TIMKEN bearing grease on the stability of inspection and maintenance points - bearing knowledge

Bearing temperature, average according to the external temperature of the bearing. But using the oil hole directly measuring the temperature of the TIMKEN bearing outer ring more accurate. The bearing temperature, starting operation gradually increases, usually 1 ~ 2 hours after the temperature stability. If the bearing installation, the temperature will rise sharply, abnormal high temperature. The reason such as lubricant, bearing clearance is too small, too much bad installation, excessive friction sealing device, etc. High-speed rotation, the choice of the ways of bearing structure, the lubrication error and so on is also the reason. 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. Differences in TIMKEN 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, TIMKEN bearing grease filling amount, in always goes beyond the practice demand directly involved in the lubrication, 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. Bearing (degrees still continues to rise at this moment, until all redundant grease were discharge, may be called the grease running-in stage, according to the structure of the bearing grease, filling quantity elements such as quality, this paragraph of time may last ten minutes, and even a few hours. At the time of anti friction bearing filling grease, may not need to use the theory of high pressure, unless very careful to use. High pressure can damage the bearing, waste grease, excessive grease caused by high temperature dangerous and surrounding the TIMKEN bearing invisible environment. In most applications, the ball or roller bearing lubrication, if grease level accounted for a third to a half of bearing capacity. Beyond the amount of usually will be sealed shell discharge and waste. All TIMKEN bearing friction resistance of the bearing basically contains two hardened steel rings, multiple hardening of ball or roller, roller and a separation or roller or maintaining aircraft separation. These types are in use is divided into many types. Some types, such as bearings, needle column may not have the internal ring, roller directly on hardening axis movement.
