Total Thrust Acting on Driver Thrust Bearing :
Definiton :
- 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.
- Axial bearings, or thrust bearings, are designed to withstand force in the same direction as the shaft.
- Then it is called an axial load, or thrust load.
- In some applications, ceramic bearings, a type of radial bearing, are used to withstand high rotational speeds.
- The axial thrust is the resultant force of all the axial forces (F) acting on the pump rotor.
- A force that is applied along a bearing’s axis.
Uses :
- Thrust bearings support the axial thrust of both horizontal and vertical shafts.
- Then, The functions are to prevent the shaft from drifting in the axial direction and to transfer thrust loads applied on the shaft.
- Balls, cylindrical rollers, tapered rollers, spherical rollers and needle rollers are the most common rolling elements used for thrust applications.
- To keep the rotor in an exact position in the casing.
- To absorb axial thrust on the rotor due to steam flow.
Formula :
- The formula for the calculation is given below.
- Total Thrust Acting on Driver Thrust Bearing = (Bowl Thrust Factor * Total Dynamic Head) + (Shaft Weight * Setting from Head Base to Top of Bowls).
- Beside the formula this calculator works.
How to Calculate ?
- First, Enter the Bowl Thrust Factor. Then,
- Second, Enter the Total Dynamic Head. Then,
- Third, Enter the Shaft Weight. Then,
- Fourth, Enter the Setting from Head Base to Top of Bowls. 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.
