A bearing assembly for a gear pump that includes a bearing housing, a bearing, and a biasing member. The bearing housing has a housing bore that extends between a first housing end and a second housing end along a bearing axis. The bearing is disposed within the housing bore. The bearing has an outer diameter extending between a first bearing end and a second bearing end. The biasing member is disposed between the bearing and the bearing housing to apply a biasing load to the bearing.

A connection for a rotating machine according to an exemplary aspect of the present disclosure includes an interface axially between and adjacent to a first interference fit and a second interference fit.

Interface with mount features for precise alignment

An permanent magnet alternator stator assembly for an integrated air turbine starter and permanent magnet alternator assembly has a permanent magnet alternator stator winding assembly attached to a mounting structure. A quick electrical connector electrically connects to the stator winding assembly and is attached to the mounting structure. The mounting structure includes an alignment aperture for removably attaching the permanent magnet alternator winding assembly to an air turbine starter. An integrated air turbine starter and permanent magnet alternator assembly and accessory gearbox assembly are also described.

Integrated gas turbine engine accessories

A mechanical system has a component to be lubricated that requires greater lubrication at lower speed conditions than would be required at higher speed conditions. A lubricant tower is biased to a position allowing a greater flow of lubrication to the component at lower speed conditions, then moved to a position at higher speed conditions where there is a lesser flow of lubrication.

Lubrication cut-off at high speed

A brake assembly () for an air turbine starter () includes a brake cylinder () located in the air turbine starter (). A brake piston () is located at least partially within the brake cylinder () and slidable therein. A biasing member () biases the brake piston () toward a turbine wheel () of the air turbine starter () applying a braking force to the turbine wheel () and defining a piston chamber () between the turbine wheel () and the brake piston (). A through opening () in the brake piston () into the piston chamber () is configured such that a flow of fluid through the through opening () into the piston chamber () applies a force to the brake piston () sufficient to overcome the bias thereby allowing rotation of the turbine wheel ().
