Washers are thin plate-like mechanical components with a central hole, typically used to distribute the load of threaded fasteners, prevent loosening, or create seals. As critical elements in assembly systems, they enhance structural integrity, reduce wear, and improve vibration resistance. Modern engineering applications rely on washers to optimize performance across diverse environments.
| Type | Functional Characteristics | Application Examples |
|---|---|---|
| Flat Washers | Distribute load, prevent surface damage | Machinery bases, construction equipment |
| Spring Washers | Provide axial tension, absorb vibrations | Automotive engines, railway tracks |
| Lock Washers | Prevent nut/bolt rotation under vibration | Aerospace fasteners, industrial pumps |
| Sealing Washers | Create fluid/gas-tight barriers | Pipe flanges, hydraulic systems |
Typical washers feature a flat annular design with precise inner/outer diameter ratios. Advanced variants incorporate:
| Parameter | Importance |
|---|---|
| Material Hardness (HV/HRC) | Determines wear resistance and load capacity |
| Inner Diameter Tolerance ( m) | Affects fit precision with fasteners |
| Corrosion Resistance (hrs in salt spray) | Dictates service life in harsh environments |
| Spring Rate (N/mm) | Measures elasticity for vibration damping |
| Operating Temperature Range ( C) | Defines thermal stability limits |
| Manufacturer | Representative Product | Key Feature |
|---|---|---|
| Nord-Lock Group | X-series washers | wedge-locking system for vibration resistance |
| ITW Shakeproof | Prevailing torque washers | Deformable split ring design |
| MISUMI | FCMZ series spring washers | Optimized for robotic assembly |
Key considerations include:
Example: Selecting stainless steel Belleville washers for offshore wind turbine bolts ensures corrosion resistance and maintains clamping force under dynamic loads.
