Linear modules are widely used in the field of automation industry，It is being developed in different areas of automation industry，Relatively large differentiation。So select the linear moduleWhen considering various factors，Here are some of the factors that need to be examined。 1、Vibration resistance and stability：Stability refers to the performance of no self-excited vibration under a given operating condition；Vibration resistance refers to the ability of the module to accept forced vibration and shock。 2、Stiffness is particularly important for precision machinery and instruments。Module deformation includes the deformation of the guide body and the contact deformation of the guide pair，The ability of the guide rail to resist force deformation。The deformation will affect the relative position between the components and the guiding accuracy。Both should be considered。 3、Motion sensitivity and positioning accuracy The motion sensitivity of linear guide refers to the small stroke that can be achieved by the movi
1895years，TIMKENHenry Timken, founder of the Timken Company·Mr. Timken invented a bearing for the axles of the day that used conical rollers，It is a tapered roller bearing（Tapered Roller Bearings），The company was thus established。TIMKENThe company is a world-leading manufacturer with a century-old history，Its high quality bearings、Alloy steel and related products and services are everywhere，Whether on land、Ocean or space。 Deep groove ball bearings are suitable for high speed or even extremely high speed operation，And very durable.，No frequent maintenance required。The friction coefficient of this kind of bearing is small，Limit speed height，Varied in size range and form，Application in precision instrumentation、Low noise motor、CARS、Motorcycle and general machinery industries，It is a kind of bearing widely used in the machinery industry。Mainly bear radial load，It can also withstand a certain amount of axial load。 Timken ball bearings are designed specifically for aviation applications to withstand radial
Angular displacement sensor： The sensor uses a specially shaped rotor and a wire winding coil，Analog linear variable differential sensor（LVDT）Linear displacement of，High reliability and performance，The rotating motion of the rotor shaft produces a linear output signal，Move around the factory preset zero±60（In all120）The degree of。 The phase of this output signal indicates the direction of displacement away from zero。The non-contact electromagnetic coupling of the rotor gives the product unlimited resolution，That is, the absolute measurement accuracy can reach a few tenths of a degree。 An angular displacement sensor is a displacement sensorOne of the models，Non-contact patented design，Compared with other traditional angular displacement measuring instruments such as synchronous analyzer and potentiometer，Long-term reliability is effectively improved。Its design is unique，In no use such as slip rings、lamina、Contact cursor、Measurement accuracy can be guaranteed under the premise of easily worn moving par
All conveyor belts must be looped to be used，Therefore, the quality of the conveyor belt joint directly affects the service life of the conveyor belt and whether the conveyor line can run smoothly。 General conveyor beltCommon methods of joint are mechanical joint、Cold bonded joint、Hot vulcanized joints, etc。 There are three common methods for conveyor belt joints Conveyor belt mechanical joint method： Generally refers to the use of belt buckle joints，This joint method is convenient and convenient，Also relatively economical，But the efficiency of the joint is low，Easily damaged，It has certain influence on the service life of conveyor belt products。 PVCandPVGWhole core flame retardant anti-static conveyor belt connector，normal8The products below the stage are all using this joint method。
The belt buckle is used to attach the conveyor beltThe main material of。High quality and high strength alloy plates are generally used for mining strong belt buckles，Saline-alkali tolerance，moisture-proof，The front end nails have strong penetration，Use high quality materials，High riveting strength，Make up for the vulcanization transport time、Be strenuous、Costly deficiencies。 The strong belt buckle is used as a belt connection buckle for transportation，Material matters，Because the buckle is too hard and it will damage the belt and scratch the roller，The material is too soft and will cause insufficient tensile strength and wear resistance，Shorten the life of the belt buckle。

A relay is a device that uses the effect of an electric current to close or disconnect a circuit，For active maintenance and active control。In most cases，A relay is an electromagnet，The armature of this electromagnet can close or break one or more contact points。When there is an expiration of current in the winding of the electromagnet，The armature is attracted by an electromagnet，This changes the condition of the contact。
Pressure relays can sense the pressure of the system，And emit a switch signal。Under pressure，Normally open contact is closed，Normally closed contact opens。We can take advantage of it procedurally。But in actual use，Were going to have some problems。
