Abstract
A fan rotor ( ) for an electromagnetic fan clutch is mounted on a drive shaft ( ) with the help of a three-ring bearing ( ) so that three different speeds of rotation of the fan rotor ( ) can be obtained. To reduce wear, especially in the presence of impact loads and oscillatory movements of the three-ring bearing ( ), this three-ring bearing ( ) is configured so that different materials are paired with each other in regions of rolling contact.
