  • Bearing ring super finishing characteristics

    introduction:Superfinishing means under good lubrication conditions,The workpiece rotates at a certain speed,At the same time, fine-grained grinding stone is pressed to the workpiece machining surface with a certain pressure,And a processing method for oscillating motion perpendicular to the rotation direction of the workpiece。It has the following characteristics: 1.Can effectively reduce the ripple degree。Super finishing process,When the arc of the grinding stone in contact with the workpiece is greater than or equal to the wavelength of the workpiece surface waviness,It can ensure that the millstone always acts on the crest of the wave and does not contact the trough,So the crest contact pressure is greater,The convex peaks are removed,This reduces corrugation。 2.Improved ball bearing[bearing

  • Power machinery: saturated steam turbine

    introduction: Steam turbine using saturated steam as fresh steam﹐Also known as wet steam turbine。It is widely used in conventional nuclear power plants(Steam turbine)And nuclear-powered ships﹐It can also be used in geothermal power plants and solar power plants。Compared with conventional large power station turbine of the same power﹐The saturated steam turbine used in nuclear power plant has certain characteristics and requirements。Use saturated steam as admission﹕Generally adopt5~7Mpa of saturated steam。Due to pressure﹑The temperature is lower﹐The amount of available heat given off by the expansion of steam per unit mass in the turbine for work(Enthalpy drop)About half﹐The mass of new steam required per unit of power

  • Analysis of raceway noise of FAG tapered roller bearing

    introduction:Raceway noise is due to tapered roller bearings[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。]When rotating, the rolling element rolls in the raceway and generates a smooth and continuous noise,It attracts attention only when its sound pressure level or tone is extremely high。In fact, the sound energy stimulated by raceway sound is limited,As in normal circumstances,Of high qualityFAGbearing[F
