Abstract:
본 발명은 레이저를 이용한 철도차량용 기어커플링의 기어치형 형성방법에 관한 것으로, 그 목적은 기어 치면(齒面)의 경도를 높여 기어부위의 마모는 최소화하되, 정확한 치차각으로 동력전달 효율을 극대화하는 것이다. 이를 위한 본 발명에 따른 레이저를 이용한 철도차량용 기어커플링의 기어치형 형성방법은, 레이저장치에서 조사(照射)되는 레이저 비임에 의해 기어치형(齒形)이 형성되는 것이다. 이에 따라, 기어 치면부위의 경도를 높이므로 기어부위의 마모는 최소화함과 동시에 정확히 형성된 치차각에 의해 동력전달 효율을 극대화시킨 이점이 있다.

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).
Abstract:
A method of manufacturing a gear (20") includes providing a rim gear (14"), a hub (10") and a core (12"), wherein the core (12") is annular and has a core forging temperature below a hot hardness temperature of the rim gear (14") and the hub (10"). The rim gear (14") and the hub (10") are rotated about an axis relative to the core (12"). During the relative rotation, the rim gear (14") and the hub (10") are in contact with the core (12") to generate friction heat to raise an interface temperature of the core (12") to the core forging temperature. The hub (10") is driven into the core (12") to upset a first portion of the core (12") into an outer annular groove defined in a first faying surface of the hub (10"). The rim gear (14") is driven over the core (12") to upset a second portion of the core (12") into an inner annular groove defined in a second faying surface of the rim gear (14").

Abstract:
The purpose of this double sided welding method is to improve product precision. When welding from both sides of a joining part where a first member and a second member, which are the objects being joined, face each other is performed by a first weld performed from one side and a second weld performed from the other, opposite side from that first weld, sandwiching that joining part, a heat quantity adjustment, that adjusts the quantity of heat input to the joining part for the second weld, which is performed after the first weld, is carried out such that an amount of welding distortion that is the objective arises.
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 ¸s 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 ¸a 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°
