Planetary Drive Principle

Planetary Drive Principle

 
The gearbox is driven with the help of a center shaft, connected to a carrier plate carrying three smaller gear wheels. These gear wheels run inside a toothed outer ring and drive the central gear cut around the central output shaft. This leads to the load being divided among many contact points around each gear, thus ensuring less friction and finally an increased efficiency.

The Planetary gearing configuration of a Sun Gear and three more Planets does offer exciting new design engineering possibilities, borne of its ability to deliver high torque capacities, high reduction ratios and efficiency in a compact modular package.

The planet wheels in these gearboxes are generally set 120 degrees apart, leading to 'load equilibrium' and thus resulting in a balanced or 'zero force' within the geared components. This further results in very low wear and high shock loading capacity.

Another advantage of the planetary gearbox arrangement is load distribution. Because the load being
transmitted is shared between multiple planets, torque capability is greatly increased. The more planets in the
system, the greater load ability and the higher the torque density.

LUBRICATION

 

Planetary Gear Boxes are suitable for Oil Temp between -20° to 90° C. Lower than-20°C OR above 90° C, we recommend special Oils and Oil Seals.
Lubricant recommended for Indian ambient temperatures of 40° is Gear Oil, EP220 (ISO VG 220) ISO 3448. For High Speed and Power applications contact Factory. Oil change must be carried out after first 100/ 150 hours operation and subsequently after every 2500 hours or at least 12 months. These conditions may be modified depending upon the actual working condition.
Do not mix oils of different types even of same make. Never mix synthetic and mineral oils

A )     Output Torque Calculation :-
 

          Output Torque      =            (7124 x HP x SF x Eff.)
               (Nm)                                 Output Speed

 
            1) HP = Power in Horsepower
            2)  SF = Service Factor
            3) Eff. = Drive Efficiency
                 Planetary drive Efficiency - Single Stage - 96%              Triple Stage - 88%
                                                         Double Stage - 92%             Four Stage - 85%
 
 
B )     Output Speed Calculation :-
 

         Output Speed        =             Input Speed (RPM)
                (RPM)                               Reduction Ratio

 
 
 C )    Service Factor Selection :-
 
  • Working Hours & Application
    a) 8 Hours -1.3
    b) 16 Hours - 1.7
    c) 24 Hours - 2.0
 
 
D )    Power Conversion :-
 
          Power in Kw (1 H.P.=0.746 Kw)
          Power in H.P. (1 k.w.=1.34 H.P.)
