Washer with detailed explanation of gasket
Washer with detailed explanation of gasket
In the industrial field and even in our life, the application of washers is everywhere, and their shapes are different. According to its types, there are flat washers for the purpose of increasing the stress area, spring washers for preventing loosening, locking washers specially used for high-load vibration and sealing washers for sealing, etc. These washers have different working principles, installation methods and usage methods in practical application.
What are the types of washers?
Common washers include flat washers, spring washers, anti-loosening washers, sealing washers, etc.
1. What is the flat washer like? (Figure 1)
The flat washer is mostly made of stainless steel 304, and the main parameters are inner diameter, outer diameter and thickness. Flat washers generally belong to standard parts in the category of fasteners, such as a series of models such as ordinary flat washers DIN 125A/ISO 7089/GB 95.
2. What is a spring washer? (Figure 2)
After the connecting pair is tightened, the spring washer relies on the reaction force of the washer product itself to enhance the axial tension between the connecting pairs and further increase the friction force to prevent loosening.
Common spring washers mainly include heavy spring washers DIN 127A/GB 7244, standard spring washers DIN 127B/GB 93, saddle spring washers DIN 128A/GB 7245, corrugated spring washers DIN 137A/GB 860 and DIN 137B/GB 955, conical elastic washers DIN 6796/ISO 10670 and other product standards.
3. What is an anti-loosening washer?
As the name implies, the anti-loosening washer is a washer that locks the connecting pair. This paper introduces several kinds of stop washers mainly fixed by machinery and washers that achieve locking function by increasing friction.
Stop washer (as shown in Figure 3): Relying on the mechanically fixed stop washer, the relative movement between the thread, the connected piece and the thread connecting pair can be prevented to achieve the purpose of preventing loosening. There are various forms of stop washers, mainly including single-ear stop washers, binaural stop washers, inner tongue stop washers, outer tongue stop washers, etc.
Lock washer (as shown in Fig. 4): This kind of anti-loosening gasket mostly achieves the locking purpose by increasing friction force, etc. The main common ones are SK tooth surface from Lock pad Circle and Double-sided locking washers and other types.
There are many types of washers. Different materials, different modes of action and different application scenarios require different types of washers. For more details, please contact our company. Professional engineering will provide you with professional fastening schemes!
