The GUNT Friction in Journal Bearings Experimental Unit enables study of the factors influencing friction in hydrodynamic journal bearings, focusing on speed, load, and lubricant viscosity. It features an electrically driven shaft journal rotating in a freely movable bearing housing, allowing observation of oil movement within the bearing.
Product Features
- Studies factors affecting friction in hydrodynamic journal bearings such as speed, load, and lubricant viscosity.
- Electrically driven shaft journal rotates within a freely movable bearing housing.
- Applied load transmitted to bearing housing via load application device with adjustable weights.
- Frictional moment measured by a movable weight balancing a balance beam moment.
- Shaft journal driven by an electric motor with speed control via frequency converter.
- Temperature sensor in bearing shell records lubricant temperature, displayed on control unit screen.
- Lubricant supplied through wick oiler applying oil via two grooves in the bearing bush.
- Leakage oil collected in a dedicated collecting tank for cleanliness and analysis.
Benefits
- Allows detailed investigation of friction behaviour under varying operational conditions.
- Adjustable speed and load enhance experimental flexibility.
- Temperature and viscosity monitoring supports comprehensive lubrication analysis.
- Visual observation of lubricant movement aids understanding of hydrodynamic lubrication principles.
- Clean design with oil collection maintains lab hygiene and safety.
