  • Rolling bearings substitute general rules

    introduction:Rolling 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。]Substitute for,It is generally first selected from a diameter series lower than the diameter series of the original bearing,And the outer diameter of the selected substitute bearing should be the same as that of the original bearing,The inner diameter is larger than the original bearing。This is mainly to consider:(1)Easy processing,Save material;(2

  • Whether internal combustion engine oil and gear oil can be used interchangeably

    introduction:Lubricating oil is generally made of base oil and various additives through a certain process。Internal combustion engines operate under harsh conditions,Internal combustion engine oil is often at high temperatures、Large temperature variation,Easily mixed fuel、Lubrication under conditions of incomplete combustion mixture and other impurities。This requires higher performance of internal combustion engine oil:Such as good wear resistance、Excellent oxidation stability,It is not easy to deteriorate under high temperature conditions,Not easy to gelate、Carbon deposits and other substances;To have good viscosity-temperature properties,So that the oil can maintain a relatively stable viscosity under the condition of large temperature difference。In addition, the internal combustion engine oil also requires a good clean dispersion、Resistance to

  • Assembling FAG imported bearings determines the operating limit principle by external temperature

    introduction: Generally admissibleFAGImported bearing[Imported bearing:Simply put, the import bearing agent refers to the sale of an imported bearing brand。The main brands of imported bearings arenskbearing,ikobearing,fagbearing,Of good quality,Of course, the price is not cheap。]The external temperature of the seat is inferred。However, it is more accurate to measure the temperature of the bearing outer ring directly by using the oil hole。Bearing temperature,It gradually rises from the start of operation,usual1~2The temperature stabilized after hours。If bearings are improperly installed,The temperature will rise sharply,Abnormally high temperature。Causes include excess lubricant、Bearing clearance is too small、Poor installation、Seal friction

  • Rheological properties of plastics

    introduction:Plastic in the molding process,The flow behavior and the microstructure after molding will be affected by the rheological properties of plastics。The rheological properties of some plastics are listed below: Shear viscosity(Shear viscosity):It reflects the ability of plastic melt to obstruct the flow during shear flow。 Yield stress(Yield stress):If the plastic melt is a Binha fluid,Only after the stress exceeds a certain limit,Talent flow。This stress limit is the yield stress。 Tensile viscosity(Extensional viscosity):
