ABSTRACT- The author presents a brief review on the development of ferrous
metallurgy in the Sverdlovsk economical district after the re-
organized management of the industry and construction, including
outlooks on the period from 1959 to 1965. In the enterprises
subordinated to the Administration of ferrous metallurgy,
120,000 workers, technical personnei anci employees are occupied.
The coefficient of useful volume utilization of blast furnaces
was 0.78 in 1957, (the most efficient furnace, attendants of the
Serov Plant brought it to 0.64); steel yield was 7.6 ton,per
1 m2- The use of 0 at the Nizhne-Tagillskiy Metallurgical
Combine raised steei production, by 15 - 2076. The Institute or

ABSTRAOT; The results of testscarried out with specially-cut gear
wheels of normalised 0.45% C steel are reported. The surface
finish corresponded to the 6th grade and was inspected by a
binocular microscope. Different root radii were obtained by
shifting the tool in the hobbing machine. The tests were
carried out in a pulsating inertia type of fatigue testing
machine, where the engagement of the gear wheel with a rack
was simulated. Stress versus number of reversals curves are
given for different ratios of tooth root radius to tooth thick-
ness and of tooth engagement heights to tooth thickness. An
empirical formula is developed from these curves in which the
effective stress concentration factor is expressed as an
exponential function of these variables. The stress concen-
tration factor is plotted in a graph against the number of
teeth for different tooth correction factors. There are 3
Uardl/l graphs and 2 Slavic references.

TITM A Device for the Testing of Fatigue in Gears (Ustanovka dlya

PMIODIGAL: Zavodsk&ya La boratoriyao 19571 Vol. 23, Nr 11, pp. 1383-1384 (USSR)
ABSTRAM In order to avoid,trouble in operation causad by the breaking of gears
in gear-oouples as & result of fatigue, gear testing plants are used#
one of which is described by this paper. Such & device makes it poa-
sible to detect any kind of azymmetry, be it in the fom of faults in
production or in form of a bending of the gears or of wear. Such a de-
vice is, in principle, based upon a device that makes it possible to
imitate the real conditions of the toothing of the pair, and thus to
control the toothing. The pair of gears to be investigated is mounted
on two shafts located opposite to each other at a certain distance,
and at the sides they are fixed by plugs, which are fastened to the
base plate and protrude between the gears. Into the space between this
pair of gears the aforementioned testing device is introduced, so that
it occupies a "weight-balancing" position while it rests on both sides
against the gears. The device itself consists of a T-shaped head, the
Card 113 upper ends of which are fonnea in such a manner that they can easily

enter between the teeth of the two gears. Their position with respect
to the horizontal can be adjusted to any angle by means of a special
device. The entire testing apparatus is attached to a shaft which is
adjustably arranged in a position that is transversal to that of the
pair of gears. At,the lower part of the testing device there is a fly-
wheel, an the edge of which an exchangeable weight is fitted (because
of the centrifugal force). The flywheel is driven by belt drive by a
transmission shaft arranged in a somewhat lower position up to 3000
revs. per minute. The centrifugal force occurring on this occasion
exercises its influence on the-tooth of the pair of gears to be in-
vestigated. By suitable selection of the weight on the flywheel and/or
by adjusting it in the direction of the axis of the flywheel, it in
possible to create different momenta of stress acting upon the tooth,
which may lead to its breaking out (if damaged). For such a case a da-
vice is provided by means of which the testing apparatus is automti-
oally switched off. By suitable selection of the aforementioned moment,!
of stress and by means of a suitable adjustment of the points of the
teat apparatus it is possible to obtain an impression of the &symmetry
in the pair of gears under investigation and to determine the
Card 213 operation characteristic of this pair. The apparatus described in this

with a common massive and well fastened base plate (because of
vibration). For measuring the moments of stress each of the testing
devices in provided with an electric device for measuring resistance
consisting of a ferroresonance stabilizer, a rectifier, an amplifier,
an osaillogmph, and a vibrator, which are connected with the
four-armed bridge indicator mounted on the head of the testing appara-
tus. There.are 2 figures.

