Abstract:
A method of manufacturing a mechanical part of the present invention includes a first process of forming, by performing a folding processing to an end portion of the material, a portion to be processed having a structure, in which a plurality of layers respectively having a thickness corresponding to a plate thickness of a material overlap each other, in the material such that a plate thickness direction of the layer is orthogonal to a plate thickness direction of the material; and a second process of changing, by performing a forging processing to the portion to be processed, a shape of the portion to be processed to a target shape while press-welding the layers of the portion to be processed to each other by plastic deformation.
Abstract:
Letting the direction in which a first member (10) and a second member (12) are arranged be a first direction and a direction orthogonal to the first direction be a second direction, this welding structure has: a pressure fit part (26); a first hollow part (32); a second hollow part (34); a first weld bead (20) formed between an end, which is on a joining part of the first member (10) and the second member (12) on one side in the second direction, and the first hollow part (32) by welding the first member (10) and second member (12) in a state in which the outside and the second hollow part (32) are linked; a second weld bead (22) formed between an end, which is on a joining part of the first member (10) and the second member (12) on the other side in the second direction, and the second hollow part (34); and a cutout groove (42) linking the first hollow part (32) and the second hollow part (34).
Abstract:
It is a task of the present application to provide a butt position detecting method for a weld joint and a butt position detecting device for a weld joint that can detect a position of a butt portion between both members with high accuracy while reducing costs, and a manufacturing a weld joint that carries out the butt position detecting method. Thus, according to one aspect of the invention, in a butt position detecting method for a weld joint, when an arrangement direction of a first member and a second member is defined as a first direction, and a direction that is perpendicular to the first direction is defined as a second direction, the first member has a corner portion and a chamfer portion, and a two-dimensional displacement sensor is arranged at a position offset from the butt portion toward the first member side in the first direction, and such that an angle θs at which the second direction and an optical axis direction of irradiation light of the two-dimensional displacement sensor intersect with each other and an angle θa at which the second direction and a formation direction of the chamfer portion of the first member intersect with each other satisfy a condition expression: 0°

Verfahren zum Verschweißen eines Tellerrads mit einem Ausgleichsgehäuse eines Getriebes, mit folgenden Schritten: - Herstellen eines Tellerrads, wobei das Tellerrad einen Tellerradflansch mit einer Flanschfläche aufweist, - Einsatzhärten des Tellerrads, - Gießen eines Ausgleichsgehäuses aus einem Gusseisenmaterial, wobei das Ausgleichsgehäuse eine Flanschschulter aufweist, - Herstellen eines Ausgleichsgehäuseflansches durch Drehbearbeiten der Flanschschulter, - Fügen des Tellerrads und des Ausgleichsgehäuses, wobei das Tellerrad mit seiner Flanschfläche gegen die Flanschschulter gedrückt wird, - Verschweißen des Tellerradflansches mit der Flanschschulter mittels eines Hochenergiestrahls, wobei während des Schweißvorgangs der Schweißzone ein nickelhaltiger Zusatzwerkstoff zugeführt wird. Die Flanschschulter weist folgende Flanschbereiche auf: - einen sich einer Umfangsrichtung der Flanschschulter erstreckenden Steg, dessen Stirnseite nach dem Fügen an der Flanschfläche des Telleradflansches anliegt, - eine radial außerhalb des Stegs befindliche Flanschfläche, die von der Stirnseite des Stegs aus gesehen hinter der Stirnseite des Stegs liegt und die nach dem Fügen mit der Flanschfläche des Tellerradflansches einen ersten Spalt bildet, und - eine radial innerhalb des Stegs befindliche, sich in Umfangsrichtung der Flanschschulter erstreckende Ausnehmung, die nach dem Fügen einen zweiten Spalt mit der Flanschfläche des Tellerradflansches bildet.
Abstract:
A method of producing a mechanical face seal, the method including a step of obtaining a cast or wrought substrate part (400) having an inner diameter, outer diameter, and a planar surface (440). The method may include an exposing step (330) to expose the planar surface (440) to a laser (1000). The method may further include a supply step to supply a coating material (1150) to a location at or near the laser (1000) on the planar surface (440) in order for the coating material (1150) to form a metallurgical bond with the substrate part (400).
