Why can round nuts maintain a more stable locking effect under vibration conditions?

Round nuts maintain a more stable locking effect under vibration conditions, mainly due to their unique design and locking mechanism.

Self-locking device: Round nuts are usually designed with a self-locking device inside. This device uses a specific structure or material to generate a continuous locking force after the nut is tightened, making the connection between the nut and the bolt stronger. This locking force effectively prevents the nut from loosening even under vibration conditions.

Enhanced friction: The connection between round nuts and bolts is not just a simple threaded connection, but also enhances friction by increasing the contact area and adopting a special thread shape. This enhanced friction can resist external forces caused by vibration and maintain the stability of the connection.

Use of fitting parts: Round nuts are often used together with fitting parts such as stop washers. These fitting parts can further increase the locking force and improve the reliability of the connection. The inner tongue of the stop washer is inserted into the groove on the shaft, and the outer tongue is inserted into the groove of the round nut, forming a stable locking structure.

Material selection: The material selection of the round nut is also an important factor in ensuring its stable locking effect. Usually made of materials with high strength, high wear resistance and high corrosion resistance, these materials can withstand the impact and friction caused by vibration and maintain a long-term locking effect.

Structural optimization: The structural design of the round nut has been optimized to better adapt to the vibration environment. For example, by increasing the thickness of the nut, optimizing the thread angle, etc., the nut's ability to resist loosening under vibration conditions can be improved.

The round nut can maintain a more stable locking effect under vibration conditions, which is mainly due to its unique self-locking device, enhanced friction, use of mating parts, high-quality material selection and optimized structural design. These characteristics make round nuts ideal where resistance to vibration and shock is required.
