AUMA INDIA GEAR OPERATORS
Gear Boxes combine with
Actuators to complete the valve control
service. There are basically three types of Gear
Boxes, namely Worm Gear Boxes (GS & GF Series),
Bevel Gear Boxes (GK Series) and Spur Gear Boxes
(GST Series).
All Gear Boxes are manufactured to comply with
auma Germany specifications. The housings are
designed for high rigidity to absorb high
torsional and thrust loads. The Gear Box
enclosure conforms to IP 67 class. IP 68 enclosures
can also be supplied on request. All Gear Boxes are
lubricated with special grease for life.
auma
india
The Gear Boxes are designed for output torque
from 300 Nm (GS 40) to 250,000 Nm (GS 500) for
motor operation. The main features of GS Gear
Boxes are:
- Full 360 worm wheel design, making the GearBox suitable either for multiturn or quarter turn
operation.
O
- A separate coupling with involute splines is
provided for coupling to the valve. The
coupling is removable for machining the bore
to suit valve shaft. The orientation of the GearBox while mounting on valve is made simple
due to involute splines on the coupling.
- Unique design of end stoppers on input shaft
with screws and nut mechanism allows precise
and positive setting upto 135 operation.O
- Each Gear Box is designed for use with
Actuator to facilitate economical
automation of valves.
auma
india
- To reduce the input torque, for a given output of
Worm Gear Box, a primary reduction Gear
Box can be easily attached at input of the Gear
Boxes. For this purpose, GS 100 & GS 125
Gear Boxes are fitted with planetary reduction
Gear Box (VZ4) and higher series are fitted
with Spur Reduction Gear Boxes (GZ) of
various ratios. This feature enables selection
of smaller actuators for economical sizing.
In case of quarter turn operation, additional three
segments are available for repositioning, thus
extending the life of worm wheel by three times.
auma india GS type Gear Boxes are designed for
rotation upto 135 with end stop or 360operation of Ball Valves, Butterfly Valves, PlugValves, Dampers etc. The extremely ruggedconstruction features positive adjustable end stopon input shaft for precise valve positioning.

BEVEL GEAR BOXESTYPE GK 10-GK 35
SPUR GEAR BOXESTYPE GST 12 - GST 1600
GF Series of Gear Boxes are specially used for
actuation of Dampers and Fly Valves which
require quarter turn applications.
GK bevel Gear Boxes are available for wide
range of torque and thrust load capacity ranging
from 120 Nm torque x 60 KN thrust (GK 10) to
8000 Nm torque x 820 KN thrust (GK 35).
Various types of output drives (Type A to Type E) are
available, depending upon application.
GK Gear Boxes are designed considering poweroperation and are easily adapted
Actuators, thus enabling small actuators to be
economically sized for operation of large valves.

india
The gear operator is a worm Gear Box of GSSeries with a built-in floor stand and a cranklever. The crank lever is provided with a number ofmounting ball and socket joints at varyingmoment arms to suit given damper/valveapplication. All other features of GF series aresame as GS Gear Boxes. GF Gear Boxes in sizeshigher than GF 250 can be supplied on request.
auma india Bevel Gear Boxes are designed tooperate all types of rising or non-rising stemvalves and gate valves where thrust may or maynot be taken by the Gear Box. The bore of the
output bevel gear allows valve stem to passthrough it to reach its full travel.
GF Series Gear Boxes can also be coupled to
primary reduction Gear Boxes and alsoActuators to obtain ON-OFF Control or
regulating duty.

GST range of spur Gear Boxes are
designed for operation of rotating stem valves.
They can be combined with
Actuators or can be easily operated by handwheels. GST Gear Boxes can be easily adapted
for Globe, Angle and Non return valves. They
produce an output torque of 120 Nm (GST 12)
to 16000 Nm (GST 1600).

