Abrasion buildup on the friction linings

Brakes are subject to different kinds of wear depending on the application. As such, planning regular inspections and maintenance is an important aspect of drive project planning.

The expected service life of the friction lining is determined as a main variable using the characteristic value W_Insp.

In addition, there are other influencing factors that can lead to wear effects on brake linings and mechanical guiding elements. This also applies for applications in which the brakes are only used in emergency stop situations (holding brakes).

These special wear factors include:

• No-load wear
• No-load wear is always caused by the residual friction always present in the brake.
• Mounting positions that lead to a vertical alignment of the longitudinal motor axis.
• Due to the weight of the brake's lining carrier, larger brakes (BE20 and larger) undergo greater wear, especially on the bottom of the lining.
• Double disk brakes
• Double disk brakes have an increased wear, especially in pivoted mounting position, due to the support of the brake plate.
• Performing activation processes
• Friction work is used in every process. The number of activation processes and the friction work used per process must be taken into account when determining the lining service life.

All listed factors can additionally reduce the calculated service life. The /DUE option and the integrated BG1Z brake control offer wear monitoring.
