1.Stainless steel refers to the corrosion resistant steel in the atmosphere and weak corrosive media。Corrosion rate less than0.01mm/annual，Deem to be"Complete corrosion resistance"；Corrosion rate less than0.1mm/annual，Deem to be"Corrosion resistance"the。 2.Corrosion resistant steel refers to steel that can resist corrosion in various strong corrosive media。 Corrosion resistance of various stainless steels 304It is a kind of universal stainless steel，It is widely used in manufacturing requiring good overall performance(Corrosion resistance and formability)Equipment and machinery。 301Stainless steel shows obvious work hardening during deformation，It is used for parts requiring higher strength
China is the first in the world to invent rolling bearings[bearing:bearing，thkbearing，trbearing，NSKbearing，NTNbearing，SKFbearing，NACHIbearing，KOYObearing，HCHbearing，IKObearing]One of the countries China is the first in the world to invent rolling bearings[bearing:bearing，thkbearing，trbearing，NSKbearing，NTNbearing，SKFbearing，NACHIbearing，KOYObearing，HCHbearing，IKObearing]One of the countries。from
Roll bearing[bearing:bearing，thkbearing，trbearing，NSKbearing，NTNbearing，SKFbearing，NACHIbearing，KOYObearing，HCHbearing，IKObearing]The size of the mill is limited by the installation space（bearing[bearing:bearing，thkbearing，trbearing，NSKbearing，NTNbearing，SKFbearing，NACHIbearing，KOYObearing，HCHbearing，IKObearing]Inside diameter、The outside diameter depends on the diameter of the roll neck and roll body），bearing[bearing:bearing，t
When testing chromium steel and stainless steel as bearings[bearing:bearing，thkbearing，trbearing，NSKbearing，NTNbearing，SKFbearing，NACHIbearing，KOYObearing，HCHbearing，IKObearing]Material when the advantages，And it turns out theyre not just anti-rust。Chromium steel is the most common non-standard bearing[bearing:bearing，thkbearing，trbearing，NSKbearing，NTNbearing，SKFbearing，NACHIbearing，KOYObearing，HCHbearing，IKObearing]Materials。Its harder than stainless steel，So the service life is longer。Yet in the higher
SKFBearings are precision products。Therefore, these products must be handled with special care before and during installation。bearing[bearing:bearing，thkbearing，trbearing，NSKbearing，NTNbearing，SKFbearing，NACHIbearing，KOYObearing，HCHbearing，IKObearing]The trouble-free operation is largely related to the quality of the installation。 bearing[bearing:bearing，thkbearing，
To judge the removed bearing[bearing:bearing，thkbearing，trbearing，NSKbearing，NTNbearing，SKFbearing，NACHIbearing，KOYObearing，HCHbearing，IKObearing]Whether it can be used again，Be presentIKOCheck the bearing after washing。Carefully check the raceway surface、Rolling surface、State of mating surface、The wear condition of the cage、Flat bearing[bearing:bearing，thkbearing，trbearing，NSKbearing，NTNbearing，SKFbearing，NACHIbearing，KOYObearing，HCHbearing，IKObearing]The increase of clearance has nothing to do with it
one、From the perspective of use to ensure stable operation should pay attention to the following points： 1、Proper clearance，overshock，Too small, poor lubrication，Possible burning tile。 2、Rolling bearing[bearing:bearing，thkbearing，trbearing，NSKbearing，NTNbearing，SKFbearing，NACHIbearing，KOYObearing，HCHbearing，IKObearing]And the journal surface quality and geometry should be strictly guaranteed。 3、Improve lubrication quality，Control the oil pressure、Temperature and flow，Enhanced oil filtration。 4、Control the temperature state of diesel engine，In the feeling of too cold and too hot
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
(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
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
