 Direct
Drive High-Torque vs. Planetary Grinders

Comparison
between Direct Drive Gears & Planetary Gearbox ---
in relation to energy consumption, maintenance,
performance.
- ENERGY CONSUMPTION
--- EFFICIENCY.
- Planetary,
belt-driven gearbox
- Direct Drive Gears
- Helical-Cut, Metal Gears: maximizes power, torque and energy effectiveness while minimizing
amp draw and friction loss.
 MAINTENANCE
--- CASE-HARDEN STEEL GEARS.
Built like the
transmission in a car, providing decades of life and uninterrupted
service with less maintenance vs. a belt-drive gearbox.
- Drive
belts will wear and snapped at the most unfortunate times.
Realistically, case-harden steel gears are far superior than
a fiber belt.
- Not only do direct drive
gears provide the advantage of driving the
diamond plate with minimal power loss and amp draw, but
zero maintenance and breakdowns are virtually assured.
- PERFORMANCE ---
WEIGHT &
POWER.
- Direct Drive:
- The basic design of direct drive gears provides the highest
production rate in its class
- Majority
of the grinder's weight is where it matters most, which is the grinding
head
- More power, more
effective use of the power, and greater grinding pressure is
delivered using less weight.
- How powerful
and effective is a direct drive, high-torque grinder? Rubber
coatings are effectively removed vs. a belt-driven grinder whose
belts will slip and/or break (especially notched belts.)
- Planetary Gearbox:
Relies on belts to provide higher RPM,
but lower torque:
- Ideal for polishing
applications
- Effectiveness in grinding and
coating removal is significantly diminished
- Amp
draw is three times greater than a direct drive grinder.
- CONCLUSION: Direct
drive gears exhibit compelling advantages over a planetary gearbox in
terms of energy efficiency, reduced amp draw
and virtually zero maintenance requirements. While a belt-driven
planetary gearbox excels in high RPM and low-torque scenarios (i.e.
polishing), its
performance in grinding and coating removal falls short and its amp draw
is substantially higher.
I trust that this
information will assist you in making an informed decision regarding the
appropriate gear system for your specific needs. Should you have
any further questions or require additional clarification, please do not
