Introduction: Exploring the core mystery of disc spring
Disc springs, commonly known as disc springs, are essential mechanical components renowned for their high stiffness, superior vibration damping capabilities, and compact axial dimensions. These features make them widely used in aerospace, defense, automotive, and precision machinery industries. As a leading manufacturer specializing in disc spring technology, Jiangsu Sunzo spring Technology Co., Ltd. provides comprehensive analysis of key parameters and technical standards for disc springs, empowering engineers to make precise design decisions.
To accurately design and select disc springs, it is essential to understand their core parameters. These parameters directly determine the load-deformation characteristics and service life of the disc springs.
Inner cone height (h₀): This is a crucial parameter of the disc spring. The calculation formula is `h₀ = H₀ – t` (unit: mm). It directly affects the stiffness characteristics of the disc spring and is the basis for the technical calculation of the disc spring.
Dimensional accuracy and fit standard:
H 12(13): The outer diameter D is specified with permissible deviations under the basic shaft system, where 12 and 13 denote different tolerance grades.
h 12(13): The representative inner diameter d is subject to permissible deviations under the basic hole system.
Understanding these tolerance standards is crucial to ensure the precise fit and stable performance of disc springs in components, as stipulated in the national standard for disc springs (GB/T 1972).
According to different section coefficient (h₀/t) and the ratio of outer diameter to thickness (D/t), the international disc spring is divided into three standard series, A, B, C, to meet different load and deformation requirements.
A Series (h₀/t ≈ 0.4, D/t ≈ 18):
Features: The spring is relatively "hard", bearing capacity is strong, but the deformation is small.
Application: Suitable for compact space and high pre-tensioning force.
B Series (h₀/t ≈ 0.75, D/t ≈ 28):
Features: The characteristic curve is close to linear, which is the most widely used general series, taking into account the load and deformation.
Application: Suitable for most conventional buffer, vibration absorption and energy storage occasions.
C Series (h₀/t ≈ 1.3, D/t ≈ 40):
Features: The spring is relatively "soft", the deformation is large, can absorb more energy.
Application: Suitable for cushioning and vibration isolation systems requiring large deformation and soft characteristics.
