The length of the period from the beginning of use to the appearance of the first material fatigue phenomenon is the number of revolutions of the guide rail、Load size、Lubrication is related to cleanliness。 Fatigue is the result of the shear stress under the load surface appearing periodically。After a period of time，These shear stresses cause tiny cracks 罏，And then gradually it extends to the surface，When the rolling piece passes through these cracks 罏，Some pieces fall off，It forms whats called peeling。Then it continues to expand as the skin is peeled，The guide rail is damaged and cannot be used。 The above is a description of fatigue，Its initial occurrence is below the surface
In the face of such a wide variety of modules do you know what product is more suitable for you？What price is more suitable？Do you live longer?？The following by Feng Ye Xiaobian to tell you about： 1、High precision linear module/There are two types of linear module ball guides。The first has excellent load capacity、High accuracy and long expected service life。The second is based on commercial design styles，Smooth and quiet operation，Very high precision； 2、Lead screw driven linear modules are designed for thrust、stiffness、Precision has high requirements for heavy loads、But there is no excessive requirement for speed，For example, in medium speed applications；&n
Stainless steel ball screw，Lead screw corrosion can be well avoided。For rolling parts products，Corrosion and wear are big problems，In the machine tool industry for a long time, it is preferred to use high-gloss polishing process to replace the coating or coating that may affect the surface hardness of the ball screw，Fine polishing technology can greatly reduce the corrosion of the primary point，Also use lubrication products with corrosion resistant additives，It can also play a good anti-corrosion role。 Use stainless steel ball screws in a clean environment，And use with dustproof cover, etc，Avoid dust and powder into the ball screw。Such as dust and powder due to poor dust prevention
Linear guide rails are mainly used in mechanical structures with high precision requirements and automated machinery，Linear guides are of high quality，High precision，Design safe products，However, it is inevitable that there will be failures in use，To reduce failures，Ensure safe use，Note the following during assembly： 1、Standard end caps are made of plastic。As a hard knock or bump，It will damage it，So pay attention。 2、If you disassemble each part without authorization，It will lead to the entry of dust or the reduction of the precision of the combination of various parts，For this purpose，If you dont have to，Please do not disassemble easily。&
Most bearings fail for many reasons——The load exceeds the original estimate，Ineffective seal、Too small bearing clearance caused by too tight fit。Each of these factors has its own special damage pattern and will leave special damage traces。 therefore，Inspect damaged bearings，Possible causes can be found in most cases，Broadly speaking，One third of bearing damage is due to fatigue damage，Another third is due to poor lubrication，The other third is due to pollutants entering the bearing or improper installation。 however，These damage patterns are also industry-specific。Such as
There are four ways to distinguish ball screw from ordinary screw： 1、Transmission efficiency The transmission efficiency of the ball screw is about90~96%，The transmission efficiency of the trapezoid screw is about26~46%。That is if driving the same large load，The use of ball screw can use less drive power，For example, lower power motors，It can reduce the cost，Can also reduce energy consumption。 2、Transmission speed Ball screw is rolling friction，Trapezoid lead screw is sliding friction，The temperature rise of the former is much lower than that of the latter，Therefore, it can undertake high-speed transmission tasks
Superb rolling bearing technology for linear guides，Advanced production plant，And superior quality standards，Make imported bearings famous all over the world，enduring。 It has been fully proven in millions of practical applications。The product is both economical and cost-effective and reliable for mechanical spare parts，Various sizes of rotation and linear motion are available，And all kinds of special techniques。 Products are widely used in various lathes、Grinding machine、Machine tool、Spraying equipment、Numerical control machine tool、Machining center、Measuring instrument、Confidential tester、corpuscle、Automatic machinery、Textile machinery、CARS、Food machinery、The medical
Bearing disassembly is regular maintenance，Change bearing。After removal，If continue to use，Or need to check the state of the bearing，Its removal should be carried out with the same care as its installation。Be careful not to damage bearing parts，Especially the removal of interference fit bearings，It is difficult to operate。 It is also important to design and manufacture disassembly tools as needed。At disassembly，The disassembly method should be studied according to the drawings、sequence，Investigate the fit of bearings，To obtain demolition work foolproof。 To remove the outer ring of the interference fit，A number of outer ring extrusion screws are prearranged on the circumference of the shell，Tighten evenly on one side，
Analysis and solution of causes of overheating of turbine reducer： 1、The transmission is poorly fixed，Turbine wear or damage，Bearing wear or damage，Bolt loose，Foreign body invasion Elimination method：Fixed gearing，Replacement turbine，Change bearing，Tighten the bolt，Remove foreign matter and change lubricating oil 2、Oil seal damage，Gasket failure，overoil，Oil plug loose，Oil mark failure Elimination method：Replace oil seal，Replace gasket，lubricate，Tighten the oil plug，Change oil mark，Input force or output shaft does not turn 3、Overheat of worm gear，Bearing loss
A nut is a nut，A part screwed together with a bolt or screw for fastening，All manufacturing machinery must use a component depending on the material，Split into carbon steel、Stainless steel、Non-ferrous metal（cupric）And so on several types。The installation of the nut in the ball screw determines the quality of the ball screw。Therefore, we should pay attention to the following points when installing ball screw nuts。1、Ball nut effective travel The ball nut should move within the effective travel，Limits must be configured at both ends of the trip，Avoid nut overshoot from lead screw shaft，And make the ball fall off。2、Ball screw drive efficiency is high due to ball screw nut secondary drive effect
