introduction：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；According to the different transmission series can be divided into single stage and multistage reducer；According to the shape of the gear can be divided into cylindrical gear reducer、Bevel gear reducer and cone－Cylindrical gear reducer；According to the arrangement of the transmission form can be divided into expansion type、Shunt type and coaxial reducer。 The following is the commonly used reducer classification： Planetary cycloidal pin wheel deceleration

introduction： (1)The resultant force of the force passes as far as possibleNSKAxis of bearing，This requires the point of application to be uniform, symmetrical and stable，Force is applied through a sphere or parallel to an axis。 (2)The size of the force should be smooth and even，Not to be impacted，This requires the use of oil pressure or tools that can apply smooth tension or pressure，When the hammer had to be used，It should also be cushioned by softer, non-chipping metals such as copper sleeves，Knock as gently as possible。It is best to use a copper rod or copper hammer for hammering。 (3)Avoid applying force through rolling elements，This requires the inner ring to be installed and removed(Shaft ring)Apply force through the inner ring，When installing and removing the outer ring

introduction：Damage state:FAGWhen the bearing is rotated under load，Inner ring、The raceway surface or rolling surface of the outer ring shows a fishscale peeling phenomenon due to rolling fatigue。 reason:Excessive load。Poor installation（nonlinearity）Torque load foreign body intrusion、flooding。Poor lubrication、Improper lubricantFAGImproper bearing clearance。FAGBearing box accuracy is not good，FAGbearing[bearing:bearing，thkbearing，trbearing，NSKbearing，NTNbearing，SKFbearing，NACHIbearing，KOYObearing，HCHbearing，IKObearing]The deflection of the uneven rigid shaft of the box is large and rusty、erosion
