Bearing parts in the high-speed operation, inadequate lubrication and lubrication failure condition, the direct contact between the metal is the most likely cause of the adhesion wear. To prevent or reduce the effective method of adhesion wear is thick film lubrication, the friction pair does not contact, or change the physical and chemical characteristics of the contact surface, making it less likely to stick. Some thrust ball bearing parts using surface phosphating or blueing, forming a layer of compounds on the surface of metal, avoid direct contact between the metal, can effectively reduce or even avoid the adhesion wear. If the surface nitriding, boronizing, deposition and ion implantation. The surface hardness and difficult to yield, is also very effective in reducing the adhesion wear. If the use of sulfur and nitrogen for infiltration, sulfonitriding has effect on reducing the adhesion probability matching between material and increase the surface hardness, and thus to reduce the adhesion wear effect is obvious
Contact fatigue wear is a common failure mode of wear of the thrust ball bearing. Quality steel metallurgy and heat treatment on the fatigue wear performance of great quality, through the use of advanced metallurgy and proper heat treatment method can improve experiment proved that: in a certain range of hardness, surface strengthening method to improve surface hardness can also improve the material for most bearing steel for quenching hardening steel. Practice has proved, in abrasive wear conditions, there is a linear relationship between the material wear resistance and hardness of materials. In the impact load is small, the hardness can be used as the material basis for judging the wear resistance. When the impact load to a certain value, in addition to outside must consider the impact of high hardness and strength and toughness on wear resistance. For high carbon chromium bearing steel, carbide in the matrix composition, types, characteristics, size, number and distribution of all have impact on the wear resistance, the effects of matrix carbon mass fraction and the maximum amount of carbide. In the surface strengthening technology, sometimes is used to increase the fraction of the surface carbon content or method of generating high hardness compound dispersed to improve the surface wear resistance. For example, bearing parts of carburizing and surface carbonization processing etc..
Work and life of the lubrication of the bearing has important effect. Grease is made of base oil, thickening agent and additive. Performance grease base oil mainly by the decision. Generally the low viscosity base oil used in low temperature, high speed; high - viscosity for high temperature, high load.
Thickening is also related to lubrication performance, thickening of the water resistance of the water - resistance grease decide. In principle, grease mix different brands, but, even with the grease thickener, also because of the different additives adversely affect each other. Thrust ball bearing surface coated with anti-rust oil, must be carefully cleaned with clean gasoline or kerosene, lubricating oil and then coated with clean quality or high temperature can be installed. Sealed bearing without cleaning and oiling.
After bearing installed if not carefully tuned straightening can lead to bearing subjected to additional loads friction and vibration. These may accelerate fatigue and reduced bearing service life and may damage the lifespan of the machine parts. In addition, vibration and friction may increase significantly increased energy consumption and premature failure risk.
During use to regular monitoring such as vibration and noise temperature measurements on the basic external conditions thrust ball bearing operation. These regular checks for early detection of potential problems and prevent the emergence of beat all machine halt, make production plans to improve plant productivity and efficiency.
In the process of bearings require proper lubrication once again, perfect its performance. Bearing lubrication method, divided into grease lubrication and oil lubrication. In order to make the bearing play function very well, first of all, to choose suitable conditions, using the method of lubrication. If only consider lubrication, oil lubrication of lubrication advantage. But the grease around bearing structure can be simplified.
Components of hydraulic pump bearings pump is the most important bearing bearings.reduce negative pressure thrust ball bearing is the basic requirement of bearing load calculation of preventing water from entering the bearing to the oil. The locomotive maintenance is very important.
