NTNbearing[NTNbearing:NTN A variety of bearing products，therefore 0.01 It is produced by high-precision machining and testing technology in micrometers，From the requirements of both high performance and low cost of ordinary household appliances，Aerospace rockets that can still perform their bearing functions normally in harsh working environments are required， NTN Bearings in all walks of life、Lay the foundation for the development of machinery for various purposes]It is one of the important components of construction machinery，Poor installation will affect its use effect，It even causes the failure of construction machinery and equipment。

There are two most common ways to replace bearings：One is to use acetylene oxygen vapor pairsNTNBearing direct heating;The other is to use oil immersion heating for small bearings，Reach thermal expansion，Enlarge bearing bore，For assembly。These methods have been widely used in long-term equipment maintenance，Basically satisfied and solved the problem of bearing assembly in equipment maintenance。The axial equivalent dynamic load is

NTNThrust ball 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 temperature of，Generally byNTNbearing[NTNbearing:NTN A variety of bearing products，therefore 0.01 It is produced by high-precision machining and testing technology in micrometers，From the requirements of both high performance and low cost of ordinary household appliances，Aerospace rockets that can still perform their bearing functions normally in harsh working environments are required， NTN Bearings in all walks of life、Lay the foundation for the development of machinery for various purposes]The temperature outside can be inferred，If the oil hole can be measured directlyNTNThrust ball bearing outer ring temperature，Is more appropriate。
Diaphragm coupling function： 1、Used to connect shafts to shafts，To transmit motion and torque； 2、Compensates for the relative displacement of the two connected axes；Manufacturing machine installation error、Amorphosis、Temperature variations do not guarantee strict alignment。 3、Can be used as a safety device； 4、Vibration absorption、buffer。 Diaphragm coupling A part used to join two shafts and transmit torque，Also sometimes double as overload safety protection
Diaphragm coupling installation is a very precise work，First of all, before installation, we should first look at whether the mechanical two axes are concentric，Check the surface of both shafts for bruises and wrapping paper，Carefully check the inner holes of the two half couplings for debris，If there is, it should be cleaned up，Otherwise, it will affect the service life of the coupling，Bruising should be smoothed out with a fine file，So lets measure it，Mechanical coupling inside both ends...
NTNImported bearing[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。]The service life depends on the quality of the product itself，There are other important factors。 one、 Bearing selection stage，There are many factors to consider（case：load，hardness，Operating environment），Well.NTNImported bearing[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。]The design will first enable the bearing to reach its maximum life value。
1 First adjust to make sure that the left and right summation and the up and down summation reading is basically the same,This ensures that the motor or reducer does not skew； 2 Ensure that the dial indicator is located at a fixed reference end,Adjust the left and right position of the reducer according to the left and right reading,Reach the left and right dimensions within the allowable error range； 3 Adjust left...
The cross shaft universal coupling is a common coupling。By using its structural characteristics, it can make continuous rotation of two axes with equal angular speed which are not in the same axis or the axis Angle is larger or the axial movement is larger，And reliably transfer torque and motion。
