bearing by external shock load or due to bad lubrication, lead to race beyond mechanical design standards, to produce pit, bearing corrosion, is not recommended with heat seal and bearing dust cover to ℃ above (
Shall ensure that the temperature does not exceed the seals and the allowed temperature grease)
。
In bearing before installation, if need to add grease in the bearing, oil must be cleaned, right amount, usually users should put the bearing into the heated to ° - in mineral oil
° immediately when loaded on the spindle.
When replace the bearing shell to remove the plate can reduce the height of the jack up the car, wood dust shield sealing is poor, often shaft oil leakage, in recent years gradually convert rubber dust shield.
Mechanical spindle common faults of maintenance treatment: fever, rotating precision degradation failure phenomenon: the low machining precision of workpiece hole, cylindricity is very poor, spindle fever quickly, processing noise is very large.
The determination of the bearing clearance: top clearance can be determined according to experience, also be determined by calculation, the bearing clearance measurement: check the bearing radial clearance, a measuring method and the feeler method with lead.
Pay attention to much oil wedge tilting type bearing, group segment thickness error should be less than that between bearing has good starting performance, high reliability, convenient maintenance, many a bit is widely used and mechanical devices.
For maintenance should be removed when the wheel, use a screwdriver to pry the dust cover, remove the shaft with forceps spare nuts the lock on the split pin, hand brake drum rotation, with the wheel fixed nut wrench knob, when there is obvious hysteresis and drag friction bearing place, slowly unscrew nuts, immediately until the alignment of a split pin hole, insert a new cotter pin (
It is worth noting: in any case are nut can not be reversed back/circle, otherwise it will cause the wheel hub bearing kuang, leading to early wear)
。
In addition to grinding machining, casting and heat treatment heating caused by the surface decarburized layer, if again later processing has not been completely removed, residual on the workpiece surface will cause surface softening metamorphism, contribute to FAG bearing early failure.
