Air gap “a“
Release inspection
When the magnetic coil in the coil
carrier (Item 2) is energised, the
armature disk (Item 3) is pulled
towards the coil carrier (Item 2).
The microswitch (Item 1) emits a
signal and the brake is released.
Wear inspection
Due to wear on the rotor (Item 5),
the nominal air gap “a” between
the coil carrier (Item 2) and the
armature disk (Item 3) increases.
If the limit air gap (see Table in
the Installation and Operational
Instructions) is reached, the
microswitch contact (Item 1)
switches over and emits a signal.
The rotor (Item 5) must
be replaced.
In de-energised
condition, the brake
with lockable hand
release can be
released manually.
By moving the hand
release rod (Item 1),
the armature disk
(Item 3) is pushed
against the thrust
springs (Item 4) onto
the coil carrier (Item
2) and the braking
torque is removed.

Continuous shaft with IP65
The enclosed design (IP65) is
equipped with a screw plug (sizes 8
to 500) or with a sealing cover (size
1000) (see Type 891._14.1, page 5)
as part of the standard delivery.
A radial shaft sealing ring (Item 1)
is installed in the coil carrier (Item 2)
on continuous shafts.
Damping rotor/gear hub
If vibrations in the drive line cannot
be avoided, an O-ring (Item 1)
is used to damp backlash between
the gear hub (Item 6) and the rotor
(Item 5).
Anti-condensation heating
The anti-condensation heating
(Item 1) is used to prevent
condensation formation
inside the brake.
This product is particularly
useful at temperatures of under
zero degrees Celsius or in high
humidity.
Special flange plate
We offer a range of flange plates
for customer-specific solutions,
such as for example the special
flange plate shown in Fig. 7
(Item 1) with customer-tailored
centring (Item 8) and sealing
(Item 7).
Lockable hand release
In addition to the standard brakes, mayr
®
power transmission
provides a multitude of further designs, which cannot be described
in detail in this catalogue.
Some of the most frequently requested options are:
Microswitch for switching condition indication (release
inspection)
Microswitch for wear indication (wear inspection)
Special coil voltages
Lockable hand release
IP65 design for continuous shafts
Noise damping (O-ring damping between the gear hub
and the rotor)
Anti-condensation heating
Customer-specific flange plate
Special lubricating material
ATEX design
