    • An improved method of holding a key (20) in a keyway (31) includes the steps of: forming an elongated keyway in the member, the member having at least one sharp corner (34) facing into the keyway adjacent either end thereof; forming a key (20) to fit in the keyway, the key being so dimensioned, proportioned and configured that the part of the key immediately adjacent each sharp corner will be recessed with respect to the surface of the member at the corner; placing the key in the keyway; and plastically deforming portions (40) of the member at the sharp corners into the keyway so as to permanently hold the key in the keyway.
    • 在键槽(31)中保持键(20)的改进方法包括以下步骤:在构件中形成细长的键槽,所述构件具有至少一个尖锐的角部(34),所述尖锐的角部(34)面向邻近其任一端的键槽; 形成键(20)以配合在键槽中,该键的尺寸,比例和构造使得紧邻每个锐角的键的部分将相对于在角部处的构件的表面凹陷; 将键放在键槽中; 并且使所述构件在所述尖角处的所述部分(40)变形成所述键槽,以将所述键永久地保持在所述键槽中。
