A- PURPOSE AND SPECIFICATIONS
Anchor _Gear
The anchor gear serves for dropping and hoisting the
ahr'hor from the submarine in the surface condition.
The anchor gear is actuated by an electrical anchor and
warping capstan provided with an emergency hand drive.

B. GENERAL AND DETAILED DESCRIPTION
1. Anchor Gear
(See Appendix 1)
The anchor gar consists of: bower anchor 9, anchor
4 , electrical anchor and warping capstan, chain locker,
st-_-pper 5, guide rollers 3 and 7 and bitter end release l0
A,1 bower anchor with turning flukes and a shortened shank is
_oLatet in the starboard chain hawse,rfear frames 1 and 5.
The anchor is secured to the anchor chain through swivel-
E.
The bitter end of the anchor chain is secured to the hook
Ie bitter end release in the locker. It is released fro= th-
c,r.rd compartment by means of hand drive 11 installed on the.
tcmed bulkhead. When the anchor is droppec or hoisted, the
cnain movement is directed by guide roller 7 and fair-lead rol-
3 and finally stopped by screw stopper 5.
The screw stopper is controlled by a drive comprising hinge
shafts 2 and 16, bevel drives 6 and 1 and hand drive 13.
Twin bevel drive 1 actuates screw stopper 5 both from the
compartment and from the superstructure deck.
The wheels of the bevel drives are lubricated periodically
..-ith-grease and the shafts of the bevel drives are lubricated
means of screw-cap lubricators. -

worm self.-braking reduction gear interconnected through an
elastic coupling and mounted on one base frame.
a) Worm Reduction Gear
(See Appendix 10)
The worm reduction gear consists of steel cast body 142
split in the horizontal plane, worm 145 and worm wheel 141.
The worm is mounted in the body in two sleeves 144 and 146 on
roller bearings. The end of the worm shaft protruding from the
body is sealed in sleeve 146 with a gland. The worm wheel consists
of a steel hub z.nd a bronze rim. Wheel lul is mounted in the
body on the bronze bushes.
The worm pair and the lower support of the wheel are lubrica-
ted with oil filled directly inside the reduction gear body. The
upper support is lubricated with grease by means of a screw-cap
lubricator.
The oil level in the reduction gear body is checked by means
of oil level indicator 143. For filling and draining the oil the
body is provided with plugs.
The hand drive of the capstan is made-in the shape of a de-
tachable chain wheel with a closed chain. It is installed for
the ,ime when it is supposed to be used on the end of the elect-
ric motor shaft.

misalignment by the bead and limiting ring 152. The supporting
bushes are lubriC'e..ted by means of the screw-cap lubricators.
Control ler Drives
(See Appendix 12)
The drives of the forward and after capstan controllers are
similar in design.
The controllers are mounted on the frames installed on the
ceiling -J IN*, means of shock absorbers. Twin bevel drive 165 allows
control of the controllers both from the compartment and from
the upper deck.
Deck socket 167 is connected with the bevel drive through
elastic clutch 164 and hinged actuating shaft 162.
The shafts are lubricated with grease by means of the screw-
C 7;
engagement of the bevel gear wheels is
lubricated with grease periodically packed into the body of the
bevel drive when its cover is removed.

For securing the warping ends removed from the capstans in
-T:e forward and after parts of the superstructure provision is
for supports 172 of tubular cross-section with guide
zushes 173 and nuts 171 for locking the warping ,ends.
The supports are installed on the pressurellUllin the super-
structure. The warping ends are secured for sea by the threaded
shafts installed on them.
When the warping ends are installed on -the capstan, the su
ports are used for the covers taken off the end_ faces of -t

Telescopic Bollard
(See Appendix 15)
The telescopic bollard consists of two tubes 1E7
moving one inside the other. The direction of mr-vnt
tube 187 with a blind flange on top is ensured by
bushes 189 press-fitted inside outer tube 188.
Screw 190 sliding along the longitudinal slot of th
tube keeps the inner tube from turning and when the inner

Appendix 16)
Steel cast body 197 of the warping guide is provided
three lugs. Two of them bolted to the base hinges serve as an
ax1e for the guide and the third is designed for securing
ide with rod 196 in the working position for mooring.
After the roc is extracted, the guide is secured under tne
CeCP= for sea.
The upper part of the warping guide body is provided with
