The invention relates to a serrated fitting, and discloses a serrated fitting and a method for installing a fixed length roller tray segment across an integration zone of an aircraft fuselage. The serrated fitting includes a first surface for attachment to a fixed length roller tray segment. The serrated fitting also includes a serrated surface for engagement with a serrated plate attached to a floor beam of the aircraft. A fastener connects the serrated surface to the serrated plate and the floor beam through a pre-drilled hole in the floor beam. The pre-drilled hole is greater than the diameter of the fastener to accommodate a cumulative tolerance between joined fuselage sections at the fuselage integration zone.
本发明涉及锯齿状配件,公开了一种用于安装跨越飞机机身集成区的固定长度滚轮托盘段的锯齿状配件和方法。锯齿状配件包括用于附接到固定长度滚轮托盘段的第一表面。锯齿状配件还包括锯齿状表面,用于与附接到飞机的地板梁的锯齿状板接合。紧固件通过地板梁中的预钻孔将锯齿状表面连接到锯齿状板和地板梁。预钻孔大于紧固件的直径,以适应机身集成区处连结的机身区段之间的累积公差。
