保险丝安装与技术

A.General

概述

Appropriate diameter lockwire (specified in Aerospace Standard 567) is installed using the following techniques and techniques:

采用以下技术安装符合航空标准567规定的适径保险丝：

• Install lockwire so that loosening tendency of a part causes tightening of the lockwire.
• 安装保险丝时，应使零件松动趋势导致保险丝收紧。
• Ensure lockwire consists of two strands twisted together unless otherwise specified.
• 除非另有规定，保险丝应由两股绞合线组成。
• Pull lockwire taut while twisting and have approximately eight to ten turns per inch without being overstressed.
• 扭转保险丝时保持绷紧状态，每英寸约扭转八至十圈，避免产生过度应力。
• Install lockwire so no wear or excessive load to part is experienced.
• 安装保险丝时确保零件无磨损或承受过载。
• Cut lockwire at the end of a series, leaving at least three full twists. Bend the end to eliminate safety hazard.
• 保险丝在系列末端剪断时，需保留至少三圈完整扭结。弯折末端以消除安全隐患。

B.Lockwiring Examples

保险丝安装示例

Examples of lockwiring are shown in Figure 508 and methods are explained as follows:

图508展示保险丝安装示例，具体方法说明如下：

• Methods 1 and 2 apply to bolts and drilled head screws. The first section of lockwire is twisted clockwise and the second section is twisted counterclockwise.
• 方法1和2适用于螺栓及带钻孔螺钉。首段保险丝顺时针拧紧，次段逆时针拧紧。
• Methods 3 and 4 apply to a single drilled head screw or a plug lockwired to a drilled point.
• 方法3和4适用于单个带钻孔螺钉或保险丝固定于钻孔端的堵盖（螺栓）。
• Method 5 applies to an adjustable connecting rod.
• 方法5适用于可调连杆。
• Methods 6 through 10 apply to various types of tubing assemblies.
• 方法6至10适用于各类管组装。
