ABSTRACTi The possibility is explored of using the formulae and methods of
mathematical statistics to characterize the properties of industrial
ceramet materials manufactured by standard processes; the output
of semifinished electric brushes at the "Elektrougli" plant (trans-
lation: Electrocarbons) is taken as an example. Included are tables
and diagrams representing statistically a number of the technological
characteristics of semifinished electric brushes (Cu-graphite,
Cu-graphite-Pb, and others). The arrangement and distributions
exhibited make possible certain inferences concerning the charact-
eristics of mass-produced semifinished electric brushes and make

ABSTRACTs This article gives the results of investigations of the transitional
voltage-drop in a pair of brashes and the coefficient of friction of b
brushon on a commutator; also the influence of certain factors on
these characteristics. Special test rigs known as short-circuited
collectors with reciprocating traverse were used, but unfortunately,
the accuracy is poor. There are various chance errors and, therefore,
only statistical and not functional relationships can be established
between the variables studied. A brief review is then given of the
method of correlation analysis which was applied to the relationship
between the current-density in the brush and the transient voltage-
drop at the sliding contact. Well-defined relationships were
established, as will be seen from the curves given in Fig.1 for test
results on materials grades )r4, and tl,~C7. Each line on Fig.1
relates to one pair of specimens. By mathematical treatment of the
data given in Fig.1 it was posaible to graph correlational
relationships in Fig.2, which also includes similar graphs for

represents the curves of Fig.2. 11iis table includes cunstarits which
are tabulated for the different materials in Table.1, and from these
values the voltage drop is calculated as a functional current for
the various materials. (The sr"a formula may be used to determine
the expected scatter of results; the constants required for this
purpose are also given in Table 1. A volt-ampere characteristic for
material _4r-Z1 calculated in this was is given in Fig.3. The
correlation method was also applied to experimental data relating
the coefficient of friction to the circumferential speed of the
commutator. The appropriate relationship for various kinds of
material are plotted in Fig.4. The graphs are then expressed
analytically; the appropriate constants are in Table 2. An example
of friction calculations is given. The remainder of the article is
concerned with the permissible limits of application of the results
given. In conclusion, mention is made of tho.influence of temperature
on the characteristics studied. With a sliding contact in the absence
of current, the influence of temperature is large, but is much greater
when current is flowing. Published data states that in the temperature
range of 70 - 1100C the voltage drop and friction fall, but if the
temperature is further raised they commence to rise again. The

ABSTRACT: In the present paper forrlula (7) for the specific losses

the majority of practical caoen where nli-1ing contacts are

into the above formula the values of A (free term of the volt-

volt-ampere characterintic equation), C (free term of the
friction characteristic equation), D (angular factor of the
friction characteristic equation). Formula (7) aloo allows
to solve the problem of the choice of the aapi;ropriate sliling

at various values of A,B,C, and D, i.e. among variouB types

particular importance. If B > 0.02, i.e. if the volt-ampere
characteristics is markedly inclined, the curves of total loss
show a more or less distinct mininum. The new data expo!jcd
in the present paper permit to give the concept of rominal
current density a definite physical significance. It is
suggested to regard the nominal current density in the ~lirling
contact of electrical ma-chinen as being that particular current
density, in which the total loss curve shows the mini-7un
value at a certain velocity v. It can be seen from the
table that th+ominal current density lies in the ringe of
11 to 15 A/cm2 in the case of "bl-ckll (without metal)elf,~ctric

ABSTRACT: To meet present requirements, brushes must have
improved commutating properties, mLEt be capable of operating
at higher speeds and current-densities and must resist wear.
The commutating properties of a brush depend on its structure.
vatural graphite compositions are the wrst in this respecti
the beat are disperse carbonacious materials of the type of
carbon-black or wood charcoal powder. ~A series of carbon-
black/graphite brush materials has been developed to give
brushes with a range of commutating properties. They are used
in blooming mill generators but althouGh commutation is
improved the brushes have a short life and it is becoming
important to reduce the wear of brushes.
Much can be achieved by the use of appropriate binders in
combination with carbon-black. Brush wear can also be reduced
Cardl/4 by improving the commutator surface; an effective way of

Problems in the Production of Electrical Brushes
11.0- 58-5-6/25
doing this is to use the so-called lubricating brushes of
natural graphite, which give the requisite special finish
to the commutator. Thus', brushes of the type required to
give good commutating properties are used in combination
with others that help to form the commutator surface. This
arrangement is described at some length.
It is important to be able to ran brushes at higher commu-
tator surface speeds. Reduced mechanical friction losses and
a lower natural frequency of vibration of the brushes are
also desired. To do this it is helpful to reduce the
pressure on the brushes and to make them lighter in weight.
Light-weight brushes can be made of porous materials. Tests
have been made on trial samples of brushes working on
commutators with peripheral speeds of some 40 - 50 m/sec.
At present, current densities in sliding contacts are
governed by standard rules which set current-density limits
for -art-icular grades of brushes. . The current densit-'y
rises from 6 Alcm2 for pure carbon compositions to 20 A/cm2
for brushes containing metal. As the current density is
increased the total contact surface is reduced. The
Card2/4 mechanical losses fall ~Lnd the electrical losses rise.

