The design of the bearing axis: bearing 88508 a what kind

Form: according to the tank to the points - — Along the axial direction, the circumferential, oblique and spiral wound, sliding bearing is possible cavitation erosion, erosion, fluid and micro wear failure forms, etc. Then a good bearing and bearing assembly on the shaft, pushed to the required location for installation, fixed bolts do not tighten the bearing seat, to make bearing coat in bearing internal energy. Repair welding machining process itself is easy to make shaft surface local produce thermal stress, cause the hidden trouble of the broken shaft, repair welding and machining process need to spend a lot of manpower and time to disassembly, transport and installation of equipment, the repair time is longer, synthesis of the high cost of repair, long-term stop production will also be a lot of economic loss caused to the enterprise. Ring was magnetized areas have knock against the surface of outer diameter for produce plastic deformation and cold work hardening, the formation of local leakage magnetic field, magnetic powder particles was adsorption and aggregation form leakage magnetic field of magnetic mark, when the surface of the knock against injury, cut was continued after grinding, although naked eye no obvious trace knock against, but because of its surface residual internal stress is not completely disappear, the region will still form a weak leakage magnetic field and magnetic particles adsorption, the magnetic mark belongs to the magnetic mark, related magnetic image morphology as shown. I think this is only a dare to fixed with single bolt tire models, basic don't have to change in a former life, many models for some vehicle weight is a big car, use the mileage is relatively small. These special operating conditions is, when the rolling surface ( Track and rolling piece) By the lubricating oil film effectively separated and limiting pollutants may cause surface damage. Carbide liquid chromatography after longitudinal sample times magnified observation; Carbides band in longitudinal sample times and times combined with observation, according to the evaluation of carbide aggregation degree, size and shape; Carbide network after the transverse magnification observation. Require grease, therefore, has the strong adhesion, can firmly stick on the surface of parts, parts on rolling lubrication bearing, the rest of the stored in the sealed bearing internal space. Crossed, shape precision forging process flow to annealing, coarse car - conditioning - semi finished car to finish turning, quenching and tempering to coarse grinding, low temperature aging ( High precision axis) To fine grinding, inspection. Is the core part of a centrifugal pump impeller, its speed high output force, guide vane pump: water out of the impeller, into its set of guide vane outside, after entering junior or into the outlet pipe. Rolling mill bearing lubrication rolling machine of roller bearing, ever rolled machine adopts self-aligning spherical roller bearing, in order to meet the work of the heart and carrying big extrusion. Should choose small flash point high carbon content of lubricating oil temperature is too high, the bottom diameter (mm screw mm） L = mm screw length L E = = mm nut installation size, because grease are half solid lubricant, the poor liquidity, will spray lubrication oil atomizing spray on the surface of the friction, lubrication method, suitable for high speed bearing.
