M15.8 Bearing, Seals And Accesories Flashcards
Types of Bering systems
- Fixed
- Floating
Which bearing system supports the rotor in the radial direction and fixes the rotor in the axial direction
Fixed bearing
Which bearing system can only transmit radial forces because it can move axially
Floating
Which type of bearing can transmit axial and radial forces
Fixed bearing
What type of bearing system can minimise the expansion of the shaft end
Triple bearing system
Parts of a ball bearing
- Inner race
- Outer race
- Balls
- Cage
Ball bearings can transmit which loads
Axial and radial forces
What type of bearing system can a ball bearing be used in
Fixed
A floating bearing is normally what type
Roller bearing
Roller bearing parts
- Outer race
- Inner race
- Rollers
- Cage
Which forces can a roller bearing not transmit
Axial forces
Why are oil dampened bearings used
To reduce the dynamic loads from the rotor to the case
What type of bearing can oil dampened bearings be
Roller or ball
What reduces axial loads on the fixed bearing
Pressure balancing
Methods of feeding oil to bearings
- Direct lubrication
- Under-race lubrication
