# Combined Radial and Axial Loads from Belt Drives and Couplings

## Combined Radial and Axial Loads from Belt Drives and Couplings

Electric motors often operate with belt drives, couplings, and gear meshes that create combined radial and axial loads on bearings. These loads vary depending on the operating mode.

## Sources of Loads

- Radial forces from belt tension
- Axial forces from helical gear meshes
- Moment loads from eccentric forces
- Dynamic loads during mode changes

## Solutions

Tapered roller bearings and angular contact ball bearings, which can withstand combined loads, are used. Paired sets of bearings are applied. It is recommended to select bearings with an optimal contact angle.
