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.
