Double Row Different Ball Slewing Bearing(02 series)——Internal Gear

Structural characteristics, performance, and scope of application

The double volleyball slewing bearing has three races. The steel ball and the spacer block can be directly discharged into the upper and lower raceways. According to the force condition, two rows of steel balls with different diameters are arranged. This open assembly is very convenient, the upper and lower circular races have a bearing angle of 90° and can withstand large axial forces and tipping moments. When the radial force is greater than 0.1 times the axial force, the raceway must be specially designed. The double volleyball type slewing bearing has relatively large axial and radial dimensions and is structurally fastened. It is especially suitable for loading and unloading machines such as tower cranes and truck cranes that require medium and large diameters.



Note:
1. n1 is the number of lubricating oil holes, evenly distributed: oil cup M10×1 JB/T7940.1-JBT7940.2
2. The mounting holes n-dn1 and n-dn2 can be changed to screw holes; the tooth width b can be changed to H-h.
3. The circumferential force of the gear in the watch is the maximum circumferential force, and the rated circumferential force is 1/2.
4. The internal tooth repairing coefficient is 0.2.
