The base for installation has a connection、fastening、Prop up、Separation function，Mainly used in various fastening、Supporting mechanism。 The device has high space requirements(Need to save space)when，Installation bases are recommended。peculiarity： ①Be widely used，Various instruments such as cameras or sensors can be installed。 ②Anti-turning in the base、Simple disassembly parts can be selected according to the use。 ③support、There are many kinds of supports available，To meet the various needs of customers。
Screws use the physical and mathematical principles of circular rotation and friction of inclined surfaces of objects，A tool for tightening the components step by step。Screw is a general term for fasteners，Everyday words。 The main function of screws is to hold two workpieces together，It acts as a fastening device，Screws are used on general equipment，Like cell phones.，computer，CARS，bicycle，Various machine tools、equipment，Screws are used in almost all machines。 Screws are an indispensable industrial necessity in daily life：camera-like、Glasses、timepiece、A very small screw used in electronics;television、Electrical products、le
Mi screws are also called headless screws，Stop screw，The teeth are machine-wire teeth，Like a grain of rice，Thats why its called Machine，Some people also call it top silk。 Mainly used for mechanical equipment，Electronic equipment，Communication equipment，Hardware lighting，Various precision instruments and meters，plaything，On the lock。 Select machine screws need to pay attention to the following points： 1、When selecting machine screws, the size should be matched，Its one against one，Because even the most sophisticated technology can have problems。 2、When choosing a machine screw，A good way is to implement custom，Measure according to the size and requirements of your needs
The hole retainer is a tool to fix the axial movement of parts，Installed in a round hole，Used for axial movement of fixed parts，The outer diameter of this type of ring is slightly larger than the diameter of the assembly round hole。 Use circlip pliers when installing，Insert the nose into the clamp hole of the retainer ring，Clamp the retaining ring，Can be placed into the pre-machined circular hole slot。 The advantage of using the stopper for the hole： 1.Prevent bolt loosening due to vibration，Problems associated with loose fasteners no longer occur； 2.Ensure that the clamping force of the connector is maintained under strong vibration，Better to rely on friction from the lock tightening
Magnets are made of iron、cobalt、nickel，The internal structure of its atoms is very special，It has a magnetic moment。A magnet produces a magnetic field，Having an attractive ferromagnetic substance such as iron、nickel、Properties of metals such as cobalt。 Ndfeb permanent magnet material has excellent magnetic properties，Widely used in electronics、Electric machinery、Medical device、plaything、package、Hardware machinery、Aerospace and other fields。 The characteristics of various magnets are as follows： Neodymium magnet：It has a strong magnetic force in the current magnet of all materials，Powerful magnetic force in its small size。Its disadvantage is that it is easy to rust。It and cobalt magnets
towardsOType sealing ring，It has its own advantages in sealing。With regard toOMolded ring，What else do you know？You can learn from the following points。 1. OThe ring structure is simple，But because of its self-sealing effect good sealing。Use singleOv-ring，It has bi-directional sealing effect。 2. Stable sealing performance even under high pressure。No directivity when sealed，Can be sealed from both sides。 3. Low price，Rich in variety、Complete size。There are many kinds of materials，Can be selected according to different fluids:Nitrile butadiene rubber（NR
Safety warning labels are widely used in machinery manufacturing，Construction site，laboratory，Warehouses and other areas。 Product characteristics： ①Self-adhesive adhesive material，Attached to machinery and equipment，Storage cabinets, etc，Used to warn and alert people to potential dangers，Prevent accidents。 ②The logo pattern is bright and eye-catching and lasts as long as new，Outdoor weather resistance3Years or more。 ③High performance adhesive，Stick firmly，The edge does not fall off。 ④There are two sizes，A variety of patterns to choose from。 ⑤In Chinese, English and Japanese，Concise and easy to understand。&nb
Keyless expansion sleeve is a very common link part，It is a very important mechanical transmission component，Generally, we commonly use the expansion sleeve we will find that our expansion sleeve if it is touched by hand will find that there is oil on it。This is mainly because our expansion sleeve after the completion of production of our expansion sleeve manufacturers，It will expand a layer of lubricating oil for us to facilitate the installation and use of customers，So how should our expansion sleeve be installed！Now lets take a look！How to install the expansion sleeve and what should be paid attention to when installing。Expansion sleeve installation： 1.Three bolts should be placed in the screw holes of the flange during installation。&nb
The synchronous belt is made of 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。 The synchronous belt drive consists of an annular belt with equal spacing teeth on the inner peripheral surface and a belt with corresponding teeth
1、Definite action pattern2Single block method of energy saving winding A pulley block consisting of a moving pulley and a fixed pulley，There are two strand and three strand two winding methods，Both methods achieve the goal of saving labor，But the pull goes in different directions，There are three winding methods pulling upward；There are two ways to wind the wire pulling downward。 The most correct way to do this is to fix one end of the rope to the top pulley on the bottom，And then go up and round the bottom pulley on the top，Finish from the inside out。The free end of the rope should be pulled upward after winding（The number of moving and fixed pulleys is equal）。&nbs
