Speaking of couplings，Maybe everyone is familiar with it？In the installation of mechanical equipment，Couplings are often used，The coupling serves as an intermediate carrier connecting the two axes，Widely used in petrochemical metallurgy electroplating and other industries，But a coupling is a mechanical part that connects the ends of two shafts so that they can rotate together and transmit torque。The following Fengye Mall Xiaobian will introduce the role of double diaphragm coupling in detail、peculiarity、What are the installation methods？Characteristics and applications of double diaphragm coupling：Wide range of torque control，High control precision。Torque is proportional to the excitation current over a fairly wide range，Can improve、Simplify the control of transfer torque，usable
There are many types and brands of servo motors on the market today，The parameters of different models and brands are also different，How to choose a servo motor has become a very troublesome thing for enterprises，The following Xiaobian will give you a talk about the steps of choosing servo motor specifications：Each type of servo motor has a rated torque in the specification、Large torque and motor inertia and other parameters，There must be correlation between each parameter and load torque and load inertia，The output torque of the selected motor should meet the requirements of the motion conditions of the load mechanism，Like the speed of acceleration、Weight of mechanism、The way the mechanism moves(level、perpendicularity、rotate)Etc.；shipment
When choosing linear guide，JapanTHKThe life of the linear guide is an important factor in our selection，So how to calculate the life of the guide rail？When calculating the rated life，The influence of external action loads and use occasions should also be considered，Weight of object、The change of inertial force caused by the speed of motion，A load factor is introduced for this purposefW。Under different conditions of usefWvalue，See table below on the left。Rolling linear guides in most workplaces are composed of2OR2Use more than one slider in combination，Therefore, it is necessary to consider the influence of the uniform load distribution on the life，The contact coefficient is introduced in the calculationfC。The contact coefficient is the same as the slide block on the shaft of the guide rail
TBIThe ball screw converts the rotary motion into a straight line motion，Or the ideal product for converting linear motion into rotational motion。Because it has very little friction resistance，TBIBall screws are widely used in such CNC machine tools and precision instruments。I believe you all know that，TBIBall screw reverse error is a common problem，This problem seriously affects the working accuracy，It greatly reduces work efficiency。At this time, every technician needs to graspTBICommon problems and solutions of ball screw，Minimize impact。one、Causes of large reverse errors：1.TBIThe ball screw preload is too tight or
Linear guide rail is the main parts of industrial automation，Its applicability is strong，Suitable for a variety of automated production lines。Linear guide selection is more complicated，In addition to the need to understand the length of guide rail in the selection，There are many other parameters to understand，Such as：Width of guide，precision，Scope of application，Size and number of sliders assumed，computezuiHeavy load，Calculate service life and other parameters。Lets take a look at IntimePMILinear guide rail length selection tips bar。1.Pay attention to the length of guide rail when confirming：Many manufacturers produce large specifications of linear guide lengthzuiBe long4000mm，As well as5600mmlong
With the continuous development of technology，The future will enter a new era of intelligence，Traditional manual manufacturing will be replaced by mechanization。This is certainly where a trend lies，distance4.0The craft is not far off。Learned from the CNC machine tool industry，Shaft support、SKFBearing seat and shaft support rail applications are very many，So what are the characteristics of them today？1.Smooth running、Low noise linear bearing and shaft contact sliding，Minimal friction resistance，So the operation is very smooth。2.The assembly of interchangeable easy linear housings has been standardized、normalization，And strict accuracy requirements，So in assembly or maintenance
How to select Airtek cylinder？In cylinder selection，Should be based on job requirements and conditions，Select the right type of cylinder。The following is a single piston rod double acting cylinder as an example to introduce the cylinder selection steps：①Cylinder bore：The output force of the cylinder is determined according to the bearing force of the cylinder，From this, the diameter of the cylinder is calculated。②Cylinder travel：The stroke of the cylinder is related to the occasion of use and the stroke of the mechanism，But generally do not choose a full trip。③Cylinder strength and stability calculation④Installation form of cylinder：The installation form of the cylinder depends on the installation position and the purpose of use。In general，Fixed cylinder is used。Work as needed
The planetary reducer matches the speed and transmits the torque between the prime mover and the working machine or the actuator，Its a relatively sophisticated machine。The purpose of using a planetary reducer is to reduce the speed，High torque。With the rapid development of mechanical automation industry expansion，Planetary reducer has also been widely used in various places，But the service life is not the same length。The service life of some can be as long as ten years，And some of the service life is only a month or two，And the factors that lead to this are other than quality，The use environment is also one of the key factors affecting it。In that way，Environmental life of planetary reducer
Most commonly used diaphragm couplings have been standardized or normalized，Under normal circumstances, only the correct choice of coupling type、Determine the coupling model and size。In necessity，The load capacity of the vulnerable weak link can be checked and calculated，High speed，The centrifugal stress on the outer edge and the deformation of the elastic element should also be checked，Balance check, etc。When choosing the type of coupling，Several factors should be considered：1、The size and nature of the torque required to be transmitted and the requirements for the damping function。Such as，Heavy duty transmission for high power，Optional gear coupling；For severe impact loads or requiring the elimination of torsional vibration of shafting
For Airtac cylinder equipment，The failure phenomenon that occurs within two to three months after the start of its operation is called early failure。Under normal circumstances，There are basically four different reasons why this can happen。Below we will introduce the relevant content for you，For your reference。The cylinder has internal and external leakage during operation，The main reason may be because the piston rod appears eccentric during the installation process，Short supply of lubricating oil，And wear and tear of the seal ring or seal ring、Caused by impurities in the cylinder。If the cylinder has the above condition，Need to re-adjust the piston rod
