Abstract:
A rotor and shaft connector wherein the rotor extends radially relative to said shaft and includes a radially inner end and a base located at said radially inner end, comprising an annular drive arm for interconnecting said rotor and said shaft, a radially outer portion of said drive arm being attached to said base of said rotor and a radially inner portion of said drive arm being attached to said shaft, so that said rotor and said shaft are operationally maintained in radially spaced apart relationship, said drive arm including a portion that is so configured as to be semi-toroidal in configuration between said base and said shaft to define a radially outer rim of said drive arm that is attached to said base of said rotor, said drive arm additionally including a radially inner flange that is attached to a corresponding flange provided on said shaft, the arrangement being such that variation in stress distribution throughout said drive arm is minimized with consequent reduction in the magnitude of stress peaks therein.
