Gear drives are fundamental in most processing operations, connecting the prime mover to the driven equipment and ensuring that the system has enough torque to effectively move product. Correctly specifying and selecting the proper gear drives for critical applications leads to reliability, greater uptime, and profitability.
Back in 1913, in Ann Arbor, MI., Leander J. Hoover founded the Hoover Steel Ball Company. In 1990, Tsubaki Nakashima company of Japan acquired the US ball manufacturing company and is currently the biggest manufacturer and supplier of precision balls in the world. Its first markets were the growing automotive and precision bearing industries. More than a century later, the electric vehicles (EV) market is becoming more and more relevant, though the combustible auto industry continues to grow. Its market for high-quality precision products has extended to medical, aerospace, military defense, and critical applications. After the great age of steel, a new era opened wide spaces for more extreme materials which paved the way for ceramics.
GWJ Technology GmbH has presented a new version of its desktop solution TBK with numerous enhancements, particularly in the field of gearing. The TBK calculation software has been used successfully worldwide for more than four decades to dimension gears, shafts, connections, bearings, and other machine elements as well as complete gearboxes. With its various interfaces to 3D CAD systems, the TBK software is a powerful calculation tool for development, design, work planning, production, and quality assurance.
NSK Ltd. has released a new gas turbine generator bearing for eVTOLs including large drones, which is expected to extend drone flight range. The new product was used for the gas turbine generator of a large drone (high payload emergency supply delivery drone equipped with a gas turbine generator) equipped with an 80-kw hybrid drive system for a regional reconstruction and practical development promotion project in fiscal 2023 and delivered to Fukushima Prefecture on February 21, 2024.
Spline rumble is characterized by a multiple low shaft order droning noise. It arises in electrified vehicle (EV) powertrains due to excitation at the spline connection between the motor rotor and the transmission input. It is caused by the interactions between manufacturing errors. In this article SMT will be looking at how MASTA can be used to predict rumble in a modern EV gearbox with a three-bearing input assembly layout.
OHLAs provide both overhung radial and axial load support to protect electrified mobile equipment motors from heavy application loads, extending the lifetime of the motor and alleviating the cost of downtime both from maintenance costs and loss of production. OHLAs also provide a contamination barrier to protect the electrified system from harsh environments that may include water, dirt, abrasives, chemicals, and other invasive debris, which are often present in mobile equipment applications.
Genuine Parts Company, a global distributor of automotive and industrial replacement parts, has announced that its board of directors has appointed James F. Howe to the position of president, Motion, the company's industrial business, effective April 1, 2024. With nearly three decades of dedicated service to the company, Howe brings a wealth of experience and expertise to his new role.
SKF has developed a novel solution to an emerging problem in electric vehicle (EV) powertrain design. The SKF Conductive brush ring provides a reliable electrical connection between an EV eAxle rotor shaft and its housing, which increases eAxle lifetime expectations. When used in combination with SKF Hybrid ceramic ball bearings, it helps to even further alleviate parasitic current effects that can lead to premature failure in bearings and other components.
