Test System for Chain Wheels


With a total of 9 diff.-probes the chain wheels, made of sintered metal, are tested.

The parts are put separately on a double track tape and transported to the stations.

Each station tests one side while a turning device between the stations turns the parts over.

The evaluation of the crack signals is provided by a downstream digital signal processing inside the PC.

At the same time it is used as operator device and fort he display of the system’s status.

The signal is taken by the crack detection unit WRP and converted for further procession in the control system (PC).

As soon as a crack on the surface is discovered, the information passed on to the SPS of the system and the chain wheel will be sorted out.

The sorting of the parts happens at the end of the transport belt with a pneumatically activated switch.
