Abstract
A turbomachine defining a radial direction and an axial direction, the turbomachine including: a structural assembly comprising a frame and a static structure; a gearbox coupled to the structural assembly through the static structure; a turbine coupled to the gearbox and having a plurality of turbine rotor blades spaced apart from one another in the axial direction, each of the turbine rotor blades extending in the radial direction; and a thrust bearing disposed in a load path from the turbine to the static structure, the load path extending through the gearbox to transmit axial loads from the turbine to the static structure.

A turbomachine defining a radial direction and an axial direction, the turbomachine comprising:
- a structural assembly comprising a frame and a static structure;
- a gearbox coupled to the structural assembly through the static structure;
- a turbine coupled to the gearbox and having a plurality of turbine rotor blades spaced apart from one another in the axial direction, each of the turbine rotor blades extending in the radial direction;
- and
- a thrust bearing disposed in a load path from the turbine to the static structure, the load path extending through the gearbox to transmit axial loads from the turbine to the static structure.
A turbine section for a turbomachine defining an axial direction and a radial direction, the turbine section comprising:
- a gearbox;
- a turbine coupled to the gearbox and having a plurality of turbine rotor blades spaced apart from one another in the axial direction, each of the turbine rotor blades extending in the radial direction;
- and
- a thrust bearing configured to be disposed in a load path from the turbine to a static structure of the turbomachine, the load path extending through the gearbox to transmit axial loads from the turbine to the static structure.
A vaneless counter-rotating turbine (VCRT) turbomachine defining a radial direction and an axial direction, the turbomachine comprising:
- a gearbox coupled to a static structure of the turbomachine;
- a turbine coupled to the gearbox, the turbine comprising:
- a low-speed turbine including a first plurality of turbine rotor blades spaced apart from one another in the axial direction and extending radially from a rotatable drum;
- and
- a high-speed turbine including a second plurality of turbine rotor blades spaced apart from one another in the axial direction and extending radially from a rotatable drum, wherein each turbine rotor blade of the second plurality of turbine rotor blades is spaced apart in the axial direction by at least one turbine rotor blade of the first plurality or turbine rotor blades;
- and
- a thrust bearing disposed between the static structure and the drum of the high-speed turbine, the thrust bearing being configured to transmit axial loads from the high-speed turbine to the static structure.
