SV904 – Bearing Friction Apparatus
Allows students to compare the frictional losses of bearings by measuring the coefficient of sliding friction between pairs of materials
Description
The apparatus consists of a flywheel on a horizontal shaft carried in a pair of similar bearings, the flywheel being used to even out small variations in friction.
The shaft is of mild steel, and interchangeable bearings in a range of materials are provided. This experiment provides an opportunity to study journal bearing friction over a range of commonly used materials including a self lubricating sintered bronze.
For comparison a ball bearing is supplied to demonstrate the advantages of rolling rather than sliding contact. Torque is applied by a loaded cord wrapped round the flywheel shaft.
A set of calibrated weights and load hanger is supplied for loading the flywheel.
Technical Specifications
- Ships complete with four bearing types – cast iron, Tufnel, sintered bronze, ball bearing
- Load hanger applies torque to flywheel
- Calibrated weights set supplied: 1 x 0.5N, 1 x 1N, 2 x 2N, 1 x 5N, 2 x 10N
- Disk size approximately Ø300mm x 40mm (W). Can double as flywheel apparatus if required
Features & Benefits
- The wall mounted unit consists of a flywheel Ø300mm x 40mm (W) (approx.) on a horizontal steel shaft. Interchangeable bearing materials house the shaft
- Bearings are cast iron, Tufnol, sintered bronze and ball bearings
- Torque is provided by a load hanger and loaded cord wrapped around the flywheel shaft
- Can be mounted to the SV100 Bench Mounted Frame
- Allows students to compare the frictional losses of bearings by measuring the coefficient of sliding friction between pairs of materials
- Allows students to measure the compare and contrast losses when comparing different bearing types
