Abstract
A displaceable component includes a body having an axis and arranged for movement in at least one of an axial direction or a rotary direction about the axis. A position-defining element is fixed to the body and substantially comprising a magnetised elastomer. The position-defining element is arranged to be sensed by a sensor to determine at least one of an axial position, a rotary position or a rotary speed of the body.
Claims18
A displaceable component, comprising:
- a body having an axis and arranged for movement in at least one of an axial direction or a rotary direction about the axis;
- and
- a position-defining element fixed to the body and substantially comprising a magnetised elastomer, the position-defining element being arranged to be sensed by a sensor to determine at least one of an axial position, a rotary position or a rotary speed of the body.
A position determining system comprising:
- a displaceable component including a position-defining element substantially comprised of a magnetized elastomer providing a magnetic field useful to determine at least one of an axial position, a rotary position or a rotating speed of the displaceable component;
- and
- a sensing unit arranged proximate the displaceable component to sense the magnetic field of the position-defining element to determine at least one of the axial position, the rotary position, or the rotating speed of the displaceable component.
A method for manufacturing a displaceable component, wherein the displaceable component includes a position-defining element to determine a position of the displaceable component with the use of a sensor, wherein the position-defining element substantially comprises a magnetized elastomer, the method comprising:
- shaping the elastomer;
- and
- magnetizing the elastomer during the shaping.
A method for manufacturing a displaceable component, wherein the displaceable component includes a position-defining element to determine a position of the displaceable component with the use of a sensor, wherein the position-defining element substantially comprises a magnetized elastomer, the method comprising:
- vulcanizing the position-defining element to the displaceable component;
- and
- subsequently magnetizing the position-defining element.
