2. MaxTorque Worm Gears – Your Sub Sea Advantage
MANUAL, REMOTE OR ROV
Smaller
Gear design allows for greater torque capability in smaller packages
Direct mount allows for reduced head height
70% base efficiency allows the use of smaller actuators or hand wheels
Faster
Close times 50%+ faster close times
50% + fewer turns with the same or less input
Lighter
Smaller gear and actuator = less weight
Direct mount capability may eliminate bulky adaptors

Max tooth contact 2.96
Tooth contact of 6.6 – 10.7
MaxTorque’s gears:
Multi-start = Faster Close
Greater tooth contact / Double enveloping shape = Higher torque capability and significantly less backlash
Novel tooth shape and high contact ratio = low contact / bending stress leading to superior durability
High helix angle = Superior efficiency (70% +)
