thkGuide rail China general With the use and prosperity of machinery，THKGuide rails are also widely used as general parts of machinery，Along with the development of economy，inTHKThe corresponding integrity in the guideway industry has been reduced a lot，With the development of The Times，A lot of automation parts suddenly a lot of imitation products from the followingthkGuide rail China total Feng Ye mall to take you to understand how to identifyTHKTrue or false guide：
thkrailssr25 Linear guides can be divided into：Roller linear guide，Cylindrical linear guide，Ball linear guide，Three kinds of，Its used to support and guide moving parts，Reciprocating straight motion in the given direction。It depends on the frictional nature，Linear motion guides can be divided into sliding friction guides、Rolling friction guide、Elastic friction guide、Fluid friction guide and other types。
nbBearing official website Japan nbBearing is a linear motion system，Used in combination with linear travel and cylindrical shaft。Due to the bearing ball contact with the bearing jacket point，The steel ball rolls with little friction resistance，Therefore, linear bearings have low friction，And relatively stable，Does not vary with bearing speed，Can obtain high sensitivity、Smooth linear motion with high accuracy。Linear bearing consumption also has its limitations，The main thing is that the bearing impact load capacity is poor，And the carrying capacity is also poor，Secondly, the vibration and noise of linear bearings are larger when moving at high speed。The automatic selection of linear bearing is included。Linear bearings are widely used in precision machine tools、Textile machinery、Food packaging machinery、Sliding parts of industrial machinery such as printing machinery。

Cylinder producer The cylinder is，A cylindrical metal part that guides the piston to move in a straight line in a cylinder。Air in the engine cylinder expands to convert thermal energy into mechanical energy；The gas in the compressor cylinder is compressed by the piston and the pressure is increased。
Thin cylinder The thin cylinder is a cylindrical metal part that guides the piston to move in a straight line。The working medium converts thermal energy into mechanical energy through expansion in the engine cylinders；The gas in the compressor cylinder is compressed by the piston and the pressure is increased。turbine、The case of a rotary piston engine, etc., is also commonly called“Air cylinder”。Below, Feng Yes small edition will take you to understand the thin cylinder structure：
one、Use gas-liquid pressurization cylindersAdvantages and disadvantages： 1、Advantages of using pneumatic transmission (1)、Easy access to power sources,Simple storage and recommendation； (2)、Little pressure，No explosion risk； (3)、Simple pipeline configuration，Cheap repair； (4)、Pneumatic transmission speed is faster，Easy to adjust； (5)、Low operating temperature，No overtemperature phenomenon； (6)、Light weight，Easy handling； (7)、Clean working environment without oil leakage； (8)、The right price。
Speed motor refers to the reducerElectric mixer（motor）Ensemble of。This integration is also commonly referred to as a geared motor or a geared motor。Usually by a professional reducer production factory，After integration and assembly，With motor integrated complete supply。 It is usually supplied in complete sets after integrated assembly by professional reducer manufacturers。Gear motor is widely used in steel industry、Machinery industry。The advantage of using a gear motor is to simplify the design、Save space。After World War II，The rapid development of military electronic equipment has promoted the United States、Soviet Union and other countries micro gear motor,Dc gear motor development and production。 With the continuous development of the gear motor industry，More and more industries and enterprises use gear motors，There are also a number of enterprises into the gear motor industry。Current，Micro gear motors in the world,Dc gear motor market，DE、method、The British、beauty、In the、The ROK and other countries
Linear module is a linear transmission device，There are two main ways。One is composed of ball screw and linear guide rail，The other is composed of synchronous belt and synchronous belt wheel。It has a wide range of use，Easy to install，High precision，It is accepted by the majority of users！It eliminates the need to create its own linear motion mechanism。 Linear module（ linear unite）It is a general term for devices that can achieve linear motion in the field of automation industry，Also known as positioning module。Linear modules can be considered as mechanical engineers through the transformation of machinery and mechanical development，Share experiences and exchange knowledge with each other，The result is a universally used intellectual product。 structure： Because different specifications affect the development of different structures，Therefore, it is not possible to unify the structure in the specification of linear modules。However, the structure can be divided into external structure and internal struc
Stepper motorThe operation state is different from that of ordinary motors，It turns step by step with the pulse of the power supply，Its a digital motor。The stepper motor rotates the corresponding number of steps with the number of power pulses supplied，And the Angle of each step is fixed，So the stepper motor is controlled by the number of turns required、Angle，Widely used in CNC machine tools、Automation equipment、Instrumentation and other industries。This section describes the widely used reactive stepping motor。 The reactive stepper motor works by generating torque according to the reluctance property，It follows the principle that the magnetic flux always closes along a path with low magnetoresistance，Torque is formed by magnetic pull。The switched reluctance motor described earlier can also be regarded as stepping operation，Because the rotor rotates at a certain Angle when each group of coil power is switched，Just stop switching and the rotor stops moving，Except the Angle of each step is30The degree of，T
