Abstract
An assembly of a rotating component and a rotationally stationary component includes a first bearing portion located at the rotating component and rotatable therewith, and a second bearing portion located at the rotationally stationary component. The second bearing portion is supported at the rotationally stationary component and rotatably with the rotating component when in contact with the first bearing portion. The first bearing portion and the second bearing portion define a single point contact therebetween.
Claims18
An assembly of a rotating component and a rotationally stationary component, comprising:
- a first bearing portion disposed at the rotating component and rotatable therewith;
- and
- a second bearing portion disposed at the rotationally stationary component, the second bearing portion supported at the rotationally stationary component and rotatably with the rotating component when in contact with the first bearing portion;
- wherein the first bearing portion and the second bearing portion define a single point contact therebetween;
- wherein when the first bearing portion contacts a contact surface of the second bearing portion, the second bearing portion rotates together with the rotating component.
A system for balancing a rotor assembly, comprising:
- an arbor to which a rotor assembly is installable, such that the arbor and rotor assembly are rotatable together about a central longitudinal axis;
- a first axial restraint disposed at a first axial end of the arbor, the first axial restraint rotationally stationary and configured to limit axial travel of the arbor toward the first axial restraint during rotation of the arbor;
- a first bearing assembly to operably connect the arbor to the first axial restraint, the first bearing assembly including:
- a first arbor bearing portion disposed at the arbor;
- and
- a first restraint bearing portion disposed at the first axial restraint;
- wherein the first arbor bearing portion and the first restraint bearing portion are configured to define a single point contact therebetween.
A method of operating a balancing system of a rotor assembly, comprising:
- installing a rotor assembly to an arbor;
- rotating the arbor and the rotor assembly together about a central longitudinal axis;
- limiting axial travel of the arbor along the central longitudinal axis via a first axial restraint disposed at a first axial end of the arbor, the first axial restraint rotationally stationary and configured to limit axial travel of the arbor toward the first axial restraint during rotation of the arbor;
- wherein a first bearing assembly is disposed between the arbor and the first axial restraint, the first bearing assembly including:
- a first arbor bearing portion disposed at the arbor;
- and
- a first restraint bearing portion disposed at the first axial restraint;
- wherein the first arbor bearing portion and the first restraint bearing portion are configured to define a single point contact therebetween.
