Rubber Rolling Resistance Tester: Precision Measurement for Rubber Material Performance
The Rubber Rolling Resistance Tester is engineered to evaluate the rolling resistance of rubber materials by simulating real-world motion conditions. Its core testing principle involves subjecting a circular wheel-shaped rubber specimen (active wheel) to controlled relative motion against a passive metal wheel drum, all under a specified load and constant speed. The tester employs a torque measurement method: the rubber wheel functions as the driving component, while the metal wheel acts as the passive resistance element. By measuring the driving torque of the active wheel and applying a preset load to the passive wheel, the system accurately calculates rolling resistance—critical data for assessing material efficiency and durability.
- Outer Diameter: 102mm
- Inner Diameter: 63.5mm
- Width: 19mm
- Speed Range: 400–120rpm (stepless adjustment)
- Drive Motor: High-performance servo motor
- Torque Measurement Range: 0–50N·m
The active rubber wheel is precision-engineered to replicate the dimensions of real-world components (e.g., tire treads), ensuring test results correlate with actual performance. The stepless speed adjustment (120–400rpm) allows simulation of varying motion velocities, from slow-moving industrial equipment to high-speed vehicle conditions. The servo motor delivers stable, consistent rotation, minimizing speed fluctuations that could skew torque measurements, while the 0–50N·m torque range accommodates testing of both soft and rigid rubber compounds.
- Outer Diameter: 102mm
- Width: 20–25mm
Designed to match the active wheel’s diameter, the passive metal wheel provides uniform contact with the rubber specimen, ensuring consistent friction distribution during testing. Its adjustable width (20–25mm) allows compatibility with different rubber wheel sizes, enhancing the tester’s versatility for diverse material samples.
- Configuration: PLC (Programmable Logic Controller) + HMI (Human-Machine Interface) touchscreen
The integrated PLC and HMI touchscreen deliver intuitive, precise control over all test parameters. Operators can easily set load values, speed, and test duration via the full-color interface, which also displays real-time data (torque, resistance force, friction coefficient) and test progress. This automation reduces human error and streamlines workflows, making the tester accessible to both experienced technicians and new users.
- Composition: Heavy-duty transmission mechanism + high-precision imported sensors
- Load Range: 10–80kg (maximum 100kg)
- Loading Method: Programmable software control with customizable settings
The loading system applies consistent, adjustable pressure to the passive wheel, simulating varying weight conditions (e.g., light vs. heavy vehicle loads). High-precision imported sensors ensure load accuracy, with minimal drift even during extended tests. The programmable software allows users to create custom loading profiles—such as gradual load increases or constant load application—mimicking real-world stress scenarios for more accurate material evaluation.
- Torque (of the active wheel)
- Resistance force
- Friction coefficient
These metrics provide a comprehensive analysis of rolling resistance: torque measures the force required to drive the rubber wheel, resistance force quantifies the opposing friction, and the friction coefficient offers a standardized ratio for comparing materials across tests.
- Dimensions: 800×600×400mm (W×D×H)
- Power Supply: 220V, 3KW
With a compact footprint (800×600×400mm), the tester fits easily into laboratory or production floor environments. The 220V, 3KW power supply ensures compatibility with standard industrial electrical systems, eliminating the need for specialized wiring.
The Rubber Rolling Resistance Tester is indispensable across industries reliant on rubber components:
- Automotive & Tire Manufacturing: Evaluating tire tread compounds to optimize fuel efficiency (lower rolling resistance reduces energy consumption).
- Industrial Equipment: Testing rubber wheels for conveyor systems, forklifts, and machinery, ensuring durability under heavy loads.
- Aerospace: Assessing rubber components in landing gear and cargo systems, where resistance efficiency impacts operational performance.
- Material Science Research: Developing new rubber blends with balanced friction and wear properties for specialized applications.
Combining precision engineering with user-centric design, the Rubber Rolling Resistance Tester delivers accurate, repeatable data for critical material evaluations. Its ability to simulate real-world conditions—via adjustable speed, load, and torque measurement—makes it a vital tool for quality control, research and development, and compliance testing. Whether for optimizing tire efficiency or enhancing industrial rubber components, this tester provides the insights needed to drive innovation and ensure material performance.
