A wave spring, also known as a wave washer, is a type of mechanical spring that is made up of a corrugated shape, similar to a wave. These types of springs are known for their ability to provide a high force within a small space, making them ideal for use in various applications. One type of wave spring is the overlap wave spring, which is known for its unique design and high force capabilities.
The design of overlap wave spring
The overlap wave spring is made up of two waves that overlap each other. This design allows for a larger deflection than a traditional wave spring, which means it can provide a higher force within the same amount of space. This makes the overlap wave spring an ideal choice for applications where space is limited. The overlap wave spring is also known for its ability to provide a consistent force throughout its entire deflection range, which is another advantage over traditional wave springs.
Application of overlap wave spring
One of the most common applications of overlap wave springs is in the automotive industry. They are often used in transmission systems, where they provide a high force in a small space, and also in the brake systems, where they are used as a return spring. Overlap wave springs are also used in the aerospace industry, where they are used in landing gear systems and in other systems where high forces are required in a limited space.
Another application of overlap wave springs is in the industrial sector, where they are used in various machines and equipment. For example, they are used in pneumatic and hydraulic cylinders, where they provide a consistent force and act as a return spring. They are also used in pumps, valves, and other types of machinery.
In order to properly design and install overlap wave springs, it is important to consider the desired load and deflection range for the application. The spring rate, which is the amount of load required to compress the spring a certain amount, must also be taken into consideration. The spring rate can be adjusted by changing the number of turns in the wave or by changing the material of the spring. It’s also important to ensure that the overlap wave spring is properly aligned with the load to ensure optimal performance.
Factors to consider when choosing an overlap wave spring
When choosing an overlap wave spring, some factors to consider include:
- Load capacity: The amount of force that the spring will need to support.
- Deflection: The amount of movement or displacement that the spring will need to withstand.
- Space constraints: The available space in the application and the size of the spring.
- Durability: The expected lifetime of the spring and the environment it will be used in.
- Cost: The cost of the spring and any associated installation or maintenance costs.
- Material: The material of the spring should be chosen for the specific application and its environment.
- Compatibility: It should be compatible with the surrounding components and equipment.
- Temperature range: The range of temperatures that the spring will be exposed to and its impact on the spring’s performance.
- Wave type: The design of the wave spring, whether it is an overlap wave spring or a non-overlap wave spring.
- Radial or axial load: The type of load the spring will be subjected to, radial or axial, and its impact on the spring’s performance.
Advantages of using overlap wave spring
There are several advantages to using overlap wave springs:
- High load capacity: Overlap wave springs have a high load capacity relative to their size and thickness, making them a space-efficient option.
- Low compression height: They have a low compression height, which can be beneficial in applications where space is limited.
- High deflection: They can handle high deflection, which means they can withstand more movement or displacement than other types of springs.
- Low cost: They are relatively low cost compared to other types of springs.
- Low solid height: They have a low solid height, which makes them suitable for use in applications where space is limited.
- Wide range of materials: They are available in a wide range of materials, including stainless steel, high-carbon steel, and various alloys, which makes them suitable for different environments and conditions.
- Versatile : They can handle radial and axial loads, and can be used in a wide range of applications.
- Durable: They are durable and have a long lifespan, which can save costs over time.
In conclusion, overlap wave springs are a type of mechanical spring known for their high force capabilities and unique design. They are commonly used in the automotive and aerospace industries, as well as in the industrial sector. With proper design and installation, they can provide consistent force in limited space which makes them a perfect fit for various applications.
