Screw connection is a kind of mechanical connection through thread matching, which has the characteristics of simple structure, removable, adjustable fastening force, etc., so it is widely used in the engineering field.
First, the basic principle of screw connection
1. Thread principle: Thread is a spiral geometric shape, through the thread to achieve the connection of the screw. Common thread types include internal and external threads, which are connected by the inclined friction and pressure of the threads.
2. Principle of fastening force: The key to screw connection is to generate enough fastening force to closely combine the connecting parts. The rotation of the screw can create a tension force that fastens the connecting parts together.
Second, the classification of screw connection
1. Classification by thread type: Common thread types include metric thread, inch thread and metric thread, etc. Different types of threads are suitable for different application scenarios.
2. By material classification: screws can be classified according to different materials, common materials include steel, stainless steel, aluminum alloy, etc., different materials have different mechanical properties and corrosion resistance.
Third, the advantages of screw connection
- Simple structure: Screw connection structure is simple, easy to install and disassemble.
- Adjustability: The screw connection can be rotated to adjust the fastening force to meet the needs of different applications.
- High reliability: Screw connections provide high connection strength and stability.
Fourth, the application of screw connection
1. Mechanical manufacturing: Screw connection is widely used in the field of mechanical manufacturing, such as automotive, aerospace, mechanical equipment and so on. It can be used to connect parts and fixed structures to ensure the normal operation of mechanical equipment.
2. Construction engineering: Screw connection also has important applications in construction engineering, such as steel structure connection, construction equipment installation, etc. It can provide a reliable connection to ensure the stability and safety of the building structure.
3. Electronic products: Screw connection plays a key role in the assembly of electronic products, such as computers, mobile phones, home appliances, etc. It can connect electronic components to ensure the normal operation of electronic products.
