The CTI Symposium, home of the worlds international Transmission and Drive Community returns to Shanghai, 23rd-25th September 2019. #CTI-SYM

CTI China, part of the CTI world series, provides the most comprehensive agenda and specialist exhibition for those seeking the latest information on developments in automotive transmissions and drives for passenger cars and commercial vehicles. This year will be focused on Automotive Drivetrains, Intelligent, Electrified.

Orbitless is pleased to be presenting a technical paper titled, ‘Developing a low-NVH Orbitless EV primary reduction drive.

As a new high efficiency low NVH, topology for gearboxes and powertrains for a variety of applications, Orbitless offers the opportunity for OEMs and Tier1 eDrive programs to address key issues that the industry as a whole is looking to improve.

This presentation outlines the eDrive Project that was developed under an international Eureka! Program @EUREKA_NETWORK, in cooperation with the @NRC_CNRC program in Canada and InnovateUK in the UK. Orbitless has partnered with @RomaxTechnologies, a leader in geared electrification modeling and simulation software and services and @LinamarCorp, a leader in Gear and Gearbox manufacturing to virtually model, simulate and produce an eDrive prototype able to withstand the demanding operational requirements of an automotive eDrive.

The goal of the project is to compare the relative benefits of an Orbitless drive to a traditional Planetary drive as it relates to benefits for NVH ( Noise, Vibration and Harshness), Efficiency, Lubrication and High Speed Input support. This project further validates the work that Orbitless has done in smaller form factors for other markets like robotics, medical devices or home automation solutions.

This talk covers the unique design considerations in developing an Orbitless drive including managing its unique geometry, which removes the standard ring gear and replaces it with an offset carrier. It also discusses the ability to use standard off the shelf bearings, seals and gears and how it will be tested on a dynamometer providing 16,000+ rpm input speed. Results will show the low TE, NVH and high efficiency results achieved in the virtual phase of the project.
