    Description

    Sign

    Flat pad is mainly made by stamping iron plate, and its shape is usually a flat washer with a hole in the middle. Flat washers are typically thin pieces of various shapes used to reduce friction, prevent leakage, isolate, prevent loosening, or distribute pressure.

     

    The working principle of a flat pad is mainly reflected in the following aspects:

    Increase contact area: The flat pad disperses pressure by increasing the contact area between the screw and the machine, preventing softer components from being crushed. This design is particularly suitable for situations where one of the connecting components is soft and the other is hard and brittle. By increasing the contact area and dispersing pressure, it protects the softer components from damage

    Prevent damage: When using flat pads, the order of "one spring pad, one flat pad" must be followed, that is, the flat pad is adjacent to the machine surface, and the spring pad is between the flat pad and the nut. This can eliminate the damage caused by the spring pad to the machine surface when removing screws, and protect the machine surface from damage

    Auxiliary disassembly: In some cases, such as when bolts often need to be disassembled, using flat pads can simplify the disassembly process and make it more convenient. This is because the design of the flat pad helps reduce friction and resistance during disassembly, making the disassembly process smoother

    Reduce compressive stress: When the bolt strength is high and the compressive stress of the connected part is relatively low, using a flat washer can reduce the compressive stress on the pressure bearing surface of the connected part. This design helps to balance pressure distribution and avoid component damage caused by excessive local pressure

    Purpose:

    Flat pad is an inelastic gasket that can withstand high pressure. Its main function is to increase the contact area between bolts and connectors, disperse pressure, and protect the machine from damage. In addition, flat pads can also be used to compensate for uneven or non perpendicular connection surfaces. Flat pads are commonly used in situations where the load is small and does not withstand vibration loads, such as machine tools, light industrial machinery, ordinary household appliances, toys, etc. ‌

      Double layered self-locking washer Stainless steel Double disc self-locking washer

      ‌A double-stacked self-locking washer is a special mechanical connector designed to prevent bolts from loosening, especially in high-vibration or high-load environments.It consists of two spring washers nested inside each other in an S-shaped configuration. The outer spring washer has ends that bend inwards, while the inner spring washer has ends that bend outwards, creating a two-way self-locking feature.The working principle of this washer is based on elastic deformation. When placed between connecting parts, the inner curved part of the outer spring ring interlocks with the outer curved part of the inner spring ring, creating a locking force that prevents the connecting parts from loosening under vibration or load.The advantages of the double-stacked self-locking washer include high reliability, easy installation, and a wide range of applications.It is suitable for various mechanical connections, such as threaded connections and pin connections, and is widely used in industrial production and machinery manufacturing, especially in the automotive manufacturing process, where it is often used to connect engine and chassis systems to improve the safety and reliability of the car.
