Rolling bearing, roller bearing is the most commonly used precision grade

LED fog lights on both sides of the area using the same sample into the gas hole design, more obvious the radical, in addition to this aspect, the car on the side lines stereo sense is very strong, the side of the window, and you can see behind the mirror using the black colour adornment to adorn, have the feeling of movement. The stress relieving the stress relieving (also called low temperature annealing Or high temperature tempering) , the annealing is mainly used for casting, forging, welding parts, rolling, the residual stress of cold-drawn pieces, etc. Irregular change bearing different sound: cleaning related parts, large vibration coupling to align technology difference is not in conformity with the requirements, for example, dynamic and static unbalance rotor, poor foundation rigidity and the anchor, rotating stall and surge. & emsp; & emsp; FAG bearing of insulation coating by plasma spraying technology, can make a very solid oxide coating adhesion on the substrate material. Testing on automobile wheel bearing, actually not complex, here, according to understand, to share knowledge about bearing lubricating oil and grease. Bearing structure form selection of rolling bearing housing, unless you have special need, much like the integral structure, split bearing just have trouble in the assembly, or on the advantages of convenient assembly become main consideration when using, but IT cannot be applied to tight fit or with more precision, such as K and tighter fit than K, and tolerance grade for IT or more precision of hole, are not allowed to adopt split housings. According to incomplete statistics, in the past five years, the domestic general polycarbonate, polyoxymethylene, polyamide, thermoplastic resin, modified polyphenyl ether and so on five big engineering plastics and market demand to keep straight. Steel ball in the rotating friction resistance, which can obtain high precision smooth movement structure working process of the linear bearing is within the outer ring is equipped with steel ball cage, cage containing multiple ball, ball as an infinite loop. Release bearing ring there are many reasons, on the diesel engine adopts sliding bearing, main bearing parts such as bearing made of subdivision, two and a half after the split like tiles, so it is also referred to as the bearing shell. At work, the elastic force in the flange and the seal (PT line suite of friction should be greater than the pressure differential DP flange on the flange end face and the shaft sleeve worse at end A friction, make the flange does not rotate with the shaft sleeve, just between the flange face and A relative sliding, so will slide oil seal leakage, in order to generate axial elastic force and easy to assemble, flange counterpart in circular aperture, lubricating oil will be the gap from leakage, therefore, when the flange seal device is used, A need to flange, and the counterpart of the flange gap shall be staggered °. & emsp; & emsp; The accident reappearance and cause analysis & amp; emsp; & emsp; In the accident, unit are in a state of full power, generator bearing damaged, card before death, when bearing fault, first the damaged bearing cage, bearing between the inner and outer ring friction heat is serious, this is interference fit, due to the rapid thermal expansion, caused between the bearing inner ring and generator shaft resistance is reduced, and generate mutual sliding, friction produces a lot of heat. First the actual size of field measurement axis, once again confirm the uneven wear size; By lathe turning tool, remove surface impurities and repair, make its unilateral depth is greater than.
