introduction：（one）When installing the belt，The strap should only be put on after reducing the distance between the two wheels，Do not pry，Avoid belt damage and reduce service life。 （two）When installing the pulley，The axes of the two wheels must be parallel；The center line of the wheel groove must also be aligned，Otherwise, it will cause premature wear on one side of the triangle belt working surface。 （three）Tape selection time，There must be no mistake about the size and nominal length，In order to ensure that the triangle belt section rediscusses the correct position in the slot。 （four）In the same drive, there are more roots of the triangle belt，You cant use old and new，Bands of varying lengths，Avoid load distribution

introduction： 1 Pickling bubble Pickling bubbles are caused by the acid interacting with exposed metal，Caused by the formation of hydrogen。Hydrogen atoms react chemically with metals and acids，Some hydrogen was formed，It permeates the crystalline lattice of the metal，And make it deform，The deformation diffuses hydrogen further into the metal，Some of these hydrogen atoms pass through the metal and are molecularized，Escape from the acid，Partial molecularization of hydrogen atoms occurs when the lattice is deformed“microvacancy”On the border，Or metal inclusion and porosity，The pressure of hydrogen in air can reach hundreds of atmospheres，It creates internal stresses in the metal that cause hydrogen embrittlement。

introduction： 1. FAGBearing accuracy improvement method FAGAfter the bearing is installed in the main machine，As measuredFAGRadial runout of the bearing spindle，It can be found that the measured value of each turn has a certain change；When measuring continuously，It can be found that after a certain number of revolutions，This change is approximately repeated。The index to measure the degree of this change is the rotation accuracy of the cycle，The variation is approximately repeated by the number of revolutions required to represent the accuracy of the cycle rotation“quasi-periodic”，The amplitude of the magnitude change in the quasi-period is large，That is, the cycle rotation accuracy is poor。
