Automation coupling: the precise “nerve endings” of intelligent manufacturing——The core link that drives high-precision motion control
In the wave of Industry 4.0 and intelligent manufacturing, automation couplings have surpassed the role of traditional mechanical connectors and become the “intelligent joints” of precision transmission systems.
It directly determines the motion stability, response speed and life of high-precision equipment such as robots, CNC machine tools, and semiconductor equipment, and is an indispensable technical cornerstone in the field of automation.
The ultimate demand for couplings in automation scenarios
Zero backlash transmission
Industrial robot joints, precision turntables and other scenarios require motion without lag, and couplings need to eliminate reverse clearance (such as diaphragm and bellows couplings with backlash ≤ 0.01°).
Application example: SCARA robot wrist joints use bellows couplings to ensure repeated positioning accuracy of ±0.02mm.
High-speed dynamic response
High-speed pick-and-place robots (beat> 200 times/minute) require couplings with low inertia and high rigidity (torsional stiffness> 10⁵ N·m/rad) to avoid resonance.
Technical solution: carbon fiber composite coupling (inertia reduced by 40%), titanium alloy lightweight design.
Compact space adaptability
Collaborative robot joints and AGV drive units require ultra-thin design (thickness <15mm), such as disc couplings (KTR’s Nabenflex series).
Extreme environment reliability
Semiconductor clean rooms (Class 10) and food and medicine sterile environments require no grease volatilization and corrosion resistance (fully sealed stainless steel or ceramic coating).
