New bearing: motor bearing types of symbol meaning

Due to the emission control measures ( Such as using the start-stop system and mixed or taxi operation) The engine in the process of using load increasing, and this new type of bearing can easily carry the high load. Such problems mainly because insulating paint volatilizes out acid formed under fixed temperature and humidity of corrosive substances, the bearing channel after corrosion result in bearing damage. The main consideration the special needs of bearing fit, heavy series =; b— — The matching of the bearing inner ring width, m, b = b - R, B for bearing width, r for inner ring chamfer. Figure outer insulation coating type JA, JB, JAB, JAA; Inner ring insulation JC& emsp; & emsp; Different types of coating insulation performance parameters of the bearing are given in the table below: & amp; emsp; & emsp; Note that you need to do to coating the surface of the insulation bearing ring must be cylindrical, and there can be no oil groove and oil hole. Very applicable to all kinds of precision machinery and mining mill machinery, and the choice of grease is also critical, to choose the suitable for equipment brand, not blindly. Monitoring of grinding process, because of various machinery has different working conditions, the rolling bearing in the load capacity, structure, and puts forward various requirements in such aspects as the use of performance. Usually under cyclic load ring and the shaft, Or shell hole) Suitable persons to interference fit or tighter transition fit, the size of the over surplus quantity of the group in order to do not make suit with shaft hole or the body surface between the crawling phenomenon for the principle. R, choosing proper materials and components for gear pump has reasonable clearance and cooperation in running, the wear resistance is an important performance index of the relevant material, A, oil seal oil is also A common cause of scrap material should be chosen so good oil seal, in processing and assembling at the same time pay attention to the oil seal and with the bushing is strong. If it is not to open, will be more troublesome, was used to prepare grease thickener has two broad categories: soap thickeners ( The fatty acid metal salt) And the soap thickeners ( Hydrocarbons, inorganic and organic) 。 Flour processing machinery maintenance work done will also be able to improve their work efficiency, and reduce the occurrence of fault, flour processing machinery before use, carefully check Inner Mongolia flour processing equipment with or without crushing cavity. When ambient temperature is lower than ℃, available iodine tungsten lamp heating tools such as repair parts for heating, in order to protect coated material, surface temperature is not lower than ℃, facilitate bonding. Equipped with nylon cage bearing can in - °- ° under long-term continuous stable work, work should not be more than hours when °, short peak temperature should not exceed °.
