The GUNT Journal Bearing with Hydrodynamic Lubrication Trainer allows the study of hydrodynamically lubricated radial journal bearings, where a lubricating film separates the shaft and bearing shell during operation. The unit features five shafts with different diameters to analyze operating behaviour as a function of bearing clearance.
Product Features
- Hydrodynamic lubrication creates a supporting film separating shaft and bearing shell during operation.
- Pressure in the lubricating film is generated by relative motion between shaft and bearing shell.
- Position of the shaft related to speed and load is crucial for tribological analysis.
- Five shafts with different diameters allow study of bearing clearance effects on performance.
- Radial load applied manually via handwheel and measured electronically.
- Frictional moment measured using a force sensor.
- Shaft driven by three-phase motor with continuously adjustable speed via frequency converter; speed displayed digitally.
- Oil temperature controlled and adjusted using a controller.
- Inductive sensors detect shaft motion in the bearing, measuring position at four points in X and Y directions.
- Oil temperature, pressure, and peak pressure in the bearing measured and displayed via sensors.
- Measured values can be transmitted via USB to a PC for analysis with included software.
Benefits
- Allows comprehensive study of hydrodynamic lubrication and bearing clearance effects.
- Enables real-time measurement and visualization of shaft position and frictional forces.
- Adjustable load and speed enable diverse experimental conditions.
- Digital data acquisition and PC interface facilitate detailed analysis and documentation.
- Ideal for education and research in tribology, mechanical engineering, and bearing design.
