JOURNAL BEARING APPARATUS

Product Description

The apparatus consists of a plainsteel shaft excavated in a bearing and directly driven by a FHP Motor.

The bearing is freely supportedon the shaft and sealed at the motor end. The speed of the motor is controlledaccurately by the speed control unit and it can be made run in both directions.

Twelve equal-spaced pressuretaping around the circumference and four along the axis are provided and areconnected to manometer by PU Tubing so that the pressure head of oil in alltubes can be observed at a time.

The bearing can be loaded byattaching weights to the arm supported beneath it.

Experiments

To study the pressure profile oflubricating oil at various conditions of load and speed

Plotting the Cartesian polarpressure curves

To measure the frictional torqueand power transmit

Utilities Required

Electric supply: 230 V AC, SinglePhase.

Bench area: 1.5 x 1.5 x 4 m

Tachometer to find out RPM ofjournal

Oil SAE 40 about 5 Ltrs.
