introduction：When selecting a model，Firstly, according to the tooth shape model of synchronous belt and synchronous wheel，And the pitch of synchronous belt and synchronous wheel and other relevant meshing parameters，Determine the number of teeth of the synchronous wheel、Pitch diameter and structure。 The calculation of the number of teeth and diameter of synchronous wheel is mainly to determine the number of teeth of small synchronous wheel first，Then, according to the transmission ratio of the synchronous wheel transmission system, the number of teeth of the large synchronous wheel is determined。 In order to ensure the service life of the synchronous wheel，The diameter of the small synchronous wheel should be greater than the minimum allowable bending diameter of the synchronous wheel，Then convert the data to the minimum number of teeth of the synchronous wheel。As long as the structure and cost allow，Then consider the service life of the synchronization belt，Small synchronous wheel

introduction：There are quite a few machines for processing small industrial parts。 In particular, some small parts requiring high precision require some high-end equipment to process。 In the precision machining industry，The process of changing the shape and size of a workpiece with a machine tool is called machining。 The so-called high precision machining refers to the high precision marked on the production and processing drawings，This requires sophisticated processing equipment to complete。Precision processing plant precision processing equipment mainly：lathe、Milling machine、Fast-moving wire/Slow wire、Machining center、Edm and other precision machine tools。CNC machining center machine tool itself has a high precision，Can be machined with high precision、

introduction：Metal scales have the following characteristics： （1）The processing of metal ruler blank is easier than that of glass ruler，Especially the long ruler。However, it is much more difficult to obtain a very high surface finish than a glass ruler； （2）The linear expansion coefficient of the metal ruler is close to the whole instrument and the workpiece to be measured，In that respect，The instrument using metal ruler has lower requirements on temperature conditions in use。 （3）The cross section of the metal ruler can be made into more complex shapes，To reduce bending deformation。The scale will bend and deform under its own weight or external force，Resulting in error，The error is closely related to the size and shape of the scale section

introduction：A flat key is a key with two sides as its working surfaces，Torque is transmitted by squeezing the sides of keys and keyways。Flat keys are divided into ordinary flat keys、There are three types of thin flat keys and guided flat keys。 Plain flat bond is good for neutral，High positioning accuracy，And easy to disassemble，However, the axial fixation of the parts on the shaft cannot be realized，For high speed shafts or shafts that withstand shock and variable loads。Thin flat keys are used for thin-walled structures and where little torque is transmitted。The guided flat key is used to fasten the key to the shaft with screws，It is used when the parts on the shaft do not move much along the shaft。1、Matching size of flat key connection key、Shaft keyway、Hub keyway width ruler

introduction：Shaft retaining ring is a kind of mounting on the groove shaft，Holes used to hold parts move in the direction，The inner diameter of this type of ring is slightly smaller than the shaft diameter of the assembly。 classificationally，Shaft retaining ring is divided intoAType sumBtype。The specific differences between the two are as follows： 1. Different market applications：AYamatoBIts all on the market，The difference lies in the shape of the mounting holes，AThe type is an arc transition，whileBType is a right Angle transition。 2. The hardness is different before and after heat treatment：They also have different hardness after heat treatment，BThe heat treatment hardness of the type is slightly higherAtype。The inner diameter ratio of this type of retaining ring is fitted to the shaft

introduction：Spring is a kind of elastic element widely used in mechanical and electronic industry，The spring can produce large elastic deformation when it is loaded，And convert mechanical work or kinetic energy into deformation energy，After unloading, the deformation of the spring disappears and returns to the original state，At the same time, the deformation energy is converted into mechanical work or kinetic energy。 The ratio of the load to the deformation of the spring is called the spring stiffness，The greater the stiffness，The stiffer the spring。 Action of spring： Cushioning and damping。Like a car、Damping spring under the train box，Various buffer springs, etc； Control the movement of the mechanism。For example, valve springs in internal combustion engines，