LARIODICAL: Vestnik Mashi-nostroyeniya, 1958, Ur 7, PP 39-40 (USSR)
ABSTRACT: An attempt is made to determine in the first approximation
the scale factor expressing the effect of size on.the
fatigue strength of gear teeth. The statistical theory of
Afanas'yev, N.N. ("The Statistical Theory of the Fatigue
Strength of Metals" published by Ac.Sc.Ukrainian SSR,
195-9) postulates the constant value of the product of the
orcss-se.:.ticnal area of the specimen and the k-th power
c.f the stress for infinite endurance. A tooth.is considered
simila-- t.a a notched test piece of rectangular cross-
section. The stress distribution across the weak cross-
sect-ion is assumed to follow a parabolic law with some
exponent of the parabola. The acale factor derived on
this basis is equal to the k-th root of the product,of two
ratios. The first ratio is that of,the squares of the
mod:dles, the second is the ratio of the tooth widths
expre-esed as multiples of the modules. The value of k for
gear teet-h has been determined by fatigue tests on a
Cardl/2 special test rig simulating the engagement of the'gearwheel.

as illustrated in Figure 2 showing the drop of the tooth
fatigue strength with a rising module. A gearwheel with
a mm mod-c.le -teeth, 10 mm wide, is suggested as a sui Lable
standard whee'L for fatigue tests. It follows that the
size factcr for fatigue stm~ength is the !0th root of the.
quotient of 40 divided by the square of the module in mm
and by the relative gear width. There are 6 figures

TITLE! A Device for Fatigue Tests of Not Round Samples (Prisposobleniye,

PERIODICAL: Zavodskaya Laboratoriya, 1958, Vol. 24, Nr 4, PP- 492-493 (USSR)
ABSTRACT: A simple device was developed to.be used with the machine of the
Veler types, which makes 'it possible to examine samples of differ-
ent cross, section with respect to their bending fatigue for any
coefficient of the asymmetry of the stress cycle. Investigations
were carried out in the regime of deformation constance. From the
sch-ems.ticai drawing it may be seen that, instead ofthe pincers
for round profiles,,two eccentrics are screwed on, and that the
necesuary total eccentricity can be attained by revolving the
lower of them. Modification of cycle asymmetry is attained by
changing the position of the sample.by means of ground bases.
Stress can be measured in two ways: by means of aclocklike indi-
cator or by means c.: wire resistance cells which are pasted on to
the sample. In accordance with the increase of stress,bending is
carried out in one of the two ways mentioned. The number of
Caxq 112 cycles is measured by means of a rotation counter. The device

TEXT: The numerical evaluation of the tooth.correction effect yields.
only very relative data as quoted in the existing sources of technical literature,
and,the data obtained, are contradictory in nature. Referring to a previous ar-
ticle by the author (Ref. 3: Vestnik mashinostroyeniya, No.. 3, 1957) he st&tes
in this article that experimental results made it possible to illustrate through
curves the dependence of the effective stress concentration factor Kcron the

mesh, and where the load at the tooth addendum may be considered as the point
of load application. By approximating the curves we obtain an empirical formula
for the YCr factor of 8 12 accuracy class gears (also applicable to class 7 with

The results calculated in accordance with this equality for gears with various
tooth numbers of the 8 - 12 accuracy class are plotted in the curves of Figure
2, and for gears.of the 1 - 7 accuracy class in the adja cent table. When.com-
paring the curves witheach other it can be noticed that an increase of the po-
sitive displacement of the rack-shaped cutting tool for the case of single-pair
mesh of gears with a low.tooth number,,z = 9,+' 20, leads to a considerable rim in
tooth strength (of*the order between 15 - 40 %); at a tootfl number z = 30 + 50
the tool displacement has practically no effect, and finally at a tooth number
z = 70 + 100 a sWh dpa ease in strength can be noticed. From the data given
in the table it can be concluded that gears in two-pair mesh, corrected accord-
ing,to both systems of the TsKBR., show.a.sharp increase of the flexural tooth
strength at a small tooth number rate (z = 10 + 12) as compared to uncorrected
gears; however, this increase is diminished by a rising transmission ratio. At
z = 15 + 20 the increase in strength is insignificant at a low transmission
ratio; it.grows, however, with a growing ratio. At tooth number (z;- 30) the
