Introducing a comprehensive overview of our state-of-the-art elastic pins.
Structural Features: Our elastic pin, often referred to as a spring pin, showcases a cutting-edge design with a headless, hollow cylindrical shape. It features axial grooves and chamfered ends, ensuring optimal performance and seamless application in various assemblies.
Working Principle: Ingeniously engineered, the outer diameter of the elastic pin is slightly larger than that of the assembly hole. This deliberate design choice ensures that upon installation, the pin exhibits elastic deformation due to the compression exerted by the hole's inner wall. This results in a contraction from the outside to the inside, which in turn creates a robust and tight fit, locking the components securely in place.
Material Selection: Our elastic pins are crafted from a range of premium materials, including top-tier spring steels like 50Mn and 65Mn, as well as stainless steel variants 304 and 201. We also offer options in 60Si2MnA, carbon steel, alloy steel, and copper, providing versatility for diverse applications and ensuring enhanced durability and reliability.
• Classification Method
Our product line offers an array of options, categorized by appearance: choose from the sleek straight groove shape, the sophisticated rolled shape, or the innovative toothed elastic cylindrical pin, each designed to meet specific functional demands.
According to shear load, our elastic cylindrical pins are expertly classified: straight groove and toothed versions are available in both light and heavy-duty options, while rolled elastic pins can be selected in light, standard, and heavy-duty types, catering to varying shear load requirements.
• Main Role
Connection Fixation: Through innovative design, our elastic pins create friction between the pressure from their elastic deformation and the hole wall. This robust interaction prevents any unwanted relative axial movement of the parts, ensuring a secure and lasting connection.
Bearing Axial Load: Our elastic pins are designed to endure axial loads with aplomb. They absorb a portion of the load through elastic deformation, effectively distributing it across the connecting parts and enhancing structural integrity.
Absorption of Vibration and Impact: Thanks to the inherent elasticity of the materials used, our pins adeptly deform when confronted with external vibrations or impacts. This characteristic significantly mitigates the impact on connected parts, extending their lifespan and maintaining performance.
Simplified Assembly: Compared to traditional connection methods like bolts and screws, our elastic pins offer a streamlined, straightforward design. This simplicity translates to effortless installation and markedly improved assembly efficiency, saving time and reducing labor costs.
Easy to Disassemble: The innovative pressure dynamics involved in the assembly of our elastic pins mean that disassembly is a breeze. They can be removed with ease, minimizing the risk of damage to components and ensuring maintenance is both quick and cost-effective.
