The starter representing the electric motor посто-янного of a current with mixed excitation is
applied to start-up of the engine. Элек-тродвигатель such design develops the growing twisting
moment at increase of braking of an anchor that facilitates start-up двига-теля. Force of the
current consumed by a starter at his(its) work, does not remain to a constant and depends on a
condition of the storage battery, сопро-тивления an electric circuit and frequency враще-ния
anchors. Owing to the big section and ма-лой lengths of conductors of a winding of an anchor
and обмот-ки excitation the starter has very small resistance, therefore at the moment of
inclusion of a starter, and also at full braking яко-ря when in his(its) winding it is not induced
about ратная ЭДС. Starting force of a current, in particular at a starter 4216.3708,
reaches(achieves) 600 And, at idling an anchor is reduced up to 85 And. With increase of force
of a current, потреблемого start rum, grows a magnetic stream of excitation which cooperating
with a magnetic stream of an anchor, creates the growing twisting moment that facilitates
rotation of a cranked shaft дви-гателя. Twisting moment reaches(achieves) the greatest size at
full braking an anchor - at a feed(meal) of a starter from serviceable and completely charged
storage battery when in a circuit of a starter force of a current reaches(achieves) макси-мальной
size (and a magnetic stream макси-мальный). On the engine of model 2106-70 lips навливается
a starter 35.3708 or 425.3708, and on engines of models 331 and 3317 - a starter 4216.3708.
Both starters represent themselves two-port electric motors of a direct current with the mixed
excitation, электромаг-нитным inclusion шестерни a drive and дистан-ционным management.
Starters are equipped with the coupling device for connection and разъе-динения a cogwheel of
an anchor of a starter with a gear wreath of a flywheel of a cranked shaft of the engine. On a
design and a principle дейст-вия starters are identical, differ only on мощностным to
parameters, a way of fastening on the engine and connection of electricity cables. Both starters
are located in a back part of the engine: a starter 35.3708 from the right party(side), a starter
4216.3708 - with left. The device of a starter 4216.3708 (fig. 40) one has 4216.3708 Starter four
poles on which располо-wives of a winding возбулодения, three of which are connected among
themselves consistently, - in parallel. The anchor 72 starters rotates in two брон-зографитовых
bearings, lips новленных in a lobby 63 and back W крышкак. On a back cover укреплены two
isolated and two closed on the case 74 щеткодержателя in which brushes are placed. Isolated
щет-кодержатели are connected among themselves copper пе-ремычкой. The end of three
consistently connected windings of excitation is brought to one of them. The second end of these
windings at is connected to a clip of the traction relay. Brushes at жимаются to a collector
springs. On the end of a shaft of an anchor there is a drive of a starter, with worth from
шлицевой cartridges 65 and муфты with a cogwheel 68. Втул-ка 65 the opportunity freely has
69 free courses to move ся on лентонной to a groove of an anchor and you are connected with
приводным a cogwheel 68 to the help муф-69. Муфта a free course of roller type consists of the
external holder fixed on a flange шлицевой of the cartridge 65, internal обой-we, made as a
single whole with a cogwheel 68, and rollers with плунжерами and пружи-us located between
holders in grooves and jacks of an external holder. At inclusion of a starter rotation from a shaft
of an anchor is transferred through the cartridge 65 to an external (conducting) holder муфты 69.
At rotation of an external holder of a role ки, being shifted under action плунжеров with
пру-жинами in a narrow part of grooves, get jammed an internal holder, and both holders with a
cogwheel 68 start to rotate as one це-лое. At gearing a cogwheel from veins цом a flywheel
start-up of the engine is provided. After start-up of the engine frequency of rotation махо-вика
will exceed that his(its) frequency of rotation, кото-paradise was during start-up of the engine,
and already the flywheel will start to rotate a cogwheel 68 with an internal holder муфты, with
the greater frequency of rotation, than frequency of rotation of a shaft of an anchor of a starter
with an external holder муфты. Thus rollers муфты, being shifted because of friction about
внут-реннюю a holder aside the expanded part of grooves of an external holder, расклинят a
holder, and twisting moment from a flywheel will not be переда-ваться on a shaft of an anchor
of a starter, and gear to лесо with an internal holder it will be free to rotate on a shaft of an
anchor. Inclusion of a drive is carried out electromagnetic traction ре-ле which is attached by
two bolts to кор-пусу a starter. The relay has the coil with втяги-вающей 66 and holding 60
windings. Внут-ри coils there is an anchor 62, a shaft to торого is connected to the lever 64
drives start ра. On other party(side) of an anchor the dam 57 is fixed кон-тактная. On an anchor
the returnable spring is established. The starter works I follow щим in the image. At turn of a
key of the switch of ignition in the position appropriate вклю-чению of a starter, a current from
an accumulator room ба-тареи through the plug of the lock of ignition acts on both windings of
the traction relay, creating in ка-тушке a total electromagnetic field. Under action of a magnetic
field the anchor traction ре-ле is involved in the coil and by means of growl га 64 drives and
поводковой муфты enters a tooth чатое a wheel 68 in gearing with a wreath махо-вика. At the
end of a course an anchor with the help contact ной plates closes both clips of the traction relay,
including a starter, and through a contact plate 57 closes накоротко additional resistance of the
coil of ignition (only at a starter of the engine 331). At the moment of short circuit of clips of the
relay occurs закорачивание втяги-вающей windings then the anchor of the traction relay is kept
in the involved position only by holding winding. After start-up of the engine and installation of
a key of the switch for жигания in a starting position a current in a circuit пре-рывается, the
anchor of the traction relay under action of a returnable spring comes back in первона-чальное
position and deduces a cogwheel of a drive from gearing with a wreath of a flywheel. Thus the
contact plate disconnects contact ные bolts 54. If at inclusion of a starter end faces зубьев a
cogwheel of a drive слу-чайно will be rested against end faces зубьев a wreath of a flywheel the
lever of the traction relay relocatable втя-гиваемым by an anchor, will compress a buffer spring
шлицевой cartridges 65 and when the contact disk will connect a starter to an accumulator room
батарее and the anchor of a starter will be turned, the compressed buffer spring will enter, a
cogwheel of a drive in gearing with зубьями a wreath of a flywheel. At for едании a cogwheel
of a drive of a flywheel at the moment of interruption of a current in a winding of the traction
relay поводковая муфта, consisting of two on ловин, under action of a returnable spring яко-ря
will overcome effort auxiliary пружи-ны, located with the left party(side) муфты, and will
enable to allocate(remove) a contact disk from clips of the relay, having switched off a working
circuit start ра, than and will prevent the category of the battery.
