The traditional pin-cycloid planetary drive has a series of essential advantages such as small volume, light weight, wide range of speed ratio, high efficiency, and quiet operating as well. On the other hand, it has a natural weak point that the tumbler bearing, which supports the cycloidal gear on the arm is placed inside the cycloidal gear, therefore the size of the bearing is restricted due to the geometry of the gear.

Because of the fact, the bearing capacity of the whole drive cannot be developed well enough. To improve the performances of the load-capacity, transmission efficiency, and reliability of mechanical drive, we originally developed some designs of the double crank ring-plate-type cycloid planetary drive. The new-type drive keeps all the natural advantages, which is of multi-tooth mesh, small mesh angle, and hardened tooth flank of gears. Moreover, The drive does not need the special output unit as the ring-plate-type drive does, so that the rigidity of the output shaft becomes much higher. Since the tumbler bearing is placed outside the cycloidal gear, the size of the bearing is no longer restricted to any extent.
