Product Description

Product Description

A wavy spring washer is a type of spring washer designed to provide a flexible, load-bearing cushion between two surfaces. It is characterized by its wavy or undulating shape, which allows it to compress and absorb shock, vibration, or thermal expansion in mechanical assemblies. Wavy spring washers are commonly used to maintain tension, reduce loosening, and compensate for wear in bolted joints or other applications.

Key Features of Wavy Spring Washers

1. Wavy Design:

   • The washer has multiple waves or curves around its circumference, giving it a spring-like property.

   • The waves allow the washer to compress and expand, providing consistent pressure.

2. Material:

   • Typically made from spring steel, stainless steel, or other high-strength materials.

   • Materials are chosen based on the application's requirements for strength, corrosion resistance, and temperature tolerance.

3. Load Distribution:

   • Distributes load evenly across the surface, reducing stress on the bolted joint or assembly.

4. Compensates for Movement:

   • Absorbs vibration, shock, and thermal expansion/contraction, preventing loosening of fasteners.

• Vibration Resistance: Prevents loosening of fasteners in high-vibration environments.

• Thermal Compensation: Accommodates expansion and contraction due to temperature changes.

• Load Distribution: Reduces stress on joints and surfaces.

• Cost-Effective: Simple design and low cost make them a practical solution for many applications.

• Easy to Install: Lightweight and easy to integrate into assemblies.

Packaging & Shipping

 

Proper packing of wave springs is essential to prevent damage during storage, handling, and transportation. Here are the **key steps and considerations** for packing wave springs properly in spring production:

---

### **1. **Individual Protection**
   - **Anti-Corrosion Packaging**: Use anti-rust paper, VCI (Vapor Corrosion Inhibitor) paper, or plastic bags to wrap each spring, especially if they are made of materials prone to corrosion (e.g., carbon steel).
   - **Foam or Bubble Wrap**: For delicate or precision wave springs, wrap each spring in foam or bubble wrap to prevent scratches and dents.

---

### **2. **Grouping and Sorting**
   - **Batch Packing**: Group springs of the same size, type, and specification together to avoid mixing.
   - **Labeling**: Clearly label each batch with details such as part number, material, dimensions, and quantity.

---

### **3. **Container Selection**
   - **Plastic Trays or Dividers**: Use plastic trays with individual compartments to hold each spring securely and prevent movement during transit.
   - **Cardboard Boxes**: For larger quantities, use sturdy cardboard boxes with dividers or inserts to keep springs separated and protected.
   - **Reusable Containers**: For industrial customers, consider reusable plastic or metal containers for eco-friendly and cost-effective shipping.

---

### **4. **Cushioning and Filling**
   - **Padding Material**: Fill empty spaces in the box with cushioning materials like foam, bubble wrap, or packing peanuts to prevent springs from shifting.
   - **Layered Packing**: For multiple layers of springs, use separators (e.g., cardboard or foam sheets) between layers to avoid compression damage.

---

### **5. **Sealing and Securing**
   - **Seal Boxes Properly**: Use strong packing tape to seal boxes securely, ensuring they can withstand handling and transportation.
   - **Strapping**: For heavy or large shipments, use strapping to reinforce the boxes and prevent them from opening.

---

### **6. **Environmental Protection**
   - **Moisture Control**: Include desiccant packets in the packaging to absorb moisture and prevent rust, especially for long-term storage or humid environments.
   - **Temperature Considerations**: For sensitive materials, use insulated packaging if the springs will be exposed to extreme temperatures during transit.

---

### **7. **Labeling and Documentation**
   - **External Labels**: Clearly label the outside of the package with handling instructions (e.g., "Fragile," "Keep Dry") and destination details.
   - **Packing List**: Include a packing list inside the box detailing the contents, quantities, and part numbers for easy identification.

---

### **8. **Quality Check Before Shipping**
   - Inspect the packed springs to ensure they are secure and well-protected.
   - Verify that the packaging meets customer or industry-specific requirements.


