きる。2. Description of the Related Art An eccentric oscillating type speed reducer is also called a planetary gear speed reducer. For example, a speed reducer disclosed in Japanese Patent Publication No. 39-25398 transmits rotation of a driving shaft to two eccentric shafts and an output shaft. The input rotation of the eccentric body shaft is converted into the output rotation of the internal gear by meshing with the internal gear connected to the internal gear and swinging the external gear having a smaller number of teeth than the internal gear. On this occasion,
If the internal gear is fixed and the external gear can be rotated, the input rotation of the eccentric shaft can be converted to the output rotation of the external gear.

り結果として装置が大きくなる問題がある。As described in Japanese Patent Application Laid-Open No. Sho 59-106744, the structure of such an eccentric oscillating type speed reducer is such that an eccentric body shaft connected to an input shaft is connected to an oscillating rotation center of an external gear. And the input rotation of the eccentric shaft is transmitted to the output shaft via an inner pin by the rotation of a rotatable external gear that meshes with the fixed internal gear. This type has a problem that the output torque is limited because the torque is transmitted by the cantilevered inner pin, and the output torque does not increase because the number of the inner pins contributing to the torque transmission is about half. In order to increase the size, it is necessary to increase the size of the inner pin.

Two eccentric gears are equidistantly arranged around the two external gears (120 degrees apart), each eccentric shaft is supported at both ends, and the rotation of the input shaft is controlled by the rotation of the eccentric shaft. The swing motion is converted to the output rotation of the internal gear. In this device, the eccentric body shaft is supported at both ends, the external gear is driven by the plurality of eccentric body shafts, and the torque is transmitted at the same time, so that a large and small torque can be output.

One eccentric shaft is connected to the input shaft, and the other eccentric shaft is a driven eccentric shaft that can move freely by disconnecting from the input shaft, and is used as a transmission shaft that transmits only the rotation of the external gear. Devices have also been proposed.

There was a problem that required. In the case of an eccentric body shaft having a plurality of eccentric bodies having different phases fitted to a plurality of external gears having different swing phases, in addition to machining the shaft (rotating shaft), the eccentric bodies having different phases are different. Need to be processed separately, which requires many steps.
