Volute spring - Wikipedia

A volute spring, also known as a conical spring, is a compression spring in the form of a cone (somewhat like the classical volute decorative architectural ornament). Under compression, the coils slide past each other, thus enabling the spring to be compressed to a very short length in comparison with what would be possible with a more conventional helical spring.

There are two typical types of volute spring:

• The first has a shape for the initial spring steel (or other material for the wound spring) as a "V", with one end wider than the other
• The second is the double volute, having two "V" shapes facing away from each other, which forms a distorted cylinder having a wider diameter at the centre than at the ends, forming symmetric attachment points

Double volute springs can frequently be found as a component of garden pruning shears. Short posts anchored in each side of the handles, and inserted into each narrow end of the spring, keep the spring in position.

However, the applications of volute springs are not limited to such light-duty purposes as gardening shears. For example, volute springs are used to cushion the impact between railway cars and as a core element of the suspension system of Sherman tanks. A volute spring buffer device for railway cars was invented by John Brown in .[1]

Volute springs are a type of spring that is used in a variety of applications, including secateurs. They are made of spring steel and have a spiral shape. The coils of the spring are arranged in a volute, which is a spiral shape that resembles a snail shell. In this article, we will talk about volute springs for secateurs, hope it will help you know more about volute springs.

Why are volute springs important for secateurs?

Volute springs are important in secateurs because they provide the force that closes the blades. When the secateurs are closed, the volute spring is compressed. This is because the coils of the spring are forced closer together. When the secateurs are opened, the volute spring is released. This is because the coils of the spring are forced further apart.

The volute spring provides the force that closes the secateurs by pushing the blades together. The amount of force that the spring provides depends on the number of coils, the material of the spring, and the diameter of the spring.

Volute springs are a common type of spring that is used in a variety of applications. Here are some of the reasons why volute springs are important in secateurs:

• They provide the force that closes the blades. Without the volute spring, the secateurs would not be able to close properly and would be difficult to use.
• They are durable and long-lasting. Volute springs can last for many years with proper care.
• They are easy to maintain. Volute springs are easy to clean and can be easily replaced if they break.

What are the different types of volute springs used for secateurs?

There are two main types of volute springs used in secateurs: single-coil volute springs and double-coil volute springs.

• Single-coil volute springs: Single-coil volute springs are the most common type of volute spring used in secateurs. They are made of a single coil of spring steel that is wrapped around a mandrel. The spring is then compressed and held in place by a retaining ring or clip.
• Double-coil volute springs: Double-coil volute springs are made of two coils of spring steel that are wrapped around each other. The springs are then compressed and held in place by a retaining ring or clip.

Double-coil volute springs are more expensive than single-coil volute springs, but they are also more durable. They are also more resistant to fatigue, which means that they are less likely to break over time.

The type of volute spring that is used in secateurs depends on the application. Single-coil volute springs are typically used in secateurs that are used for light-duty tasks, such as trimming flowers and shrubs. Double-coil volute springs are typically used in secateurs that are used for heavy-duty tasks, such as pruning trees.

Conclusion

Volute springs are a durable and long-lasting type of spring that can last for many years with proper care. However, they can be damaged if they are overloaded or if they are not used properly.

If you are using secateurs for heavy-duty tasks, it is important to use a volute spring that is designed for that type of use. You should also avoid overloading the secateurs, as this can damage the volute spring. If you think that the volute spring in your secateurs is damaged, you should replace it as soon as possible. A damaged volute spring can make it difficult to use the secateurs and can also be dangerous.

Overall, volute springs are an important part of secateurs and help to ensure that they work properly. By following these simple tips, you can help to extend the life of your volute springs and keep your secateurs in good working order.
