All of our gearheads have been tested to verify the superi-
or ratings the Gator Series Gearheads produce. Our
advantages stem from engineering expertise in material
selection, precision machine quality, service, and cost. We
do not believe you can find a better planetary gearhead on
the market today. Compare the backlash, torque, and
speed ratings between our planetary and any competitor,
then call us for pricing and delivery. When you make these
fair comparisons, you’ll find that Minarik Gator Series
Gearheads produce an unfair advantage.
oday’s high energy motors can produce large
torques while operating at high speeds. At
times, this can put a mechanical strain or create res-
olution problems on all the devices that are trying to
utilize this power. Minarik’s Gator Series Gearheads
are the solutions to link your motor to these demand-
ing applications. This true planetary gearhead can
reduce your speed while multiplying the torque output
to properly harness all of your motor’s power.
Planetary gearheads take the speed and torque
developed at the motor’s output shaft pinion (sun
gear) and effectively divides it into three orbiting plan-
etary gears. These planet gears react off of two dif-
ferent gear engagements; the rotating sun gear on
one side and the stationary ring gear that surrounds
the entire assembly on the other side. The number of
teeth on the sun, planet, and ring gears determine the
ratio of how much the speed will be reduced and how
much gain will result in output torque.
The ring gear engagement forces the planet gears to
rotate in relative motion to the sun gear. This power,
which had earlier been dispersed to three planet
gears, is now collectively harnessed back through the
planet gear bearing journals into a carrier plate
which in turn drives a subsequent stage or your out-
put shaft. Although it may sound simple in theory, the
details of proper design segregate one manufacturer
from another.
Most planetary gearheads take advantage of the gear
load sharing nature inherent in a planetary design
which reduces concentrated tooth loading and maxi-
mizes torque capabilities. They symmetrically balance
all gear engagements so no radial loading results.
Low backlash and high efficiency are also common
characteristics of this design. The advantages of
Minarik’s Gator Series planetary gearheads goes
beyond these common characteristics.
