Figure 2: Spindle model
(English and English notes: Loads and Moments acting on the rotor – Force and moment acting on the rotor; Double row Tapered roller bearing – Double row tapered roller bearing; Solution1: TDI + CRB – Option 1: Double row tapered roller bearing + Cylindrical roller bearing; Cylindrical roller bearing – Cylindrical roller bearing; Spherical roller bearing – Spherical roller bearing; solution2: SRB+SRB – Option 2: Spherical roller bearing + Spherical roller bearing)
The bearings are lubricated with ISO VG320 viscosity grease and the operating temperature is assumed to be 40 degrees Celsius.
