Problems solved by technology

[0014] Since the damper plate is not preloaded when the armature disc is in the lowered state, the switching noise that occurs when the armature disc is attracted to the coil bracket cannot be effectively suppressed
[0015] The damper plate is presented as a stamped / bent part, which also has unnecessary errors in its dimensional accuracy

Embodiment Construction

[0052] figure 1 A perspective view is shown of an electromagnetically released spring pressure brake (FDB) in a fail-safe configuration, which consists of two brake circuits acting on the same rotor (7). This is a common design for redundant fail-safe brakes in passenger elevator areas. In the variant of the spring pressure brake (FDB) shown here, two armature disks ( 1 ) arranged in parallel are assigned to the coil carrier ( 3 ). The coil carrier (3) contains individual magnetic coils (5) and individual compression springs (4) for each armature disk (1). In this example, the spring pressure brake (FDB) is fastened to the motor end shield (M) using several screws (11). In addition, a flange plate (2) is provided between the motor end cover (M) and the rotor (7).

[0053] Figure 1.1 A complete section is shown, staggered through figure 1 The two brake circuits shown. A coil carrier (3) containing a compression spring (4) and a magnetic coil (5) is rigidly mounted on the...

Abstract

Electromagnetic switchable brake, preferably a spring pressure brake, comprising at least one coil carrier (3) and at least one armature disc (1), wherein the coil carrier and armature disc have a variable axial distance relative to one another, comprising at least one rotor (7) located on at least one hub of the shaft to be braked and comprising an end face and a mutual face of the coil carrier (3) arranged between the armature disc (1) and the coil carrier (3) Damping member between pairs of armature discs (1). It is considered novel and inventive that the body of the coil carrier (3) and / or armature disc (1) has an integral damper structure (D) consisting of at least one elastic tab (12) and foot (13) Composition, the elastic tab (12) is an integral part of the armature disc (1) or coil bracket (3) (Fig. 1.1).

Description

technical field [0001] The present invention relates to an armature disk or coil carrier having an integral damper structure for fail-safe brakes and operating current brakes. In this case, the fail-safe brake preferably comprises a friction brake, such as an electromagnetically released spring pressure brake or a permanent magnet brake. Background technique [0002] A fail-safe brake is generally understood to mean a braking system that produces a braking effect in the absence of an external energy supply, ie in a state of no current. Working current brakes work on the opposite principle. Therefore, a working current brake is generally understood as a braking system that requires an external energy supply in order to be able to exert its braking effect. This includes in particular so-called pole face brakes. [0003] Among other things, fail-safe current brakes are used in noise-sensitive applications. These include, for example, passenger elevators or stage and rope li...
