introduction：Cause of rolling noise of roller bearing，The reason of roller bearing rolling noise is the raceway sound of roller bearing and its control method Raceway sound is when the bearing is running，A smooth continuous sound made by the moving body moving on the raceway surface，It is the unique basic sound that all dynamic bearings will occur。

introduction：?Roller bearing maintenance Thin oil lubrication：The advantage is that the internal friction coefficient is small，So it takes less energy to overcome friction，Thin oil flows well，Easy access to the friction surface of each lubrication point，It has good cooling effect，And can adhere to the friction surface of impurities and metal particles due to grinding away。The disadvantage is that the oil film cannot withstand large unit pressure，High requirements for sealing。High speed presses generally use large flow thin oil lubrication，Can take away the heat generated by each friction pair。 Bearing mounting method 1）Wash the bearing with kerosene，Press into bearing seat，Fill the roller of the bearing outer ring with Shell 3 lithium grease to two-thirds full，Apply evenly with clean hands，mountntnBearing gland，Tighten the bearing gland with a tightening bolt coated with bolt-locking adhesive； 2）The bearings are cylindrical roller bearings with separable inner and outer sleeves，The bearing inner shall be fitted to the sha

introduction：Aligning ball bearings mainly bear the load from the radial，In addition, small axial loads can also be borne to a certain extent。shaft（shell）The axial displacement should be controlled within the clearance limit，It has a special performance of automatic aligning，in-turn、It can also work normally in the working environment with little relative tilt of the periphery，It is also suitable for parts where the coaxiality of the support seat holes cannot be strictly guaranteed。 The ability of aligning ball bearing to bear radial load is large，And can also withstand a certain degree of axial load。When the bearing is tilted or bent by the force, the relative inclination of the inner ring center line and the outer ring center line does not exceed1°～2.5°when，The bearings still work。 The shape of the outer ring raceway is spherical，It has automatic centering，It can compensate the error generated by different concentricity and shaft deflection，But therein、The relative inclination of the outer ring cannot be e
