Ultra Planetary Gearbox

Dynatech’s special reduction gearbox employs helical gears to reduce drive motor speed to required speed. They can be broadly classified into two categories.

Ultra Planetary Gearbox	Horizontal Multi Train Gearbox
Gearbox input and output shafts are vertical	Gearbox input and output shafts are horizontal
Drive motor - Either foot mounted, flanged type or directly coupled	Drive Motor - Convenient to use foot mounted drive motor

Advantages

• Dynatech’s Special Reduction Gearboxes employ helical gears that have a transmission efficiency of 98% as the power transmission is by line or multi point contact.
• Further helical gear by its very nature can take reverse shock.
• The gears are heavy duty, heavy torque and made of special steels which have a longer shelf life.
• Specialized design that facilitates saving of power up to 80% under ideal conditions.
• Single or multi stage gear trains are available, with which wide range of output speeds can be obtained.
• Specific required ratios can be easily designed.
• Initial power requirement is low.
• Compact body of carbon steel takes care of impeller loads as well as shock loads.
