Planetary Gearboxes have much higher mechanical rating compared to parallel shaft Gearbox as the power being transmitted gets equally distributed among three to five streams in each stage thus reducing the induced stresses which very much optimizes the size as well allows to accommodate higher ratio to eliminate open pair.
The reduction in floor space as compared to conventional drive i.e with open gearing, almost to the tune of 50% reduction in floor space.
Heaviest gear internal such as annuli are stationary thus requires no bearing and automatically improves the stability and reduces the Vibration level and in turn noise. Low noise level of 80-85 db as well as low vibration level going up to 4.5 mm/sec can be achieved.
Direct drive eliminating open gears, bearings for same, coupling in between secondary gearbox and Open gearing – thus saving 5 to 6 % power consumption. For example, for a 45×90 Mill for power 1100 kW which also includes the drive power of TRPF/GRPF we can get a saving which is approximately equivalent to 20% of the additional expenditure for drive-part i.e. within five seasons additional expenditure is recovered and sugar starts earning additional Profit due to this solution.
Planetary Gearbox have an advantage that the planet bearings are only loaded where as in case of Bearings supporting Sun or Carrier loads are more or less nullified by virtue of higher no of planets and their equal and opposite forces.
Lubrication of planetary gearbox is quite simple as the rotating gear train partially act as pump thus allowing splash lubrication.
We are proposing three-to five stage planetary gearbox in each stage Sun is input and carrier is the output keeping annuli stationary as well acting as casing and supported on saddle as shown in Drawing.
Elecon's machine capability cuts the internal teeth of annulus to the accuracy of DIN 7 or Grinds if required to the accuracy class DIN 6.

Elecon Bucket wheel planetary gear units are available in various sizes ranging from 25 to 375 kw and reduction ratio ranging from 140 to 480.
These gear units are especially designed for bucket wheel drive of stacker-reclaimer machines.
The gear unit consists of Four to Five reduction stages comprising of bevel, helical and planetary being a last pair in the system.
The gear units are available in hollow shaft design with Shrink Disc and have a integral drive frame for mounting electric motor and brake, with necessary fork for fixing the torque arm.
The sun, planet and helical wheels are case hardened and ground to quality 6 as per DIN 3961-63. The annulus is made up of high tensile alloy steel, heat treated or nitrided depending upon power requirement. The spiral bevel gears having cyclopalloid tooth from are case hardened and lapped in pairs so as to ensure optimum tooth contact pattern during assembly.
The casing is of welded construction mainly in two parts made out of Fe 410 WA IS 2062. The bearing bores are machined with high degree of accuracy on CNC machines.
Elecon slewing gear units of planetary as well as bevel-helical type (conventional) are available in various sizes ranging from 1.5 kW and reduction ratio ranging from 400 to 1000.
These gear units are especially designed for the slewing mechanism of the stacker-reclaimer machines.
The planetary gear units normally have four-stage reductions out of which the first stage is designed as helical or bevel pair, and the remaining stages according to planetary gear systems.
The conventional gear unit consists of five to six reduction stages comprising bevel and helical gear pairs.
The sun and planet gears are case-hardened and ground to quality 6 as per DIN 3961/63. The annulus is made up of high tensile alloy steel, heat treated or nitrated depending upon power requirement. The spiral bevel gears in case of conventional gear units are case-hardened and lapped in pair so as to ensure optimum tooth contact pattern during assembly. The casing is of welded construction mainly in three parts in case of planetary gear unit and in two parts in case of conventional gear unit. The bearing bores are machined with high degree of accuracy on CNC machines.

Heavy Duty Stirrer unit incorporates an extended bearing housing to accommodate a larger bottom bearing and increased shaft size, there by enhancing the unit capacity to absorb the high bending loads imposed during stirrer applications. This gear unit is compact with facility of top mounted pivoted platform where electricmotor can be directly mounted above the gear unit using belt tensioning device.
Cooling Tower Fan Drive Gear Unit incorporates an extended top bearing housing to accommodate the larger wheel shaft bearing.
Length of the output shaft extension are manufactured to client's requirements and to suit fan hub mounting.
Lubriction is entirely contained by splash and lower bearing dip in the oil bath while oil is pumped to the top wheel shaft bearing by mean of a built in plunger mechanism. All exposed parts other than the extensions are applied with corrossion resistant paint.

Elecon engineering has expertise in designing and manufacturing high speed, high power gear boxes.
TA – Turbo Gear Unit (Double Helical Gear)
The TA TURBO Gear unit is a single stage step-up or reduction Gear unit with horizontally offset. It is designed as a double helical Gear unit.
High Gearing quality and tooth flank modification adapted to actual tooth load allow for extremely high pitch line velocity.
Double helical Gear units are simple to design & manufacture and compact. Double helical gearboxes are more efficient than single helical gear boxes.
This Gear unit is used in high speed plants such as turbo generators, turbo Compressor, Boiler feed pump application etc.
