1.High speedTIMKENbearing[bearing:bearing（“Bearing”，Japanese person“Axial receptor”）It is a part that holds and reduces the friction coefficient of load during mechanical transmission。Can also be said，When other parts move relative to each other on the shaft，A device used to reduce the coefficient of friction during power transmission and to keep the center of the shaft fixed。]The fit and clearance due to the machine toolTIMKENbearing[bearing:bearing（“Bearing”，Japanese person“Axial receptor”）It is used to fix and reduce the load friction system during mechanical transmission
High speed spindle system and its drivers High speed spindle system of CNC gold cutting machine，As the name suggests it has a high turning speed，But there are no hard and fast boundaries。As a representative of high-speed cutting machine tool machining center and CNC milling machine，Generally refers to the highest speed≥10,000r/minSpindle system，And correspondingly has a high Angle plus(Reduction of)speed，To achieve the instantaneous speed of the spindle and start stop。In order to adapt to the manufacturing industry to the higher and higher machining accuracy requirements of machine tools，The high speed cutting spindle should also have higher rotation accuracy，Generally, the radial runout of the spindle is required to be less than1or2μm，Axial movement is less than1μm。In addition
In actual production,We often need bearings[bearing:bearing（“Bearing”，Japanese person“Axial receptor”）It is a part that holds and reduces the friction coefficient of load during mechanical transmission。Can also be said，When other parts move relative to each other on the shaft，A device used to reduce the coefficient of friction during power transmission and to keep the center of the shaft fixed。]The rotation flexibility was tested,rightINAbearing[bearing:bearing（“Bearing”，Japanese person“Axial receptor”）It is the part that fixes and reduces the friction coefficient of load in the process of mechanical transmission
Some people only pay attention to the installation and use of the reducer，And the lubrication of the reducer is left behind，In fact, lubrication is also very important and can not be ignored。The following describes how to lubricate the reducer。 1、Under normal conditions the reducer can be lubricated using an oil pool，Keep the oil level in the middle of the oil window，If it is in the case of poor working conditions，Cyclic lubrication can be used if the ambient temperature is high。 2、When refueling, you can unscrew the ventilation cap on the upper part of the frame to directly refueling。It is also necessary to put the frame when the oil is discharged
Under normal circumstances，As the worlds top bearing[bearing:bearing（“Bearing”，Japanese person“Axial receptor”）It is a part that holds and reduces the friction coefficient of load during mechanical transmission。Can also be said，When other parts move relative to each other on the shaft，A device used to reduce the coefficient of friction during power transmission and to keep the center of the shaft fixed。]theKOYOBearing will not occur exciting vibration，But if an excitation occurs，Then we must have a good look at the situation，Now lets explain the truth of excitation。 1.When our wuxi bearing[bearing:bearing（
