A self-locking nut is a type of nut that can self lock by friction. The following is a detailed description of self-locking nuts:
1, Working principle
The main working principle of self-locking nuts is to achieve self-locking through friction. Its embossed teeth will be pressed into the preset holes of the sheet metal, and the diameter of the preset holes is usually slightly smaller than that of the rivet nut. When tightening the nut, the locking mechanism will lock the ruler body or bolt, preventing the ruler frame or nut from moving freely, thus achieving the purpose of locking. When the nut is loosened, the locking mechanism will disengage from the ruler or bolt.
2, Type and Function
• Type: There are various types of self-locking nuts classified by function, including those with nylon rings, those with neck closures (such as trapezoidal buckle nuts), and those with metal anti loosening devices. They all belong to effective torque type anti loosening nuts.
Function: The main function of self-locking nuts is to prevent loosening and earthquake resistance, especially suitable for special occasions and high vibration environments.
3, Application and advantages
Application: Self locking nuts are widely used in various mechanical and electrical products, especially in fields such as aerospace, aviation, tanks, mining machinery, automotive transportation machinery, agricultural machinery, textile machinery, etc. Its anti vibration and anti loosening performance is much higher than other anti loosening devices, and its vibration life is several times or even tens of times longer.
• Advantages:
High reliability: self-locking nuts can prevent nut loosening caused by vibration or impact.
Easy to install: The design of some self-locking nuts (such as spring clip self-locking nuts) simplifies the installation process.
Strong adaptability: able to work stably under different temperature and pressure conditions, such as the double ear sealed floating self-locking nut suitable for a temperature range of -50~100 ºC and a working pressure not exceeding 2atm.
4, Special type
High strength self-locking nut: With high strength and reliability, it is commonly used in fields such as road construction machinery, mining machinery, and vibration machinery equipment.
Nylon self-locking nut: It is a new type of high anti vibration and anti loosening fastening part, with a compact structure and reliable sealing, especially suitable for environments with sealing requirements.
Shibiluo self-locking nut: Its female thread has a 30 degree wedge-shaped slope at the bottom, which can generate strong locking force and effectively prevent loosening.
In summary, self-locking nuts play an important role in various industrial applications due to their unique self-locking mechanism and superior performance.
