In-depth Analysis of Maintenance Technology: Engineering Implementation of Lubrication and Cleaning for Elastic Elements
In the maintenance systems for disc springs and wave springs, lubrication and cleaning are not only fundamental operations but also critical engineering processes that directly impact spring performance retention and lifespan extension. Based on material science and tribology principles, Jiangsu Sunzo Industry Engineering provides you with a scientific and actionable lubrication and cleaning implementation plan, helping you elevate maintenance from experience-based operations to engineering management standards.
The purpose of lubrication is not only to reduce friction, but also to establish a controllable interface environment.
High-frequency dynamic applications (e.g., clutch disc spring assemblies): It is recommended to use molybdenum disulfide (MoS₂)-based or graphite-based high-temperature greases. These lubricants maintain lubrication films under high contact pressures, exhibit excellent temperature resistance, and are particularly suitable for interface applications of laminated disc springs with micro-friction.
For static pre-tensioning or low-cycle applications (e.g., valve wave springs), apply rust-proof oil or light grease to provide corrosion protection and facilitate assembly.
Special environment applications:
Food/medical devices: Use NSF H1 food-grade grease
High-temperature environment (>200°C): Consider PTFE-based or composite ceramic lubricants
Vacuum environment: Use vacuum grease or solid lubricating film
Lubrication of disc spring composite interface: Apply a thin layer of lubricant uniformly on the conical surface of each disc spring. The amount should be sufficient to form a complete lubricating film without excessive overflow. The recommended dosage is 35 grams per square meter of contact area.
The spring is lubricated by a small amount of lubricant on the contact surface between the spring and the groove, especially on the contact area of the spring crest.
Bolt thread lubrication: Use specialized thread lubricants or anti-clogging agents with stable torque coefficients to ensure accurate control of preload. Avoid using regular engine oil or grease due to their unstable torque coefficients.
Cleaning is not only about removing dirt, but also about setting up proper conditions for lubrication and inspection.
Conventional oil contamination cleaning: Use environmentally friendly hydrocarbon cleaning agents or alkaline cleaning agents
Heavy oil contamination or carbon deposition: Ultrasonic cleaning combined with specialized cleaning solution
Special pollutant treatment:
Rust marks: Use a weakly acidic rust remover, then neutralize and dry immediately after treatment.
Polymer residue: Use the corresponding solvent-based cleaning agent
Contraindications: Avoid use of strong acids, strong alkalis, or cleaning agents that are corrosive to the spring substrate.
Clean immediately after disassembly: to prevent solidification of contaminants or corrosion
Graded cleaning policy:
Level 1: Removal of loose surface contaminants
Level 2: Deep cleaning of contact surfaces and crevices
Drying control: Use compressed air drying or low-temperature drying (≤80°C) to ensure complete drying and prevent flash rust.
Establish a performance verification system after lubrication cleaning:
1. Friction coefficient monitoring: Indirect evaluation is achieved by comparing equipment operating parameters (e.g., clutch engagement time, valve operating torque) before and after maintenance.
2. Temperature Monitoring: Install temperature sensors at critical application points to monitor lubrication performance
3. Regular Oil Sample Analysis: Oil Contamination Detection of Circulating Lubrication System
