LEONESSA slewing ring replacement

In order to choose a slewing ring the following information are required:

• application description

• working loads on the slewing ring

• operating cycle

• slewing torque

• overall envelope

The first cut design of a slewing ring can be done by comparing the applied loads with the load capacity of the raceways. The load capacity of a slewing ring is reported in a load chart and it is calculated by taking into consideration:

• slewing ring geometry

• rings material

• heat treatment parameters of the raceways

• dimensions, material, heat treatment and number of rolling elements

• contact parameters

The load chart is represented in a Cartesian diagram reporting the compression axial force [kN] on the x-axis and the tilting moment [kNm] applied to the slewing ring on the y-axis. The point representing the maximum load, multiplied by the coefficients of application, has to fall below the application limit curve
