inKOYOBearings are often reflected by customers in the process of use[bearing:bearing（“Bearing”，Japanese person“Axial receptor”）It is a part that holds and reduces the friction coefficient of load during mechanical transmission。Can also be said，When other parts move relative to each other on the shaft，A device used to reduce the coefficient of friction during power transmission and to keep the center of the shaft fixed。]The temperature is abnormal during vibration。According to theKOYOBearing Group technology explains the factors that lead to this aspect are as follows：General bearing[bearing:bearing（“Bearing”，Japanese person“Axial receptor”）Is in machinery
NSKbearing[NSKbearing:Seiko Co., LTD（NSK LTD.）Be established in1916years，It is the first manufacturer to design and produce bearings in Japan。NSKThe function of the bearing fit is to makeNSKThe stationary ring and rotating ring of the bearing are respectively the stationary part of the installation part(Usually a bearing seat)And rotating part(Usually an axis)Solidify together，Thus, the basic tasks of transferring the load in the rotating state and defining the position of the moving system relative to the stationary system are realized。]Generation of medium vibration Generally speaking，rollNSKbearing[NSKbearing:Seiko Co., LTD（NSK LTD
xidao Milling cutter milling cutter Used for milling、A rotary tool with one or more teeth。When working, each cutter tooth successively intermittently cuts off the workpieces margin。Milling cutters are mainly used for machining surfaces on milling machines、step、groove、Forming surfaces and cutting workpieces。 There are many commonly used types of milling cutters according to their use（figure1 [Various milling cutter]）。①Cylindrical milling cutter：Used for machining surfaces on horizontal milling machines。The cutter teeth are distributed on the circumference of the milling cutter，According to tooth shape, it is divided into straight teeth and spiral teeth。According to the number of teeth divided into coarse teeth and fine teeth two。Spiral teeth coarse teeth milling cutter teeth less，
Determine the imported bearing under removal[Imported bearing:Simply put, the import bearing agent refers to the sale of an imported bearing brand。The main brands of imported bearings arenskbearing，ikobearing，fagbearing，Of good quality，Of course, the price is not cheap。]When it can be used again，Be presentINACheck bearing after cleaning，Check the raceway surface carefully、Rolling surface、State of mating surface、The wear condition of the cage、Whether the rolling mill bearing clearance is increased and whether there is any damage affecting the dimensional accuracy、abnormal。Non-separation type small ball bearings，Use one hand to flatten the inner ring，Rotate the outer ring to make sure it is smooth。 Bearing and other separate type shaft
one、Improper installation(Account for about16％) 1、Use brute force when installing，Hit the bearing directly with a hammer[bearing:bearing（“Bearing”，Japanese person“Axial receptor”）It is a part that holds and reduces the friction coefficient of load during mechanical transmission。Can also be said，When other parts move relative to each other on the shaft，A device used to reduce the coefficient of friction during power transmission and to keep the center of the shaft fixed。]Butt bearing[bearing:bearing（“Bearing”，Japanese person“Axial receptor”）It is a part that holds and reduces the friction coefficient of load during mechanical transmission。Can also be said，when
The gear reducer is an independent closed transmission device between the prime mover and the working machine，Used to reduce speed and increase torque，To meet the needs of the job，In some cases also used to speed up，speeder。 Performance characteristics Gear reducer is a combination of reduction motor and large reducer。Couplings and adapters are not required，Compact structure。The load is distributed on the planetary gears，Therefore, the carrying capacity is higher than that of the general helical gear reducer。Meet the needs of small space and high torque output。 Gear reducer Widely used in large mines，steel，Chemical engineering，Harbor，Environmental protection and other fields。withK、RSeries combination
Proper useINAImported bearing[Imported bearing:Simply put, the import bearing agent refers to the sale of an imported bearing brand。The main brands of imported bearings arenskbearing，ikobearing，fagbearing，Of good quality，Of course, the price is not cheap。]It is to prolong the service life of the bearing，The use of bearings must be clear about how to use bearings correctly，Due to the type of bearing、There are many different bearing types with different roles，It is difficult to have an in-depth understanding of bearings if you are not a professional，Here is Beijing Deremei Bearing Co., Ltd. for you
Contact fatigue failure refers to plastic bearings[bearing:bearing（“Bearing”，Japanese person“Axial receptor”）It is a part that holds and reduces the friction coefficient of load during mechanical transmission。Can also be said，When other parts move relative to each other on the shaft，A device used to reduce the coefficient of friction during power transmission and to keep the center of the shaft fixed。]The working surface is subjected to alternating stress and produces failure。Contact fatigue spalling occurs in bearings[bearing:bearing（“Bearing”，Japanese person“Axial receptor”）It is a part that holds and reduces the friction coefficient of load during mechanical transmission。Also can
Imported bearing[Imported bearing:Simply put, the import bearing agent refers to the sale of an imported bearing brand。The main brands of imported bearings arenskbearing，ikobearing，fagbearing，Of good quality，Of course, the price is not cheap。]Installation of：Imported bearing[Imported bearing:Simply put, the import bearing agent refers to the sale of an imported bearing brand。The main brands of imported bearings arenskbearing，ikobearing，fagbearing，Of good quality，Of course, the price is not cheap。]Whether the installation is correct，Affect the accuracy、Life span、property。therefore，Design and assembly department for imported bearings[
