Step 8: Checking the external additional forces – F_R

The permitted external additional forces are determined by the following factors:

• Service factor
• Required bearing service life
• Direction of the axial load (from or to the gear unit)
• Application angle of the overhung load (circumferential or at certain application angle)
• Application point of the overhung load in relation to the shaft collar
• Ratio of axial to overhung load

• Dependencies
• Definition of the force application
• Determining the overhung load
• Maximum permitted gear unit overhung loads FRmax per
