Rolling bearing grease: gcr15 bearing steel daqo summary to share knowledge

Bearing steel below according to understand, summed up the relevant rolling bearings commonly used the use of various materials bearing steel performance, mainly has the following kinds: GCr GCr bearing steel bearing steel is an alloy content less, has a good performance, wide application of high carbon chromium bearing steel. Such damage progress, can make the tiny crack increment and cover on the raceway, form the so-called pitting, the pitting progress again to expand and connect appear on the surface of the fatigue spalling. MP— — Brass solid cage, in addition, when the heat treatment quenching temperature is too high and cause overheating parts of the organization, coarse grains, residual austenite size, mesh and more massive particles. Turbine and generator rotor is supported by bearings, the vibration of the rotor is bound to be passed to the bearing, so both the existence of fixed contact, including amplitude, phase, frequency, etc. Oil operation, can be in the mating surfaces, makes the company bearing pads, material is steel, models for MCFen - Methyl amino acetonitrile dplate, complete gasket and fracture morphology is shown in figure. Fan box is a high quality of ventilation and smoke exhaust equipment, it is composed of many small parts, each widget are indispensable parts for fan box, fan box has several important components are in the process of daily maintenance to be more careful. Bearing installation, should force uniform, not hammer, remove the interference fit ring, can only add tension on the ring, not by drawing roller ring. Row cylindrical roller bearings + thrust bearing cylindrical roller bearing inside diameter and the roll neck with tight fit, bear radial force, has a large load capacity, high limit speed, high precision, inside and outside the ring can be separated and interchangeable, easy processing, low production cost, easy installation and disassembly, etc; Thrust bearing axial force, concrete structure could be selected according to the characteristics of the rolling mill to go. Analysis: electric lubrication pump oil outlet side often appear only unilateral oil even without oil, each pump working condition will cause the quantity of oil is normal or not. Mechanical spindle common faults of maintenance treatment: fever, rotating precision degradation failure phenomenon: the low machining precision of workpiece hole, cylindricity is very poor, spindle fever quickly, processing noise is very large. Only in this way there is! Mechanics teacher introduction, bearing inner ring in the process of installation and repair of bearing a compacted fill formed between and make sure they have the extra material being squeezed out. Sauvy carbon nano polymer field repair hydrogen compressor main shaft bearing wear: the car wheel bearing are maintenance-free, normal car use to scrap all need not tube.
