Design of a Dynamic Gear Test Rig
A test rig for plastic spur gears has been designed and built, based on the principle of an eddy current dynamometer. This offers considerable advantages over existing gear test rigs in that the torque level is infinitely variable and it can be adjusted if necessary during testing. A special noncontacting tooth breakage detector was also developed to stop the tests immediately if failure had occurred.
An extension to the basic test procedure is also described whereby real life loading situations can be easily simulated with a minicomputer coupled to the dynamometer.
