Professional Operation Guide: Standard Installation and Disassembly Procedures for Disc Spring and Wave Spring
The installation and removal of disc springs and wave springs are critical operational procedures that directly impact their performance and service life. Improper handling may lead to premature spring failure, equipment malfunctions, or even safety incidents. Based on safety engineering principles and extensive field experience, Jiangsu Sunzo Spring has developed a standardized Operating Procedure (SOP) to minimize operational risks associated with elastic components.
Work environment: Ensure the work area is clean, well-lit, and has sufficient workspace.
Special tool setup:
Disc spring installation: dedicated mounting mandrel/guiding post, flat-end press-fit tool, torque wrench (for bolt pre-tightening application)
Spring installation: Install the guide sleeve and level the pressure block
Prohibited tools: Do not use non-specialized tools such as pliers or screwdrivers for forced installation.
Clean the mounting base: Thoroughly clean the contact surfaces with non-woven fabric and a dedicated cleaning agent to ensure there are no metal shavings, oil stains, or burrs.
Spring condition check: Inspect for transport damage prior to installation and verify that specifications match the drawings.
Direction of disc spring: Ensure the larger end (outer diameter end) faces the load-bearing support surface. For composite springs, follow the matching principle of 'large-to-large, small-to-small'.
Spring direction: Confirm the orientation of the wave crest, which should typically face the active end or the pressing surface.
Positioning assistance: Use guide pins or guide sleeves to ensure coaxiality of the spring during press-fitting
Uniform pressure application: Use a dedicated pressing tool to ensure even pressure distribution across the spring end face.
Speed control: The pressurized loading speed is controlled at 520 mm/s to avoid impact loading.
Stroke monitoring: Use displacement sensors or limit blocks to control the compression stroke. Overstroke installation is strictly prohibited.
Lubrication treatment: Apply special thread lubricant on threads and pressure-bearing surfaces
Torque control: A stepwise tightening method is employed, initially pre-tightened to 30% of the target torque, then increased to 60%, and finally reaching 100%.
Corner control: For applications requiring precise cornering, use an angle wrench for accurate control.
Energy confirmation: Ensure system pressure is fully released before disassembly
Safety precautions: Wear face protection and gloves to prevent sudden spring disengagement.
Bolt removal: Gradually loosen the bolts in a cross-symmetric sequence
Even unloading: Use a dedicated disassembly tool to evenly release pressure, preventing one-sided lifting.
Directional Marking: Clearly mark the orientation and position of the removed spring for easy reinstallation.
Parallelism inspection: Use a dial indicator to check the end face parallelism of the disc spring assembly, with a tolerance of ≤0.1 mm.
Height verification: Measure the free height of the spring assembly after installation and compare it with the design requirements.
Function testing: Perform no-load and load tests to verify installation effectiveness
Prevention of partial load: Ensure parallelism and cleanliness of installation surface
Overload Prevention: Strict Implementation of Torque/Stroke Control Standards
Injury prevention: Avoid direct contact between tools and the working surface of springs