 

The applications

 

How Wavy Spring Washers Work

• When a bolt or fastener is tightened, the wavy spring washer compresses, creating a spring force that maintains tension in the joint.

• The washer's waves allow it to flex and adapt to changes in the assembly, such as thermal expansion or vibration.

 

Applications of Wavy Spring Washers





**Applications of Wave Springs in Various Mechanisms**  

Wave springs are versatile components used in a wide range of applications due to their ability to provide precise force in compact spaces. Below are examples of how wave springs are utilized in different mechanisms:  



### **1. Pressure Relief Valve**  
A flat wire wave spring applies an exact load to the top sealing plate. When air pressure enters through the top slots, it forces the plate away from the sealing surface, enabling the pressure relief mechanism.  
-

### **2. Face Seal**  
Wave springs apply precise pressure to load a carbon face against a mating surface, ensuring a proper fluid seal. Unlike stamped wavy washers, wave springs maintain a consistent spring rate over a fixed working range.  



### **3. Clutch Drive**  
In clutch drives, a wave spring (Wavo Spring) is compressed between sheave halves to produce pressure on the round belt. The top threaded cap adjusts the compression, allowing the wave spring to generate high force in a tight radial space.  


### **4. Bayonet Connector**  
An overlap-type wave spring is installed in electronic connector assemblies. When male and female components are rotated into their final position, the wave spring compresses to its working height, exerting a constant force that locks the components together.  


### **5. Multi-Tooth Cutter**  
A custom-designed wave spring with locating tabs is housed within the cutter assembly. The spring applies precise force to the cutter halves, allowing them to oscillate without rattling.  



### **6. Slip Clutch**  
In slip clutches, a wave spring maintains pressure to hold "V"-detents in "V"-slots, enabling the clutch to drive. When torque increases, the detents ride out of the slots, compressing the wave spring and activating the slip mechanism. When torque decreases, the spring forces the detents back into the slots to resume driving.  

---

### **7. Bearing Pre-Load**  
Wave springs are widely used for bearing pre-load applications. Proper pre-loading extends bearing life by reducing operating temperatures, minimizing vibration, and ensuring smoother, quieter performance.  

---

### **8. Flow Valve**  
Crest-to-Crest wave springs control the linear displacement of a piston in flow valves. As fluid pressure increases, the spring adjusts the piston's position to regulate fluid flow. The compact design of the wave spring allows for smaller valve sizes.  

---

### **9. Low Voltage Connector**  
In low-voltage connectors, a 2-turn nested Spirawave wave spring provides pre-load between male and female components. This design delivers higher loads in tight radial and axial spaces.  

---

### **10. Pop-Up Flow Valve**  
A Crest-to-Crest wave spring maintains constant pressure on the pop-up head, keeping it firmly closed. Water pressure overcomes the spring's force to release the head during operation.  

---

### **11. Oil Valve**  
In oil valves, Crest-to-Crest wave springs provide precise resistance to regulate oil release. Their compact design allows for smaller valve sizes without compromising performance.  

---

### **12. Ball Valve**  
Crest-to-Crest wave springs reduce the overall spring height in ball valves, enabling the seat to oscillate on the ball for a tight seal. This design also reduces the valve's weight and size.  

---

### **13. Quick Disconnect**  
In quick-disconnect mechanisms, a Crest-to-Crest wave spring holds the sliding member in its locked position against a retaining ring. When the member is slid backward, the spring compresses, releasing the detent balls.  

---

### **14. Vibration Isolator**  
Wavo springs are used in vibration isolators to provide high force and large axial displacement in limited space. Arranged in series, they offer additional travel for effective vibration damping.  

---

### **15. Floating Gear**  
In floating gear assemblies, a Crest-to-Crest wave spring applies light force to a gear, allowing axial movement. This enables the gear to self-align with its mating gear during operation.
