Dual-Cam Bellcrank Mechanism

摘要

A method and system for imparting a linear motion to a flexible shaft is disclosed. The system includes a bellcrank having a first arm, a second arm, and a first pivot pin therebetween. The system further includes an actuating device coupled to the first arm and configured to apply a force to cause the bellcrank to rotate about the first pivot pin. Still further, the system includes a second pivot pin coupled to a rod-end of the flexible shaft and further coupled to a slotted hole on the second arm. Yet still further, the system includes a follower surface on the rod-end of the flexible shaft and configured to slide on a cam surface machined on the second arm. Upon application of the force to the first arm, the flexible shaft moves in a substantially linear motion.

1. A system for imparting a linear motion to a flexible shaft, the system comprising:
a bellcrank having a first arm, a second arm, and a first pivot pin therebetween; an actuating device coupled to the first arm and configured to apply a force thereto to cause the bellcrank to rotate about the first pivot pin; a second pivot pin coupled to a rod-end of the flexible shaft and further coupled to a slotted hole on the second arm; a follower surface on the rod-end of the flexible shaft and configured to slide on a cam surface machined on the second arm; and wherein upon application of the force to the first arm, the flexible shaft moves in a substantially linear motion.
