Rotary Index Tables T Series – Translation of manual for use and warnings
1 MACHINE DESCRIPTION
N° 4 threaded hols for lifting
The rotary index table is a mechanical device that sets the output disk into intermittent motion.
It can be motor driven.
The square axis mechanical unit transforms the uniform rotation of the inlet shaft in an
intermittant rotation of the output disk by means of a cam and cam followers; the cam profile
determine the indexer’s transfer and dwell cycle:
The machine consists of a square axis rotary indexer and it is generally framed into another
machine.
2 FORESEEN AND UNFORESEEN USE
The rotary index table has been designed to set in motion equipment ( conceived and
developed by the customer, who is reliable for it), with mass, speed, movement law, system’s
rigidity, axial load, side load, torque within the limits set by the specifications shown in the
technical data sheets (see from page 16 on).
Should the indexer be used with higher loads than the ones mentioned in customer’s order, a
defective working may result, along with a premature wear of the system. Said operating
conditions can be anomalous also from the point of view of operator’s safety.
A dynamic shock during the deceleration phase hints at a load exceeding the one expected
when designing. The customer must carefully plan the overall safety conditions of the machine
designed to frame the rotary index table Autorotor and must take into account the specific
features of the indexer itself.
2.1 Table fixing
The rotary index table must be suitably anchored and supported according to its own weight
and to the loads applied to it (see pict. 1, pict. 2 and table 3).

2.2 Features of the tooling plate to be connected of the
indexer
They must be suitable for the table features.
2.3 Risk of crushing, trapping, cutting, friction; and that
pieces are projected due to the tooling plate and to
the parts/equipment moved by the table
Should the a.m. risks be there, suitable protection screens are to be prepared. They have to be
evaluated depending on what follows.
2.3.1 Motor stop in dwell position.
The table must not be stopped during the transfer phase. The cam holder shaft can be stopped
during the disk dwell position, that is when the masses are still.
The (optional) position sensing device triggering the motor stop during the dwell position has a
functional nature, and therefore it is not a safety device.
Should this stop have to be ensured to
protect the safety of the machine in which
the table is framed, then the a.m. sensing
device must be replaced with another
suitable one (possibly to be supplied by
Autorotor).
The position sensing device must be
adjusted while being installed (see. § 6).

table
2.3.3. Emergency stop
Although you mustn’t stop the intermittent units during the transfer time, the Autorotor table
is mechanically designed as to allow the emergency stop at any moment of the cycle.
Furthemore an electric braking system in countercurrent - within the current values set in the
table depicting the features of the electric system of the motor - can be added to the built-in
brake motor braking.
The stop during the displacement phase entails a peak torque on the table output disk due to
the inertia of the system causing a dynamic shock to occur, the intensity of which depends on
the cam position at the very moment when the stop occurs. The dynamic shock discharges
onto the intermittent unit and the reducer.
As the remaining life of the table is reduced by the stress of a dynamic shock, the use of
emergency stop as an ordinary cycle stop is forbidden.
2.3.2 Motor stop due to
power failure
The stop of the system is triggered by the
motor mechanical or dynamic brake if they
are there (See § 2.3.3 and § 4). Should the
calculated values still entail residual
unacceptable risks, interblocked protection
systems are to be applied, or a different
kind of indexer must be requested to
Autorotor.
6
Rotary Index Tables T Series – Translation of manual for use and warnings
A torque limiter between table and reducer, limiter which under emergency stop conditions
allows the motion to be continued and the kinetic energy accumulated to dissipate, reduces the
effect of the dynamic shock on the mechanical parts.
The emergency stop does not cause the motion to come immediately to a standstill; in fact the
output disk is likely to rotate, after the stop, for an angle, which depends on the initial mass
inertia of the system and on the instant when the emergency stop occurs.
The torque limiter must
be checked every now
and then to check that
the original setting figure
is kept.
In case it wasn’t, it has to
be set to the pristine
value.
The setting value is shown
on the records of order and
recorded on the sheet
product.

3 TORQUE LIMITER SETTINGS
Set out below is the information on the calibration of the joint in some typical configurations
(ring joint Rossi and STM joint).
The type can be detected by comparison with the photos on the following pages.
For further configurations, please contact After sales dept. of Autorotor.
3.1 Stm
Lock the motor shaft (it is already locked if the reducer’s reduction ratio is over 30:1 or if the
motor is a brake motor).
Remove the plastic ring which covers the adjusting ring (picture no. 13).
Gauge the sliding torque (picture no. 5) by means of a “tool shaft“ (helping shaft) and a
dynamometric wrench (picture no. 12).
Tighten the adjusting ring till you get the needed setting value (picture no. 6).
Rotary Index Tables T Series – Translation of manual for use and warnings

