Roller Mils are directly driven bevel-wheel planetary gears or bevel cylindrical gear units. The gear unit represents an almost integral component of the mill. The output flange of the gear unit is rigidly connected with the grinding table. In addition to transmitting the torque ,the gear unit also has capability to take up the reaction forces from the the griding force of the mil’s rollers.

Hydro dynamically or hydrostatically lubricated thrust bearing being mounted in the upper housing parts of the gear unit absorb the grinding force which is then transferred though the housing into mill’s foundation .

This growing number of roller mills in operation as well as the increasing specific need and demand of gear transmission feature.

Product Details:

MountingFoot, flange
OrientationHorizontal , vertical
Power (HP)40 to 460 kw

Elecon Bucket wheel planetary gear units are available in various sizes ranging from 40 to 460 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.

Product Details:

Size1.5 kw
reduction ratio400 to 1000
TypeBevel-helical

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.

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.
