NSKDeep groove ball bearing suffixes are different，Its meaning is also different，For exampleC2Indicates that the radial clearance is less than the normal group，C3Indicates that the radial clearance is greater than that of the ordinary group，DFRepresents two single-row deep groove ball bearings paired face to face，DTIt also represents two single-row deep groove ball bearings paired in series。The following is an introduction aboutNSKDeep groove ball bearing series suffixes and the meaning of suffixes。Deep groove ball bearing series suffix：C2：The radial clearance is smaller than that of the normal groupC3：The radial clearance is greater than that of the normal groupC4：Radial clearance greater thanC3C5：Radial clearance greater thanC4DB：Two are paired back to back
Under normal circumstances，You are not recommended to install the nuts by yourself，Disassembly is not recommendedTHKBall screw nut，Especially high lead ball screw。The following is aboutTHKDetailed steps for mounting ball screw nuts，Here are a few points for your reference：①Clean the ball screw nut and ball。②Put the plastic bead holder(Ball degree reverser)Put it back in the nut。When installing the bead stopper, pay attention to the smooth connection between the inlet and outlet of the ball stopper and the spiral groove。③Grease inside nut。④Put the ball into the spiral groove。Look out，Not all spiral slots are filled，A bead holder is followed by a bead holder
With the improvement of linear motor technology，The application of linear motor is becoming more and more extensive，But there is very little information on the market，So many people do not understand linear motors。This kind of motor can be considered as a deformation of the rotating motor in terms of structure，It can be seen as a rotating motor cut along its radial direction，And then it flattens out and becomes。Linear motor mainly has the following advantages：1.Simple structure：Because the linear motor does not require an additional device to turn the rotating motion into a linear motion，Thus, the structure of the system itself is greatly simplified，Great reduction in weight and volume;2.High positioning accuracy：In the need for linear motion
Bearings are easily damaged during long-term mechanical operation，Then we have to maintain and check the bearings。Lets analyze how to diagnoseYTPLinear bearing management methods：The performance of the bearing to make it roll，It can maintain long-term use under good conditions，Bearings must be inspected and maintained，This inspection and maintenance（For bearing storage before loading, see attached bearing storage），It is important to prevent failure in advance，It is expected to operate according to standards suitable for the operating conditions of the machine，Perform regular inspections and maintenance，The following methods are generally adopted：1、In operation, the quantity is checked according to the rolling sound of the bearing、Vibration、Temperature check and lubricant
With the continuous increase of production，Crane working conditions are becoming more frequent and worse，The failure of gear couplings used in the drive system of the main lifting mechanism has increased significantly。Due to the wear of the tooth surface of this coupling，Gap increase，There is great impact vibration when lifting heavy objects，The gear and bearing of the reducer are seriously damaged，Sometimes the anchor bolts of the motor and reducer are loose，Severance，Even base failure。For this purpose, our factory1984At the beginning of the year, the main lifting mechanism transmission system of several major bridge cranes was reformed，Replace the gear coupling with a cross shaft universal coupling。Over the years，Good results have been obtained。Bridge crane used in metallurgy
With the development of innovation in the industrial age，Numerical control drive is widely used in automation。Everybody knows it isLSKLinear guide rail is a precision transmission component，In the process of operation, even the entry of dust will cause the combination accuracy coefficient of each part of the guide rail to decline。In addition, the linear guide rail is placed in storage，Also need to be extra careful，During transportation or storage，Assumed poor placement，Prone to bending and deformation，Therefore, we generally place it on the appropriate flat bearing，Hold horizontally，Assuming it has to be placed vertically，Then you need to calculate the force and check。It is understood，LSKThe deformation of the linear guide rail will
The main characteristics of horizontal planetary reducer are，The overall application is more extensive，Very high cost performance，Strong economic practicality，Long life，In the entire actual operation and control，Play a better servo rigidity effect，And can implement accurate positioning control。On the whole platform，Run more smoothly，Higher efficiency，High input speed，Less noise。Certainly in terms of the overall shape and structural design，It has its own unique characteristics。In the use of，You dont need to change the lubricating oil for a lifetime。No matter where it is installed，Can be effectively avoided during operation，A fully enclosed design appears，And throughout the protection process
Select the level of accuracy you want，Instead of going beyond the level of accuracy you need now to avoid unnecessary costs。Precision grade ball screw applications require accurate positioning、High reproducibility、Smooth movement and long life occasions。Manufacturing-grade ball screws are used where high efficiency and long life are required but where high precision is not an appeal。Precision manufacturing screw has a precision between manufacturingPMIBetween ball screw and precision grinding screw。Can replace many of the same precision grade grindingPMIApplication field of ball screw。High precision can be producedC6Grade precision manufacturingPMIBall screw，There are geometric tolerances different from precision grinding grade balls
There are more and more fake bearings on the market today，Let a lot of buyers of the boss do not know how to find a way out，It is getting more and more difficult to buy high-quality bearings。Here are a few steps to teach you how to tellNSKImported bearing quality，I hope it was helpful！one、The outer packing is clear under normal circumstances，The factory brandNSKImported bearings have their own specialized designers for external packaging design，And arrange the production of factories with satisfactory production conditions，Therefore, the packaging is very clear from lines to color blocks，In no uncertain terms,Some of the accessories of imported brands have special protection on the packaging
Shanghai YinKKLinear modules are different from linear motors，Be in touch with。They are all automatic transmission components，Can achieve linear motion，All kinds of parts are assembled on the aluminum profile and covered，It looks similar on the outside。1、The difference in the principle of linear motion is similar in appearance，But the principle of linear motion is different，Linear motor is the direct conversion of electrical energy into mechanical energy，Linear motion is achieved without an intermediate mechanism，The linear module requires a ball screw or a synchronization belt to convert the curved motion into a straight motion。2、The difference in speed Linear motors have considerable advantages in terms of speed。Speed of linear motor
