ABSTRACT:
A tuned quick connect and disconnect coupling arrangement includes a tubular adapter removably secured to the output shaft of an engine and has an external spline formed on its periphery. A tuned resilient coupling assembly is secured to the dynamometer input shaft and has an internal spline adapted for meshing engagement with the external spline of the adapter for drivingly coupling the shaft to one another for checking the power output of the engine and is disengageable therefrom for uncoupling the shafts from each other. The coupling assembly includes an annular ring containing the internal spline, an elongate torque tube having a pair of radially outwardly extending flanges secured thereto at its opposite ends with one of the flanges resiliently connected to the annular ring, and a hub having a radially outwardly extending flange formed thereon resiliently connected to the other flange of the torque tube. The hub is secured to the dynamometer input shaft for imparting rotation thereto through a diametral tapered bore formed in the hub, a device operatively associated with the dynamometer input shaft and which provides a complementary external tapered surface, and a device operatively connected to the hub to axially draw the external tapered surface into wedging gripping relation with the tapered bore to drivingly interlock the hub to the input shaft.
