one、The clearance clearance of imported bearings should be appropriate，If it is too large, it will cause a shock，If it is too small, the lubrication effect is not very ideal，Severe cases may result in burning of tiles。So the clearance must be appropriate。 two、The journal quality of imported bearings and the geometry of stainless steel bearings must be guaranteed，It must not be shoddy. It is related to whether the machinery can operate normally。
The coupling with the coupling flange is a rigid coupling，The two semi-couplings with flanges are connected to the two axes respectively with ordinary flat keys，Then bolt the two half couplings together，To transmit motion and torque。
In construction machinery vehicles，The usefulness of the Bonner sensor is clear，It effectively monitors the working state of the whole machine and components，Different functions of the Bonner sensor will have their own matters to pay attention to，Thats something you have to keep in mind。
Everybody knows，Now more and more people are using bearings，It also represents its increasing importance in our lives。To choose the right oneTRbearing，A variety of key points need to be investigated。therefore，Today, Feng Yes official website will carry out a simple analysis for you。
Siemens inverter is a power control device that uses the on-off action of power semiconductor devices to convert the power frequency power supply to another frequency,It can realize the soft start of AC induction motor、Variable frequency speed regulation、Improve running accuracy、Variable power factor、overcurrent/overvoltage/Overload protection and other functions。
Harbin Bearing Group Company is a Chinese bearingOne of the three major production bases of the industry，Now owns total assets36.7Hundred million yuan，The main production equipment is about4600Complementary station，Annual production capacity8000More than 10,000 sets。Can produce nine types、Various accuracy levels6000More sizes and varieties of bearings。Mainly used in automobiles、Agricultural machinery、Rolling stock、Motor apparatus、Construction machinery、Machine tool、Light textile、metallurgy、Mining machinery、Petrochemical industry、aerospace、National defense military industry and other industries and enterprises supporting services。Products are sold to domestic provinces、The city、municipality，Also exported to Europe and America、Some countries and regions in Southeast Asia。 Aligning roller bearings can withstand large radial loads，At the same time, it can also withstand certain axial loads。This kind of bearing outer ring raceway is spherical shape，Therefore, it has aligning performance，When the shaft is bent
Should pay attention to，type（4）And form（2）No essential change，Notwithstanding form（3）Is the formula，But it only plays the role of parameter transformation，There is no change（1）（、2）Properties of the definition。Hence the speed expression（4）Its just an artificial definition，Not a formula，Naturally can not become the theoretical basis of AC speed regulation，To do otherwise would be to commit a basic logical error。In addition，By expression（2）Determine the connection between the synchronous speed and the mechanical speed，Its man-made，This is taken as the theoretical basis that the mechanical speed can be changed by changing the synchronous speed，Its obviously not scientific。In fact，Synchronous speed and mechanical speed are two kinds of motion with different properties，The former is mechanical and the latter is electromagnetic，There is no direct connection between the two，You cant make simple synthesis。
Working principle and connection of relay A relay is an automatic switching element with isolation function，Widely used in remote control、telemetry、communication、Automatic control、Mechatronics and power electronic equipment，It is one of the important control components。The following Xiaobian will take you to understand the working principle and wiring method of the relay。
In the past, I often heard customers tell me that their Wafangdian seprecision bearings were corroding，What should be done，Today here Xiaobian to summarize some methods of treatment，Let me share with you！
Users who have been using guide rails know that，In useSJSYSBack rail，There will be dirt on the ball，If we dont clean it up，It will be easy to deposit and scale，Especially if there are no enclosed areas。In that way，To ensure the seal and protective belt function，These filth must be cleaned up regularly。
