The invention relates to a method for assembling at least one ring cooperating by shrinkage with a shrink fitting surface of a component defining a reference axis and having a through axial cavity, the shrink fitting surface being radially remote from the reference axis, the invention relates to a method for assembling a component having a free upper end and an inner wall extending radially towards the reference axis around the reference axis and axially while defining at least a portion of an axial cavity, the method comprising: a step of forming an axially extending spline on the inner wall; a step of shrinking the ring on the shrink fitting surface of the component such that the lower lateral surface of the ring abuts against the shoulder of the component; the assembly method comprises, after the step of forming the spline and before the step of shrinking the ring onto the cold shrink fitting surface of the component, a step of radially elastoplastically expanding the upper portion of the component, which causes a portion of the cold shrink fitting surface and the spline to widen, followed by the shrinkage of the ring on the cold shrink fitting surface causing the upper portion to deform, a portion of the spline is brought close to the reference axis.

    本发明涉及一种用于组装至少一个通过收缩与部件的冷缩装配表面配合的圈的方法,部件限定参考轴线且具有贯穿轴向腔,冷缩装配表面径向远离参考轴线,部件具有自由上端、及围绕参考轴线延伸径向朝向参考轴线且沿轴向延伸同时界定轴向腔的至少一部分的内壁,该组装方法包括:在内壁上形成轴向延伸的花键的步骤;在部件的冷缩装配表面上收缩圈使得圈的下横向面抵靠部件的肩部的步骤;该组装方法包括:在形成花键的步骤之后并且在将圈收缩到部件的冷缩装配表面上的步骤之前,部件的上部径向弹塑性扩张的步骤,其导致冷缩装配表面和花键的一部分变宽,随后圈在冷缩装配表面上的收缩导致上部变形,使得花键的部分接近参考轴线。
