(27) of one pair and at least one axis (28) of the other pair lie in a plane. The axes of one pair lie in a plane which is parallel to the touch pad surface when the touch pad is not pressed down. The four axes are preferably formed from two respective axial bearings (11,12;...
Touch down bearingsProblem to be solved: to prevent the touch down bearing from moving in a state in which the rotating shaft is not supported. The touchdown bearing 17 includes an inner ring 21, an outer ring 22, and a plurality of balls 23 interposed between the inner ring 21 and the...

The design of touch-down bearings (TDB) for vertical, magnetically levitated outer rotor flywheels with high rotational speeds and operation under vacuum conditions is a challenging task. Conventional TDB are not suited for big diameters with high rotational speeds resulting in surface speeds of above...
