PROPELLER BLADE RETENTION DEVICE |
摘要 |
A propeller blade retention system and method of manufacture are disclosed. Because of the design, a truly integral hub is able to house a set of variable pitch blades. Each hub socket establishes a substantially cylindrical interface with its respective blade, making the blade slidably receivable for installation. Each blade is allowed axial rotation, and held inside the socket by a set of angular contact bearings. A snap ring locks the blade against coming back out of the socket. An O-ring is provided in the interface to create a fluid seal. The hub alone accomplishes all of the required load-bearing and weather-seal functions. |
