introduction：Bearings are to electric cars what joints are to us，In the process of electric car driving，Whether the bearing is safe is greatly related to the safety factor when we ride。For electric cars，The greater the power, the higher the safety of the bearing，If there is accidental damage to the bearing or non-standard use during the driving process，It must be repaired in time，Because this is related to the safety of our later riding。 Electric vehicle bearing is an important part of electric vehicle。Its main function is to support the mechanical rotating body，Reduce the friction coefficient during its movement，And ensure its rotation accuracy。 According to the friction properties of the moving components，Bearings can be divided into rolling bearings and plain bearings two categories。Among them, rolling bearings have been standardized、serialization，But compared to plain bearings its radial size，High vibration and noise，The price is also higher。

introduction：Generally speaking，If the bearing is placed under a certain load，Bearings are based on the number of revolutions to determine their life，therefore，In the bearing can bear the range，Initial friction appears on any bearing circle or rolling element，Both have the potential to reduce the working life of bearings however，In the actual work, the bearing life in the good experiment is not the same，The so-called life of work，Refers to the actual life that a bearing can achieve before it is damaged，Which determines the length of this life is mainly the bearing wear and environmental factors，Corrosion phenomenon，Seal damage and other factors。Because the clarity of the production is different，There are great differences between materials，therefore，The service life is different。According to relevant statistics，Long life is four units，As short as one to two，It shows how big the gap is。

introduction：Whether the miniature bearing is installed correctly，It has a direct influence on its life and the accuracy of the main engine。If improperly installed，Bearings not only vibrate，Loud noise，Low accuracy，The temperature rise increases greatly，Theres also the risk of getting stuck and burning out；conversely，well-installed，It not only guarantees accuracy，Life expectancy will also be greatly extended。therefore，After the micro bearing is installed，Must be tested。

introduction：1、High accuracy ABBABall screw is used for ball movement，Suggested low torque，There will be no creeping, such as sliding motion，Can end accurate micro feed。 2、Can end high-speed transmission ABBABall screw because of high motion power、Low fever、So you can end the high-speed feed（movement）。 3、High power Energy saving because there are many balls rolling between the ball screw shaft and the screw nut of the ball screw，So the motion power is high。And assume the drive is the same size The load of，The use of ball screw can use less drive power，Costs can then be reduced，Save energy。

introduction：Since needle roller bearings have a variety of different mounting methods，Naturally, there are different disassembly methods，Some of the more common ones include Tapping method、Hot disassembly、Push-push method and pull out method four methods，The procedure for each disassembly method of needle roller bearings is no identical，How to master them all？ The first thing to look at is the tapping method of needle bearings in general，When removing needle roller bearings by tapping，Percussive force To act on the bearing inner ring，And can not be added to the bearing rolling body on the river retainer。That is to say，This disassembly method is off The key is to find the right point，The position of the pad should be appropriate。
