Abstract
An elevator brake (20) rotor for use in an elevator machine (10) includes a non-metallic elevator brake hub (36) and a metal flange (34), both of which have an opening with a splined portion for guiding axial movement of the rotor along a rotable shaft (14). This arrangement reduces metal-to-metal contact between the rotor and shaft and reduces noise.
