Power Loss in Thrust Bearings :
Power Loss in Thrust Bearing :
- Bearings that give radial positioning to the rotor are known as line bearings, and those that locate the rotor axially are called thrust bearings.
- In most applications, the thrust bearings actually serve both as thrust and radial bearings.
- The main two purposes of the thrust bearing are, To keep the rotor in an exact position in the casing. To absorb axial thrust on the rotor due to steam flow.
- If a pump is operating too far on the left or right of its curve, the viscosity of the fluid is higher than expected, or there are large amounts of solids in the pumped fluid this can cause bearing overloading.
- This can lead to excess friction, overheating and prompt failure.
- Bearings reduce friction by providing smooth balls or rollers, and smooth inner and outer surfaces for the balls to roll against.
- These balls or rollers “bear” the load, allowing the device to spin smoothly.
- Then, the Balls, cylindrical rollers, tapered rollers, spherical rollers and needle rollers are the most common rolling elements used for thrust applications.
Uses :
- Thrust bearings are commonly used in automotive, marine, and aerospace applications.
- They are also used in the main and tail rotor blade grips of RC (radio controlled) helicopters.
Formula :
- The formula for the calculation is given below.
- Power Loss in Thrust Bearings = (0.0000007 * Rotational Speed * Total Thrust).
- Beside the formula this calculator works.
How to Calculate ?
- First, Enter the Rotational Speed. Then,
- Second, Enter the Total Thrust. Then,
- Click “Calculate” to get the result and then if you want to clear values Click “Reset” in addition to clear the values.
- Finally, follow these steps to get the result.
