Assembly comprising a radially intermediate joint and corresponding method of joining two components
Patent number: 9415633Abstract: An assembly includes a first component joined to a second component by an intermediate joint. The first component has a first joining surface arranged coaxially and spaced in a juxtaposition around a second joining surface of the second component such that a groove is defined between the first and second joining surfaces. One of the first and second joining surfaces includes a concave portion and the other of the first and second joining surfaces has a convex portion radially opposite the concave portion, and the groove is formed by the convex and concave portions. The intermediate joint is formed by an insert ring pressed into the groove and deformed such that material of the insert ring fills the concave portion and surrounds the convex portion, and this locks the first and second components relative to each other in both axial directions.Type: GrantFiled: May 28, 2010Date of Patent: August 16, 2016Assignee: AKTIEBOLAGET SKFInventors: John van de Sanden, Cornelius Petrus Antonius Vissers, Victor Haans, Maarten Noordman -
Publication number: 20150343553Abstract: A machine arrangement, comprising at least one carrier, wherein a glass fiber is connected with the machine arrangement. To allow a proper measurement of stresses even at curved surfaces of the machine arrangement, as it is typical in the case of a carrier being attached to bearing rings, the connection between the glass fiber and the machine arrangement is established by a metallic material which metal material is connected by material bonding with the machine arrangement as well as with the glass fiber.Type: ApplicationFiled: June 14, 2013Publication date: December 3, 2015Inventors: Hendrik Anne MOL, John VAN DE SANDEN, Hongyu YANG

Publication number: 20140377586Abstract: The present invention resides in an assembly comprising a first steel component that is joined to a second steel component by a weld joint formed in a hybrid welding process, whereby at least one of the first and second steel components comprises a through-hardened bearing steel. In the hybrid welding process, base material of the first and second steel components is melted and a moulten filler material comprising at least 90% Nickel is added. The weld joint is formed after solidification of the moulten base material and of the moulten filler material. According to the invention, the weld joint comprises a central solidified portion and a peripheral solidified portion, whereby the central solidified portion comprises at least 80% filler material and the peripheral solidified portion comprises no more than 20% filler material.Type: ApplicationFiled: January 25, 2013Publication date: December 25, 2014Applicant: Aktiebolaget SKFInventor: John Van De Sanden

Patent number: 8906596Abstract: The present invention resides in a method of providing a mark on a surface of a metal component, where the mark comprises a symbol (301) representing a first entity of information and the method comprises a step of laser marking, in which a controllable laser beam is used to form the symbol (301) from two or more separate line segments (33 1-334), each line segment (33 1.334) having at least one point of overlap with another line segment. According to the invention, the method further comprises a step of embedding a second entity of information within the mark by modifying a sequence in which the two or more separate line segments (33 1-334) are formed.Type: GrantFiled: February 19, 2010Date of Patent: December 9, 2014Assignee: Aktiebolaget SKFInventors: John Van De Sanden, Hendrik Johannes Krock, Hendrik Anne Mol

Patent number: 8833173Abstract: The present invention defines a strain sensor for measuring strains induced on a component surface (34). The strain sensor comprises a strain gauge (31) and a support member (32), whereby the support member is attached to the component surface only at first and second attachment places. The support member comprises a beam portion (39) that is adapted to bend in response to a relative displacement of the first and second attachment places, and the strain gauge is integrated on a surface (33) of this beam portion. To ensure a strong and stable bending response of the beam portion, the attached support member comprises at least one flexure hinge (45).Type: GrantFiled: July 17, 2009Date of Patent: September 16, 2014Assignee: Aktiebolaget SKFInventors: Hendrik Anne Mol, John Van De Sanden, Laurens Verhulst

Patent number: 8829390Abstract: The present invention relates to a method of manufacturing a bearing component, in which a visible identification mark is created on a surface of the component using a laser beam. The laser marking creates an oxidized layer on the component surface and, in an underlying region, alters the microstructure of the bearing steel from which the component is made. According to the invention, the mark is then rendered visually undetectable with the naked eye, by removing at least the oxidized surface layer of the mark. This exposes the altered microstructure, which is revealable by applying an etchant to the visually undetectable mark.Type: GrantFiled: December 22, 2009Date of Patent: September 9, 2014Assignee: Aktiebolaget SKFInventors: John Van De Sanden, Hendrik Johannes Krock, Hendrik Anne Mol

Patent number: 8796584Abstract: The present invention relates to a method of manufacturing a bearing component, in which a visually undetectable identification mark is created on a surface of the component by means of laser marking performed in a protective gas environment. The protective gas environment prevents the formation of a visible oxide layer, while the temperatures induced at the component surface and below the component surface, due to the laser marking, are sufficient to alter the microstructure of the bearing steel from which the component is made. The altered microstructure is revealable by applying an etchant to the visually undetectable mark, thereby allowing authentication of the bearing component.Type: GrantFiled: December 22, 2009Date of Patent: August 5, 2014Assignee: Aktiebolaget SKFInventors: John Van de Sanden, Hendrik Johannes Krock, Hendrik Anne Mol

Publication number: 20130147257Abstract: The present invention resides in a wheel bearing assembly (100) comprising a flanged hub (110) and at least one second component (130) that is joined to the flanged hub by means of a radially intermediate joint (160). Specifically, the flanged hub has a first joining surface and the second component has a second joining surface, radially opposite from the first joining surface and spaced therefrom, such that a groove is defined between the first and second joining surfaces. According to the invention, the radially intermediate joint (160) is formed by an insert ring made from a high strength material that is pressed into the groove. The invention also relates to a corresponding method of manufacturing a wheel bearing unit.Type: ApplicationFiled: September 14, 2010Publication date: June 13, 2013Inventors: John van de Sanden, Cornelius Petrus Antonius Vissers, Victor Haans, Andreas Knopf, Paolo A.

ASSEMBLY COMPRISING A RADIALLY INTERMEDIATE JOINT AND CORRESPONDING METHOD OF JOINING TWO COMPONENTS
Publication number: 20130145599Abstract: An assembly comprising a first component joined to a second component by means of an intermediate joint is provided. The first component has a first joining surface arranged coaxially and spaced in a juxtaposition around a second joining surface of the second component, such that a groove is defined between the first and second joining surfaces. The groove comprises an arcuate section formed in that one of the first and second joining surfaces comprises a concave portion and the other of the first and second joining surfaces comprises a convex portion, radially opposite from the concave portion. The intermediate joint is formed by an insert ring, made of a high strength material, pressed into the groove and deformed such that material of the insert ring fills the concave portion and surrounds the convex portion. Consequently, the first and second components are locked relative to each other in both axial directions.Type: ApplicationFiled: May 28, 2010Publication date: June 13, 2013Inventors: John van de Sanden, Cornelius Petrus Antonius Vissers, victor Haans, Maarten Noordman -
