PRODUCT DESCRIPTION
Two kinds of bearings used in Steam Turbines: thrust bearing and supporting bearing.
- Thrust bearing: It is used to balance the axial thrust of the rotor and establish the dead point of rotor expansion, so as to ensure that the axial clearance between the moving and static parts is within the design range. It is widely used in steam turbines, water turbines, water pumps, etc.
The main material used for the thrust bearing: steel billet + Babbitt alloy (also known as white metal). White metal can be melted when the shaft temperature reaches about 110°C, which increases the displacement space of the large shaft, thereby protecting the main shaft and preventing the dry friction of the thrust bearing caused by the large axial displacement of the large shaft. The traditional bearing bush is also made of tin bronze, steel billet + fluoroplastic. The fluoroplastic material has a small friction coefficient and is suitable for higher temperatures. There is no need to scrape and grind the tiles, and it will not burn the tiles due to oil cut-off.
- Supporting bearing: used to support and position the bearing, so that the bearing has sufficient rigidity and stability when rotating at high speed. Sliding bearing shells are usually made of low-friction materials, such as aluminum bronze or white metal, to reduce frictional losses and wear.
