The invention relates to a mounting of one or more electromagnetically bleeding spring-loaded brakes (a, b) on a machine wall or the like. The invention is characterized in that the brakes are, while distributed over the periphery on the face, act upon an axially moving brake rotor ( 5 ) with continuous friction linings ( 6 ) on both sides (i.e. left and right), whereby braking (left) surface of the friction lining ( 6 ) and on the opposite side with the armature discs of the brakes on the second (right) friction lining ( 6 ).
1. A segment brake comprising an axially moveable brake rotor for connection to a rotary output shaft of a machine, said rotor having friction liners on opposite axially facing sides of said rotor and a plurality of electromagnetically disengaging spring pressure brakes for attachment to a wall of a machine having a rotary shaft to be braked, said brakes being radially spaced from the axis of rotation of said rotor and each having a coil carrier, at least one electrically energizable coil in said carrier and an axially moveable spring biased armature disc retractable toward said carrier against spring pressure by electric energization of said coil, said armature disc engageable during braking with one friction liner on said rotor and an oppositely facing friction liner on said rotor being engageable during braking with said wall, said armatures and coil carriers being rectangular in shape, each coil carrier containing an oval shaped coil configured to optimize the use of available space.
2. The segment brake of claim 1 , further comprising threaded fasteners for attaching said brakes to said wall.
3. The segment brake of claim 2 , further comprising a splined hub affixed to said rotor.
4. The segment brake of claim 1 , further comprising disengagement monitoring means for indicating engagement or disengagement of said brakes.
5. A segment brake comprising an axially moveable brake rotor for connection to a rotary output shaft of a machine, said rotor having friction liners on opposite axially facing sides of said rotor and a plurality of electromagnetically disengaging spring pressure brakes for attachment to a wall of a machine having a rotary shaft to be braked, said brakes being radially spaced from the axis of rotation of said rotor and each having a coil carrier, at least one electrically energizable coil in said carrier and an axially moveable spring biased armature disc retractable toward said carrier against spring pressure by electric energization of said coil, said armature disc engageable during braking with one friction liner on said rotor and an oppositely facing friction liner on said rotor being engageable during braking with said wall, said armatures and coil carriers being rectangular in shape, and said coil carriers each containing two annular magnetic coils configured to optimize the available space.
6. The segment brake of claim 5 , further comprising threaded fasteners for attaching said brakes to said wall.
7. The segment brake of claim 6 , further comprising a splined hub affixed to said rotor.
8. The segment brake of claim 5 , further comprising disengagement monitoring means for indicating engagement or disengagement of said brakes.
