Abstract
A method for producing a spray channel on a shaft tube, whereby a completed shaft tube can output fluid from within the shaft tube to outside of the shaft tube, the method may include introducing at least one through-opening with a diameter D1≥1.5 mm into the shaft tube and arranging at least one additional element in or on the at least one through-opening such that the spray channel is at least partly formed by the at least one additional element.
Claims13
A method for producing a spray channel on a shaft tube, the shaft tube is configured to output fluid from within the shaft tube to outside of the shaft tube via the spray channel, the method comprising:
- introducing at least one through-opening with a diameter greater than or equal to 1.5 mm into the shaft tube;
- and
- arranging at least one additional element in or on the at least one through-opening such that the spray channel is at least partly formed by the at least one additional element;
- wherein the spray channel is oriented at a right angle or at least partly obliquely to a shaft axis;
- and wherein the at least one additional element is a sleeve and is pressed into the through-opening to form the spray channel, an inner diameter of the sleeve is less than 1.5 mm.
A method for producing at least two spray channels on a shaft tube, the shaft tube is configured to output fluid from within the shaft tube to outside of the shaft tube via the spray channels, the method comprising:
- introducing at least two through-openings each with a diameter greater than or equal to 1.5 mm into the shaft tube, the at least two through-openings are oriented orthogonally to a shaft axis;
- and
- arranging an additional element in or on the at least two through-openings such that the spray channels are at least partly formed by the additional element;
- wherein the additional element is formed as an outer ring, and wherein each of the at least two spray channels includes a diameter less than 1.5 mm.
A method for producing at least two spray channels on a shaft tube, the shaft tube is configured to output fluid from within the shaft tube to outside of the shaft tube via the spray channels, the method comprising:
- introducing at least two through-openings each with a diameter greater than or equal to 1.5 mm into the shaft tube, the at least two through-openings are oriented orthogonally to a shaft axis;
- and
- arranging an additional element proximate the at least two through-openings such that the spray channels are at least partly formed by the additional element;
- wherein the additional element is formed as an inner ring, and wherein each of the at least two spray channels includes a diameter less than 1.5 mm is provided, and each spray channel runs obliquely or orthogonally to an inner ring axis.
A method for producing a spray channel on a shaft tube, the shaft tube is configured to output fluid from within the shaft tube to outside of the shaft tube via the spray channel, the method comprising:
- introducing at least one through-opening with a diameter greater than or equal to 1.5 mm into the shaft tube, the at least one through-opening is oriented orthogonally to a shaft axis;
- and
- arranging an additional element in or on the at least one through-opening such that the spray channel is at least partly formed by the additional element;
- wherein the additional element is formed as a ring with a front face extending obliquely to the shaft axis, the front face forms a part of the spray channel.
A method for producing at least two spray channels on a shaft tube, the shaft tube is configured to output fluid from within the shaft tube to outside of the shaft tube via the spray channels, the method comprising:
- introducing at least two through-openings each with a diameter greater than or equal to 1.5 mm into the shaft tube, the at least two through-openings are oriented orthogonally to a shaft axis;
- and
- arranging an additional element in or on the at least two through-openings such that the spray channels are at least partly formed by the additional element;
- wherein the additional element is a sphere ring including at least two interconnected spheres;
- and wherein into each sphere a spray channel of the at least two spray channels running obliquely or orthogonally to a sphere ring axis with a diameter less than 1.5 mm is disposed;
- and wherein the sphere ring is mounted on the shaft tube such that each of the at least two interconnected spheres engages an associated through-opening of the at least two through-openings and fluidly connects the respective spray channel with the associated through-opening.