fig. 5 fig. 6
It is possible to apply the dynamometric wrench also to the opposite side of the table input
shaft: in this case, needless to say, please remove before the microswitch group (picture no.
7).
fig. 7fig. 8
The table no. 1 (supplied by the reducers manufacturer) gives only very rough data and can be
used only for a presetting of the torque limiter.
It is necessary to set the STM torque limiter at 20% more than the planned value because,
after each intervention, it doesn’t go back promptly to the previous setting value.
The best evidence of a correct setting is given by the table’s behaviour; the displacement
between stations must be smooth and the coming into dwell must be without vibrations or
bumps.
If the dynamic shock still shows, than you’ll have to tighten the torque limiter more than you
did. This normally means that the actual application data are different, and heavier, from the
ones Autorotor received to size a table. In this case please contact Autorotor and have the
table calculated again.
The adjusting ring is of the self-locking type, so it could be very hard to tighten; to evaluate if
the torque limiter can be tightened any further, check visually how much the springs are
compressed (picture no. 8).
If the torque limiter doesn’t work properly, please get in touch with Autorotor after sale service
to ascertain whether the technical data of the actual application are the same as the ones
given to Autorotor to size the table and, as a consequence, if the type and/or quantity of
springs is to be changed.
3.2 Rossi
Remove the joint with a stripper, after removing screw and lock washer (fig. 9).
Secure the joint in a vise or with a suitable tool, remove the screw (fig. 10) and unscrew the
nut with a spanner (fig. 11). Tighten the nut by hand until you can.
Tighten the key to the first section of interest: this position becomes the initial value for
counting strokes screwing shown in Table 2. Screw in the number of lines shown in Table
(for intermediate values, round to the next section).

fig. 12
Check with the wrench, the calibration, using a shaft keyed to the hollow shaft clutch (fig. 12).
If no match, screwing up the next stretch of obtaining a search value: the table (supplied by
the reducers manufacturer) in fact does not always strictly accurate indications.
Where, by tightening the nut, you get a reduction of calibration, it is necessary to change the
arrangement of springs or increase the number: please contact the Autorotor After-sales dept.
Install the coupling on the gearbox and check the operation of the application.
If the impact remains dynamic, the joint must be loaded more.
This normally indicates a change of loading conditions than the design conditions.
It is appropriate in this case to recheck the size of the unit (contact Autorotor).
The steps below can be performed without removing the coupling from the gearbox (without
checking with a torque wrench), evaluate how the joint application and loading far enough to
determine a movement without shock and vibration upon arrival at the station.
At the end of the calibration, block dial position with the screw and apply a clamping disc
coupling.

It is therefore possible to calculate the
The emergency stop time can be calculated from the balance between the braking action and
the kinetic energy related to the table and motor inertia (passive phenomena are not taken
into account).

5 HANDLING AND TRASPORTATION
Since T10 and T15 weigh less than 25 Kg., they can be lifted manually.
The powered versions and the types weighing more must be lifted by means of lifting eyebolts
to be locked in the suitable holes (pict. 2, pict. 14, and table 3) in accordance with what stated
by UNI ISO 3266 regulation.

6 ASSEMBLY AND INSTALLATION
The rotary index table must be only installed in one of the positions indicated in pict. 3, that is
on fastening supports suitably designed so as to bear the load and to absorb vibrations and
noise. The fastening must be performed through screws the type of which is described in table
3.
The tooling plates must be designed and manufactured according to the technical features of
the table and must fullfill the minimum safety and health requirements stated in the machines
guideline.
To be transported, the table must be crated with the reducer mounted along its side. If the
desired operating position is different, you must unscrew the gear box’s adaptation flange to
the table (be careful of not shacking the motoreducer), rotate the reducer to the desired
position and then rescrew the flange to the table casing. See the table’s serial number on the
first page of this handbook to learn the electrical data.
6.1 Motion transmission to the unit
Should the rotary index table be supplied without gearbox and motor, to have it run well you
must
•consider the output torque of the reducer with reference to the data declared by the
supplier. It must be less by
• 35% for cam angles ranging from 180° to 330°
• 65% for cam angles ranging from 90° to 150°
• check the maximum torque
• be sure of reduced backlash between the screws and the gear of the reducer
• consider a further reduction factor of the useful torque (K=1.3) for transmission
through chains, joints, pulleys, bevel gears etc.
•pinions and pulleys must have the largest possible pitch diameter compatible with
the overall needed dimensions; chains and belts must be inextensible, joints must
be free of backlash.
As a consequence of what written above on the dynamic shock in case of stop during the
table’s displacement time, it is highly recommended to use a torque limiter, to avoid stresses
which can bend and break the cam followers’ pin.
The torque limiter is to be set at a torque value no more than 15% higher than the normally
used torque.

