Abstract

A fan (not shown), for automotive cooling, having flexible blades which may reduce camber at increasing rotational speed, is mounted on a torsionally yielding coupling, as a vibration isolator (10, 110), comprising a first rigid support (14, 114) attached to the fan boss (50, 150), a second rigid support (12, 112) adapted for connection to a drive shaft (60, 160), and a resilient elastomeric member (16, 116) intermediate and arranged to transmit torque between the first and second supports while damping vibrations. The supports include spigot means for aligning the isolator coaxially with the fan and the drive shaft, and within the isolator further spigot surfaces in contact (19, 184, 186) maintain coaxial alignment. Alternative embodiments are shown. <IMAGE>
