Modern High-Frequency, Zero-Backlash Intermittent Motion Solutions

TECHNICAL EXCELLENCE

1. Mechanical Kinematics: Pure Rolling Friction & Zero Backlash

• Mechanism Logic: The globoidal cam on the input shaft meshes seamlessly with the tapered roller bearings on the output turret. Through the physical pre-loading of the cam and rollers, mechanical dead zones and backlash are eliminated at the source, ensuring absolute locking during both acceleration and dwell phases.

• Wear Resistance: Traditional sliding friction is entirely replaced by pure rolling contact. Even after millions of high-frequency cycles, the unit maintains arc-second indexing accuracy without precision degradation.

2. Dynamics Control: Mathematically Optimized Motion Curves

• Vibration Suppression: Standard configurations support multiple advanced acceleration curves—including Modified Sine (MS), Modified Trapezoid (MT), and Modified Constant Velocity (MCV50).

• Core Benefit: These mathematical profiles effectively smooth out peak acceleration, drastically reducing inertial shock and vibration during high-speed indexing, directly protecting upstream assembly mechanisms, robotic manipulators, and delicate workpieces.

3. Industrial Rigidity: Heavy-Duty Cast Housing & Lifetime Lubrication

• Structural Stiffness: The entire system is enclosed in a high-strength, multi-face precision-machined cast iron housing. It supports highly flexible mounting configurations across multiple faces (V, W, P, S, T, U) to integrate seamlessly into any machine frame layout.

• Maintenance-Free Design: Core internal transmission components run in a continuous oil bath for optimal heat dissipation and lubrication, minimizing downtime in 24/7 high-intensity production environments.

APPLICATION & PROBLEM SOLVING

Cam Indexing Systems

01 Main Application Fields

• Lithium-ion & New Energy Manufacturing: Multi-station rotary cell assembly lines, high-speed electrolyte injection machines, tab welding machines, and winding machines.

• 3C Electronics & Semiconductor Packaging: Chip mounter dial plates, mobile phone component assembly lines, high-speed LED sorting, and inspection equipment.

• Food, Daily Chemical & Pharmaceutical Packaging: Multi-head rotary filling machines, high-speed capping machines, labeling machines, and automated cartoning machinery.

• Automotive Component Automation: Multi-station automated welding, screw-driving, assembly, and inspection lines for headlights, clutches, and precision valve bodies.

02 Core Engineering Pain Points Solved

• Eliminating Backlash and Cumulative Error: Traditional "servo motor + standard reducer" setups introduce mechanical dead zones during frequent start-stop cycles, leading to cumulative positioning errors over time. The HG Cam Indexing System relies on mechanical rigid locking and pure rolling friction to physically eliminate backlash, ensuring long-term, absolute repeatability.

• Mitigating High-Speed Start-Stop Shock and Vibration: Under tight cycle times (e.g., indexing times below 0.5 seconds), instantaneous acceleration generates severe vibration. Our mathematically optimized motion curves (MS/MT) smooth peak acceleration from the source, preventing workpiece displacement and protecting upstream manipulators from damage.

• Resolving Cable Entanglement and Space Constraints: Multi-station pneumatic or electric fixtures frequently cause tangled lines during rotation. By offering stationary hollow centers (DT/DA series) and flat, ultra-thin profiles (PU series), engineers can route pneumatic lines and cables directly through the axis center or achieve stable heavy-duty transport within tight vertical clearance.
