The function of thrust bearing uses is to bear the axial thrust of rotor in operation and to determine and maintain the axial mutual position between rotor and cylinder of steam turbine.
Thrust bearing uses can be set as a single type, or can be combined with the support bearing as a body, known as joint type (thrust support joint bearing), according to the structure shape can be divided into multi-jaw type and fan tile type, now commonly used for fan tile type.
The main structure is composed of working tile, non-working tile, adjusting shim and installing ring.The two sides of the thrust plate are respectively installed with 10 ~ 12 working tiles and non-working tiles.Each tile is installed on the mounting ring.The working tile bears the forward axial thrust of the rotor, while the non-working tile bears the reverse axial thrust of the rotor.
The moving distance of the thrust bearing uses disc between the working tile and the non-working tile is called the thrust gap, which is generally not greater than 0.
Thrust bearing uses is a kind of separated bearing. The shaft ring and seat ring can be separated from the components of cage and steel ball.The shaft ring is the ring matched with the shaft, the seat ring is the ring matched with the bearing seat hole, and there is a gap between the shaft.Thrust ball bearing can not accept radial load, the limit speed is low.
Thrust bearing uses is only applicable to bear one side of the axial load, low speed parts, only applicable to bear one side of the axial load, low speed parts, such as crane hook, instant water pump, instant centrifuge, jack, low speed reducer, etc.
