Abstract
PURPOSE: To reduce noise and vibration, by using an elastically deformable bearing for a shaft coupling between an external gear and driven shaft of a cycloidal reduction gear.
CONSTITUTION: A cycloidal reduction gear has a set of internal and external gears 17, 13, both being inscribed to each other for engagement. The revolution of external gear 13 which is eccentric to the fixed internal gear 17 and driven by a driving shaft 6 is transmitted inversely to a driven shaft 20. In this case, transmission pins 15 are fitted to the external gear 13, and a bearing 19 made of elastic material with an inner diameter nearly equal to [diameter of transmission pin 15+2× (osculating circle's radius of internal gear 17 - osculating circle's radius of external gear 13)] is fixed to a position opposed to the transmission pin 15 of a coupling 18 fixed to the driven shaft 20, and this transmission pin 15 is engaged with the said bearing 19.
