What is the difference between spring washers and ordinary washers?

From the design perspective, the spring washer (also called the spring flat 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 flat washers appeared. Due to the pre-tension of the spring flat 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, and the friction Under the action of force, the nut will no longer be loose. Spring washers are used to prevent loosening. For example, the bolts connecting the motor and the frame should generally be equipped with spring washers. Because the motor vibrates without spring washers, the nuts will loosen. The fasteners on the vibrating equipment are equipped with spring gaskets, and the flanges generally do not need to add gaskets! The addition of spring gaskets on the flange is related to the medium flowing in the pipeline. If it is easy to produce pulses, it is best to add spring gaskets, as well as high-speed fluids, and the diameter changes frequently. Do not generalize. On some valves, the stuffing box gland All flanges need to add spring gaskets. Spring gaskets are included in the automatic selection of quick, easy and excellent. The ordinary washer (also called round hole flat washer or flat washer or ordinary flat washer) is a support under the pretension of the spring flat washer, which increases the pressing area of u200bu200bthe spring flat washer's preload. Generally speaking, spring flat washers and ordinary washers are used together, and it is unreasonable to use ordinary washers alone. Of course, the design and actual needs of individual applications are not excluded. For example, when the plastic shell of electrical appliances is screwed with self-tapping screws, the use of ordinary washers alone is just to increase the force area.
