Abstract

A high temperature fan hub is secured to a hollow drive shaft by hollow driving pins projecting radially above the hub and extending transversely of the hub and shaft to communicate with the bore of the shaft. The hub has an end wall enclosing the bore at that end of the shaft to which it is secured and rotation of the shaft causes cooling fluid to be pumped from a remote point of the shaft such as the end of the shaft through the shaft bore and driving pins by centrifugal force to cool the hub and shaft at the joint thereof.
