Oscillating internal meshing type rotational speed reduction gear for conveying rotary motion with variable gear ratio, has external toothed gear and internal toothed gear, with which external toothed gear is engaged from inside

摘要

The rotational speed reduction gear has an external toothed gear and an internal toothed gear (14), with which the external toothed gear is engaged from the inside. Multiple eccentric body shafts have eccentric body for moving the external toothed gear. Two supporting bodies are provided in axial direction on two sides of the external toothed gear. The supporting bodies support eccentric body shafts at both ends in rotary manner, where multiple support pins are provided.
