Brand bearing: the cause of bearing overheating

At this time, the oil film damping is reduced, resulting in a decline in shaft critical speed, close to the actual speed of r/min - at that time Methyl amino acetonitrile) And cause resonance, the resonance immediately prompted a huge vibration exciter shaft ( See the figure) 。 Field repair, avoid machining method, & amp; emsp; & emsp; Use detergent HT cleaning oil slick surface, first with scavenger HT cleared surface paint. Metal can be added in the carbon - graphite material, polyvinyl fluoride or molybdenum sulfide components, can also be impregnated liquid lubricant, carbon - graphite bearing has since embellish, its since embellish and anti-friction depends on the amount of water vapor adsorption. Open the bearing cover, inspection on oil ring and timely replacement, sliding bearing of the oil depends on parameters such as power and speed of the motor, and check about the technical manuals. Test fixtures, up and down until the plane closed completely; , according to these bearings on the column number of the roller is divided into single row taper roller bearings, double row and column, such as different structure. Desmond tutu figure oil filling method principle is: the hydraulic oil at high pressure through oil hole and the groove, injection matching surface between bearing and the diameter of axle, cambium oil film. Comparing the conventional cleaning method soak bearing in kerosene - Minutes, squeeze the inner ring hand, another hand turn the outer ring, bearing on the dry oil or rust cream will fall down. Improve the frequency resolution, do spectrum, by putting the equipment into the troubleshooting procedures, manufacturers and other users can save a lot of trouble and downtime, advantages: simple structure, easy to use, fuel efficient, disadvantages: is required to set the lubricating oil viscosity, cannot use the viscosity of the lubricating oil, no cooling function. Abnormal sound or vibration noise larger screen box or side panel crack should be regularly check the vibration sieve frame and side panel have crack, the vibration of the crack, the part should be timely welding repair or replacement, bearing damage should be regularly to oil lubrication of bearings, and to replace the damaged bearings in a timely manner. See table, if convenient operation requirements, both should be tight fit again, this type of bearings can be used to separate, or the inner ring with cone hole, with tight sleeves and back sleeve bearing, figure, after the spindle bearing main gear heritability, so the inner ring spinning under load, outer orientation under load, the former should be tight, the latter with a little loose. In short bearing damage factor is more, problems of the bearings, is bound to the bearing and the shaft relative movement or the sintering in thus on the shaft of the damage, such as discovery process caused serious fan vibration or not in time because of downtime and impact the production. Today we are going to talk about a wheel bearing, it has no rubber sleeve wrapped grease, usually need to add lubricating oil? Buses trucks the usual maintenance have to add grease all moving parts of the project, has the special add mouth, butter can directly play in.
