Abstract: A speed increasing bidirectional mechanical converter, including a main shaft and a speed increasing planet gear unit is disclosed. The speed increasing planet gear unit includes a first ring gear, a planet gear, a sun gear and a planet carrier, wherein the planet gear is mounted on the planet carrier. The planet gear is arranged between the first ring gear and the sun gear, and rotates in an opposite direction against the sun gear. The speed increasing bidirectional mechanical converter further includes a reversing means, via which the first ring gear and the sun gear drive the main shaft. When in use, the planet carrier is kept still, and the main shaft rotates in the preset direction. The speed increasing bidirectional mechanical converter realizes the direction reverse by using the speed increasing planet gear unit, which simplifies the structure, facilitates the manufacture and decreases the space it occupies and its weight.

Abstract: The present invention discloses a bidirectional mechanical converting unit, comprising: a main shaft; a driving mechanism, which including a driving means and a reversing means which are coupled to each other; and a rotation means for inputting torque, an rotation axis of the rotation means being coaxial with the main shaft, the rotation means and the driving mechanism being coupled to each other, and the driving mechanism delivering the torque to output at the main shall at a predetermined direction, no matter in which direction the rotation means rotates; wherein the predetermined direction can be switched via the reversing means. The present invention is simple structured, not only can efficiently utilizes the movements of the rotation means in either way, but also can switch the rotation direction of the output shaft conveniently upon demand, with easy operations.
