Abstract

An improved mechanism for securing a rotor is provided. The rotor may have an end portion with a first surface. The first surface may be threaded. The first surface of the end portion of the rotor may be different than the portion of the rotor not consisting of the end portion. A drive object may have a second surface formed on a face of the drive object to receive the first surface of the rotor. The second surface may be threaded to complement the first surface of the rotor. The drive object and the rotor may be removably affixed by threading the two surfaces together. In some embodiments, the threading on the two surfaces may follow the direction of rotation of the rotor. In some embodiments, the second surface may be made of a material that is softer than the first surface.
