The GUNT Pressure Distribution in Journal Bearings Experimental Unit visualizes the pressure curve within a journal bearing under hydrodynamic lubrication. The unit features multiple measuring points around the bearing shell and along its length, allowing precise pressure readings via a 16-tube manometer. An electrically driven shaft journal rotates within a freely movable bearing housing lubricated with oil.
Product Features
- In hydrodynamic journal bearings, the shaft and bearing shell are separated by a lubricating film during operation, supporting the shaft via pressure distribution in the bearing gap.
- The unit visualizes the pressure curve with twelve measuring points around the bearing circumference and four along the length.
- Pressure is read via a 16-tube manometer referencing the height of the liquid columns.
- The journal bearing consists of an electrically driven shaft journal rotating in a freely movable bearing housing.
- Oil is used as the lubricant to simulate real operating conditions.
- Shaft journal displacement depends on speed, direction of rotation, and start-up behaviour, visible through a transparent bearing housing.
- Speed and direction of rotation are adjustable to demonstrate different operating states.
- Load on the journal bearing is adjustable by varying weights applied to the shaft.
- Temperature in the bearing gap is measured to determine lubricant viscosity.
Benefits
- Provides hands-on visualization of pressure distribution in hydrodynamic journal bearings.
- Enables study of lubrication film behaviour and bearing load under varying conditions.
- Adjustable speed, direction, and load support diverse experimental setups.
- Transparent housing allows direct observation of shaft displacement and bearing behaviour.
- Temperature measurement supports analysis of lubricant viscosity changes during operation.
