How to lubricate high-precision FAG bearings0bellaer2020-07-27 19:06:35
The difficulty of lubricating high-precision FAG bearings is that the lubricant is easy to scatter, and it is not easy to adhere to the rolling surface, or it is blocked by the high-speed airflow around the FAG bearing and cannot enter the FAG bearing. The lubricant speed entering the FAG bearing is too high, sometimes FAG bearings will be damaged, such as pitting in the cage, chipping and increased friction and wear. 6313-2Z FAG bearing online The working temperature of high-speed FAG bearings is mostly around 200 ° C, and they tend to be higher. If they are not cooled by strong force, the temperature will continue to rise, which will be detrimental to the strength and hardness of FAG bearings. Once FAG bearings lose the ability to maintain accurate shapes It will intensify the high-speed friction and cause the temperature to rise rapidly, which further leads to a decrease in the strength and hardness of the material and makes the FAG bearing fail quickly. Because high-speed FAG bearings are very sensitive to wear and are prone to wear debris, if they are not removed from FAG bearings in time, they will also cause a vicious cycle and make FAG bearings fail quickly. Therefore, the task of high-speed FAG bearing lubrication must effectively deliver the lubricant to the moving surface in the FAG bearing, and remove the heat from the FAG bearing, and at the same time remove the abrasive particles or dirt from the FAG bearing. The following are the commonly used lubrication methods and effective lubricants in high-speed FAG bearings. Jet lubrication The jet lubrication method is to spray lubricating oil from the nozzle hole close to the FAG bearing at a speed of 10-20m / s into the FAG bearing, usually sprayed into the gap formed by the cage and the inner ring or outer ring to lubricate And the method of cooling FAG bearings. For small ball FAG bearings with an internal diameter of 30-35mm, the dmn value limit of jet lubrication can reach 3 million, and 2.5 million for larger FAG bearings. Double-hole or multi-hole nozzles can not only increase the oil supply, but also improve the use efficiency of lubricating oil. Multiple nozzles or nozzles on both end surfaces can improve the lubrication and cooling effect, but when the dmn value is close to 2 million Due to the influence of centrifugal inertia and wind resistance, the oil sent to the FAG bearing is only 70% or less of the nozzle flow. Under ring lubrication The under-ring lubrication method uses centrifugal inertia to directly spray oil toward the surface of the raceway through many small radial holes in the inner ring. A part of the oil flows axially under the inner ring to cool the inner ring. The oil entering the raceway is divided into two left and right channels to flow out, and the abrasive debris falling from the cage and other parts is washed away by the way. The amount of oil used in this lubrication method is much less than that of oil injection lubrication. The power loss caused by the dynamic stirring of the oil is also less. The heat generation of the FAG bearing is also greatly improved. Even the inner ring temperature may be lower than the outer ring. Reduce the failure rate of FAG bearings. This lubrication method can also be used to cool the outer ring. When both the inner and outer rings are lubricated, the allowable dmn value of FAG bearings can be further increased. Now this under-ring lubrication method is widely used in various ultra-high-speed operation occasions. The achievable large dmn value is 3 million for large ball FAG bearings with an inner diameter of 120 to 200 mm; 2.4 million for tapered roller FAG bearings with an inner diameter of 120 mm, and 3 million for short cylindrical roller FAG bearings with combined inner rings Double lubrication In this method, the inner ring hole of the rolling FAG bearing and the journal form a static pressure oil film sliding FAG bearing, which greatly reduces the rotating speed of the rolling FAG bearing, thereby achieving the purpose of reducing the effect of centrifugal force. Such a double-lubricated FAG bearing can Significantly reduce the rotation speed of the inner ring of the rolling FAG bearing, thus allowing the spindle to have a higher rotation speed, which is equivalent to the dmn value of the FAG bearing can be further increased. Oil-air lubrication method The big advantage of the oil-air lubrication method is that it is possible to achieve a high speed of dmn value of 800,000 to 1.5 million by reducing the friction of the FAG bearing without changing the structure of the FAG bearing. For the FAG bearing with more internal sliding, this method The advantages are even more significant. Lubricant for high-speed FAG bearings The lubricant for high-speed FAG bearings should be considered as the lubricant for high-temperature FAG bearings, that is, synthetic oil with good performance at high temperatures, or grease based on this synthetic oil. The diester-based MIL-L-7808 oil and MIL-L-23699 oil have been widely used in FAG bearings of jet engines.

