precompression，The purpose is to enlarge YintaiPMILinear guide slide block rigidity，Eliminate the internal load imposed on the rotating body in advance, such as clearance，IntimePMIClearance mark of the slide railZF、Z0、Z1、Z2andZ3Indicates that prepressure is applied（Preload）The rear gap value is negative。In addition，IntimePMIThe rails have all been adjusted according to the specified clearance before leaving the factory，So there is no need to adjust the prepressure。The appropriate gap should be selected according to various conditions，Please contact us when selecting。The prepressure grades of Yintai linear guide slide blocks are respectively：Light precompression，Intermediate precompression，repreload，Superheavy preloading。Light precast
As everyone knows，Bearing is an important part of contemporary machinery and equipment。Its main function is to support the mechanical rotating body，Reduce the friction coefficient during its movement，And ensure its rotation accuracy。Let me tell you more aboutINAImported bearing measurement specification and error regulation，Here are a few points for your reference：⑴The specification of the size reference is carried out by comparative measurementINAMeasurement pairs of dimensional tolerances of imported bearings，The measurement block or standard part is specified as the dimensional basis for comparison measurement，The measure block must meet the standardJB／T1078《Gauge block》Regulation of...，Standard parts must comply with the regulations of the competent authority of the manufacturer
Linear module is a kind of high precision linear drive mechanical part，It has a wide range of applications、Simple collocation、The precision is also relatively high，It is usually widely used in automation equipment and assembly lines。Precision position positioning technology is supported by todays manufacturing equipment、Measurement equipment and high-density intelligence machines are one of the basic technologies to achieve high precision and high speed，It is also one of the criteria for judging high-quality linear modules。In that way，Shanghai YinkkHow to design the linear module with reasonable positioning mechanism，Enables it to achieve high precision，Here are a few points for your reference：1、High precision motion reference；High precision motion is usually mechanical motion
In order to protectTBIVerify the reverse transmission accuracy and axial stiffness of ball screw，Must eliminateTBIBall screw nut auxiliary axial clearance。The method of eliminating the gap is often used double nut structure，Use the relative axial displacement of the two nuts，The balls in the two ball nuts are attached to the opposite sides of the spiral raceway，When the axial clearance is eliminated by pretightening in this way，It should be noted that the pre-loading force should not be too large，Excessive preload increases the no-load torque，Thus reducing transmission efficiency，Shorten service life。There are several ways to reduce or eliminate the back backlash of ball screw assemblies，The back clearance is the clearance between the ball bearing element and the screw and nut raceway
Delta400WServo motor running unstable cause as a controller，Servo drivers are often used to control servo motors，In positioning systems that require high precision，Servo driver is a very important part of servo system。For Delta400WServo motor running unstable，The main reasons for this failure are as follows：1、Servo drive parameters are improperly adjusted，The regulator is not in good working condition。2、Due to interference、Unstable speed feedback signal caused by poor connection。3、The tachometer generator is poorly installed，Or the tachometer generator is poorly connected to the motor shaft。4、Servomotor carbon
Nut rotaryTBIThe ball screw is a nut rotating ball screw device which integrates the single nut ball screw and the support bearing。The nut is a steel ball circulation structure using a circulator，The ball is moved along the circulator groove mounted inside the nut to the adjacent rolling surface,Then cycle through the load area,Thus, infinite rolling motion。It is understood，Rotary nut typeTBIThe ball screw is produced by fitting a suitable bearing jacket on the outer diameter of the nut，The movement through which the nut rotates or stops，You can create a rotation or spiral motion through an axis。This type of screw is often used for rotating motion and straight lines
With the large-scale application of servo system，Servo-drive use、Servo driver debugging、The maintenance of servo drive is an important technical topic in servo drive nowadays，More and more service providers of industrial control technology have conducted in-depth research on servo drive technology。A servo driver is a controller used to control a servo motor，The action of the servo driver is similar to the action of the frequency converter on the ordinary AC motor，Part of the servo system。The control mode and application of servo driver are introduced，Here are a few points for your reference：⑴Closed loop control Because of the precision of open loop control can not meet the requirements of machine tools，In order to improve
In all mechanical equipment，The grade of the machine iszuihigh，Lets say you want to produce gears with seven levels of precision，The machine must be one precision grade higher than the gear；To manufacture a screw with seven levels of precision,The precision of the lead screw of the machine tool used for processing the screw should also be at least higher than eight levels。IntimePMILinear guide rails are characterized by high rigidity and high precision，It has been widely used in precision machine tools。IntimePMILinear guide accuracy can be divided into walking parallelism、Pairwise difference of height and pairwise difference of width。Among them, the walking parallelism is YintaiPMICore accuracy of linear guide，It is called guideway positioning accuracy，It fully embodies
The generation of vibration in bearings in general，Rolling bearings themselves do not produce noise。Commonly felt“Bearing noise”In fact, the bearing directly or indirectly produces a sound effect of vibration with the surrounding structure。This is why many times the problem of noise can be seen as involving the wholeNSKVibration problems of imported bearing applications。Raceway sound is a steady and continuous noise caused by the rolling element rolling in the raceway when the bearing rotates，It attracts attention only when its sound pressure level or tone is extremely high。In fact, the sound energy stimulated by raceway sound is limited，As in normal circumstances，Of high quality6203Bearing track sound is25～2
Linear modules can be used in a variety of industries to increase production efficiency，Its high positioning accuracy also brings about the improvement of product quality。Different models are suitable for different products，Multiple models of linear modules are available，And each has its own characteristics。So ShangyinKKWhat are the categories of straight line modules？Different kinds of silverKKWhats the difference between a straight line module？Below with the Feng Ye mall Xiaobian together to see it！The linear modules of open synchronous belt type and ball screw type are mainly divided into open synchronous belt linear module and open ball screw linear module，And both have high stiffness、Easy to install、Easy maintenance、Small body size
