And produces an ultra-large proportion of torque output.

In this embodiment, the reverse sliding screw drive principle is adopted. The power comes from inside long and narrow circle casing, and moment of torsion must be very big, and according to lever principle, the driving arm is short, and the driven arm is long, and the torsion requirement that the driving arm applyed is very big, and the final working force who obtains of driven arm just can satisfy.
Principle of obtaining large torsion: characteristics of sliding screw drive: the speed reduction transmission ratio is large. The pitch is generally very small, and under the condition of very large rotation angle (rotating speed), very small linear displacement can be obtained, and the transmission chain of the mechanism can be greatly shortened. By applying the principle of sliding screw transmission, we think reversely and design by adopting reverse sliding screw transmission. The basic principle is that a large linear displacement is used to drive a large lead, namely a large pitch, so that a small rotation angle (such as a 90-degree rotation angle) required by the hinge is obtained, and the torque of the small rotation angle is large, which is not achieved by the automatic hinge of the traditional planetary gear reducer. For example: the rotation angle only needs ninety degrees, the slider travel is arranged with 200 millimeters, namely quarter pitch lead, and the pitch of the helical groove reaches 800 millimeters (200 x 4) when the pitch is 360 degrees. The sliding spiral transmission has the characteristic of large speed reduction transmission ratio, if the pitch lead is large, the linear displacement is also large, so that a small corner can be obtained, and the thrust of linear motion can be converted into a very large corner torque.
