The invention relates to an axial spring element () having two peripheral ring elements () that are spaced from one another in the axial direction and are connected to one another in a spring-elastic manner, wherein at least one of the ring elements () comprises one or more retaining elements () in order to brace the spring element with a rotor () and thereby hold the spring element on the rotor ().

Electric machine having an axial spring element

A driving device () for driving a unit () is specified, with a drive shaft () on which a plurality of rolling bearings (to) serving to drive respective functional elements of the unit () are arranged next to one another. The rolling bearings (to) are designed as unencapsulated needle bearings (to) and are arranged directly next to one another on the drive shaft () in such a manner that the inner ring () of a needle bearing () is in touching contact by means of its end surface (), which is located on an axial side, with the facing, axial end surface () of the outer sleeve () of the needle bearing () following next axially.
