Wear of spring-applied brakes

The table below shows the different causes of wear and their impact on the components of the spring-applied
brake. The influential factors must be quantified so that the service life of the rotor and brake can be calcu-
lated and so the prescribed maintenance intervals can be specified accurately. The most important factors
in this context are the applied friction energy, the initial speed of rotation of braking and the switching fre-
quency. If several of the causes of friction lining wear occur in an application at the same time, the influencing
factors should be added together when the amount of wear is calculated.

Component

Cause

Effect

Influencing factors

Friction lining

Braking during operation

Wear of the friction lining

Friction work

Emergency stops
Overlapping wear during start and stop of
drive
Active braking via the drive motor with sup-
port of brake (quick stop)
Starting wear in case of motor mounting
position with vertical shaft, even when the
brake is not applied

Number of start-stop
cycles

Armature plate and
counter friction
face

Rubbing and friction of the brake lining

Run-in of armature plate
and counter friction face

Friction work

Gear teeth of brake
rotor

Relative movements and shocks between
brake rotor and brake shaft

Wear of gear teeth (primar-
ily on the rotor side)

Number of start-stop
cycles

Armature plate
support

Load reversals and jerks in the backlash
between armature plate, adjustment tubes
and guide pins

Breaking of armature plate,
adjustment tubes and guide
pins

Number of start/stop
cycles, braking
torque

Springs

Axial load cycle and shear stress of springs
through radial backlash on reversal of arma-
ture plate

Reduced spring force or
fatigue failure

Number of switching
operations of brake
