Air flow test machine for rotors

Abstract

The invention relates to an air flow test apparatus for determining the amount of air moving through vents in a turning ventilated rotor. The air flow test apparatus includes an elongated cylindrical shaft journalled for rotation in spaced apart bearing blocks mounted in a frame. A conventional belt drive couples the shaft to a variable speed motor for rotation. An adapter is mounted to the shaft and a work piece is mounted to the adapter end for rotation with the shaft. The work piece includes a hub secured to the adapter for receiving a plurality of different sized rotors, and a ventilated rotor mounted to the hub. The work piece may also include other vehicle components such as the caliper, a wheel, even an entire corner portion of a vehicle for simulation purposes. A pressure gauge is disposed adjacent the rotor, near the vents, to measure the air pressure near the turning rotor. The cooling effectiveness of the ventilated rotor can be determined by the amount of air moved through the vents which is proportional to the change in pressure of the moving air.
