There are many kinds of failure forms of ball screw，No fixed pattern。The occurrence of failures is often gradual，Sometimes it increases gradually over time，These failures generally appear gradually over time，These failures generally develop gradually over time。This failure is caused by various unfavorable factors and external factors。therefore，Determine the true cause of the failure through proper testing，Is the premise of fast and accurate maintenance。In that way，What are the test methods for the accuracy of the mounting part of the ball screw for medical devices？Here are a few points for your reference：1.Part mounting part to screw shaft
Introduction of several process characteristics of linear motor，Here are a few points for your reference：1、Accuracy reliability Linear motors do not use drive components such as retarders，The motor is directly connected to the load to drive，The problem of precision fluctuation caused by gear wear can be avoided，It is beneficial to realize the precision of the device、High-end oriented，Provides the overall accuracy of the equipment。Linear motors do not use ratchets、CAM and other intermittent moving parts，The rotation position of the load is adjusted by directly connecting the motor to the load，The problem of inaccurate positioning caused by the loss of intermittent moving parts can be avoided，It is beneficial to realize the indexing operation of Zhangs、sway、Continuous operation，
With the development of industry and machinery manufacturing，All kinds of machinery and equipment with complex functions are constantly flooding，Their appearance has brought new vitality to our economic development。Among them, the coupling is a transmission component used in many large mechanical equipment，Today we will talk about the type and carrying capacity of the coupling？What are the two types of coupling：Theres a traditional straight claw type，The other is a surface（indentation）Claw type zero clearance coupling。The traditional straight claw coupling is not suitable for high precision servo drive applications。Zero clearance clave-type coupling is evolved on the basis of the straight clave-type，
Precautions for the use of planetary reducer lubricating oil：Selection of grease When choosing grease according to the bearing load of planetary reducer，For heavy loads, grease with small penetration should be selected。When working under high pressure, except the needle penetration is small，It also has a high oil film strength and extreme pressure function。When choosing grease according to environmental conditions，Calcium-based greases do not dissolve easily in water，Suitable for dry and less moisture environment。When choosing grease according to operating temperature，The main indicator should be the drop point，Oxidation stability and low temperature function，Drop points are generally used to evaluate high temperature performance，The actual operating temperature of the bearing should be lower than the drop point10-20℃。The operating temperature of the synthetic grease
With the needs of market development，The use of machinery in various industries is very large，Linear bearings play an increasingly important role in the market。Linear bearings are a kind of high precision、Low cost、Linear motion system with low friction resistance。MYTLinear bearings are used in combination with guide shafts，A direct motion system that uses the rolling motion of the ball to realize infinite linear motion。MYTLinear bearing is subjected to excessive impact load when moving and reversing，Or when the bearing is stationary，Due to machine vibration and other factors will cause the contact to form a pit。External hard particles enter the bearing，Indentation can also be formed on the contact surface，This long-term deformation exceeds a certain amount
When does the upper silver ball screw need to be prepressed?There are several ways of preloading?Feng Ye Mall Xiaobian believes that the prepressure and prepull of the silver ball screw are to eliminate the axial gap，Increase the rigidity of the ball screw pair，Reduced ball body、Elastic deformation between screw and nut，Achieve higher accuracy。One of the characteristics of the upper silver ball screw is to increase the rigidity of the screw through pre-pressure。To be able to increase the rigidity，Must use"precompression"Reduce the clearance between the ball and the lead screw。After applying pre-pressure，To achieve precise positioning operations。however，The value of the pre-pressure is very important，Must use appropriate
With the increase of automated factories，The transmission parts used have also increased a lot，The whole presents a dominant position。Linear guide rails are used as precision transmission components，Although the current technology，It can ensure that the components can operate normally in a normal environment，But in the course of daily operation，The environment in which the device is located is not ideal；therefore，The guide rail also needs careful maintenance。In that way，With regard toNSKWhat are the storage methods of linear guide lubricants？In the daily operation of the linear guide rail without the use of lubricants。With the increase of lubrication varieties，How to effectively and reasonably use lubricants to achieve the expected management of linear guides
Linear motors convert electrical energy directly into linear motion mechanical energy，No intermediate transfer mechanism is required for the transmission。Has a large starting thrust、High transmission stiffness、Fast dynamic response、High positioning accuracy、Unlimited travel length and other advantages。So what are the advantages and disadvantages of linear motors?The text will introduce you in detail：one、Advantages of linear motor：1、No mechanical contact，The transmission force is generated in the air gap，There is no friction other than linear motor guide。2、Simple structure，Small size，Our linear drive is achieved with fewer parts，And thats only one movement
FAGImported bearings are an indispensable part of machinery，The scope of its use will also be more and more extensive，Because you need it anywhere you can turnFAGImported bearing。FAGImported bearings are mainly used to support and reduce friction in machinery，thereforeFAGPrecision of imported bearings、Noise is directly related to the use and life of the machine。However, business personnel often encounter some customers that use better bearings or imported bearings whose efficiency is not high，This is what mattersFAGThe use and selection of imported bearings。The following will mainly use a wide range ofFAGUse and selection of deep groove ball bearings
Synchronous tape module is a kind of linear module，Has made great contributions to the machinery manufacturing industry。It consists mainly of belts、Linear guide、Aluminium alloy profile、coupling、motor、Photoelectric switch and other components，Is a mechanical structure that provides linear motion，The transmission mode is completed by belt and linear guide rail。Heres how a synchronous tape module works：Driven by motor（Servo motor or stepper motor）The driving wheel that drives the synchronization belt rotates，Then the belt drives the slider on the linear guide rail to move back and forth。The belt tightness on one side of the synchronous belt module is specially designed，Can be adjusted according to production needs。The accuracy of the synchronous tape module depends
