Cross-roller bearing for patient table for radiotherapy, has brake disk with friction surface cooperating with anti-friction surface on one of bearing rings or electrical coil without axial arrangement between other components

摘要

The bearing has cylindrical rolling members (7) arranged between an inner ring (1) and an outer ring (4). An electromagnetic brake device includes an electric coil (8) arranged in one of the bearing rings and integrated with the other of the bearing rings, and a brake disk (9) overlapping the electric coil. The brake disk includes a friction surface (11) cooperating with an anti-friction surface (12) on one of the bearing rings or the electrical coil without axial arrangement between other components.
