Blacksmith Yunnan support seat In the field of automation，The support seat has always been a key product，It has become a variety of machine tools、CNC machining center、An indispensable and important functional component in precision electronic machinery。With the increasing application of linear guide，Technology improvement and product segmentation have become an inevitable trend，High-speed and environmental protection have become the development direction of linear guides。
Belt pulley，It belongs to disk hub parts，Generally the relative size is relatively large，The manufacturing process is generally cast、forging-based。Generally, the larger size is designed by casting method，The material is usually cast iron（Casting performance is good），Cast steel is rarely used（The casting property of steel is poor）；Usually smaller in size，Can be designed for forging，Material is steel。Belt pulleyIt is mainly used for long-distance transmission of power，For example, the power output of small diesel engines，Agricultural vehicle，tractor，CARS，Mining machinery，Machining equipment，Textile machinery，Packaging machinery，lathe，Forging bed，Some small horsepower motorcycle power transmission，Power transmission of agricultural machinery，Air compressor，retarder，Reduction gear，dynamo，Gin and so on。
Feng Ye Mall is one of the horse brand，Feng Ye mall the first imported guide rail，bearing，module，Screw and related accessories online trading platform，Goods for sale100%Genuine and licensed，7Hourly delivery，7Days unconditional return，70Cash on delivery in all cities，Provide solutions for industrial manufacturing，Keep your machinery running without worry，Make your business run hassle-free Synchronous beltIt is a steel wire rope or glass fiber as a strong layer，A circular tape covered with polyurethane or neoprene，The inner circumference of the band is toothed，Make it mesh with the toothed pulley。Synchronous belt drive，The transmission ratio is accurate，The force on the shaft is small，Compact structure，oil-proof，Good wear resistance，Good aging resistance，General service temperature-20℃―80℃，v<50m/s，P<300kw,i<10,It can also be used for low speed transmission where synchronization is required。
Angular contact ball bearingInstallation form，Theres back-to-back、Face to face and series to arrange three。Back to back（The wide end faces of the two bearings are opposite）At installation，The contact Angle of the bearing is diffused along the axis of rotation，The radial and axial angular rigidity of the support can be increased，High resistance to deformation；Face to face（The narrow ends of the two bearings are opposite）At installation，The contact Angle line of the bearing converges towards the axis of rotation，Its supporting Angle rigidity is small。
Lets introduce the characteristics of fiber grating sensors！
Drum brakes are often used on mechanical moving parts，It is an indispensable part of the operation of mechanical equipment。Drum brake is a kind of brake，How does it achieve braking during operation，Lets take a look at it。
As the preferred product for discrete control，PLCIt developed rapidly in the 1980s and 1990s，WorldwidePLCThe annual growth rate of the controller remains20%～30%。With the continuous improvement of factory automation andPLCThe capacity base of the controller market continues to expand，In recent yearsPLCGrowth is slowing in industrialized countries。however，In developing countries like ChinaPLCThe growth is very rapid。Synthesize relevant data，2004worldwidePLCThe sales revenue is100About $100 million，It occupies a very important position in the field of automation。
Synchronous beltpeculiarity： （1）Transmission accuracy，No sliding when working，It has a constant transmission ratio； （2）Smooth transmission，buffered、Damping capacity，Low noise； （3）High transmission efficiency，reachable0.98，Obvious energy saving effect； （4）Easy maintenance，No lubrication required，Low maintenance cost； （5）The range of speed ratio is large，Generally accessible10，The linear velocity is up to speed50m/s，It has a large power transmission range，From a few watts to a few hundred kilowatts； （6）Can be used for long-distance transmission，The center distance is reachable10mabove。 （7）Relative toVTape transfer，The preload is small，The load on the shaft and bearing is small；
For high speed variable frequency motor this thing，We need to understand it from its basic situation，Because the high-speed variable frequency motor itself is a more complex machinery，Especially for those of us who dont have professional knowledge。High-speed variable frequency motor can be said to be an improved version of variable frequency motor，Compared with ordinary variable frequency motor，The difference of high-speed variable frequency motor is the high-speed variable frequency design。The structure of high-speed variable frequency motor is also very complex，It is mainly composed of motor and Frequency changer And some important parts of the composition。Because the performance of high-speed variable frequency motor is very good，So now it has been widely used in various fields。
Three-phase induction motor(Triple-phase asynchronous motor)Its by simultaneous access380VThree-phase AC power supply（Phase difference120The degree of）A type of electric motor supplied with electricity，Due to three-phase asynchronous motorsThe rotor rotates the magnetic field in the same direction as the stator、Different speed into rotation，There is a slip，So its called three-phase asynchronous motor。 When the motors three-phase stator winding After the three phase symmetrical alternating current，Will create a rotating magnetic field，The rotating magnetic field cuts the rotor windings，Thus an induced current is generated in the rotor winding（The rotor winding is a closed path），The rotor conductor carrying current will generate electromagnetic force under the action of stator rotating magnetic field，Thus forming electromagnetic torque on the motor shaft，Drive motor rotation，And the direction of the motor rotation is the same as that of the rotating magnetic field。
