Belleville springs, often referred to as disc springs, owe their name to the French engineer Belleville, who invented this unique spring. These springs take on a conical disc shape and can be utilized individually, in series, or in parallel. Disc springs are defined by four key parameters: outer diameter, inner diameter, thickness, and height.
Key Features of Belleville Springs:
Energy Storage: When subjected to a load, Belleville springs deform and store potential energy.
Energy Release: These springs can release stored energy when slack or reduced loads are encountered.
Uniform Stress Distribution: Belleville springs offer even stress distribution from the inner to outer edges, enabling precise control with low stroke and high compensation force.
Shock Absorption: Known for their remarkable shock-absorbing capacity, Belleville springs can withstand substantial loads with minimal deformation, making them an excellent choice for applications with limited axial space.
Versatile Combinations: Belleville springs can be used in various combinations, including superposition, inversion, and compound arrangements. This flexibility allows for a wide range of spring characteristics to suit specific applications. Mixing springs with different thicknesses and quantities further enhances versatility.
Variable Stiffness: By adjusting the height-to-thickness ratio of the conical disc or by combining discs of varying thicknesses or quantities, Belleville springs can exhibit different stiffness characteristics. This enables customization of spring behavior, offering linear, increasing, decreasing, or combined responses.
Ease of Maintenance: When damage occurs to a Belleville spring, only the affected disc needs to be replaced, simplifying maintenance and repair.
Concentric Force Transmission: Due to their annular shape, Belleville springs transmit force concentrically, ensuring even force distribution.
Applications of Disc Springs:
Belleville springs find widespread application in various industries, including:
Metallurgy: They serve as strong buffers and shock absorbers in heavy machinery.
Engineering: Commonly used in precision applications where energy storage and release are crucial.
Electric Power: They play a role in power generation and distribution equipment.
Machine Tools: These springs are components in machinery that demand precision and control.
Construction: Used in construction equipment and machinery.
Safety Valves and Pressure Reducing Valves: Employed to provide essential spring force in these types of valves.
