In industrial equipment, lock bolts & collars are small components that directly affect the reliability, accuracy, and longevity of the equipment.
In recent years, with the advancement of materials science and manufacturing technology, the structural optimization of basic fasteners
is bringing breakthrough application possibilities to emerging fields.
Traditional applications and challenges
- Material limitations: Although traditional materials such as high-strength steel and titanium alloys can meet basic needs, their performance may decline in extreme environments (such as high temperatures, corrosion).
- Single structural design: Traditional locking bolts rely on fixed geometry and are difficult to adapt to diverse assembly needs.
- Inefficient installation: Some locking bolts require special tools to install, which increases the complexity of operation.
Three directions of structural optimization
1. Material upgrades
- High-strength alloy steel, titanium alloy or composite materials are used to improve tensile strength and corrosion resistance.
- For example, DLC (diamond-like carbon) coating reduces the coefficient of friction by 50% and is suitable for high-precision robot joints.
2. Geometric design innovation
- Finite element analysis optimizes contact surface shape to reduce stress concentration.
- Asymmetrical locking tooth design improves loosening resistance under dynamic loads.
3. Surface treatment technology
- Laser micro-fabrication or ion implantation technology enhances wear resistance.
- In harsh environments such as wind power and mining machinery, the service life can be increased by 2-3 times.
New application scenarios have been spawned
- Humanoid robot: Zero-backlash locking structure ensures precision in joint movement.
- Floating offshore wind power: Anti-vibration loosening design adapts to dynamic marine environments.
- Semiconductor equipment: ultra-high cleanliness materials meet the requirements of pollution-free.
Structural optimization of tightening bolts and bushings is not only an inevitable choice for performance improvement, but also a catalyst for cross-industry innovation. Small locking bolts and bushings are opening up even greater possibilities for industrial equipment through continuous optimization.
