PROPELLER SHAFT ASSEMBLY FOR AIRCRAFT ENGINE - A simplified explanation of the abstract
This abstract first appeared for US patent application 17932748 titled 'PROPELLER SHAFT ASSEMBLY FOR AIRCRAFT ENGINE
Simplified Explanation
The propeller shaft assembly for an aircraft engine described in the abstract includes a shaft with a bore extending through it at the front end. The shaft has a front flange with a base merging with the outer surface of the shaft. A sleeve is coupled to the shaft within the bore by an interference fit, with at least part of the sleeve axially aligned with the front flange. The sleeve extends from a front to a rear sleeve end, with the rear sleeve end axially offset from the engine side surface of the front flange at the base.
- Shaft with bore extending through the front end
- Front flange with base merging with outer surface
- Sleeve coupled to shaft within bore by interference fit
- Sleeve axially aligned with front flange
- Sleeve extends from front to rear sleeve end
- Rear sleeve end axially offset from engine side surface of front flange
Potential Applications
This technology could be applied in aircraft engines, propeller systems, and other rotating machinery where precise alignment and secure coupling of components are crucial.
Problems Solved
This innovation solves the problem of ensuring a secure coupling between the shaft and sleeve within the bore, preventing slippage or misalignment during operation.
Benefits
The benefits of this technology include improved reliability, reduced maintenance requirements, and enhanced performance due to the precise alignment of components.
Potential Commercial Applications
Potential commercial applications of this technology include aircraft manufacturing, aerospace engineering, and industrial machinery production.
Possible Prior Art
One possible prior art for this technology could be similar propeller shaft assemblies used in other types of machinery or vehicles, such as marine propulsion systems or automotive drivetrains.
Unanswered Questions
How does the interference fit between the sleeve and shaft affect the overall performance of the propeller shaft assembly?
The interference fit ensures a tight connection between the sleeve and shaft, but how does this impact the efficiency and durability of the assembly in real-world applications?
What materials are typically used for the shaft, front flange, and sleeve in propeller shaft assemblies for aircraft engines?
The choice of materials can significantly affect the performance and longevity of the assembly, so understanding the common materials used in similar applications is crucial for optimizing the design.
Original Abstract Submitted
A propeller shaft assembly for an aircraft engine includes a shaft having a bore extending through the shaft at a front end thereof, the front end of the shaft having an outer surface facing radially outwardly from the shaft and an inner surface spaced apart from the outer surface and facing radially inwardly to the bore. The shaft has a front flange extending radially outwardly on the outer surface, the front flange having a base merging with the outer surface of the shaft. A sleeve is coupled to the shaft within the bore by an interference fit between the sleeve and the shaft, at least part of the sleeve axially aligned with the front flange. The sleeve axially extends from a front to a rear sleeve end, the rear sleeve end axially offset from the engine side surface of the front flange at the base of the front flange.
