The effective control of grease used for hot rolling bearing noise

Bearing the examination such as the rotation of the sound with a stethoscope, a strong metal noise, such as vision, irregular note that exception. Its reason has poor lubrication, shaft or precision bearing, bearing damage, foreign body intrusion, etc. Of differences in the rolling bearing grease composition is divided sample outline of open to traffic, must constitute the outline is quite is, go should be short, bearing temperature in is running low, and smooth, this is a kind of more fantasy grease, so the lubricating grease into the canal of special priority. In popular conditions, rolling bearing grease filling amount, is always beyond the practice of directly involved in the lubrication, demand full frame and bearing cover of the cavity, and an outline is made in the rolling around in vitro. In the process, because of excess grease resistance, bearing temperature rise quickly. Although most redundant grease at the beginning of the operation is being squeezed out, and squeezed in the raceway attachment grease could still be migration transformation between the rolling element into the race. Most of these in the early stages of the bearing running grease quickly ( Less than a minute) Is being squeezed out of raceway and accumulate in bao followed the bearing grease migration body cycle also, have a small amount of discharge. When the bearing temperature continues to rise, until all redundant grease were discharge, may be called the grease running-in stage, on the basis of bearing structure elements, such as quality, filling grease content in this period of time may last ten minutes, and even a few hours. Method: 1, cause: TIMKEN bearing low accuracy of selection rules accuracy levels of bearing. 2, cause: spindle winding or casing hole different heart way: repair spindle or box. 3, cause: belt tight way: adjust the belt to make elastic properly. 4, cause: smooth bad way: use rules of smooth information and appropriate clean. 5, cause: remove the low quality: remove the quality progress. 6, cause: TIMKEN bearing inner shell run laps: a change in import bearings and coherent worn parts. 7, the axial force is too big: cleaning, adjustment seal mouth ring clearance request 0. 2 to 0. 3 mm, correcting impeller balancing hole diameter and checking the static equilibrium value. 8, imported bearing failure mode: changing the TIMKEN bearings.
