The bearings used in turbojet engines are mainly used to support and position the bearing discs between the rotor and stator, while reducing friction and friction losses during operation, and improving the efficiency and reliability of the engine.
The working principle of turbojet engine bearings is basically the same as other types of bearings, mainly achieving relative motion between the rotor and stator through friction and rolling. Different types of bearings may have different internal structures and friction modes.
For example, the ball in a ball bearing can roll between the inner and outer rings, thereby reducing friction and loss. In roller bearings, the rollers are usually cylindrical, conical, or drum shaped to better withstand axial and radial loads.
The bearings of a turbojet engine need to withstand harsh working environments such as high temperature, high pressure, and high speed during operation. This requires selecting appropriate materials, designing reasonable structures, and adopting high-quality lubrication systems to ensure the reliable operation and durability of bearings. In order to avoid losses caused by friction, reduce Mechanical efficiency and cause unnecessary failures, technical requirements and operation details should also be paid attention to during installation, lubrication and maintenance.
