How to use "tabela de torque de parafusos"
A "tabela de torque de parafusos" (bolt torque table) is a crucial tool for ensuring that bolts are tightened correctly, which is essential for safety and performance in mechanical and structural applications. Here's how to use it:
1. **Identify Bolt Specifications**: Determine the specifications of the bolt you are using, including its diameter, grade, and thread pitch. These details are usually found on the bolt itself or in the technical documentation.
2. **Consult the Table**: Look up the appropriate torque value in the torque table. The table will typically list bolts by diameter and grade, providing the recommended torque in Newton-meters (Nm) or foot-pounds (ft-lbs).
3. **Match Bolt and Table Values**: Ensure that the bolt's specifications match the corresponding row in the table. For example, if you have a Grade 8 bolt with a 10mm diameter, find the torque value listed for that specific grade and size.
4. **Use Proper Tools**: Use a calibrated torque wrench to apply the specified torque. A torque wrench allows for precise application of force, which is critical for achieving the correct tightness without over-tightening or under-tightening.
5. **Apply Torque Gradually**: When tightening bolts, do so gradually and in a crisscross pattern if there are multiple bolts. This ensures even distribution of pressure and prevents misalignment.
6. **Verify Torque**: After applying the initial torque, re-check each bolt to ensure they are all torqued to the specified value. Some applications may require a secondary check after initial use to account for settling or stretching.
**Example:**
If you have an M8 bolt with a 1.25mm pitch made from steel with a Grade 10.9 rating, you would:
1. Identify the bolt as M8 x 1.25, Grade 10.9.
2. Locate this specification in the torque table.
3. Find the recommended torque value, say 36 Nm.
4. Use a torque wrench to tighten the bolt to exactly 36 Nm.
By following these steps, you can ensure that bolts are correctly and safely torqued, preventing failures and maintaining the integrity of the assembly.
"tabela de torque de parafusos" Comparative Analysis
A “tabela de torque de parafusos” (bolt torque table) provides essential guidelines on the appropriate torque values for tightening bolts of different sizes and materials. Here’s a comparative analysis of common bolt torque tables:
### Material Differences
1. **Steel vs. Stainless Steel**:
- **Steel bolts** generally have higher torque values compared to stainless steel bolts. This is due to the higher strength and lower friction coefficient of steel.
- **Stainless steel** bolts, while resistant to corrosion, tend to have lower torque values to prevent galling and thread damage.
2. **Aluminum Bolts**:
- These have the lowest torque values because aluminum is softer. Excessive torque can easily damage the threads or distort the bolt.
### Bolt Grades
1. **Grade 2, 5, 8** (common in the U.S.):
- **Grade 2**: Lowest strength, suitable for light-duty applications.
- **Grade 5**: Medium strength, standard for automotive applications.
- **Grade 8**: High strength, used in high-stress and critical applications.
2. **Metric Classes (8.8, 10.9, 12.9)**:
- **Class 8.8**: Equivalent to Grade 5, common in construction.
- **Class 10.9**: Higher strength, similar to Grade 8.
- **Class 12.9**: The strongest, used in heavy machinery and critical components.
### Size and Thread Pitch
1. **Bolt Diameter**:
- Larger diameter bolts require higher torque values to achieve the same clamping force as smaller ones.
- Example: M6 bolts typically require less torque than M10 bolts.
2. **Thread Pitch**:
- Fine threads (closer pitch) need less torque compared to coarse threads (wider pitch) for the same diameter, due to lower friction and better load distribution.
### Application of Lubrication
- **Lubricated Bolts**: Torque values are generally lower because lubrication reduces friction, allowing for more efficient clamping force.
- **Dry Bolts**: Higher torque values are needed to overcome the friction between threads.
### Safety Factors
- **Over-torquing**: Risks breaking the bolt or damaging the component.
- **Under-torquing**: Can lead to loosening and failure under load.
### Practical Use
- Always refer to manufacturer specifications for precise torque values, considering material, grade, and size.
- Utilize a calibrated torque wrench to ensure accuracy.
In summary, bolt torque tables vary based on material, grade, size, thread pitch, and lubrication. Selecting the correct torque value is crucial for ensuring joint integrity and safety.
