After the installation of Timken bearing, in order to check whether the installation is correct, operation inspection shall be carried out. Timken Plain Bearing Small machinery can be rotated by hand to confirm whether it rotates smoothly. The inspection items include poor operation caused by foreign matters, scars and indentation,
unstable torque caused by poor installation and poor processing of mounting base, excessive torque caused by too small clearance, installation error and sealing friction, etc. If there is no abnormality, the power operation can be started. Large machinery cannot rotate manually, so the power shall be cut off immediately after no-load start,
and the machinery idles. Check whether there is vibration, noise, contact of rotating parts, etc. after confirming that there is no Timken Plain Bearing abnormality, enter the power operation. Power operation, starting from no-load and low speed, slowly increase to the rated operation under the specified conditions.
During the test run, the inspection items are whether there is abnormal sound, the temperature change of plane bearing, the leakage or Timken Plain Bearing discoloration of lubricant, etc. If any abnormality is found, stop the operation immediately, check the machinery, and remove the bearing for inspection if necessary.
The temperature can generally be inferred from the external temperature of the bearing seat. However, it is more accurate to directly measure the temperature of Timken bearing outer ring with oil hole. The bearing temperature rises gradually from the beginning of operation, and the temperature is usually stable after 1 ~ 2 hours.
If the bearing is not installed properly, the temperature will rise sharply, resulting in abnormal high temperature. The reasons are too much lubricant, too small bearing clearance, poor installation, excessive friction of sealing device, etc. In the case of high-speed rotation, the wrong selection of structure and lubrication mode is also the reason.
Even small dust that cannot be seen by the eyes will have a bad impact on Timken bearings. Therefore, Timken Plain Bearing keep the surrounding clean so that the dust will not invade the plane bearing.
2. Use the bearing carefully and give Timken bearing strong impact Timken Plain Bearing during use, which will produce scars and indentation, which will become the cause of the accident. In serious cases, it will crack and fracture, so we must pay attention to it.
3. Use proper operation tools
Avoid replacing with existing tools, Timken Plain Bearing and appropriate tools must be used.
4. Pay attention to the corrosion of plane bearing
When operating the bearing, the sweat on the hand will become the cause of rust. Pay attention to operate with clean hands and try to wear gloves.
Understanding the use method of Timken bearing will get twice the Timken Plain Bearing result with half the effort, which is very important.
When the mechanical parts near the bearing have been lubricated with oil or need to be dissipated by lubricating oil, the bearing shall be lubricated with oil. When the bearing is under heavy load or high speed, or there is external heat transfer, there may be heat dissipation requirements.
The micro lubrication method, such as oil drop lubrication, oil mist Timken Plain Bearing lubrication or oil-gas lubrication, can ensure that the oil mixing loss and bearing friction are very small.
When air is used as a carrier, it can directly supply oil and make the air flow contribute to sealing.
Where the rotating speed of plane bearing is very high and good cooling is required, a large amount of lubricating oil can be sprayed directly onto all contact surfaces.
