Bearing fault identification and main form
Three ways to identify bearing failures
Bearings are precision parts on mechanical equipment，You want the factory how the factory increases productivity，first of all， The performance of the mechanical equipment must be the best，One of the biggest relationships between the mechanical equipment bearing performance。therefore， When the plant is produced and processed，Ensure good inspections on bearings in mechanical equipment。For security reasons，Three ways to identify shared bearing failures：I hope everyone can help。
1。 Speech Recognition
Voice recognition requires rich experience。It must be fully trained，Can distinguish bearing sound and non-bearing sound。to this end，It should be tried to have a special person to carry out this work.。Use listeners or listening sticks installed on the housing，You can clearly listening to the sound of the bearing。
2。 Recognition by operating temperature
This method is a comparison method，Only occasions that do not change the operation status。to this end，Must continue to recover the temperature continuously。Temperature at the time of failure will not only rise，Improving changes will also occur。Use this method with the speech recognition method is suitable。
3。 Status recognition by lubricant
Sampling and analysis of 易彤破壁机漏水维修 lubricants，Through its degree of pollution，Determine if foreign matter or metal powder is mixed。This method is especially effective for observing the approaching or too large bearing。
Main form of rolling bearing failure
1。Fatigue
Rolling bearing，The surface of the outer roller and the surface of the rolling element are subjected to load and relatively rolling，Due to alternating load，the first， A certain depth below the surface（Maximum shear stress）Form crack，Then extend to the contact surface，Surface layer flakes，Finally develop into large flaps，This phenomenon is fatigue stripping。Fatigue explosion will increase impact load， Running vibration and noise。
2。wear
Due to dust and foreign matter，The 易彤破壁机不转 relative movement of the raceway and the rolling body causes surface wear，Poor lubrication also increases wear，Due to wear， Bearing gap increase，Surface roughness increase，Reduce the work accuracy of the bearing，as a result， The accuracy of the machine movement will also be lowered，Vibration and noise will also increase。For precision mechanical bearings，usually，Wear amount limits the life of the bearing。
3。Plastic deformation
When the bearing is inherited from too large impact load or static load，Or additional load due to thermal deformation，otherwise，High hardness foreign matter invaded，Dedication or scratches。This will cause a bearing to generate serious vibration and noise during operation.。Once there is an indentation，The impact load caused by the indentation will further cause stripping of the nearby surface。
4。rust
Rust is one of the most serious problems with rolling bearings。High-precision bearings may result in low accuracy due to surface corrosion and cannot continue to work。Water directly penetrate， Acid or alkaline substances cause bearing corrosion。When the bearing stops working，Bearing temperature dropped to dew point，The moisture in the air condenses the water droplets attached to the surface of the bearing also cause corrosion.。In addition，When there is current through the bearing，Current may flow through the contact between the roller and the rolling element，Very thin oil film can cause electric spark to generate electrical corrosion，A dishilant unevenness is formed on the surface。
5，fracture
Load is too large to cause bearing parts rupture。Grinding Heat treatment and assembly can result in residual stress，Excessive thermal stress during work will also cause the bearing parts to break。In addition，Improper assembly method and assembly process，This may also cause the bearing ring rib and roller chamfer to fall。
6。glued
Working with poor lubrication High-speed overloading due to friction and thermal bearing parts can reach high temperature in a short period of time，Cause surface burns and bonding。The so-called gluing means a phenomenon that the metal attached to the surface on another part is attached to the surface.。
7。Damaged cage
Incorrect assembly or use may cause kept deformation，Increase the friction between it and the rolling element，Even if some scrolling elements are stuck，Can't scroll，It may also cause friction between the cage and the inner ring and outer ring.。This damage will further exacerbate vibration， Noise and heat。Bearing damage。
