WPGear - A mechanical gear unit

The technology is based on the existing and well-established principles of Tooth Geometry for gear designs. The gear ratio of the new drive can be fixed or variable (with multiple gears). In addition, its decreased size and mass resulting from the power distribution coupled with the gear unit’s disc, and tube-type designs eliminate installation problems that are a constraint for conventional gear systems. This advantage offers immense possibilities with good efficiency, small mass, increased reliability and load capacity while requiring minimal maintenance. The WPG gear is designed to increase the product's lifetime and achieve maximum power density.

The over 100 concepts described in the PCT patent application and their combinations allow a practically limitless number of possible designs based on the patent protecting the principle. Accordingly, the numbe r of application areas is also limitless.

Current development status: Working prototypes

Advantages:

WPGear has the same load capacity as the cyclo drives but, due to its internal power distribution and innovative concept it has the advantage of:

• higher power density

• large gear ratio (up to 1:1,500,000)

• can be used as a reductor or multiplicator

• compact structural design

• limitless installation possibilities, some hitherto impossible

• high mechanical efficiency

• reliable and precision designs

• “unbreakable” designs possible

• higher torsional stiffness

• low noise level

• low propensity to overheating

• self-locking possible

• zero backlash drive possible

• accurate positioning

• coaxial design

• shock load capacity of up to 500%

Potential application:

• Robotics industry

• Food industry

• Medical industry

• Mining industry

• Oil industry

• Energy industry (wind, hydropower, nuclear, etc.)

• Automotive industry

Market:

WPGear is currently the only drive on the market allowing direct integration into an electric motor and the use multiple gears if needed, and may even replace frequency converters in certain applications. While existing harmonic drives and cyclo drives can only be used as reductors, the WPGear can be used as a reductor or a multiplicator.
