Bearing showed late failure characteristics to a serious failure (generally bearing damage, such as axle, burns, sand frame Spallation raceway the beads wear, etc.) time it tends to be more than a week, the greater the capacity of equipment, the faster the speed, the The shorter the interval. Therefore, bearing in real deep groove ball bearing fault diagnosis, once found late failure characteristics, should be decisive judgment defective deep groove ball bearings, arranged as soon as possible overhaul.
Bearing manufacture popular through forging, heat renew, turning, grinding and assembly multi-channel processing. Reasonable process, advanced, stability can also affect the life of the bearing. Hot renew, and grinding processes affect the bearing quality, often has a more direct relationship with the failure of the bearing. The surface metamorphosis layer of deep groove ball bearings Studies have shown that in recent years, the close ties of the grinding process and the bearing surface quality.
Exercise time, vibration and noise to maintain a certain level, single spectrum appears only one, second harmonic. Very rare triple-frequency spectrum above, very stable state of deep groove ball bearings, into a stable period. Continue into use late run, bearing vibration and noise begins to increase, sometimes a different tone, but the change of vibration increases more slowly, at this time, bearing kurtosis values start suddenly reaches a certain value. Bearing transaction network experts believe that the deep groove ball bearings that showed initial failure.
Bearing primary obligation to use profiling life, is based on a lot with King, analyze data, and failure style pattern to identify the primary elements that constitute a bearing failure in order to propose improvement measures to delay the decommissioning of the deep groove ball bearings, Avoid deep groove ball bearings angry burst of early failure.
1, back to work before the wheel spindle pump station pressure and whether the grinding head static pressure in the standard range.
Equipment downtime, we must first stopped grinding motor until the grinding wheel came to a complete stop, and then turn off the pump station, otherwise easy to damage the grinding head.
3, # 2 spindle oil and coarse and fine filter should be replaced after one year of normal use.
4, the normal use of the pump station to add oil, 3-layer silk cloth filter must participate.
5, for the pumping station on any parts, be sure relieved the high pressure oil inlet hose fittings, the change in finished parts, oil self the loop 15-20 minutes in front of the inlet pipe connected to the grinding head, thus ensuring The grinding head spindle oil is super clean spindle oil through the fine filter. To do so to be able to extend the use of hybrid spindle life.
Spindle pulley grinding wheel handling must stop the state of the pumping station work. That the spindle is stopped under the state of floating in the static pressure oil. So that does not damage the spindle and hydrodynamic bearings.
