introduction：bearing[bearing:bearing（“Bearing”，Japanese person“Axial receptor”）It is a part that holds and reduces the friction coefficient of load during mechanical transmission。Can also be said，When other parts move relative to each other on the shaft，A device used to reduce the coefficient of friction during power transmission and to keep the center of the shaft fixed。]Whether the installation is correct，Affect the accuracy、Life span、property。therefore，The design and assembly department should fully study the installation of bearings。It is expected to be installed according to operating standards。The operating standard items are usually as follows (1）Clean bearings and bearing related parts bearings

introduction：one、Process adaptability principle The principle of process adaptability mainly means that the function of the selected CNC equipment must adapt to the shape and size of the machined parts、Dimensional accuracy and production timing requirements。 Shape size adaptability。The selected CNC equipment must be able to adapt to the shape and size requirements of a reasonable group of machined parts。This should be done on the basis of the process analysis of the machined part，The important thing to be careful of here is to prevent costly costs due to redundant functions。 Machining accuracy adaptability。The selected CNC equipment must meet the accuracy requirements of the group of parts being machined。In order to ensure that the machining accuracy is not out of whack，Must examine production

introduction：FAGbearing[FAGbearing:The main shaft bearing is made of a solid inner ring、Outer ring、The ball、And a single row angular contact ball bearing consisting of a cage assembly with a solid window cage。]It is the main vibration source which is difficult to control the vibrating screen，Because the vibrating screen relies on a large incentive force to maintain the limit speed and friction coefficient of the working bearing，Therefore, the radial force of the outer spherical bearing is very large，Vibrating screen in the working process，Large exciting force will cause elastic vibration of bearing system。If poorly lubricated，There will be greater friction to make the bearing temperature rise too high，Excessive thermal expansion，The radial clearance is significantly reduced，This in turn increases friction，wen

introduction：The principle of linear fixed gear transmission is simple，In a pair of meshing gears，There is a gear as a driving wheel，Power comes from it，The other gear serves as the driving wheel，Power comes out of it。There are also gears that serve only as transit stations，One side engages with the drive wheel，The other side engages the driven wheel，Power flows through it，This gear is called an idler。 In a gear system containing planetary gears，The situation is different。Because of the planetary shelf，That is to say，There can be three axes of rotation to allow power input/exportation，You can also use something like a clutch or a brake，Limit one of these when needed

introduction：Reducer industry report one、 Reducer basic introduction definition：The reducer is a power transmission mechanism，Speed converters using gears，Switch machine（motor）The number of turns slows down to the desired number of turns，And get a larger torque mechanism。 Working principle：The reducer is generally used for transmission equipment with low speed and high torque，Knob motor、The power of the internal combustion engine or other high-speed operation is decelerated by the small number of teeth on the input brake shaft of the reducer meshing the large gear on the output shaft，The ordinary reducer will also have several pairs of the same principle gear to achieve the ideal deceleration effect

introduction： 1. Choice of surface grinding wheel When grinding with the circumference of a grinding wheel，Generally use ceramic bond parallel grinding wheel，The particle size is...F36~F60，Hardness inH~Lamong。 When grinding with the end face of a grinding wheel，Due to the large contact area，Chip removal difficulty，febrile，Therefore, most of the cylindrical or inserted grinding wheels using resin bond，The particle size is...F20~F36，Hardness inJ~Lamong。 2. Selection of grinding amount （1）Grinding wheel speed （2）Longitudinal feed of table
