DAOLER® Friction Shims: An Essential Component for Enhancing Robotic Performance – Building Better Robots.
In the field of robotics, where ultimate precision, speed, and reliability are paramount, every single interface—no matter how small—can become the decisive factor that defines the upper limit of performance. From high-speed rotating joints to end-effectors executing precise tasks, conventional bolted connections, under prolonged high-load operation, are prone to microscopic slip and loosening. This inevitably leads to accuracy degradation, reduced service life, and even mission failure. Today, a game-changing solution—the DAOLER® Diamond Friction Shim—is emerging as an indispensable enabler for building superior robots.
Why Do Robotic Connections Need a "Game-Changer"?
The core value of a robot lies in its repeatable accuracy, reliable stiffness, and rapid-response agility. However, all of these attributes rest upon the absolute integrity of every joint and link connection. Conventional fastening technologies face the following challenges:
Loss of Precision: Under cyclic loading, micron-level relative motion at the interface accumulates into significant positioning errors over time.
Insufficient Stiffness: Even minute "play" at the joint reduces system rigidity, induces vibration, and compromises machining quality or operational stability.
Trade-off Between Size and Weight: Achieving high stiffness often requires oversized fasteners and larger joint geometries, which directly contradicts the industry's push toward lightweight, compact robot designs.
DAOLER® Friction Shims: Redefining Joint Rigidity
The DAOLER® Diamond Friction Shim fundamentally addresses these issues through an innovative "micro-embossing" technology.
1. Ultimate Precision – Reinforcing Core Joints
Engineered specifically for precision applications, the DAOLER® Friction Shim operates within extremely tight engineering tolerances. It is installed between bolted mating surfaces at critical locations—such as robot wrists, end-effectors, joints, links, and grippers. Under bolt preload, the partially embedded ultra-hard diamond particles aggressively "bite" into the opposing surfaces, creating a powerful mechanical interlock.
Effect: This mechanism elevates the static friction coefficient by a factor of 3 to 5, virtually eliminating microscopic interfacial slip. The result is a dramatic enhancement in joint stiffness, yielding crisper, more decisive motion. Even under high-speed movement and heavy payloads, absolute posture stability is maintained, ensuring the highest levels of operational accuracy.
2. Enabling Miniaturized Design – Unlocking Lightweight Potential
By reinforcing joints with DAOLER® Friction Shims, designers can achieve equivalent or even superior connection rigidity compared to conventional solutions, while simultaneously allowing the use of smaller, lighter bolts and fasteners.
Effect: This permits a reduction in component contact areas and overall assembly dimensions. More compact joint designs enable robots to navigate tightly constrained automation cells with ease, while also delivering significant weight savings for the robot itself.
3. Reducing Inertia – Enhancing Dynamic Performance
The decrease in component size and weight directly translates into a substantial reduction in moving inertia—a critical lever for improving robotic dynamic performance.
Effect: Lower inertia allows for faster starts, stops, and reversals, substantially reducing cycle times and boosting productivity. Moreover, motion requires less driving force, leading to lower energy consumption and reduced impact on motors and gearboxes, thereby extending the service life of core components. This greatly facilitates rapid, flexible, and accurate operation of robotic equipment within confined spaces.
Application Examples:
Collaborative Robot Joints: Integration of DAOLER® Shims enables slimmer arm designs without compromising safety or accuracy, enhancing the flexibility and safety of human-robot collaboration.
Industrial Robot Wrists: In high-frequency, heavy-load handling or machining operations, the shims prevent joint loosening, ensuring long-term repeatable positioning accuracy of the Tool Center Point (TCP).
Precision Assembly Grippers: Enhanced joint rigidity suppresses micro-vibrations, guaranteeing accurate positioning of delicate components during high-speed assembly processes.
Conclusion
In today's rapidly advancing robotics landscape, the DAOLER® Diamond Friction Shim has transcended its role as a mere component. It stands as a key enabling technology for achieving next-generation robotics—characterized by superior performance, higher efficiency, and uncompromising reliability. By reinforcing connections at the most fundamental level, it endows robots with stronger "musculoskeletal" integrity. It is an indispensable element in the design of tomorrow's smaller, lighter, faster, and more precise robots.
