Abstract
Nut (1) for moving a strip for transporting powder in a selective additive manufacturing apparatus, having a tapped hole (2) extending along a first axis (A), characterized in that it comprises a slot (3a, 3b) which passes through the thickness of the nut from an external surface of the nut (1) to the internal surface (5) of the tapped hole (2) and which extends along a plane passing through the first axis (A) over at least one thread pitch (6) of the tapped hole (2).
Claims12
A nut for moving a strip for transporting powder in a selective additive manufacturing apparatus, the nut comprising:
- a tapped hole extending along a first axis;
- and
- a slot which passes through a thickness of the nut from an external surface of the nut to an internal surface of the tapped hole and which extends along a plane passing through the first axis over at least one thread pitch of the tapped hole,
- wherein the external surface of the nut is a cylinder that comprises two grooves extending along the first axis, each groove being formed by a first rectangular surface parallel to a second axis and by a second rectangular surface parallel to a third axis, the two grooves being positioned in a zone diametrically opposite the slot.
A system for setting in motion a strip for a selective additive manufacturing apparatus comprising:
- a nut for moving a strip for transporting powder in a selective additive manufacturing apparatus, the nut comprising:
- a tapped hole extending along a first axis;
- and
- a slot which passes through a thickness of the nut from an external surface of the nut to an internal surface of the tapped hole and which extends along a plane passing through the first axis over at least one thread pitch of the tapped hole;
- a strip to which the nut is fixed such that the nut is prevented from rotating with respect to the strip;
- and
- a screw comprising a thread engaged in the tapped hole of the nut,
- wherein the slot in the nut is situated in a zone diametrically opposite the strip with respect to the first axis.
