Maintenance and repair
8.1
Wear of spring-applied brakes
WARNING
Braking torque reduction
The system must
not
be allowed to continue operations after the maximum air gap s
Lmax
has been exceeded. Exceeding the maximum air gap can cause a major reduction in the
braking torque!
The table below shows the different causes of wear and their impact on the components of the spring-ap-
plied brake. The influential factors must be quantified so that the service life of the rotor and brake can be
calculated and so that the prescribed maintenance intervals can be specified accurately. The most impor-
tant factors in this context are the applied friction work, the initial speed of rotation of braking and the oper-
ating frequency. If several of the causes of friction lining wear occur in an application at the same time, the
effects should be added together when the amount of wear is calculated.
