4.2.9 Step 9: Checking the thermal rating:
The gear unit’s thermal rating must be at least as large as the operating power on the
input shaft [HSS]
PT ≥ PK1 4.2.10 Step 10: Checking the external additional forces:
Dependencies The permitted forces on the shaft depend on the following factors:
• Service factor
• Required bearing service life
• Direction of the axial load (from or towards gear unit)
• Application angle of the overhung load (rotating or at a specific position)
• Application angle of the overhung load in relation to the shaft shoulder
• Relation axial load/overhung load and vice versa
