The first thing we need to know：The chain and sprocket must be the corresponding model！Give an example：40Chain arrangement40Sprocket wheel(The number of teeth varies according to need)。Need attention：There are two main lines of productsAwithBThere is a slight difference in size between the two！We know from the above，Chain and sprocket can not be casually paired，Must be selected according to the relevant parameters。The following Feng Ye engineer to introduce to you about the sprocket and chain product knowledge：A sprocket is a solid or spoked gear，Mesh with a roller chain to transmit motion or power。Sprockets are widely used in chemical industry、Textile machinery、Food processing、instrument、Oil and other industries
First of all, we need to know what products are linear bearings and oil-free bushings to better analyze the differences between the two！1、Linear bearing：Its 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 minimal 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。2、Oil-free bushing：It is a kind of high force brass bearing with oil gushing as lubrication。The product has a traditional tin bronze bearing function，After adopting high force brass，thereofH
Cross slide coupling also known as metal slide coupling，The slider is circular，Made of steel or wear-resistant alloy，Suitable for low speed，Transmission with high torque。Advantages of cross slide couplings：1、The main shaft sleeve is made of aluminum alloy,Light size2、The center cross slider is available in a variety of different colors3、Easy to install、maintenance-free、It can resist oil, corrosion and electrical insulation4、Simple structure with high torque，High rigidity，High sensitivity coupling5、Tolerates large radial and axial deviations6、Absorb the higher transmission torque7、Long life，Safe and reliable performance8、Not suitable for high-speed transmission9、Production technology:Finished turning parts
The miniature linear guide rail is one kind of guide rail，Its guide rail size is small、Light weight，Especially suitable for miniaturized equipment。Sliding block、 Guide rail materials are available in stainless steel and alloy steel。Stainless steel linear guide rail，Inclusion slider、Rails and other metal accessories such as steel balls、retainer，All are made of stainless steel，It has anti-rust properties。Gothic four-point contact design is adopted， Can withstand loads in all directions，Have strong rigidity，High precision characteristic。Has steel ball retainer design，Interchangeability when accuracy permits。Because of its product characteristics, many industries need to use miniature linear guides，Make the work more efficient，
The function of the support seat The support seat is the bearing fixing seat that connects the lead screw and the motor，It is a finished product of the shaft end of standard ball screw，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。Especially inEK6、8The subminiature type，Equipped with contact angles developed for ultra-small ball screws45°The ultra-small angular contact ball bearing，High rigidity can be obtained、High precision stable rotation。Support seat structure1、Support seats are available8models，On standard ball screw stock
I believe that many engineers who do mechanical machine tools and equipment are no strangers，This is a kind of rolling guide on the machine，Infinite rolling cycle between the slide block and the guide rail by the steel ball，The load platform can easily move linearly along the guide rail with high precision。However, the inferior Yintai guide rail will do great direct harm to our machine，So how do we prevent this from happening？Dre will tell you today，How to avoid damage to equipment caused by inferior guide rails！If you want to know how to avoid it, you must first understand the product Yintai Guide rail，Know one of its product characteristics in order to better avoid the selection of inferior Yintai guide
In recent years，Linear guides are widely used in industrial and manufacturing fields，Today the accuracy is getting higher and higher，Live longer and longer，Easy to maintain，So the future trend is clear。In that way，What are the performance characteristics of linear guide rails?1、Automatic aligning capability from circular groovesDF(45-°45)°assembly，During installation，By elastic deformation of steel ball and transfer of contact point，Even if the mounting surface is somewhat deviated，It can also be absorbed inside the rail slider，Produce the effect of automatic aligning ability and obtain smooth motion with high accuracy and stability。2、With interchangeability due to strict control of manufacturing accuracy，
In the process of striving, one will always be confused, confused about the future career path, confused about the difficulties encountered in the workplace, and struggling in the confusion and confusion at this time, it is the greatest luck if someone offers a hand and that person may be very ordinary but can guide the key moment like a straight light axis——Linear optical shaft Simple design best performance low maintenance costs Rugged materials with the guiding role of plain bearings enable the implementation of linear movement of course，The teacher of life is not the same feeling is the same, just like the linear bearing category is different, but it is the existence of ordinary linear optical shaft materials and heat treatment
Pneumatic components are a form of power transmission，A component in which work is done by the pressure or force generated by the expansion of a gas，That is, machine parts that convert the elastic energy of compressed air into kinetic energy。Pneumatic components are often used in cylinders、Air motor、Steam engines and other machinery and production lines。Pneumatic components are not only easy to operate，It also has the following advantages：1、Pneumatic device has simple structure、portability，Medium is air，Compared to the hydraulic medium，non-combustible，Therefore, it is safer to use；2、The working medium is inexhaustible air、The air itself costs nothing，Simple exhaust treatment，Do not pollute the environment，And low cost；3、Due to the
Four basic knowledge of linear optical axis，As long as3In minutes you can easily grasp the linear optical shaft is equipped with guided plain bearings，An automatic transmission part that makes it move in a straight line。And the realization of these linear motion systems，Here are the conditions that must be met：Simple design；The best execution ability；Low cost of maintenance；Use a rigorous selection of strong and durable materials；Accurate outside diameter dimensions；High frequency heat treatment；roundness；True straightness and surface treatment, etc。The most common types of shafts are crankshafts、Three kinds of straight shaft and flexible shaft，Because there are many kinds of straight axes，So here is an example to illustrate：The straight axis can be divided into：The mandrel is used to support the rotating zero
