Small reversal spreading support bearings are usually composed of worm, reversing support, housing, motor and other components. Since the core components are supported by reversal, they may receive axial force, radial force, and tilting moment at the same time. There are many methods, but the basis of the layout is similar. Splitting from the left and the left is (upper door): 1. Outer ring (with or without teeth) 2. Sealing belt 3. Rotating body (roller or roller) 4. Refueling nozzle.
Splitting from left to left is (high part): 1. choked 2. choked pin 3. inner ring (with or without teeth) 4. isolation block or cage 5. device hole (silk hole or smooth hole).
According to the different layout types, the small reversal spread slewing bearing may be divided into four-point ball slewing bearing, crossed cylindrical (tapered) roller slewing bearing, single-row four-point ball slewing bearing, single-row reducing ball slewing bearing, ball- Roller combinations and three-row cylindrical roller combined slewing bearings have different layout types; the above-mentioned bearings are divided into toothless, external or internal gears according to whether they are toothed or not. layout.
The small reversing and spreading support bearings are designed according to different layout characteristics to increase the needs of the work host before different loads. Here, the four-point fighting ball slewing bearing has a higher dynamic load capacity, the crossed cylindrical roller slewing bearing has a higher static load capacity, and the three-row cylindrical roller combined slewing bearing leads to the height deviation of the bearing due to the increase in the load capacity. , All kinds of loads are received by the different rolling and rolling roller group, so it is improved before the equal force. Its rolling diameter is greatly reduced, and it has the characteristics of making the host more loose. It is a high-loading capacity slewing bearing.
