1, the vibration of the rod end
The rod end bearing vibration is very sensitive to the rod end damage, such as peeling, creasing, rust, cracks, wear and tear and will be reflected in the rod end bearing vibration measurement, and so, by using a special rod end bearing vibration measurement (frequency analyzer) measures the size of the vibration frequency can not infer the exception of the specific situation. The measured values ??due to different conditions of use rod ends or sensor installation location, determine the criteria for judging prior to the measured value of each machine.
2, the temperature of the rod end
Rod end bearing temperature, generally rod ends outside the room temperature can be inferred, if the hole can directly measure the rod end bearing outer ring temperature, suitable even more bits.
Typically, the temperature of the rod end with the rod end bearing running slowly began to rise after 1-2 hours to reach steady state. The normal temperature of the rod end machine heat capacity, heat dissipation, speed and load. Lubrication, suitable mounting part, the rod end bearing temperature are abrupt rise, there will be unusually high temperatures, then have to stop running, take the necessary precautions.
Using the thermal sensor can always monitor the operating temperature of the rod end, and alarm or stop automatically when the temperature exceeds the specified value to prevent the burning shaft accident occurred.
High temperature is often said that the rod ends in the unusual circumstances. The high temperature is also harmful to the rod end of the lubricant. Sometimes the rod end overheating can be attributed to the rod end bearings lubricant.
The rod ends even move more than 125 ℃ temperature long-term reduce the life of the rod end. Caused by high temperature rod ends for reasons including: lack of lubrication or excessive lubrication, lubricants. Containing impurities, the load is too large, rod end damage ring, lack of space, and oil seals produce high friction.
Continuous monitoring of the rod end bearing temperature is necessary, whether it is the measuring rod end itself, or other important parts. If you are under the same operating conditions, any temperature change has failed.
Regular measurements of the rod end bearing temperature by means of thermometers, the skf digital thermometer, for example, accurately measuring rod end joint bearing temperature according to the ° C or Fahrenheit temperature of unit.
The importance of the rod end, which means that when it is damaged, can cause equipment downtime, so this type of rod end should preferably be the installation of temperature probes.
Under normal circumstances, the rod end will be just lubrication or re-lubrication after a natural rise in temperature and continue for one or two days.
