ABSTRACT: h1xistinS methods of measuring axial stresses in steam
turbines suffer from a number of defects. Special spring
supports are required in the thrust bearing if it is intended
to use resistance strain gauges and so this method is mainly
used for large turbine sets. The method of measuring the
temperature on the bearing pads that is sometimes used is not
always applicable as is demonstrated by experimental curves
which show that the linear relationship between tempeL-ature
and load which is usually adopted is only valid. at a partic-
ular speed and over a narrow load range.
Accordingly a method was developed to measure the axial
stresses in steam turbines from the pressure of the oil film
in the thrust bearing. The relationship between the maximum
pressure in the oil film and the thrust on the pad was calcu-
Card 1/2 bated. It is in practice convenient to measure the pressure
in the so-called ''centre of pressure" of the pad. A theoret-
ical basis for this method is given. Tests were made on two

kinds of pad. Small holes were made in the face of the pad and
led to manometers through copper tubes %,fnich are sufficiently
flexible to permit movement of the pad. Ordinary manometers can
be used as great accuracy is not required. The results of the
tests are shown in the form of a graph and show some divergence
from values calculated from existing theories. Measurements
made in this way may be used for other purposes such as for
checking the operation of compensating devices of thrust bearings
which should ensure even distribution of the load between the
pads and an example of this kind is given.
The comparative simplicity of the measurements and the uni-
versa,lit-y of this method for all designs of thrust bearings make
it possible to use it for investigation of the operation of thrust
bearings in operating conditions and for the adjustment of steam
turbines in cases when the strain gauge method cannot be used for
one reason or another.
There is an editorial note that until further expe rience has
been acquired the method can only~be recomm nded for turbines of
less than 25 01. There are 5 fi~1res and 2 Slavic references.

ABSTRACT; The.authors discuss difficulties associated with the use of water-lubricated
bearings in high-speed turbine units. Some of these difficulties are the low viscosity
qf water as compared to~turbine lubricants and the difficulties of machining materials
suitable for operation under conditions of high temperature and pressure. The main
difficulty however is the viscosity of water which produces a very thin lubricating
lVer. The thickness of the layer permits additional friction by particles suspended
.,~the water. The authors propose the use of hydrostatic bearings which ensure a suf-
foieritly thick lubricating layer independent of lubricant viscosity. Such bearings
,e widely used in chemical machine building. These bearings are based on the desired
inciples, but still have many disadvantages. Therefore bearings were developed and
sted vhich are called "combination bearings" incorporating both bydrostatic and

~these data under operational conditions. The bearing material~ssr the main factor in
determining optimum bearing construction. Bearing materialshave to satisfy the fol
loving requirements: 1. they must be highly resistant to corrosion and cavitation;
2. they must be resistant to scratches and must have good ran-t characteristics at
both high and low speeds; 3. they must have good wear resistance under conditions of
semi-fluid friction, and in particular must be vear-resistant with respect to abrasive
particles in vater. As .a result of several yeare-of-operabienaar e*perieaee,-OF-40-1--:-

comparatively low run-in properties and a high coefficient of expansion. All bearing-.
designs considered in this article are made of this material. Four different types of
combination bearings are tested. A diagram 'is given shoving the temperature for the
internal surface of the bearing inserts. Tests show that local beating of bearings is
the main source of failure. Local thermal deformations affect the inserts and reduce
cooling for the heated zone. The continuation of this process causes binding betveen-
shaft and bearing. Three of the four types of b~ja~ing de Rns tested suffer from
these defects, while the fourth type (sii, fie-w_e_T-do_ei' not. This i fi-g J -s -de-s'gn~e-
so that expansion due to beat both-under normal and under emergency operating condi-
tions does not reduce the clearance between shaft and bearing. The bearing inserts
have a complex shape and are made so that the support surface is composed of four
flekibie elements. They are threaded in place, and in the event that fluid pressure
falls., the shaft rests on the two lower lobes. Under these conditions, a vedge-shW4.