Rotary Index Tables T Series – Translation of manual for use and warnings
6.2 Backlash on transmission
The transmissions rigidity is crucial to the good operating of the table. Check that there are no
slacks between motor shaft and cam holder shaft. If any, by taking them away the pristine
efficiency of the table is regained.
7 PUTTING INTO OPERATION
Before putting the rotary table into operation you must:
• clean it carefully, by taking away dust and any foreign and smudging substance
• clear the rust inhibitor from the parts that are not painted
• adjust the position and operating of the position sensing device, if it is there, which
stops the motor during the dwell position of the table
check the right working of all protection and safety systems of the machine which
incorporates the rotary index table
8 LUBRIFICATION
Autorotor units are lubricated with longlife grease. Accessories, too, (reducers, speed
variators, etc.) are adequately lubricated when supplied already assembled on the units.
The grease quantity in each unit depends on the operating position (pict. 3) and is shown in
table 5.
The lubricant quantity is checked through the level plugs. If you need any detail on lubricant
quantities to be used in operating positions different from those as yet reported, please call the
Autorotor Technical Dept.
Only for units operating at over 150 cycles/minute it is recommended a check on lubricant
level every 2000 hours and lubricant replacement every 4000 hours.
9 MAJOR OVERHAULING
Major overhauling is carried out at Autorotor workshop; please call after-sale service.
9.1 Spare parts
In case of order for spare parts, please let us know the unit type and serial number (they are
shown in the table plate) and the spare part number (see technical data sheets).
10 DISPOSAL OF HARMFUL SUBSTANCES AND DISMANTLING
The table does not release any oil or grease in the environment. Should it be dismantled,
lubricants must be disposed of in accordance with the laws currently in force.
11 NOISE PRODUCED BY THE TABLE
The weighed steady sound pressure level of the rotary index table is less than 70 db (a).

Rotary Index Tables T Series – Translation of manual for use and warnings
note 1: ATTENTION: as to the tables with customized applications (tooling plate, turret,
etc...), it is necessary to mark the position of the application with respect to the the
table output disk, of the output disk and the cam with respect to the casing before
taking them away. While assembling them again, it is absolutely necessary to keep
the pristine phasing between cam, disk and application.
note 2: the cam followers are determined by the table serial number, that must be made
known to Autorotor in order to allow the required spare parts to be sent immediately.
Before replacing pins and cam followers you must check the holes, where the pins are
forced. If the pins are bent or broken there must have occured a dynamic shock
exceeding the highest carriable torque. It follows that the holes may result ovalized on
the lower side of the output disk. Ovalization must be eliminated carefully, restoring
the hole roundness. The diameter of the new pins to be used must be higher than the
original pins’ to make sure that these pins are forced into the holes.

♦ a cam follower’s
pin is broken
a) remove the flanges No.11 by unscrewing the screws
No.15
b) screw a ring nut (for instance No.19)
c) check how it works; the rotation of the cam in touch with
the cam followers must be smooth. If it is not, unscrew
the ring nut No.19 thus restoring the previous
conditions. Repeat the same operation on the ring nut
No.12. The shaft rotation must be slighty forced (preload
on the taper roller bearings No.22 and 23)
d) take away the front plate No.2 by removing the screws
No.14. Before doing that the table must be emptied of
the lubricant. This action can be avoided if the
maintenance is made with the table tilted at 45° (the
side of the table from which the front plate No.2 has
been removed resulting therefore positioned higher than
the opposite side). Thus the lubricant flows into the back
part of the table and may be kept inside the table during
the maintenance.
e) screw the ring nut No.20
f) check how it works: the rotation of the cam in touch with
the cam followers must be smooth
g) clean the contact surfaces of the front plate No.2 and the
casing No.1. Apply a small quantity of fluid sealant and
then reassemble and lock by the screws No.14.
h) pour the lubricant again into the table if the table has
been emptied
i) take away the table output disk by removing the screws
No.13. Remove it through threaded pullers acting on the
threaded holes near the fixing pins (see note 1 on
page 17). Check in the meanwhile that the seal strip of
the bearing doesn’t stick to the casing and
consenquently is damaged
j) clean carefully the surface of the disk and of the casing
k) replace pins and cam followers: remove the nut No.7 and
pull out the pin forced into the hole (see note 2 on
page 17)
l) mount the output disk and check how it works. Remove
it again
m)execute point g) and h)
n) coat the surface of the disk No.3 which is housed in the
casing with flange sealant (loctite 510 for die-cast
surfaces) and mount the disk once more
point.
p) replace pins and cam followers as described in the a.m.
