The cause of damage to the ultimate speed of rolling bearing

In general, the correct use of rolling bearings can reach tired life.But if the onset of accidental early injury, it can no longer be used.Unlike fatigue, this early injury is called a defect or event.More due to equipment, use, lubrication on the consideration of improper, from the external invasion of foreign matter or about the shaft, bearing seat of the lack of research and so on.Damage to rolling bearings, such as chafing on the rim of the ring of www.sxat-bearing.comr, may be caused by a lack of lubricant, improper trademark, defective oil supply and discharge scheme, foreign body invasion, wrong bearing equipment or excessive shaft deflection, or may be caused by all of the above reasons.Therefore, only query bearing damage, it is difficult to know the actual cause of damage.However, if on the basis of fully understanding the use of the bearing machine, working conditions and its peripheral scheme, make clear the situation before and after the occurrence of defects, and then contact the bearing damage situation and a variety of related reasons for analysis, can prevent similar defects again.Representative bearing damage causes and countermeasures.Even the most advanced modern manufacturing skills are used to process rolling bearing parts.Query how its reading changes with the preload.Pre-tightening has its unfortunate side, as we all know.The working surface will always be kept in the dial meter head on the bearing face or the appropriate part of the shaft.1. Bearing scheme and service conditions.Different schemes are suitable for different conditions of execution;Automobile bearing parts program is not the same as its processing skills are not the same, also affect its quality.Therefore, we should develop new program commodities, with the habit of different service conditions, and can be used in rolling bearings on the application of the specification of the appropriate service conditions or functions, so as to be the customer's choice.2. Strengthen skills research, improve processing skills, trek processing quality, reduce the possibility of defects in processing.Such as in the heat treatment, for larger varieties inside and outside the ring, as far as possible with the lower and middle quenching heating temperature, the gas extension insulation time, to tri alloy concentration, increase the martensite fracture strength, and under the premise of ensuring quality choose a higher tempering temperature to enhance the impact toughness of the workpiece.3. Improve the processing monitoring method and promote the improvement of processing quality.For example, it can improve the monitoring of the curvature direction of the circulation path, improve the overall function of the trudge vehicle bearing equipment, and improve the rolling bearing operation.
