Housing and hub for an apparatus for securing a workpiece to a rotatable machine member

A housing and hub for an adapter system for securing a rotor to a lathe, comprising:

• a hub formed with an exterior face, the hub being slidably engageable with a rotatable driven shaft of the lathe,
• wherein the exterior face further comprises a first channel girding the hub,
• and further wherein the first channel includes a layer of elastomeric material;
• a centering device positionable on the shaft;
• a spring having a distal end and a proximal end, the distal end insertable in the hub, the proximal end connectable to the centering device;
• and
• a housing formed with an exterior wall, the housing being freely movable axially on the shaft for locating the rotor substantially perpendicularly to the shaft,
• wherein the exterior wall further comprises a second channel girding the housing,
• and further wherein the second channel includes a layer of elastomeric material.

A method for securing a rotor to a lathe, comprising the steps of:

• providing a hub formed with a first banded channel, said hub being slidably engageable with a rotatable shaft of the lathe;
• installing a centering device axially positionable on the shaft;
• including a spring demountably insertable in the hub and connectable to the centering device;
• furnishing the system with a housing formed with a second banded channel, said hub being freely locatable on the shaft for securing the rotor in the system in a substantially vertical position;
• and
• equipping the lathe with a locking nut.
