In the process of processing，IntimePMIThe noise that often occurs when the ball screw is used，But if you usually pay more attention to maintenance，It would be a rare occurrence。So pure YintaiPMIThe problem with ball screws is that they dont make too much noise，The general causes of noise are as follows：1.Because the dimensions in the original nut are the same，Plus its tightly sealed with oil，So it doesnt make too much noise。However, if the use time is too long, the ball should be replaced，And to be a better match，Beads of a different size than the previous ball were used for installation，Plus nuts for load operation
Simple diagnosis of rolling bearing fault detection using bearing vibration signal analysis method of fault diagnosis，It can be divided into two kinds: simple diagnosis and precision diagnosis。The purpose of simple diagnosis is to make a preliminary judgment of the objects listed in the diagnosisKOYOWhether the rolling bearing is faulty；The purpose of precision diagnosis is to determine what is considered to be a fault in the simple diagnosisKOYOBearing failure categories and reasons。The following mainly introduces several methods of simple diagnosis：（1）The amplitude value here refers to the peak valueXP、Mean valueX（For simple harmonic vibration is the average value in half a period，The impact vibration of the bearing is compared
The ball spline pair is a linear motion system，When the spline sleeve uses the steel ball in it to move in a straight line on a finely ground spline shaft，Can transmit torque。The spline pair has a relatively compact structure，Can transfer excess load and power，And has a long life。whenTBIBall spline in processing，You can feel the vibration when you put your hand on the machine，And there will be a certain amount of noise，Is this normal？With regard toTBIThe problem of noise generated by the ball spline during processing，It needs to be analyzed in accordance with specific circumstances。1、TBIThe ball spline makes noise when it travels in a certain axis。For example
The contact area between the universal coupling and the cone shaft is not enough，Is a problem that many enterprises will encounter，The reason may be that the measurement before selection is not accurate enough。In that way，How to deal with this situation？Here are a few points for your reference：1、The first thing we need to do is stain the axial cone,Apply a thin layer of red lead oil evenly to the cone of the shaft,Put the hub in place according to the mark made by the root manufacturer or disassembly,Use your hands to make contact,Remove hub to check shaft hole surface。It can be seen from the surface dyeing of the shaft holes,Deep in the color are areas where the contact is tight,The light color is the area just touched,Colorless is no contact
Every machine in our lives is installed in a different way，Especially some more difficult to operate machinery，In that way，How to install the single-axis linear module to improve our efficiency？The installation method of single-axis linear module can be divided into locking type installation and locking type installation,The suitable installation method can be selected according to the condition of the current operating platform。If the lock installation is selected,Remove the antifouling cover first,Place the hex screw over the base of the single-axis linear module itself,The lock is attached to the screw hole of the installation service platform。If you choose to lock down the installation,Pass the screw over the mounting service platform,The lock is attached to the screw hole of its own base。Ann
Various problems may occur during the use of the ball screw for medical devices，Some problems are accidental，Some are progressive；It gets worse over time，There is no fixed form，And chance is a sudden problem。As usual there are no prominent symbols，Spring into，This kind of problem is caused by all kinds of unfavorable factors and external influences。It is through the process of accurate testing to identify the real cause of the problem，It is the condition of rapid and accurate repair。For example, the dial indicator of the measuring lead rod does not swing when the positive and negative migration of the medical device lead rod changes，Clarify that the lead screw is not moving。Such as dial indicator hands
A servo system is the use of a component(As a lever)The function of the system can make the state of the system reach or approach a predetermined value,And can be the desired state(Desired value)Compare it to the actual state,According to their differences(Sometimes its the rate of change of that difference)An automatic control system to adjust control components。Can be called“Servo controller”Its in its location、speed、Whether the servo response and control accuracy of all aspects of the output force can meet the requirements of use，Its not about what motor actuator is used。The drive controller of servo system is based on the development of frequency conversion technology，The current loop inside the driver，Speed loop and position
whenTBI1204Ball screw after medium frequency induction hardening，On the surface and under the teeth0.5mmThe hardness is qualified，But the hardness of the tooth base is low，What causes it？The following content is revealed for you：This situation should be caused by adjusting the position of the sensor，Try to keep the product in the center of the sensor，Dont play favorites。It can also be done by reducing the quenching power and shortening the heating time。The primary cause may be rapid surface cooling，Dental base cooling diffuse，Cause the surface and the tooth base hardness difference，If possible, measures may be taken to narrow the difference,Ball screw quenching is a certain difficulty,There are many details.,rare
Good Rexroth linear guide slider to use、Lubrication and storage can not only make the guide rail play stable、Precise performance，It can also extend the service life of Rexroth rail to a certain extent，So were using、What problems should be paid attention to when lubrication and storage？one、Lubrication Lubrication is very important for the smooth sliding of Rexroth linear guide sliders，The lubrication of the slider can be done from the following aspects：1、Lubrication before use，Under normal circumstances, linear guide manufacturers will apply anti-rust oil for the guide rail when they leave the factory，So we must wipe the above anti-rust oil and add lubricating oil before the first use，Specific use
Bearings are widely used in rotating machinery，It is also one of the most vulnerable components。Many failures of rotating machinery are related to bearings，The working quality of the bearing has a great impact on the working state of the machine，Its defects can cause abnormal vibration and noise，Even damage the equipment in severe cases。GermanyINAThe deterioration of needle roller bearings is not a linear process，Its an exponential process。In different stages of deterioration，Fault information occurs in different frequency bands，Therefore, different fault detection methods should be adopted。At present, the industrial field generally believes that GermanyINAThe deterioration process of needle roller bearings can be divided into four stages，for
