Neometrix Gear Box Test Bench

Product Overview
The Neometrix Gear Box Test Bench is a purpose-built, skid-mounted rig designed to evaluate and validate gearbox performance across a variety of load, speed, and gear-combination scenarios. Tailored for Escorts Agrimachinery’s PU-Transmission Division, it precisely measures input versus output RPM, torque, and optional PTO shaft speeds on centre-shift, side-shift, 9+3-speed, and DC/TRB gearboxes. Its modular design ensures compatibility across Escort’s full gearbox lineup while simplifying installation and maintenance.

System Architecture
- Hydraulic Power Packs (HPPs): Two independent units deliver clean, filtered fluid (10 µm suction, 25 µm return) for gearbox actuation and optional anti-rust spray operations. Rated to 250 bar with auto-switching relief and unloading valves.
- Mechanical Fixture & Structure: A robust fabricated steel frame houses the gearbox mounting fixture with pneumatic clamps, tilting assembly for oil drainage, and integrated drip tray. Quick-release spline adaptors ensure precise alignment.
- Drive & Measurement: A 20 HP VFD-controlled motor (ABB/Siemens) drives the gearbox via spline adaptors. High-precision torque sensors (Lorenz Mestechnik) and RPM/proximity sensors (Omron) capture real-time data.
- Control & DAQ: PC-based National Instruments system (or Siemens PLC/HMI alternative) orchestrates test sequences, logs timestamped data, and generates customizable PDF/Excel reports.

Technical Specifications
- Test Capacity: Five selectable speed profiles (I–IV forward, reverse, high/low gears)
- Pressure Rating: Hydraulic system up to 250 bar
- Filtration: 10 µm suction, 25 µm return for extended component life
- Data Logging: Records operator ID, shift, gearbox serial, gear combination, RPM/torque readings, and OK/NG verdict
- Construction: Skid-mounted steel frame with epoxy powder coat; integrated drip tray and drain pipe

Control & Software
- Custom Test Profiles: Define duration and speed per gear with overshoot allowances
- Real-Time Monitoring: Dashboards display torque, RPM, and hydraulic parameters; alarms and indicators for anomalies
- Automated Reporting: Generates PDF/Excel reports, customizable to client requirements

Operation & Workflow
1. Setup: Mount gearbox on fixture, engage pneumatic clamps, align spline adaptors.  
2. Engagement: Close housing via inch switches; sensors verify pin engagement.  
3. Testing: Fill oil, then run the selected test sequence automatically through predefined gear steps.  
4. Drain & Unload: Tilt housing for oil drainage; release clamps and remove gearbox for marking or further processing.

Applications
- Production Quality Assurance: End-of-line testing of agricultural and automotive gearboxes to verify torque, speed ratios, and sealing integrity. Batch validation of 9+3-speed and DC/TRB units.
- Research & Development: Characterize noise, vibration, and fatigue life of prototype gearboxes; compare materials and coatings under accelerated cycles.
- Failure Analysis & Troubleshooting: Replicate fault conditions for root-cause analysis of wear patterns and validate corrective measures via controlled overload and reverse-torque tests.
- Aftermarket & Refurbishment: Validate remanufactured gearboxes to ensure performance metrics match or exceed OEM standards; certify rebuilt units for warranty and regulatory compliance.
- Training & Educational Labs: Provide hands-on modules for vocational institutes and OEM service centers on assembly alignment, hydraulic actuation, and data-driven diagnostics.
- Specialized Industrial Equipment: Test PTO gearboxes for agricultural machinery under fluctuating loads; validate gearboxes in construction, mining, and material-handling systems subject to high-shock and cyclic loading.

Safety & Standards
Certifications: Built in an ISO 9001:2008 facility with OEM-calibrated sensors, poka-yoke interlocks, and emergency stops.  
Environmental Compliance: Utilizes non-hazardous materials where possible; complete handling and disposal guidelines provided.

Advanced Features
- Enhanced Diagnostics & Condition Monitoring: Embeds multi-sensor arrays (vibration, temperature, oil-condition, and acoustic) for continuous condition monitoring, coupled with machine-learning for predictive maintenance.
- Industry 4.0 Connectivity & Digital Twin Integration: Utilizes IIoT protocols (OPC-UA, MQTT) and cloud platforms to feed real-time test data into a digital twin for remote supervision and collaborative R&D.
- Modular Expandability & Environmental Simulation: Supports plug-and-play modules—such as climatic chambers (–40 °C to +180 °C), humidity control, and battery simulators—to replicate extreme conditions.
- Energy Efficiency & Regenerative Drive Options: Integrates regenerative drive systems capturing braking energy for up to 75% recovery, reducing power consumption and operational costs.

Conclusion
By combining robust hydraulics, precise instrumentation, and versatile control systems with predictive analytics, IIoT-enabled digital twins, modular environmental simulation, and regenerative energy recovery, the Neometrix Gear Box Test Bench transcends traditional rigs. It delivers deeper insights, optimizes energy usage, and dynamically adapts to evolving drivetrain technologies—making it the premier choice for quality assurance, R&D, maintenance, and lifecycle management of gearbox systems.
