摘要： PROBLEM TO BE SOLVED: To perform high precision detection of positions on the output side of a planetary differential type speed reduction gear, improve the accuracy of feedback control, prevent the increasing cost of a device, and eliminate the limitation of rated torque of the device due to the ambient temperature. SOLUTION: A control device of a planetary differential type speed-reduction gear controls the driving force of a motor 10 by means of a control means 20, reduces the speed of the motor by the planetary differential type speed- reduction gear 1 to transmit the reduced driving force to the output side of the speed-reduction gear 1, and performs specified operations by the output side driving force. In this case, the motor and planetary differential type speed reduction gear are connected by a cylindrical shaft 21, and a shaft 22 connected to the output side of the planetary differential type speed-reduction gear penetrates through the cylindrical shaft 21 into the opposite side of the speed reduction gear with respect to the motor. An output rotary detecting device 23 is provided at the tip of the penetrating shaft 22, and the control device controls the driving force of the motor 10 based on the information of the output rotary detecting device 23 to perform prescribed operations.

摘要： PROBLEM TO BE SOLVED: To realize the high speed, non-maintenance, and high performance of this device by composing the device of a pin, for straddlingly supporting a circular arc tooth profile internal gear, and a rolling bearing to be fitted into the pin; and engaging a bearing outer ring with an epitrochoid tooth form external tooth gear. SOLUTION: A crank pin 31, for creating the rotational movement of two pinions 33, is rotatably supported at both the ends between bearings 27 and 29, and has crank parts 31a and 31c decentered to the rotation axial line ACD of the pin 31. The pinions 33 have epitrochoid tooth form external teeth on the outer peripheral surface, and equip a pin hole 33b engaging with the crank part 31a or 31c via a bearing 35. The pinions 33 loosely fit to the columnar part 21 of a supporting block 13, and the center axial lines of the crank parts 31a and 31c revolutionarily move to the rotation axial line of the pin 31 by the rotational movement of the pin 31 to decenteredly and revolutionarily move two pinions 33, thereby engaging the external tooth with the outer ring of a rolling bearing 9 supported by the pin of a hub 37. This constitution realizes the high speed, no maintenance, and high performance of a motion control device.
