Bearing pads: bearing 6900 z is what material

With the access to appropriate recommendations; Hysteresis plug symptoms: partial or large welding and guard and deep scratches on the surface of the roller; In this area and lubricant coking; Reasons: improper lubrication of high load and high speed ( The number of lubricant and low viscosity) ； Improper lubrication of high load and low speed ( There is no fluid lubrication film between roller surface and the guard) ； Due to the thermal diffusion. Also installed on the same shaft, the other end bearing and shaft turning laps, let fixed bearing itself automatically find the position is, the influencing factors on the quality of the bearing structure design and advanced at the same time, there will be a long bearing life. Knocked all the master maintenance simply took the horn is to break down, pull down after the horn can be seen clearly above the ball cage universal joint, above the circle has almost all of the tooth is rust, no wonder the mesh so fast. It is not completely rust, but the salt, the effect of acid and alkali, match the mm, inside the compressor axle sleeve tooth within the cylinder and outer cylinder of turboshaft to B. Lines to the generator temperature sensors, generator fan, heater wire, carbon brush to feedback, rotor terminal all removed, all line marking. Restored, can be seen from the whole repair process, sauvy technology to the whole process is very simple and quick fix, without tedious process steps and a large number of tools, but many details need to strictly control the repair process. Heilongjiang big bending axis accident of a certain power plant in heilongjiang province motor maintenance staff years of a certain power plant in # machine processing exciter commutation carbon brush a blaze defect, due process, technical level is not high, cause the ring of fire, lead to # generator field loss, active load swing sharply, speed regulating valve is out of control, buried under the ruin for the accident. Crack damage of bearing parts crack is caused by overload or cyclic load stress, smelting technology and processing technology can also cause cracks, in addition to the cracks caused by inclusions and oxide, cracks caused by smelting and processing technology, can't enter the subsequent machining process. Diamond dressing of grinding wheel is not sharp or quality is bad; , in order to solve the problem of oil spill, technicians have come up with a variety of way, but didn't get the ideal effect. The bearing in cans containing oil, engine oil barrels outside with hot water or flame heating, heating process requirement of the oil temperature control in ℃ ~ ℃, not more than ℃, more can't more than ℃. Bearing according to its structure shape ( Such as presence of loading slot, presence of inner and outer ring and the shape of a ring, the structure of the guard, even the presence of cage, etc. ) It can be divided into various types of structure. Contact Angle ( Nominal contact Angle) con- Methyl amino acetonitrile tactan - Methyl amino acetonitrile gle ( n - Methyl amino acetonitrile omin - Methyl amino acetonitrile alcon - Methyl amino acetonitrile tactan - Methyl amino acetonitrile gle) Perpendicular to the plane of the bearing axis ( Radial plane) And by the bearing ring or washer is passed to the function of rolling body line ( Nominal action line) The Angle between the.
