introduction：INAbearing[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。]Vibration diagnosis technology includes signal acquisition、Three aspects of signal processing and fault identification。 Signal acquisition of vibration generated by rolling bearings，contain1kHzBelow the low frequency vibration and thousands of Hertz or even tens of thousands of Hertz of high frequency vibration。 Therefore, the acquisition of vibration signals is often accelerated

introduction： 1.segregation Uneven distribution of chemical composition and impurities in steel，segregation。Generally will be higher than the average composition，This is called positive segregation，Below average composition，Its called negative segregation。There is macroscopic segregation，Such as regional segregation and micro segregation，Like dendrite segregation，Segregation between crystals。 Segregation in heavy forgings is closely related to ingot segregation，The degree of segregation of the ingot depends on the steel grade、Ingot mould、Smelting quality and pouring conditions are related。Alloying element、Impurity content、Gases in steel all increase the development of segregation。The bigger the ingot，The higher the pouring temperature，The faster the pouring speed，partial

introduction：When designing plastic injection molds,Its design procedures and design points are roughly as follows: 1. Study and analyze product parts drawings,Master the use of plastic partsUse and appearance requirementsAssembly accuracy and determination of allowed gate and flash position.And to understand the plastic variety and its forming process. 2. Select the injection machine specificationsModel number. 3. Production batch according to plastic partsSpecifications of the injection machine and the size of the plastic parts,Determine a mold can produce several plastic parts and position layout scheme. 4. Determine the mold structure scheme.At certainty,Several mold structure forms can be conceived,Make analysis and comparison,Finally decide on an easy system
