Abstract

PURPOSE:To give the damping action to a rotary shaft system also in its thrust direction so as to prevent a trouble caused by turbulence, by both supporting thrust plates through springs and filling a space between the thrust plates and supporting beds with oil so as to form a squeeze oil film. CONSTITUTION:Thrust plates 9a, 9b are fixed to supporting beds 10 respectively through springs 11a, 11b. Further a clearance between the thrust plate 9a, 9b and the supporting bed 10 is filled with oil supplied from a supply oil hole 12 provided in the supporting bed 10, and the oil is sealed by seal plates 13 protruded from the supporting bed. The thrust plates 9a, 9b, tending to rotate in the same direction as rotation of a rotary shaft by viscosity of an oil film in a clearance between the thrust plates and a thrust collar 8 but being locked also in a rotary direction by the springs 11a, 11b, form oil films 14a, 14b, being a squeeze oil film of no oil film rigidity, between the thrust plates 9a, 9b and the supporting beds 10.

Nuclear power plants, thermal power plants, and other power plants that are equipped with steam turbine generators are constructed with seismic design (2) safety evaluations, and they are designed to withstand earthquakes (2). Operations are being carried out to reduce and prevent damage and damage accidents caused by the activation of various protection systems. 2L. Figure 1 shows the large-scale rotating machinery installed at the thermal power plant iK, where the steam turbine generator 1 includes a high-pressure turbine 2, a medium-low pressure turbine 3, and a turbine generator 4. -f: and connect them to each other (two directly connected rotating shafts 5 have a plurality of journal bearings 6 (six shown)
Furthermore, its position is set by a slant bearing (7) in the direction of the rotating shaft (in the thrust direction). It is necessary to monitor the vibrations of the journal bearing section (two installations In many cases, vibrations in the directions perpendicular to the axis (vertical, horizontal) act in pairs, and since the directions perpendicular to the axis are supported by multiple jar-reel bearings, a large tolerance for earthquakes (in contrast to the two (L) However, in the thrust direction (1), the rotating shaft system is more susceptible to external disturbances such as earthquakes (2) because the generated inertial energy is received by a single thrust bearing, the rotating shaft system is insufficient for the Taiji Exhibition, etc. In addition, since the mechanism by which ground motion occurs is extremely complex, a one-rotation reader is installed to predict the direction in which seismic motion will occur and prevent it from acting in the thrust direction. Fig. 2 (An example of the structural diagram of a two-pronged thrust bearing. p, there are thrust plates 9a and 9b on both sides, which are fixed to a support stand 10. A streak collar 8 and a thrust plate 9a,
In 9b, 1tiJ' and 12, the oil supplied from the t oil impregnation hole (not shown) rotates the stripe collar (forming oil marks on both sides).Then, when thrusts F and 6E occur, the thrust collar rotates. That direction (1 side 9 thrust position - 8
and IU of thrust grade 9a] has oil film thickness C1t.
The mechanism is such that a new oil film is formed and a pressure of 96 is generated, resulting in thrust F and Dh. Also, an oil film with a thickness C2 is formed between the thrust collar 8 and the thrust plate 9b in the reverse direction. These oil films are formed by the oil C2 that flows with the rotation of the thrust collar, and have the characteristic that the damping effect exerted by the system (2) is small. There is a mechanism.Fang 3 d i 2 is the thrust bearing's striped collar and thrust 7'' rate and 1/,) IU

There is a thrust on the rotating shaft system. As shown in Figure 2, the speed is C, and the speed is 1Il.

Here, we will consider a seismic wave with a large acceleration tl''m.Seismic waves (2) are known to contain frequency components in the soil with a general ratio of 420 to 20. shows the frequency component of the seismic wave, and within this range there is a thrust direction natural frequency ω1 or C2, and the thrust direction (-
When a large seismic wave acts, the rotating shaft system may resonate in the thrust direction at a frequency of ω or C2. In addition, only C2 is within the seismic frequency range (if there are two, a resonance phenomenon will occur only when an inertial force greater than the thrust acts in the opposite direction to the thrust, but changes in the thrust due to operational conditions or the seismic response of the building) Considering this, there is a high possibility of this happening. Moreover, as shown in Figure 2 (1), due to the structure of the thrust bearing, only the natural frequency in the C2 direction, which is the direction in which the oil film becomes thicker, is 201 (z or less). There are many cases where two things happen.-If the seismic waves and the rotating shaft system resonate, the thrust bearing (-) will not have the effect of reducing the vibration, and the seismic waves will
The vibration is very strong and the inertial energy is received by a single thrust bearing. There were two drawbacks: damage to the entire rotating shaft system.

An embodiment of the present invention will be described below with reference to FIGS. 4 and 5. FIG. 4 is a cross-sectional view of a thrust bearing according to the present invention (1), in which thrust plates 9a and 9b are fixed to a support base 10 via springs 1], a, and Ilb, respectively.The gap between the thrust plate and the support base The thrust plates 9a and 9b are filled with oil supplied from an oil supply hole 12 provided in the support base and sealed by a seal plate 13 protruding from the support base.
Due to the viscosity of the oil film in the gap between the
The rotation of the rotary blade (2 is also restrained. Therefore, the oil M14a formed between the strip plate and the support base (2) is
14b is a squeeze oil film having only a damping effect without oil film rigidity. If this squeeze oil film changes with a speed greater than the vibrations on both sides forming it, a pressure that prevents its change will occur and a large damping will dampen its vibrations. It has the characteristic of imparting an effect (squeeze effect) to the rotating shaft system.Since the thrust plate is supported by a spring, the spring stiffness value is determined as follows.During normal operation (for example, thrust) F If it is acting in the direction shown in Figure 4 (two directions), as mentioned above, between the thrust collar 8 and the streak plate 9a (the second is the oil film (not shown) that generates an unbalanced force). ) is formed.Therefore, the spring 11a (2) similarly has a force that makes it engage with the thrust F. Also, the spring 11b (2) on the opposite side has almost no force working. The squeeze oil film thickness that can be achieved is 0.1 to 3 #
It is good to have a spring of +1iIIO4ll.
a, llb can ensure the squeeze oil film thickness during normal operation. υ should be determined.Also, if the rigidity of f2 is increased more than necessary, the thrust plate will be less likely to vibrate.
Squeeze effect no longer occurs - 1:9° Therefore, the spring stiffness is the same as that of Streak 8 and Thrust Gray 9a (2) It is also desirable to reduce the stiffness of the oil film produced.

However, the vibration is absorbed by the squeezing effect of the squeezing oil films 14a and 14b provided between the streak plate and the support base, and the vibration is attenuated, and the vibration of the entire rotating shaft system is also attenuated. Therefore, the present invention (two thrust bearings) can provide a large damping effect to the rotating shaft system against vibrations in the thrust direction (two thrust bearings).
