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
Multi-Start, Double Enveloping Worm Gear Set, 4140 HT Standard
Bronze/Ductile Iron Composite
360° Worm Wheel
Sub-Sea Advantages
- 200%+ more efficient
- 50%+ fewer turns with less rim pull / input torque
- Proprietary Self Locking Design
- Superior Sealing; O-rings or lip seals at all junctions
- Unique sealing system for shallow applications to prevent organic intrusion.
-Compensation to 3,000 M

How We Do It: Double Enveloping Worm Gear
Max tooth contact 2.96
Double Enveloping Worm GearMulti-
Start
Single Start
Tooth contact of 6.6 – 10.7
Standard Gears MaxTorque
Single Enveloping Worm Gear
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% +)
