MaxTorque Worm Gears – Your Sub Sea Advantage

All images and concepts are property of MaxTorque, LLC

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% +)
