摘要 |
An improved tool for railway track adjustment machines is disclosed which may be made by processes forging, casting, and which includes a shaft and a blade manufactured as separate entities and force-fitted together. In making the tool the lower end of the shaft is formed so that it is able to be forced between flanges located on the rear side of the blade. This lower end preferably has a transverse cross section shaped as a trapezoid with an apex angle gamma and is upwardly and outwardly tapered at an angle alpha . The flanges located on the rear side of the blade are manufactured from the same piece of material as the blade and define a slot which opens upwardly and outwardly at an angle to the direction of the longitudinal axis of the tool and the symmetrical plane of the blade. A method the slot defined between the flanges has a transverse cross section which tapers inwardly at an angle delta and may be formed by deforming the blade. |
