Helium springs have so many features，yougetHave you finished?？What is a nitrogen spring？1.Nitrogen springs are commonly known as gas springs，It is the injection of high pressure gas into a closed cylinder(nitrogen: inignitability)，And the reaction force of nitrogen is used as a spring，Except for miniaturized features，A nitrogen spring can also exhibit a smaller spring constant under a larger initial load，Therefore, it is widely used in various machinery、furniture、Cars and office automation equipment。2.Universal mounting type nitrogen spring refers to the installation direction and the tilt Angle is unlimited when used，360°Can be used within the range，However, it is generally recommended to use the piston rod facing down。Helium (helium)
Servo electric cylinder product features1、 Compact structure，Small overall size，Easy to install and use，Simple maintenance，Low noise，Long life，Multiple security measures。2、 Precise position control，Repeatable positioning accuracy0.01mm, Add external displacement sensor reachable0.005mm。3、 Precise speed control，Speed waveform can be set arbitrarily，Achieve high-speed smooth and impact-free operation，The control accuracy can reach0.05%。4、 Precise thrust control，The control accuracy can be achieved by adding an external push-pull sensor0.5%。5、&
The characteristics of the motor base 1、Easy installation：It is equipped with standard support and fixed units，The motor can be easily installed using connectors。2、High precision：The ball screw and motor mounting part are integrated，This structure can effectively reduce the error between the two axes。3、High positioning accuracy：The connector is equipped with a special support seat for ball screw（Included radial angular contact pair bearing），Effectively control the axial swing of the screw。4、High rigidity：The connection material is made of high quality medium carbon steel，Strong impact resistance，durable。5、Machining accuracy：The deviation of concentricity is positive or negative0.01，Face perpendicularity at0.01。nut
What are the advantages and disadvantages of standard floating joints？advantage：1、Eliminate non-mechanical motion eccentricity，Shock absorption，buffer2、Protect the cylinder piston rod from bending caused by mutual forces，amorphosis3、Improve piston rod dynamic performance，Improve work efficiency4、High efficiency，Produce high quality products．5、Extend machine life，Reduce after-sales service．shortcoming：1.The universal ball is easily damaged。2.Relatively light load，Suitable for light duty only3.The connection thread is easily damaged，Service life only1-3years。
What are the characteristics of different materials of the synchronization belt？ Synchronous belt is made of steel wire rope or glass fiber for the 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。Different sync tape materials have different characteristics，There are mainly two kinds of materials：Neoprene rubber：Resistance to hydrolysis of neoprene synchro belts、heat-resisting、The impact resistance is better than that of polyurethane synchronous belt，Its transmission power range is large，Especially in high-power transmission，Theres nothing like a polyurethane sync belt。The operating temperature is generally -30～ 80The degree of。polyurethane：The teeth of the polyurethane synchronous belt should be provided
What are the different characteristics of oil-free bushings of different materials？Oil-free bushing is also known as self-lubricating bearing。Product composition material is mainly high force brass（SP2）+Lubricating material graphite，In the case of ensuring the bearing capacity between the shaft and the supporting surface，The friction between the shaft and the sliding body is reduced to achieve the purpose of low speed movement。Oil-free bushing mainly has the following materials：Copper alloy material：High temperature resistance、Corrosion resistance、Impact resistance and many other advantages。Suitable for heavy loads、Low-speed operation scenario，It is the most versatile product with comprehensive performance in oil-free bushing。Bronze material：This oil-free bushing is resistant to sintering，And do not bite the shaft during use，
What is the definition of a compression spring？What are the production processes？one、Definition A compression spring is a mechanical part，It takes advantage of the elastic and structural characteristics of the material，Deformation occurs during operation，To convert mechanical work or kinetic energy into deformation energy（Potential energy），Or put the deformation energy（Potential energy）Converted to mechanical work or kinetic energy。The most commonly used compression spring types are the outer diameter reference type and the inner diameter reference type。two、Production process1.roll2.Stress relief annealing3.Two-face grinding4.（Shot blasting）5.（alignment）6.（Stress relief annealing）7.Standing or pressure treatment8.（nigrescence）9.inspect10.Surface anti-corrosion treatment11.package*bracketing
Coating product process flow 1.Abrasive opener according to the packing parts drawing3DCarry out mold design(AL)，First-time abrasives are expensive，About half the cost，However, the subsequent same workpiece can save the cost of grinding tools,time-consuming1-2day。2.The workpiece is made according to the drawings provided，It takes about 30% of the cost2-3day。3.The initial processing of the coating is carried out according to the opened abrasive tool，It mainly has the modulation of adhesive material（hardness），Glue coating，Cover the mold with glue，Total proportion of cost and next step1About 20%。4.After finishing and cleaning, the coated parts are refined
Encapsulation products encapsulation is also known as“Secondary forming”，Take the rubber roller as an example--The rubber roller is made of iron，aluminum，Copper metal or other material as the core,A roller product of vulcanized rubber covering。The roller generally consists of an outer layer of glue、ebonite、Metal core、The roller neck and air vent are composed,Its processing includes roller core sand blasting、Bonding treatment、Adhesive molding、And surface processing and other processes。The role of rubber coated products：Protect the work piece from oxidation，Protect this piece from external erosion。Damping action The rubber is soft during the operation of the equipment，External workpieces provide shock absorption。Increasing friction. Colloidal substances can increase the coefficient of friction，General conveyor belt（encapsulating
