COOLING TOWER

PC/RC SERIES

GERABOX

CAT NO. PR01-0612

Premium PC-Series

Features

Premium PC-Series Right angle gear drives in single/double

reduction are intended to satisfy characteristics requirements and

conditions encountered in cooling tower drives. The series

covering models PC114 - PC145 having ratios ranges of 1.66:1 to

4.57:1 in single reduction and PC214 - PC245 having ratio ranges

5.06:1 to 20.9:1 in double reduction are exclusively meant for

cooling tower installations with features like uni-case casting, 3-

point foundation, pump less lubrication, bottom opening for end

float adjustment and combination of Labyrinth double oil seal

arrangements at fan end with double oil seal towards motor ends.

Bevel gears: Spiral bevel gears are manufactured from high

quality case-hardened alloy steels, generated in modern and

sophisticated systems, case hardened and lap finished in pairs.

Helical gears: Helical gears are machined from high quality case

hardened alloy steels, flank ground to precision accuracy grades

for low noise and vibration.

Case hardened surface with softer core provides improved wear

resistance and fatigue strength.

The gear strength is calculated followed by standard ANSI/AGMA

6013-A06.

Case: Grey cast iron casing is of rigid construction with necessary

ribbing reinforcement and design optimized to absorb fan loads

and dampen noise and vibration. They are provided with easily

accessible service ports.

Bearings: Taper / spherical roller bearings from major

manufacturers are used. These bearings are of ample capacity to

meet or exceed minimum life requirement as laid down by Cooling

Technologies Institute (CTI).

Life span of bearing:

Input, Intermediate shaft bearings > 50,000 hours L life10

Output shaft bearings > 100,000 hours L life10

Shafts: High strength case hardening alloy steels are used for

shafting. Direct hardening steel is used for low speed shaft.

Cylindrical seats for bearings, wheel seats, couplings and fan are

finished by precision grinding. These shafts have been designed

to accommodate external loads and fan stresses as appropriate.

Seals: Shaft extensions are fitted with high quality spring loaded

rubber seals to prevent outflow of oil. The ingress of external

contaminants including micro bubbles of water particles are

arrested by employing double oil seals with grease accumulation

in between. In addition, metallic labyrinth seal on low speed shaft

further takes care of the moist atmosphere.

Lubrication: Lubrication of gears and bearings is entirely self

contained by ‘Splash-lubrication’. Built in oil-thrower on the high

speed shaft ensures positive splash at all speeds resulting

continuous circulation of oil to top bearings through built in cast

channels and trays. Recommended lubricants are shown the

Lubricants charts.

Rotation: The drives are designed for high speed shaft rotations

1500 ~ 1750 r/min.

For units operating at input rpm below 750 r/min, Contact

Premium for additional information.

As per standard practice for cooling tower drives both the high and

low speed rotate ‘Clockwise’ when viewed on respective shaft

ends.

Reduction ratio: The allowable deviation of exact (actual) ratio is

± 3%.

Drive shaft: For better performance use of drive shafts made of

Composite / Carbon Fiber between motor and gearbox is

recommended.

Cooling: Standard drives are cooled by normal heat dissipation

through convection / radiation from externally exposed surfaces.

Thermal ratings are equal to or exceeds the service ratings when

the discharge air temperature is 50°C or less. Contact Premium

when the discharge temperature exceeds 50°C.

Accessories: Roller backstop device, provision for vibration

transducers, provision for temperature probe, oil level switch etc.

can be provided on request. Contact Premium for additional

information.

Premium RC-Series

Premium RC-Series Right angle gear drives in single/double reduction are intended to satisfy characteristics requirements and conditions encountered in cooling tower drives.

These are designed as direct replacement for the equivalent models in terms of critical mounting dimensions.

The single and double reduction nominal ratios are maintained exact within 2% of the equivalent models which will eliminate the need for costly fan pitch adjustment after direct replacement.

The catalogue contains specification, dimension and rating for selection of standard gear drives against usual applications.
