8 Minimum Design Speed Considerations for Sleevoil Bearings for Industrial Fan Applications (September 2016)

Slow speed operation of fan systems within the air handling industry is generally performed due to two reasons: a coast down operation is required for hot (induced draft) fans to cool down before shutdown (often by using a turning gear), and operational efficiency improvements can be achieved during non-peak periods by slow speed operation using a VFD. In either case, when these fans are supported by hydrodynamic bearings, it is the oil film thickness developed from the bearing-shaft interaction that limits the minimum speed that can be maintained without causing premature wear and bearing failure. This paper will present a brief overview of lubrication theory and critical design parameters to achieve slow speed operation.

23 Lightweight, Highly Efficient Drive System (February 2017)

This paper presents a joint project conducted by Ashwoods Electric Motors and Oerlikon Fairfield that uses planetary drives with an integrated electric motor. Current solutions used in production of off-highway vehicles rely upon large, heavy and inefficient brushed DC or induction motors, coupled to a planetary gearbox. This presents a number of challenges to the vehicle designers such as: limited vehicle range, limited space around the motor/drivetrain, and motor durability. The proposed integrated system utilizes an Oerlikon Fairfield Torque Hub, widely used in off-highway vehicles, and the Ashwoods first-to-market, interior permanent magnet motor. How these products are integrated, i.e. incorporating a brake solution, represents a market-changing product. Using interior permanent magnet (IPM) technology in the motor design means the motor can be up to 70% lighter, 70% smaller and 20% more efficient than traditional motors used in off-highway traction applications.

The first space shuttle flight was that of the Space Shuttle Columbia (OV-102), launched April 12, 1981. The disaster that destroyed Columbia occurred on its 28th flight, February 1, 2003, nearly 22 years after its first launch.

31 Development of an Actuator for Ambient to Cryo Application (December 2010)

During the qualification campaign of the NIRSpec (near-infrared spectrometer) instrument mechanism, the actuator could not achieve the expected lifetime that had been extended during the development phase. The initial design could not be adapted to the requested number of revolutions during that phase. Consequently the actuator needed to be modified so that the function of the mechanism would not be endangered or, by extension, the overall function of the NIRSpec instrument. The modification included a change of the overall actuator design—internal dimensions, tolerances, materials, lubrication and assembly process—while keeping the interface to the mechanism, mass and function.
