Dyno mounted resilient couplings have a spider-type inner hub that mounts to the dynamometer shaft. The outer spider is positioned over the hub with a neoprene resilient block placed between each finger of the 2 spider assemblies. The coupling is capable of transmitting a maximum of 2,500 lb. ft. of torque when driving through the blocks. By removing blocks in pairs, torque rate can be reduced to 66, 50 or 33 percent, which becomes important when testing extremely small engines on large dynamometers.
Both types of resilient couplings are effective at reducing torque spikes and torsional vibrations.
