Screw bolt Screw bolt，Mechanical parts，Cylindrical threaded fasteners for nuts。By the head and screw（A cylinder with external threads）A type of fastener consisting of two parts，It must fit with the nut，Used to fasten two parts with through holes。The following Feng Ye Xiaobian will take you to understand the industry application of screw bolts。
JTRFlanged linear bearing JTRFlanged linear bearing，A series of products with flanges on the outer wheel，Makes axial positioning easy；Bearing seat is no longer required，Become more economical。To get the low friction torque of the bearing、High rigidity、Good rotation accuracy，A steel ball with a small outside diameter was used。The use of hollow shafts，Ensure lightweight and wiring space。
TaiwanAMIThe lead screw support seat is the bearing that connects the lead screw to the motor，Construction with special features on the finished shaft end of standard ball screw stock，Standardized support units are preparedEK、EFtype，A standard support unit is prepared for the general ball screwBK、BFtype。The support unit on the fixed side is fitted with a pre-pressure adjustmentJIS5Grade angular contact ball bearing。

Hydraulic nut Hydraulic nuts are used for bolts that need to be disassembled frequently；Pretightening of oversized bolts；Large workpiece locking and other occasions。The working principle of the hydraulic nut is to use ultra-high pressure oil to produce a thrust on the shaft and a tension on the sleeve,Make the shaft and sleeve force evenly connected together。The following Feng Ye Xiaobian will take you to understand the characteristics of hydraulic nuts。
1、Cross slideMachine tool main component：body、workbench、Left and right columns、transom、Roof of longmen、The connecting beams are molded with resin sand、High quality high alloy wear-resistant cast iron,Annealed in hot sand pit→Vibration aging→Hot furnace annealing→Vibration aging→Rough finish→Vibration aging→Hot furnace annealing→Vibration aging→finishing,Completely eliminate the negative stress of machine parts,Keep the performance of the machine stable。 2、Cross sliding table beam lifting position for mechanical locking or hydraulic locking,Accurate positioning。 3、Cross beam vertical tool holder（Vertical milling head）Lateral feed、Side tool rest（Side milling head）Vertical feed is AC servo control,make-and-break、Continuous stepless feed。 4、The surface of the guide rail of the cross slide machine tool is quenched by ultra-audio hardening or point contact hardening,Its made from fine grinding。 5、The surface of workbench guide rail is bonded with high wear resistance guide strip。 6、Lubricated navigation achieves a
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。 summarize： The synchronous belt drive is composed of a circular belt with teeth of equal spacing on the inner surface and corresponding matching wheels。 It integrates belt drive、The advantages of chain drive and gear drive respectively。Rotational time，The power is transmitted through the tooth meshing with the tooth groove of the wheel。 The synchronous belt transmission has an accurate transmission ratio，No slip，A constant speed ratio can be obtained，Smooth transmission，vibration-absorbent，
With the rapid development of power electronic technology and new semiconductor devices ,Ac speed regulation technology has been continuously improved and improved ,Gradually improve the frequency converter with its good output waveform、The excellent performance/price ratio is widely used in AC machines。 Such as: A large electric motor used in rolling steel in a steel mill、Small roller table motor、Traction motors for railway and urban rail transit、Elevator motor、Lifting motor for container lifting equipment、Motors for pumps and fans、compressor、Electric motors for household appliances have successively used AC variable frequency speed regulating motors ,Good results have been obtained。The use of AC variable frequency speed regulating motor has obvious advantages over DC speed regulating motor： ( 1)Easy speed regulation ,And energy saving。 ( 2)Ac motor structure is simple、Small size、Low inertia、Low cost、Easy maintenance、durable。 ( 3)Can expand capacity ,Achieve high speed and high voltage operation。 ( 4)Can ach
Synchronous wheelCommonly used materials are: （1）Aluminium alloy（LY22or6028）:Light weight(Fit height)，rust-proof，Relative price45Steel price （2）steel（45steel）:High tooth surface strength is not easy to damage、Heavy weight，Rust prevention requires surface treatment(It is usually black on the surface) （3）Gray cast iron(HT250):Use when the wheel size is large，Additional mold casting is required during production，Good shock absorption （4）Orichalcum:Less use，Good mechanical and wear resistance （5）plastic(nylon):Less use，Light weight，wear-resistant，self-lubricating Synchronous gear tooth profile(Consistent with the tooth shape of the belt used)
snBearing housing model complete list Because one bearing can choose different bearing seats，At the same time, a bearing seat can choose different types of bearings，therefore,There are many varieties that bring bearing seats。SNThe top cover and base of the split bearing seat can be separated,Mainly bear the radial load,Self-aligning roller bearings and self-aligning ball bearings for cylindrical and tapered holes。The following Feng Ye Xiaobian will take you to understandSNBearing housing model complete list。
