The function introduction of spring washer and flat washer, understand in seconds after reading!

Recently I saw someone on Baidu asking what is the difference between the function of spring washers and flat washers? Today, I will give you a brief introduction to this aspect. I hope it can be helpful to everyone. Spring washers are mainly used to prevent loosening. Flat washers have no relaxation function. That is, the flat washers only increase the contact area, and the spring washers can prevent loosening. For example, the bolts connecting the motor and the frame should generally be equipped with spring washers. Spring washers, nuts will loosen. Generally, spring washers are installed on fasteners on equipment with vibration, and flat washers are generally not required on flanges. Adding or not adding a spring washer to the flange is related to the medium flowing in the pipeline. If it is easy to produce pulses, it is best to add a spring washer, and there are high-speed fluids. The diameter changes frequently, so don't generalize. On some valves, the stuffing box gland flange requires spring washers. All in all, flat washers increase the fastening contact area; spring washers can prevent loosening when used in places with vibration; fastened PVC flanges do not need to add spring washers. If you know that the main function of the spring washer is to prevent loosening, what is the specific use condition of the spring washer? The use condition of the spring washer is as follows: The application of the spring washer can be applied to the following four standards: Standard spring washer (GB93- 1987), light spring washers, (GB859-1987), heavy spring washers (GB7244-1987). The purpose of the spring washer: The device is installed under the nut to prevent the nut from loosening. It is stated in the national standard. Hexagonal slotted nuts are designed for use with bolts with holes at the end of the screw, so that the split pin can be inserted into the hole of the screw from the slot of the nut to prevent the nut from loosening automatically. It is mainly used in occasions with vibration load or alternating load. . Let me give you a simple example to illustrate the application of spring washers in actual use: This is my first screw assembly, the scientific name is hexagon socket bolt assembly. This kind of bolt is a common furniture fastening hardware connector. And it is a more important fastener, which is usually used for fixing the legs of a table. The rigorous hardware connection is usually as shown in the figure below. When used with the crossbar nut, spring washers are used. Because if there is a gap between the bolts and nuts once they are tightened, the furniture will inevitably shake after long-term use, which may cause the screws to loosen. In addition! Wood will shrink and shrink, the main function of spring washers is to give buffer space. From the design perspective, the spring washer (also called the spring washer) has a pre-tension, and after being compressed, it rebounds. In actual use, due to the characteristics of the thread, the nut can easily rotate in the direction of the spiral after being tightened, causing the nut to loosen. In order to solve this problem in the early days, spring washers appeared. Due to the pre-tension of the spring washer, after the nut compresses the spring washer, under the action of the pre-tension, the triangular screw buckle in the nut and the side of the triangular screw buckle of the bolt are tightly attached to each other. Under the action, the nut no longer appears loose. The ordinary washer (also called round hole washer or flat washer or ordinary washer) is a support under the pretension of the spring washer, which increases the pressing area of u200bu200bthe pretension of the spring washer. The main function of the spring washer is introduced here, and I hope this article can be helpful to everyone.
