（1）Installation aspect：If mounted on the axle，Make sure its in place and parallel to the left and right，becauseTIMKENbearing[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 outer ring is fixed to the chassis，And the inner ring is active，So pay attention to the wheel can not be pressed
Double row angular contact ball bearings are lubricated[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。]To the effect of dust and rust。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 phase each other on the shaft
http://www.hljjsj.cn As everyone knows，A machine usually consists of three basic parts:Immediate engine、Reducer device and working mechanism。In addition，According to the needs of the machine，Possibly incline control and lubrication、Lighting and other auxiliary systems。The mechanical reducer device refers to the intermediate device that transmits the mechanical energy generated by the power machine to the working mechanism in a mechanical way。The mechanical reducer device can respectively play the following roles: 1)Change the output speed of the engine(retard、Speed up or speed change)，Fit to work
1、The composition of CNC machine tools CNC machine tool is mainly composed of machine tool body and computer numerical control system，As shown in the figure5As indicated。 （1）、Machine tool body Machine tool body is the main body of CNC machine tool，Base piece（bedlike、base）And moving parts（worktable、headstock）Make up。It is not only to achieve various movements controlled by numerical control devices，But also to withstand a variety of forces, including cutting forces，Therefore, the machine tool body must be guaranteed to have good geometric accuracy、Sufficient stiffness、Small thermal deformation、Low friction resistance，In order to effectively ensure the CNC machine tool
one,Installation method FAGSelf-aligning roller 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 installation should be based on the 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 phase each other on the shaft
Worm gear reducer is a mechanical transmission device to reduce the motor（motor）Rotational speed，The inverter is by changing the alternating current frequency to reach the motor（motor）The purpose of speed regulation。When the motor speed is reduced by frequency converter，Can achieve the purpose of energy saving。Domestic more famous inverter manufacturers have three crystal、Inwitten and so on。 The reducer is a relatively precise machine，The purpose of using it is to reduce the speed，Increase torque。There are many kinds of it，Different models，Different kinds have different uses。There are many kinds of retarders，According to the transmission type can be divided into gear reducer、Worm reducer and planetary gear reducer
1、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。]The quality of the parts must meet the corresponding national standards、Industry standard requirements，Drawings with marks shall be subject to drawing standards。 2、bearing[bearing:bearing（“Bearing”，Japanese person“Axial receptor”）It is used to fix and reduce the load friction system during mechanical transmission
Bearing in process[Imported bearing:Simply put, the import bearing agent refers to the sale of an imported bearing brand。The main brands of imported bearings arenskbearing，ikobearing，fagbearing，Of good quality，Of course, the price is not cheap。]pre-destruction，It provides users with sufficient discovery time，Dont ignore the friction，It slows down the speed of the ride，It takes more energy and less speed over long distances。If the roughness of the surface is subtle，If the lubricating oil film has the appropriate thickness，The probability of surface stress formation is quite low，That is why the appropriate choice is appropriate
first：Flat 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。]Abnormal load on cage Inadequate installation、tilt、Too much interference can easily reduce the clearance，Increase friction and generate heat，Surface softening，Premature abnormal flaking，As the spalling expands，Exfoliate foreign matter into cage hole，Causing the cage to block operation and produce
chongcai blanking blanking A stamping process that separates parts or blanks of desired shape and size from sheet metal。Blanking is to use the cutting edge of the die to produce shear deformation and separation of the plate along a certain contour line。Blanking accounts for the largest proportion in stamping production。In the blanking process，Except for cutting the metal near the contour line，The sheet material itself does not produce plastic deformation，Therefore, the parts machined by flat stamping are still a flat shape。 Blanking can be divided into cutting、blanking、punching、sever、Incision and incision, etc。①Shearing is the cutting of large plates into strips。②Blanking is along a seal
