    A prediction, prevention, ways to early failure of the needle bearing
Needle roller bearings in machinery and equipment service life is an important indicator, the status of work to understand and gr asp the needle bearing, prediction, prevention of needle roller bearings early failure is necessary. Usually have the following main ways.
(1) the use of advanced technology to improve life and reliability of the needle bearing. Including the structural optimization of design, process reform, selected and refined materials, the lubrication of high-efficiency noble, fine assembly and installation.slewing bearing suppliers
(2) to strengthen the quality inspection and supervision of the needle roller bearing, ensure that the needle roller bearing product quality to meet the relevant standards or design requirements.
(3) strengthening the monitoring and diagnosis on the state of the needle bearing, early detection of abnormalities, using precautions to prevent sudden accidents may result in significant losses.
Fault diagnosis detection system
The needle bearing fault d iagnosis technology is linked with the precision of the test system and monitoring tools. The practical application of more sophisticated detection system are the following.
(1) side of needle bearing pulse oscillator devices
Needle roller bearing fatigue wear (or fatigue spalling), resulting in the vibration receiver mechanical pulse signal is converted to electrical signals and zoom. Outside the normal range when the number of pulses to achieve sudden, immediate alarm, needle roller bearings to stop using.china bearing
(2) needle bearing temperature alarm device
Poor lubrication, needle bearing surface wear or fatigue will cause the surface heat, heat to a certain limit of temperature, both the line alarm, needle roller bearings to stop running.
(3) periodic testing run in needle roller bearing state, the detection or monitoring of existing defects extremel y development trends.
(4) iron spectrum of diagnostic method
Timed to extract samples of work needle bearing grease, iron spectrometer detection in which the number of abrasive size and shape characteristics, can be found in the extent of fatigue and wear, and found that the sign of the needle bearing failure.slewing bearing manufacturers
