Description

BeschreibungDescription

Bei Bremsen üblicher Bauart drücken die im Magnetkörper vorhandenen Druckfedern über die axial bewegliche Ankerscheibe den mit der Maschinenwelle formschlüssig verbundenen Bremsrotor gegen den Flansch. Durch das Einklemmen des Bremsrotors zwischen den beiden Reibflächen wird das Bremsmoment erzeugt.In conventional brake designs, the compression springs in the magnet body press the brake rotor, which is positively connected to the machine shaft, against the flange via the axially movable armature disk. The braking torque is generated by clamping the brake rotor between the two friction surfaces.

Da bei herkömmlichen Bremsen höheres Bremsmoment meist nur durch größere Bremsscheiben erreichbar ist, wurde aus Platzgründen eine Bremse gewünscht, die bei kleinst— möglichem Platz im Durchmesser sehr hohe Bremsleistung bringt.Since with conventional brakes a higher braking torque can usually only be achieved with larger brake discs, a brake was required for reasons of space that would provide very high braking performance in the smallest possible space in diameter.

Die Erfindung beruht nun auf dem Zusammenwirken vieler kleiner Bremsscheiben, die ein sehr hohes Bremsmoment ergeben.The invention is based on the interaction of many small brake discs, which result in a very high braking torque.

Claims (1)

SchutzansprücheProtection claims Ein Röntgenarm muß vom Bediener leicht in horizontaler Ebene bewegt werden können. Auf Knopfdruck muß die Bewegung festgestellt werden, um eine Röntgenaufnahme zu machen.An X-ray arm must be easily moved by the operator in a horizontal plane. The movement must be detected at the push of a button in order to take an X-ray image. Die Erfindung ist dahingehend gekennzeichnet, daß über hintereinanderiiegenden Lamellen ein sehr hohes Moment erbracht werden muß.The invention is characterized in that a very high torque must be achieved over successive slats.