NBA2king - Even the NBA 2K franchise is known for the precision0Kingang2021-05-04 20:57:46
Nobody knows that the 2020 NBA 2K MT  season has been especially intermittent because of the pandemic, as it's happened in a number of other sports less influenced by it. Even the draft, another great spectacle of sport in the united states, has only been held . But fans that haven't had all the NBA that we'd have liked have been the consolation of going down to the courtroom together with our favorite players at pavilions full of noisy digital audiences thanks to simulators such as NBA2K21. And thanks to its successive evolutions of the game there is everything: realistic images, strategy, team direction and the possibility of making a livelihood in the NBA using our own"rookie". And it's that since 1999 Visual Concepts has been attaining the ideal basketball game in terms of the precision of the simulation, the movements of the players (some unmistakable and deadly ), the visual details of the same (like tattoos) and it is done a great job of upd ating all of this with periodic downloads of modifications made by the game team when there are changes from the teams together with additions or deletions of new players. Can this create Nba 2k21 myteam mt for sale a excellent game? Does this represent a substantial evolution in comparison to previous editions? We'll see later.

Correct Use Of FAG Bearings02020-10-26 00:26:27
Click here for more details about SKF 6309-2Z * bearing.  FAG bearing assembly method Because FAG bearings are precision products, such as improperly assembled channels, it is easy to cause damage to FAG bearings. When assembling FAG bearings, there should be a special mold, which can not hit people. The pressure when entering the shaft can only be a small circle. When the circle, only the force is cycled. The assembly requires pneumatic or hydraulic pressure to be installed on the upper and lower molds in a horizontal state. If the INA bearing channel is inclined, it will cause damage to the power and cause the bearing to cause the FAG bearing.
FAG Electrically Insulated Bearings0bellaer2020-07-06 17:46:09
6332 FAG bearing online  Overcurrent often occurs on wheelset bearings and traction motors (rail vehicles), DC and AC motors (power transmission systems), and generators (wind power). Overcurrent may cause damage to the raceway and rolling elements and the aging of the lubricant, causing premature failure of the motor or generator, resulting in increased maintenance costs and losses caused by shutdowns and shutdowns. Rolling bearings used in some related equipment such as motors and generators are likely to be affected by the passage of current during use. This will not only damage the rolling elements and raceways in the bearings, but also affect the grease. performance. In general, it is very difficult to completely eliminate the potential difference inside the bearing, but it can prevent or greatly reduce the current passing through the bearing to prevent electrical corrosion of the bearing. The induced voltage generated along the shaft will generate a current loop through bearing A, bearing housing and bearing B at the same time.  One reason for this type of shaft voltage is due to the uneven distribution of magnetic flux inside the motor, especially in motors with few pole pairs.  In this case, as long as the bearing at one end is insulated, the current loop can be completely cut off, and the bearing at the non-drive end is usually insulated. If a voltage occurs between the shaft and the bearing housing, current will flow through each bearing in the same direction. In this case, the bearings on both ends of the motor should be insulated. The decisive factor in choosing insulation is the time characteristic of the current. If it is a DC voltage or a low-frequency AC voltage, the insulation effect depends on the pure resistance value of the insulation layer; if it is a high-frequency AC voltage (common in equipment that uses an inverter), it depends on the capacitance reactance value of the insulation layer. Is it too professional to look at these, but as long as we have products to deal with them, that is electrically insulated bearings. Both the inner ring and the outer ring with ceramic coating bearings are called insulated bearings.  The ceramic coating can prevent electric current from passing, and has the insulating ability. The rolling elements of the hybrid bearing are made of ceramics, and the rolling elements prevent the current from passing through, so they also have insulation capabilities. FAG insulated bearings are standard bearings with ceramic coating Insutect on the outer ring or inner ring, and have the following characteristics:
