Rethinking how mechanical power moves
HOGENAR IGT (Infinity Gear Transmission) is a mechanical transmission architecture designed to transfer torque through controlled rolling contact — reducing sliding friction at the primary power-transfer interface.
Continuous variation. Controlled rolling contact. One mechanical platform
Power transmission sits at the heart of transportation, energy, industrial machinery, robotics and countless drive systems. Conventional solutions perform remarkably well, but sliding contact, auxiliary systems and multi-component architectures can introduce energy losses, wear and maintenance demands.
IGT approaches the problem from a different direction. Its geometry is designed to combine continuous ratio variation with a controlled rolling-contact power path — creating new possibilities for efficient torque transfer and integrated drivetrain functions.
A different approach to variable transmission
IGT is a mechanical transmission platform based on a proprietary geometric and kinematic principle. It is designed to adjust the transmission ratio continuously while maintaining torque transfer.
Unlike architectures that depend on a friction-driven traction interface, IGT is designed around controlled rolling contact between precision kinematic elements. This is intended to reduce sliding losses at the main power-transfer interface and support a more integrated drivetrain architecture.
Designed for value across the system lifecycle
Efficiency potential
Reducing sliding at the primary torque-transfer interface can limit frictional losses and heat generation, subject to configuration and operating conditions.
Durability potential
A rolling-contact architecture is intended to reduce wear at the main power-transfer interface and support longer service intervals.
Simpler drivetrain integration
Where several transmission functions can be combined in one application-specific configuration, IGT may reduce the number of separate mechanisms and interfaces.
Lower lifecycle demands
Measured efficiency, fewer wear-intensive interfaces and reduced component count can contribute to lower maintenance, downtime and total cost of ownership.
One platform. Multiple sectors
Any rotating system that must transfer torque, change ratio or control motion may present an opportunity for IGT. The most promising applications will be selected through joint engineering and validation.

A new architecture for continuously variable power transmission
Infinity Gear Transmission (IGT) uses a proprietary geometric and kinematic principle to continuously vary the transmission ratio while transferring torque through controlled rolling contact.

Why transmission architecture matters
Mechanical power-transmission systems balance torque capacity, ratio range, efficiency, durability, control and package size. Conventional architectures solve these requirements through proven combinations of gears, clutches, friction-driven variable transmissions, hydraulics and electronic control.
Those solutions are highly effective in the applications for which they are designed. They can also require trade-offs: sliding losses, lubrication systems, multiple discrete mechanisms or additional control hardware. IGT is being developed to offer a different balance of those requirements.
Controlled rolling contact at the power-transfer interface
IGT transfers torque through geometric interaction between precision kinematic elements. The contact geometry is designed to maintain a controlled rolling relationship as the transmission ratio changes.
This architecture is intended to reduce sliding in the primary power path while enabling smooth, continuous ratio variation. Detailed geometry, load paths and control methods remain confidential and are shared with qualified partners under appropriate agreements.
Engineering characteristics of the platform
Continuous ratio variation
The transmission ratio is designed to change smoothly, without the discrete steps of a fixed-ratio gear set.
Torque transfer during ratio change
The architecture is designed to maintain the mechanical power path as the ratio changes, enabling uninterrupted torque transfer.
Reduced sliding in the primary power path
Controlled rolling contact is intended to limit the sliding losses and heat associated with friction-driven traction interfaces.
Application-specific integration
In selected configurations, IGT may integrate functions that otherwise require separate mechanisms, including direction control, braking behavior, differential action or precision positioning.
Dry-running options
Some configurations are intended to operate without a conventional oil-lubricated traction interface. Lubrication requirements for bearings and auxiliary components remain design-specific.
Scalable configuration
The platform is intended to be adapted to different torque, speed, packaging and environmental requirements through application-specific engineering.
Not a conventional gear set. Not a friction CVT. Not a hydraulic drive
A fixed-ratio gear train uses meshing teeth and usually changes ratio through discrete gear stages. A friction-driven CVT varies ratio continuously through a traction interface. A hydraulic drive transfers and controls power through pressurized fluid. IGT is a distinct mechanical architecture designed to combine continuous ratio variation with a controlled rolling-contact power path.

Frequently asked questions
Does IGT eliminate friction?
No mechanical system is completely frictionless. IGT is designed to reduce sliding at the primary torque-transfer interface by using controlled rolling contact. Bearings, seals and other supporting components may still produce frictional losses.
How is IGT different from a conventional CVT?
Both are intended to provide continuous ratio variation, but their torque-transfer principles differ. Conventional friction-driven CVTs rely on traction between contacting surfaces. IGT is designed around geometric rolling interaction between precision elements. Application-level testing is required to compare torque capacity, efficiency, durability and control behavior.
How does IGT compare with Varionova’s RatioZero (“Zero Rotation”) concept?
Both pursue continuous ratio variation. As publicly described, RatioZero passes torque between planets through one-way clutches, which in our assessment limits it to drives that need no braking, reversing or back-driving. IGT is designed to vary speed and transmit torque through continuous rolling contact, without using clutches of any kind.
How does IGT compare with an eCVT?
An eCVT sets the ratio through an electric machine on a planetary gearset, so it needs a second, independently controlled power source beside the engine (typically motor-generators, a battery and an inverter). That adds conversion losses, cost and dependence on electronics. IGT is purely mechanical and needs no second power source.
Can IGT operate without lubrication?
Selected IGT configurations are designed for a dry primary torque-transfer interface. Lubrication requirements for bearings, seals and auxiliary components depend on the final system design and operating environment.
Can one IGT configuration replace a clutch, brake or differential?
Certain configurations may integrate functions such as engagement behavior, braking, direction control or differential action. The available functions and performance limits must be defined and validated for each application.
Is IGT available as an off-the-shelf product?
IGT is currently positioned as a technology platform for application-specific development and licensing rather than a single catalogue product.
Why are detailed drawings not published?
The operating geometry contains proprietary and potentially reproducible know-how. Qualified partners can receive additional technical information at the appropriate stage of discussion and under suitable confidentiality agreements.
What is the collaboration process?
The process normally begins with an application discussion and high-level technical assessment. If there is a credible fit, the next stages may include a confidentiality agreement, detailed engineering review, feasibility work, prototyping, validation and licensing negotiations.
What comes next for the technology?
Development priorities include application-specific prototypes, industrial validation, manufacturing readiness and expansion of intellectual-property protection in selected markets.
