Constant velocity joint with control mechanism

摘要

According to one embodiment, a constant velocity (CV) joint includes a first yoke, a second yoke, and a control mechanism. The first yoke is configured to be rotatably coupled to an input device about a first axis and configured to receive the input device through a first opening. The second yoke is rotatably coupled to the first yoke about a second axis and rotatably coupled to an output device about a third axis. The control mechanism is adapted to constrain the first yoke and the second yoke so as to achieve a substantially CV characteristic between the input device and the output device.

1. A rotorcraft, comprising:
a body; a power train coupled to the body and comprising a power source and a drive shaft coupled to the power source; a hub; a rotor blade coupled to the hub; and a constant velocity (CV) joint coupled between the drive shaft and the hub, the CV joint comprising:
a first yoke rotatably coupled to the drive shaft about a first axis and configured to receive the drive shaft through a first opening;a second yoke rotatably coupled to the first yoke about a second axis and rotatably coupled to the hub about a third axis; anda control mechanism adapted to constrain the first yoke and the second yoke so as to achieve a substantially CV characteristic between the drive shaft and the hub, the control mechanism comprising a positioning portion adapted to position the first and second yokes such that the second axis substantially resides on a bisector of an angle between the drive shaft and the hub.
