Product focus models: 001 099 series and 001 116 series (nominal outer diameter D ranging from 31.5 mm to 35.5 mm specifications)
In hydraulic locking systems of construction machinery, elastic components capable of delivering sufficient clamping force within extremely limited installation spaces are essential to ensure mechanisms remain securely locked in preset positions during hydraulic power interruptions or failures. The 31.5 mm to 35.5 mm outer diameter disc springs compliant with German industrial standard DIN 2093 are specifically designed and manufactured to meet these stringent engineering requirements. Featuring high load density and compact geometric dimensions, this series of disc springs serves as an ideal solution for critical safety applications requiring reliable locking performance.
Sample typical product parameters (represented by model 001 101)
Ø Nominal outer diameter D: 31.50 mm
Ø Inner diameter d: 12.20 mm
Ø Single sheet thickness t: 1.50 mm
Ø Free state height H₀: 2.35 mm
Ø The test load at compression to 25% of free height (corresponding to a deformation of 0.5875 mm) is approximately 1033 Newtons (N).
Ø The test load at 50% free height compression (corresponding to a deformation of 1.175 mm) is approximately 1912 Newtons (N).
In practical applications of hydraulic locking systems, multiple disc springs are typically assembled into spring assemblies through overlapping, stacking, or composite configurations. Serving as the core mechanical locking component, these assemblies consistently deliver stable and robust elastic preload forces. Their primary function is to immediately activate mechanical locking forces when associated hydraulic systems experience pressure loss due to faults, reliably maintaining the position of actuators (e.g., hydraulic cylinder piston rods) to prevent unintended movement or slippage. This significantly enhances overall system safety and reliability. Featuring superior material properties and precision manufacturing processes, this series of disc springs demonstrates exceptional load-bearing capacity and ample safety margins, making them ideal for hydraulic locking mechanisms, overload protection systems, and position retention devices in excavators, cranes, loaders, and other heavy-duty engineering machinery.
Key advantages of locking applications:
1. High locking force with safety and reliability: Provides significant elastic force per unit volume, ensuring decisive and effective locking action with sufficient safety margin.
2. High space utilization and compact structure: The flat disc-shaped design enables placement within cavities with strictly limited axial space, achieving miniaturization and integration of the device.
3. Excellent impact and fatigue resistance: Capable of withstanding dynamic loads and frequent loading/unloading cycles, adapting to harsh operating conditions such as vibrations and impacts commonly encountered in construction machinery.
