A square gasket is a thin, sheet-like part with a square shape. It is commonly used in various fields such as mechanical equipment, building structures, and electronic devices in conjunction with fasteners. Below is an in-depth introduction to square gaskets:

Definition

Square gaskets are primarily categorized as basic gaskets. They are used to adjust the level and clearance between parts during the assembly of mechanical components. By making these adjustments, they can suppress mechanical vibration and noise, prevent mechanical damage, and ensure stable operation.

Functions

• Pressure Distribution: Square gaskets can increase the contact area, thereby distributing the pressure applied by fasteners. This prevents the surface of the fastened parts from being damaged due to excessive local pressure.
• Prevention of Loosening: In environments with significant vibration, square gaskets can increase the friction between the fastener and the fastened part. This helps prevent the fastener from loosening due to vibration.
• Clearance Adjustment: They can be used to adjust the clearance between parts, ensuring precise assembly of equipment.
• Sealing Function: In situations where sealing is required, square gaskets can fill the tiny gaps between parts, preventing the leakage of liquids or gases.
• Surface Protection: They prevent direct contact between the fastener and the surface of the fastened part, avoiding scratches or wear on the fastened part.

Materials

Square gaskets are made from a variety of materials, including stainless steel, carbon steel, copper, plastic, and rubber. Gaskets made from different materials have distinct performance characteristics. For example, stainless steel gaskets have good corrosion resistance and high strength, making them suitable for a wide range of environments. Rubber gaskets, on the other hand, have good elasticity and are used for sealing and vibration damping.

Application Fields

• Mechanical Manufacturing: They are used in the assembly of various mechanical equipment, such as engines and gearboxes, to provide fastening, sealing, and vibration damping functions.
• Construction Industry: In building facades and steel structure connections, square gaskets are used to distribute the load of fasteners and protect the connection points.
• Electronic Devices: In the connection of electronic product casings and the fixation of internal components, they serve functions such as insulation, sealing, and cushioning.
• Automotive Manufacturing: They are used in the connection of fasteners in automotive engines, chassis, and other parts to prevent loosening and leakage.
• Aerospace: In aerospace equipment, square gaskets are used for the fastening and sealing of key components, ensuring the reliability and safety of the equipment.

Selection and Usage

When selecting square gaskets, it is necessary to consider factors such as material, size, thickness, and strength to meet the specific application requirements. During use, it is important to ensure that the gasket is correctly installed between the fastener and the fastened part, and that the fastening force is moderate to avoid damaging the gasket or the fastened part due to excessive tightening.

Square gaskets play a vital role in modern industry. Their diverse functions and extensive applications make them an indispensable mechanical component.