Output torque for manual operation
Output torque for motor operation
Input torque at max. output torque
Input torque at nominal output torque
Mechanical advantage
OTums for 90
Suitable actuator (with output drive type E) Type
Max. permissible weight of actuator
OOperating time in sec. for 90 at actuator speedOperating times shorter than indicated (13-17 sec)only after consultation with factory
OFor rare operation, based on a service life of min. 2000 cycles of 90O
Nominal torque for frequent operation, based on a service life of min 15000 operating cycles of 90
Conversion factor output torque to input torque
Recommendation, based on an usual manual effort for most of the travel and a permissible higher force in order to fully close or break open the valve
The operating times mentioned are approximate for service at 50 Hz, at 60 Hz the speeds increase by 20% and the operating times reduce to 83% of the stated values

LINEAR OR MULTI TURN VALVES(Eg : GATE, GLOBE DIAPHRAGM TYPE ETC.)
For output thrust upto 190kN and output torque upto100 kgm, multiturn actuators can be directlyselected and mounted on the valve. However,also offers bevel gear boxes type ''GK'' and spur gear
boxes type ''GST'' for upto and higher torque/thrustrequirements.
aumaa
Choose the nearest available actuator output speed(refer Actuator catalogue for details) i.e. 125rpm.
auma
Where actuator designation SA50E125 indicatesopen-close duty actuator SA50 with output drive typeE having output rpm of 125
After selecting the suitable model, the following pointsshould be verified:
1. Output torque capacity (refer ''Technical Data'' fordetails).
2. Max. stem acceptance dia. (refer ''Technical Data''and ''Output Drive'' for details).
3. Mounting flange compatibility (refer ''TechnicalData'' and ''Output Drive'' for details).
Note: When coupling actuator with gearbox, always employ output drive type 'E'.

Referring to the ''Technical Data'' of Gear Boxcatalogue (GK10-35), suitable actuator model givenin the table is to be selected.
The required output rpm of the actuator can becalculated as follows:
For rising stem valves, always select output drive'type A'
Select gear box type whose max. thrust permissibleis more than or equal to required thrust.
In this case, gear box type is GK25.1, whosemaximum thrust permissible is 320kN.

PART TURN VALVES: (Eg: BUTTERFLYVALVES, BALL VALVES, PLUG VALVES,LOUVRE DAMPERS ETC.)
In part turn valves, the final movement of valve shaftO
required is normally 90 . The electrical actuators are primarily multi-turn type and hence, it is necessary toemploy an intermediate worm gear box between the
O
actuator and the valve so as to achieve 90 angle ofrotation.
auma offers the following two types of worm gear boxes:
*Note: In case of regulating/modulating service, max.(or unseating) torque and regulating (orrunning) torque are required for proper
selection. Regulating torque should not exceed50 % of max. torque.

Step 2 : Sele ction of Actuat or
Refer ''Technical Data'' of gear box catalogue(GS 40 - GS 125 & GS 160 - GS 500)
Referring to the ''Technical Data'' of Gear Boxcatalogue, suitable multi-turn actuator (given in the
bottom row) is to be selected.
Please note that economical sizing of actuator can bedone by using higher reduction ratios consideringoperating time requirement. This is achieved byemploying a primary reduction gear box havingdifferent ratios.
Refer to the bottom-most row in the ''Technical Data''O
for different operating time in seconds for 90 atdifferent actuator output speed.
Select a gear box type whose ''Output torque formotor operation'' is more than or equal to required''valve torque''
In this case, gear box type is GS 160 whose maximumtorque capacity for motor operation is 8000Nm
Data required:
Minimum data:
Direct flange mounting type ''GS''
Foot mounting type ''GF''
In this case, three options are available for selection:
Option 1 : Referring to first column of ''TechnicalData'' of GS 160.Model : GS 160 with SA50E32 actuator.
OOperating time = 25 secs. (for 90 )Actuator designation SA50E32 indicatesopen-close duty actuator SA50 with output
drive type E, having output speed of 32.
Option 2 : Referring to second column of GS 160.Model : GS 160 + GZ 14 (216:1) withSA 12E125 actuator.

Where GZ 14 in the primary reduction gear box and 216:1 is the total reduction ratio ofthe gear box.
After selecting the suitable model, following important points should be checked:
Out of the above three options, any one suitablecombination can be selected, considering the operatingtime.
1. Max. stem/shaft dia. (refer ''Technical Data'' fordetails).
