Abstract
A dual rotary cam may include a first rotating unit, a second rotating unit, a first rod, a second rod and a transmission device. The transmission device has an active gear, two connecting gears, and two passive gears. The active gear is driven by a motor to drive the connecting gears. A decelerating gear that is co-axially disposed with the connecting gear is used to connect the passive gears. The passive gears co-axially connect with the connecting portions of the first rod and second rod. The gear motion between the active gear, connecting gears, passive gears and decelerating gear can be arranged to adjust the gaps therebetween to achieve a goal of seamless transmission of the rotary cam.
