| PLANETARY
GEAR MOTOR |
 |
Working
Principle |
| A large family gear
arrangements are under the general name of Epicyclic gearing. Generally
speaking the Epicyclic train has a central 'sun' gear with several planets.
The name Epicyclic comes from the fact that points on the planets trace
out epicycloidal curves in space. The name planetary is used interchangeably
with epicyclic to denote the whole family of gears. |
| In order
to cover the wide range of reduction ratios and power handling, various
methods of planetary gear arrangements, which include simple Planetary Trains,
compound Planetary Trains or Coupled Planetary Trains may be employed.

| Salient
Features |
| High
Efficiency |
| The planetary
gears with high degree of rolling transmission, accurately positioned with
friction free bearing ensures high values of efficiency. |
| Versatile
Reduction Ratios |
| Reduction
Ratios as indicated in the selection chart are intended for standard applications
which are in line with general market practices, Intermediate ratios or
higher ratios can be offered to suit the application requirements. |
| Low
Interia |
| Due to
low inertia. Planetary gearboxes demand less accelerating torque and improve
machine response when used with High Response electronically controlled
variable speed drives. |
| Reversible
Transmission |
| This feature
makes Planetary gears ideal for high inertia loads where sudden stoppages
will result in transmission of torque and speed in reverse direction. The
reversibility allows this power to be transmitted to the high speed end
of the gear box without causing any damage to the gears, couplings or other
elements in the line of power transmission. |
| Compactness
and high Load Carrying capability |
| The power
transmitting capacity of Planetary gear systems is higher than standard
gearboxes and hence they are able to transmit greater power for a given
size. |
| Co-Linear
Shafts |
| Input and
output shafts are Co-Linear and may be coupled with prime mover and driven
machine by various standard connecting methods such as direct coupling,
chains, belts etc. |
| Minimal
Maintenance |
| Maintenance
is limited to topping up of oil level in the gearbox, external cleaning
and changing of bearings as per preventive maintenance schedule. |
| Quality
Gears |
| High quality
alloy steel gears are heat treated and ground as necessary. |
