<p><P>PROBLEM TO BE SOLVED: To smoothly oscillatingly rotate external gears even if a strong radial or thrust load is applied from a load side thereto. <P>SOLUTION: In this eccentrically oscillating speed reducer 110, the external gears 118A, 118B are eccentrically oscillated by eccentric bodies 116A, 116B mounted on an eccentric shaft 114. The eccentrically oscillating speed reducer comprises a pair of first and second carriers 124A, 124B connected to each other through inner pins (connection bodies) 126 extending through the external gears 118A, 118B. Carrier support surfaces 125A, 125B positioned at right angle to the axes of the first and second carriers 124A, 124B are formed on parts of the first and second carriers, respectively. Eccentric shaft support surfaces 117A, 117B positioned at right angle to the axes of the eccentric shaft 114 are formed on parts of the eccentric body shaft, respectively. The first and second carriers 124A, 124B and the eccentric shaft 114 are supported by thrust plates 128A, 128B, 134A, 134B disposed on the carrier support surfaces 125A, 125B and the eccentric shaft support surfaces 117A, 117B, respectively. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
