Abstract
A planet gear drive mounting in the carrier of a speed increasing planetary gear train for driving a diesel engine turbocharger or the like includes a supporting axle carrying an enlarged hub which engages and supports a bearing in the gear, the gear being lightened and the bearing area being enlarged by the large inner diameter of the bearing (preferably at least 50 percent greater than that of the axle) so that centrifugal force caused bearing loads are reduced and bearing loadings are minimized. Lubrication and other features are also disclosed.
