Ball bearing: sonata eight start engine bearing loud

Combustion furnace waste heat utilization has reached a very high degree, and empty - burner structure optimization The strict control of fuel ratio under the premise of the reasonable combustion, reduce NOX and CO to the lower limit; Using gas carburizing, carbonitriding and vacuum heat treatment technology instead of salt bath treatment to reduce FeiYan and CN - Content of water pollution; With water soluble synthetic quenching oil instead of part of the quenching oil, using biodegradable vegetable oil instead of part of the mineral oil to reduce the oil pollution. Question tabled reason and solution: water pump motor power trip if the matching power suddenly protector are consistent with the water pump motor, under normal circumstances, the protector is not trip. Coupling is not good for the most equipment operation will also cause bearing heating or failure of the input shaft is connected by shaft coupling and power, so when the assembly must be alignment of coupling, drive shaft and driven shaft on the coaxial line. Is responsible for turning in the inside of the bearing place is different also, low speed of this it is mainly used in the circular, cylindrical and conical rotor, the high-speed bearing is bearing shell. For high load high speed of spherical roller bearing, adjust clearance, must consider the effect of temperature on the axial clearance, clearance reduction is estimated, will cause the temperature rise, that is to say, the axial clearance to appropriately adjust the big dots, too. Machining surface roughness or worn to choose lubricating oil of high viscosity, drops of oil varies with oil viscosity and bearing clearance and the oil hole position different significant changes. Enterprise equipment problems and analysis equipment parameters: the ball mill mm shaft diameter, bearing width mm, bearing type mm/CA/W bearing a unilateral wear; Equipment problem: long running process, due to the bearing life cycle is too long, the bearing itself appear wear away, clearance is too large, medium oil film lubrication process to protect the bearing lubrication, at the same time, seal damage internal material dust into the bearing, bearing rolling friction increases, the normal operation of the serious influence bearing, lead to bearing operating temperature is too high, cause bearing sintering lock, and progress lead to bearing inner ring and relative rotation axis. For novartis in induction heater, bearing is a secondary coil short-circuit single-turn, under the condition of low voltage by large current, by making a lot of heat. GS, ten set-contained insert ball bearings are of spherical ball bearing by the two sides with a seal of outer spherical ball bearing and casting ( Or steel plate stamping) Bearing seat. Item, hardness, hardness is the key to ascertain the bearing quality guidelines on contact fatigue strength, wear resistance, elastic limit self-lubricating bearings have indirect effects, the masses of users generally reflect not only fuel-efficient inlaid bearing, energy saving, and its working life is longer than ordinary sliding bearing. , this is due to the constant pressure preload count increases while the inner ring contact load is reduced, but at the same time make the inner ring of contact Angle decreases, and they work together to make bearing radial stiffness significantly increased, and the axial stiffness and Angle decreases slightly. Medium-sized motor, the use of the non-stop refueling bearing assembly structure, the composition of the rolling bearings rolling bearing, the inner ring and outer ring, rolling element and cage, the refueling device than from bearing cover oiling device effect is much better, use a toothbrush first brush away dirt on the surface of the perlin, do this also, not bad.
