The management of fastener form is used to enhance the impact analysis of equipment characteristics
Spring washers are a common and effective locking mechanism used in mechanical systems. If improperly installed or omitted, they can significantly compromise the reliability and lifespan of the equipment. For example, if the engine fan's fixing screw is not secured with a spring washer, the loose fan blade may scrape against the cooling water tank, while also damaging the drive shaft beneath the nut. In extreme cases, forgetting to use a spring washer could lead to a catastrophic failure, such as a vehicle rollover, which might even result in serious injury or loss of life.
Maintaining the original performance state of threaded fasteners is essential. This means that during maintenance, the type, position, and mechanical properties of the fasteners must remain consistent with the original design specifications. Using the correct fastener type ensures a reliable and detachable connection, which is crucial for mechanical maintainability. There are various types of fasteners designed for different functions, and one common issue during repairs is the lack of proper identification and handling.
After disassembling parts, it’s important to classify and store fasteners properly instead of discarding them carelessly. If fasteners are damaged, worn, or replaced without consideration, it can negatively impact the repair process and the system’s reliability. Some technicians may not pay attention to the thread type during assembly and may mix up different fasteners. For instance, using steel bolts with a different thread profile than required can damage aluminum alloy components. This often leads to stripped threads, which are difficult or impossible to repair. In some cases, reaming or tapping may be necessary, but this will inevitably reduce the component’s strength and service life.
Therefore, careful attention must be paid to selecting the correct fastener type during maintenance. Standard metric threaded fasteners include bolts, screws, and studs, each available in coarse and fine thread options. Bolts are widely used for general fastening, while stud bolts are preferred in situations where a bolt cannot be easily inserted, such as cylinder head bolts or half-shaft bolts. Coarse-threaded fasteners are typically used for non-moving parts, while fine-threaded ones are better suited for high-stress applications like connecting rods or drive shafts. They are also ideal for fastening thin-walled components to main structures, such as the clutch cover to the flywheel.