110- 58 - 5 .612 5
Problems in the Production of Electrical Brushes
Consequently, the total loss curve has a minimum value and
is of the shape shown in Fig.l.
Temperature limitations on brushes are usually imposed not
so much by the brushes themselves as by the other materials
used in the machine. In particular, it may not be possible
to maintain the requisite finish on the commutator if the
brushes are not of suitable composition. Brushes are made
that are atle to work at commutator surface tedperatures of
120 - 180 C. Brushes of particularly good mechanical
properties are required for electric traction applications.
Recent developments in this field have called for improved
brushes. One type of material that meets the new requirements
is grade EG-2P-2. Its special feature is that the basic
coke-graphite structure is very porous. These 1gres are
impregnated with carbonacious substance, which is ~;toved
to form a further coke basis linked with the first one. The
resulting material is very strong.
The operating properties of brushes are improved if they are
worked in an inclined rather than a radial position.
Inclined brushes are widely used in equipment for aviation,
Card3/4 automobiles and tractors but, in general, the electrical

Problems in the Production of Electrical Brushes 110-58-5-6/25
engineering indust:by underestimates the importance of this
factor. Another and very effective measure is to use a
sectional construction in which the brush is sub-divided.
Graphs of zones of sparkless opeiation when using solid and
sub-divided brushes on a machine are shown in Figure 2.
Considerable improvement results from sub-division and the
true area of sliding contact is increased.
A number of constructions of brushes are illustrated in
Figure 3. A further possibility is to use sub-divided brushes
in which different parts are made of different materials;
the leading ed-e is madia of natural graphite and the trailing
edge of hard carbon-black composition. This gives the same
effect as mixed arrangements. Very often, considerable
improvement can be effected without changing the brush-
holders. There are 3 figures and 3 references, 1 of whicA
is French and 2 German.

ABSTRACT: Some regularities. in the changes of properties of powder materials
are described for forming an electric sliding contact, depending on the ratio of
graphite, carbon black, and copper introduced into these materials. The characte.
istics examined include: elastic modulus of the first type, specific weight,
resistivity, transient voltage drop, friction coefficient, wear, and correlation
index. Some of these characteristics were analyzed simultaneously; the relations
existing between pairs of characteristics are described. The authors note that 'he

above regularities were determined without data of actual tests. The factual data
for plotting the curves were obtained on the basis of earlier industrial research
with the use of mathematical 13tatistics. Orig. art. has: 1 figure. [Based on

PERIODICAL: Avtomobil'naya promyshlennost', 1958, Nr 10, p 12 - 15 (USSR)
ABSTRACTt The Tsentrallnoye konstruktorskoye byuro toplivnoy appara-
tury - TsKB TA (Central Designing Office for Fuel Appara-
tus) developed an electronic fuel injection control system.
Figure 1 shows the circuit diagram of this system. It con-
sists of a transistorized kipp oscillator, a distributor and
electromagnetic injection noz7les. The electronic unit is
controlled by various transducers, for example a vacuum trans-
ducer in the intake channel, engine temperature transducer,
choke transducer and a transducer for sudden accelerations
of the engine. Tests were conducted on an ordinary one-cy-
linder 111-hend engine "L-2". A graph (Figure 9) shows that
the engine with electronic fuel injection control possonnes

is now testing the electronic fuel injection control system
on a four-cylinder engine and on a vehicle. There are three
graphs, six diagrams and 1 circuit diagram.

Title :0"~the distribution of stresses along the contact surface in the
hot fitting of a constant-thickness disc on a solid shaft
Periodical Izv. AN SSSR. Otd. Tekh. Nauk 4, 23-42, Apr 1955
-Abstract Studies the stress distribution when a disc (or bushing) is
fitted onto a shaft. Presents a method for the theoretical de-
termination of stresses based on the work of A. 1. Lur'ye. The
suggested method differs from previously proposed ones in that
it takes into acccount the friction on the contact surface.

ABSTRACT: The author has discussed earlier (Ref 1) the stress
distribution along the surface of contact of a long massive
shaft in fitting a stationary disc of constant thickness
with a given tolerance for the case when the outside radius
of the disc is considerably greater than the inner. This
paper gives the solution of a similw problem for a rotating
disc for different ratios of the radii and given boundary
conditions on the outer surface. The case of uniformly
distributed loading is discussed in detail. Graphs of the
contact pressure distribution for various angular velocities
are given. It is noted that at the operating rpm, as in
the whole range of angular velocities over approximately
half the contact circumference, the required pressure
exceeds that given by Lamele well-known formulae for

pressure on the sides of the discs are given for different
combinations of parameters depending on the relative
contact circumference. There are 6 figures and 4 Soviet
references, and 3 tables.
