In order to meet the rapid development of the machine tool industry, as well as on the photoelectric industry small mechanical processing need, ultra-high speed air speed of static bearing now have more than 3 x10e6DN, equivalent to the surface of the shaft speed of mor e than 150 m/s. However, because of the bearing clearance in 5 to 20 range between um, under the speed that so, air film must have bear very high shear rate of ability. From this and come of viscous force for bearing the thermal performance and dynamic characteristics are deadly effect. Loadpoint new design with the combination of the successful ditch rolling bearing overcome the air of a series of problems.
This new design makes high-speed operation have improved, may increase the speed limit and hard and reduce operation of sex when temperature.angular bearing
Loadpoint new design effective overcome the main restricted factors, make aerostatic bearing achieve higher speed. The principle of aerodynamics and static mechanics principle combined, Loadpoint this area of the ditch rolling bearing-there are a combination of spiral groove roller neck bearing and a spiral groove thrust bearing, bearing rotation in the air when can squeeze center. In high speed, the role of the slot can significantly change bearing the distribution of internal pressure, improve the load capacity and stiffness. Spiral groove can also change the internal air membrane bearing speed and gradient, at the same time, reduce bearing viscous wear. Because aviation bearing viscous wear and area and space is proportional to the inverse ratio, minimum clearance at the same, with the combination of the ditch of rolling bearing friction than traditional bearing wants small. The higher the speed, the more obvious the advantages. With the combination of the ditch rolling bearing and the traditional aviation bearing performance difference can illustrate this point..
Along with the increase of the speed and shaft bearing clearance from 28 um minimum reduced to 16 um. In the low speed, the results and traditional bearing similar. However, when speed up to 12000 0 rev/min, take a ditch bearing the obvious advantage of, and could reach higher speed. The important thing is, with the combination of the ditch rolling thrust bearing and traditional thrust bearing, is still hardness. However, due to the function of the slot, and it consumes less energy.cross bearing
In addition, due to the influence of air power, hardness with increased with increasing speed. But the traditional thrust bearing no this function. With the combination of the first proof ditch the advantages of the rolling bearing is the internal hole heart the rotation of the body axis grinding of use. Proof of use, and traditional aviation bearing, compared with the combination of the ditch rolling bearings can make the rotating speed increased by 25% and current consumption is reduced by 10%.
People will also can design of high speed of spindle of machine miniature equipment of d iameter reduced to 50 um. Of course, high speed and the accuracy of the operation and the quantity of heat of slow reduce is not divided.angular contact bearing
