Bearing procurement: the car bearing is free maintenance

Have hobby friend mindset on mechanical bearings, because for different occasions, bearing also has two categories, one for sliding bearing for rolling bearing, we often see in life is to rolling bearing, trust friends, when I was a child often played rolling bearing! We don't have any toys, little poor, is interested in the rolling bearing steel ball inside. & emsp; & emsp; Wind turbines have fire accident, there are also abroad, the unit in the replacement of generator, coupling, coupling cover and destroyed part of the circuit and sensors, connected to the grid. This is called needle roller, this USES the curve groove groove ball bearing, through the bearing can put the existing rotary motion into reciprocating linear motion bearings. In theory, every tolerance grade linear bearing can choose each group of clearance, clearance group's choice but must according to the specific working conditions, use circumstance temperature, load and configuration of linear bearing situations to choose, to achieve the precision of the linear bearing capability. Take the bearing of each measurement point of the crest factor of great value as the bearing acceleration wave factor, summary, bearing is highly sophisticated and core components, be sure to use according to the parameters. Reappearance covered surface covered surface traces of the main reason is because of the grinding wheel cutting edge is not sharp, 'eating up' occur when grinding, the vibration is larger. Grinding wheel dressing time finishing is not good; High carbon chromium bearing steel GCr is one of the world production of bearing steel, carbon Wc about %, Wcr for chromium content. Bearing should also be regular cleaning, keep clean, on the basis of choosing reasonable heat resistance and oxidation resistance on the still need to pay attention to the extreme pressure lubrication grease, pay attention to daily maintenance. Rolling bearing has become the main mechanical bearing type, more and more widely applied, forming technology, metal crystal solidification, precision, good surface quality and wear-resisting. A common cause of bearing temperature is too high, and large vibration: may be due to the coupling is not accord with standard of process, find rotor unbalance activity, poor foundation rigidity and the anchor, rotating stall and surge. Preventive maintenance of equipment, operation and peripheral parts replaced was removed when bearing inspection, judge can use or using again as a condition of good from bad. Using sauvy repair technology at the same time can be confirmed after repair % face with these requirements, in recent times larger than the area of new parts, the better to meet the requirement of stress, and nearly use effect.
