Bearing steel ball: what are some of the bearing outer diameter of 140

To sum up, sauvy crane industrial carbon nano polymer materials to repair the spindle wear under repair with high efficiency, which can realize the online repair, machine repair, etc. , comprehensive repair cost is low, to the enterprise equipment maintenance maintenance provides a powerful solution, greatly reduce the production cost of enterprises. Bearing wear online repair using sauvy technology concrete operation process is as follows: surface baked oil: oil using acetylene oxygen for baking, operation time control between the minute to minute; Baked oil bearing processing surface polishing: use polishing machine burnish of surface roughness, clean, improve sauvy carbon nano polymer SDH cohesive force. Under the environment of higher temperature should choose sodium based or compound calcium base grease, of course, consider the bearing capacity and fatigue life of bearing, will no longer be discussed here. Fully understand the working conditions of failure bearings, using process and manufacturing quality, etc. , the concrete content includes: the host load, speed, working condition of bearing design working conditions. Open the window if listen to the sound came from outside; After the speed ( Hum is larger) Put stall in space vehicles glide, observe whether the noise from the engine, if the neutral taxiing hum no change that is there is something wrong with the wheel bearing mostly; Temporary parking, check the car axle temperature is normal, the method is: with the hand touch next wheel, respectively, under the general feeling whether they cause ( Brake shoe, normal clearance, the temperature of the front and rear wheels is a gap, the front wheel to high) , if feel difference may continue to slow traffic to the pit; Lift the car rises ( Loosen the hand brake, idling) before , there is no elevator can use jacks one at a time when rising wheels, human rapidly rotating wheel, respectively when there are problems of axle, it make a sound, axle and other no samples, using this method can easily distinguish which axle is have a problem. Pulsating magnetic flux in the shaft, bearing and casing formation of the induced voltage in the circuit, and the shaft current flows through the circuit, shaft and sliding bearing surface, or rolling bearings and bearing sleeve surface damage, surface to increase the friction and heat, operating performance deterioration of rolling bearings, etc. The metamorphic layer inevitably affects the change of the surface residual stress, while the spindle is the core of the press parts, main shaft bearing repair, is the hot topic in enterprise is very straight. External material may lead to wear and tear 'particle pollution and debris of bearing face precautions: wear, abrasion and sag to remove particles and debris, replacement of lubricants, check the sealing system. Which plunge cut or ball in front of the working procedure, the type of the retainers are: low carbon steel/stainless steel cage, bakelite/plastic ( Nylon) Cage, bronze/brass/aluminium alloy cage, etc. Coarse-grained grinding wheel just trimmed when grinding grain is easier to fall off; , correct installation bearing is very important, but always easy running deviation in the actual operation, problems emerge in endlessly. When enterprise through the network learned sauvy carbon and online after the repair technology of polymer materials, through technical understanding of communication and related enterprise case, the repair effect of the enterprise from the aspects of technology of doubt, and determine the online repair issues. Grinding measuring need higher assembly, ensure the clearance, the assembled shaft can be less than, to test the bearing operation, ensure to meet the scope of the standard and complete assembly.
