Umbrella compression springs are specialized helical springs designed to provide a unique combination of flexibility, долговечность, and space efficiency. Known for their distinctive "umbrella-like" форма, these springs are widely used in applications requiring consistent force distribution and load resistance within a confined space. If you’re looking to source custom umbrella compression springs from China, this guide provides everything you need to know, from specifications and materials to sourcing tips and top suppliers.
What is an Umbrella Compression Spring?
An umbrella compression spring is a variation of a standard compression spring, but with a distinctive profile where the spring diameter tapers towards one or both ends. The umbrella-like shape enables the spring to compress into a smaller space, making it ideal for compact applications.
Ключевые особенности:
- Conical Design: Tapered ends allow for reduced height when fully compressed.
- Load Distribution: Ensures even force and load management.
- Компактность: Space-saving design suitable for tight spaces.
- Customizable: Fully adaptable to meet specific requirements.
Applications of Umbrella Compression Springs
Umbrella compression springs are used across diverse industries due to their adaptability and efficient design. Some common applications include:
1. Автомобильная промышленность:
- Used in clutches, тормоза, and suspension systems.
2. Аэрокосмическая промышленность:

- Grades include SS302, SS304, and SS316.
2. Музыкальный провод:
- High-tensile strength and excellent elasticity.
- Best for applications requiring frequent compression.
3. Углеродистая сталь:
- Affordable and durable, but less corrosion-resistant.
- Suitable for indoor or controlled environments.
4. Alloy Steel:
- Offers superior strength and wear resistance.
- Used in heavy-duty or high-temperature applications.
5. Фосфорная бронза:
- Combines good conductivity and corrosion resistance.
- Ideal for electrical and marine applications.
Customization Options for Umbrella Compression Springs
When ordering custom umbrella compression springs, consider the following specifications:
1. Размеры:
- Диаметр проволоки: Thickness of the spring wire.
- Внешний диаметр: Maximum width of the spring.
- Внутренний диаметр: Clearance space required for the spring's core.
- Свободная длина: Length of the spring in an unloaded state.
- Твердая высота: Height when the spring is fully compressed.
2. Весенняя ставка:
- Defines the force required to compress the spring by a unit distance (Н/мм).
3. Maximum Load:
- The highest load the spring can sustain without deformation.
4. Taper Ratio:
- Determines the degree of tapering from one end to the other.
5. Finish Options:
- Zinc Plating: Protects against rust and corrosion.
- Black Oxide: Reduces glare and provides a sleek finish.
- Пассивация: Enhances corrosion resistance for stainless steel.
6. Допуски:
- Specify dimensional tolerances to ensure precision for your application.
