Introduction to the Advantages of Elastic Cylindrical Pin Structures

　　ElasticityCylindrical pinWhat material is good? Introduction to structural advantages

　　Elastic cylindrical pins, also known as spring pins, are headless hollow cylinders with axial slots and chamfered ends. Used for positioning, connecting, and fixing parts; they need to have good elasticity and shear resistance. The outer diameter of these pins is slightly larger than the diameter of the mounting hole.

　　Elastic cylindrical pins have a simple structure, good neutrality, high load-bearing capacity, good variable load and impact performance, but high requirements for the machining accuracy of the mating surface. The disassembly force is large, and the mating surface will be scratched, so it is a non-dismountable connection. When the interference fit is small or hydraulic disassembly is used, the connection is also dismountable. Since the cylindrical pin has no elasticity, the hole accuracy should be improved as much as possible during installation to better match the cylindrical pin. The process requirements of elastic cylindrical pins can be appropriately relaxed.

　　The advantages of elastic cylindrical pins are different. Cylindrical pins require relatively high tolerances and precision. The advantages of cylindrical pins are better stress bearing and easier production. The production of elastic cylindrical pins is more complex, but due to their good connection performance, they are also widely used.

The structure of the elastic cylindrical pin is very simple, the processing and manufacturing are very easy, and it is very convenient to disassemble and replace during use.

　　When solid pins are used in dynamic load applications, the rigidity of the solid pin often elongates and damages the hole, leading to permanent failure. In addition, using solid pins with lower material hardness can reduce damage to the main material, but it will also reduce the strength of the pin. As an alternative, heat-treated spring pins are generally stronger than solid pins, and their inherent elasticity maximizes the service life of assemblies in dynamic, heavy-load applications.
