introduction：For every bearing，Each has its own speed limit，The speed plays a key role in the heating factor of the bearing，If the speed of a bearing exceeds the limit speed，Will lead toSKFThe temperature of the imported bearing rises，Lubricant drying，Resulting in the bearing stuck。SKFThe limit speed of imported bearings generally refers to the higher speed that can be achieved under the following conditions：1、Bearing tolerance is0level；2、Bearing clearance is0group；3、Bearing load is rated load10％（namely0.1C）；4、Lubrication and cooling conditions are normal；5、Radial bearings bear radial loads only，Roller bearings bear axial loads only；6、

introduction：We mechanical equipment people often use itCSKLinear guide，Working with linear guides almost every day，Be widely used in：Automatic dispensing machine、Automatic screw locking machine、Numerical control machine tool、Laser cutting machine and other equipment。In order to improve effectivelyCSKAccuracy of linear guide，Attention must be paid to the design of the product。First of all，In order to obtain a higher precision factor，The accuracy of the linear guide rail will not affect each other during manufacturing and use。and，If you want to make the guide precision high，The rail pair must have the characteristics of automatic lamination。Horizontal guides can be fixed by the weight of moving parts，The rest of the rails require elastic or roller pressure

introduction：This is despite the various grinding requirements inherent in the design resulting in the initial cost of square guides being several times that of circular guides，However, new manufacturing technologies and scale economics have allowed square guides to compete with circular guides in a wider range of applications。After entering the field of machine tools，In many applications where once only circular guide products could be used，It is now possible to see the use of square guides。It is understood，Square guide rail products can well meet the high stiffness、Requirements for high load applications，By precision grinding ball rails，Make the guide rail and ball accurately match，That is, the diameter of the ball guide rail running on the seat can only be slightly greater than the diameter。The ball itself counts

introduction：Mention the universal coupling，I believe that many machinery and equipment companies and enterprises have been in contact with or used，The large Angle of the universal coupling compensates for transmission efficiency，Making it one of the most widely used varieties in all coupling products。Today we will briefly introduce the universal coupling structure form and function。What are the functions of the universal coupling？First of all，Cardan axes are used to join two axes on different mechanical equipment（Drive shaft and driven shaft），Helps both axes rotate together，Achieve the effect of transferring torque。In addition, in the high-speed and heavy-duty power transmission，Part of the cardan shaft has a buffer、Damping and providing dynamic performance of shafting。Characteristics of universal coupling

introduction：We all know，Reducer as a very important auxiliary machinery，Its products cover a very wide area。And all this is closely related to the wide classification and type of precision planetary reducer，And one of the most important categories is volume。Though miniaturization looms as the way forward，But for different usage scenarios，The volume of precision planetary reducer still varies greatly。The following is a small series of Feng Ye Mall to explain to you what important factors are needed for choosing precision planetary reducer。1、Deceleration ratio The ratio of output speed to input speed2、The noise value is at the input speed of no load300

introduction：With the advancement of linear motor technology，The application of linear motor is more and more extensive，But there is little data on this in the market；Many people do not understand linear motors，The motor can be regarded as a structural deformation of the rotating motor。The motor can be regarded as a structural deformation of the rotating motor。It can be seen as a kind of rotating motor，Cut along its radial path，And then it flattens out and becomes。Linear motors have the following advantages：1、Simple structure：Because the linear motor does not need additional devices to change the rotating motion into a linear motion，The structure of the system itself is greatly simplified，The weight and volume are also greatly reduced。2、High positioning accuracy：When linear motion is required，straight

introduction：As everyone knows，Any mechanical equipment used for a long time will have problems of one kind or another，Shanghai YinhiwinThe same is true of linear guides。Because the guide rail always has a certain degree of wear during operation，Or theres a gap，Foreign body or something。At this time, the experienced operator can judge the silver by the soundhiwinWhere does the fault of linear guide rail actually occur，Here are two points for your reference：Teach you to judge silverhiwinOperation of linear guide rails：1、The sound of the machine is peaceful in normal operation，When the machine makes a high-pitched squeak，You need to be careful。It probably is

introduction：Why does the planetary reducer break its axis?The first occurrence of planetary reducer shaft breakagezuiThe big problem may be its own quality。Of course, this is what we normally think of，Among themzuiThe main reason is still the cause of the usual use of the process。For example, in the process of using a planetary reducer to accelerate and decelerate，What should we pay attention to to avoid the phenomenon of planetary reducer shaft breaking？1、During acceleration and deceleration，If the instantaneous torque multiplied by the instantaneous torque of the output shaft of the planetary reducer exceeds its rated output torque2times，And this acceleration and deceleration is too frequent，reducerzuiFinal cause

introduction：Stepper motor as a digital executive element，It has been widely used in motion control system。Many user friends in the use of stepper motor，It is felt that the motor has a large heat when working，Have doubts，I wonder if this phenomenon is normal。This paper will make a simple analysis of the heating problem and countermeasures of the stepper motor of Jiemekang，For your reference：It is understood，Every motor heats up，Its just a different level of fever。For all kinds of motors stepper motors，The interior is composed of an iron core and winding coils。Winding resistance，Electricity will cause loss，The loss is proportional to the square of the resistance and current，This is who I am
