JOURNAL BEARING APPARATUS

About JOURNAL BEARING APPARATUS

Specification:

JOURNAL BEARING APPARATUS

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

The bearing is freely supported onthe 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 pressure tapingaround the circumference and four along the axis are provided and are connectedto manometer by PU Tubing so that the pressure head of oil in all tubes can beobserved 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 polar pressurecurves

To measure the frictional torque andpower transmit

Utilities Required

Electric supply: 230 V AC, Single Phase.

Bench area: 1.5 x 1.5 x 4 m

Tachometer to find out RPM of journal

Oil SAE 40 about 5 Ltrs.
