Description

Structural characteristics, performance, scope of application
The double volley ball slewing bearing has three races, and the steel balls and spacers can be directly discharged into the upper and lower raceways. According to the stress conditions, two rows of steel balls with different diameters are arranged. This open assembly is very convenient. The bearing angles of the upper and lower arc raceways are 90 °, which 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 volley ball slewing bearing has relatively large axial and radial dimensions, and its structure is tight. Particularly suitable for tower cranes, truck cranes and other loading and unloading machinery that require medium or larger 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 replaced with screw holes; the tooth width b can be changed to H-h.
3. The circumferential force of the Gear in the table is the maximum circumferential force, and the rated circumferential force is 1/2.
4. Internal tooth trimming coefficient is 0.2.
