PURPOSE: A gear bearing is provided to reduce the number of rotation elements and remove a retainer, thereby simplifying the structure and reducing the assembling time and a reject rate. CONSTITUTION: A gear bearing includes an outer orbit wheel(1) formed with protruded inner diameter surface and an inner orbit wheel(2) formed with a protruded outer diameter surface, and rotation elements(3) each having an outer diameter surface protruded to be engaged with the inner diameter surface of the outer orbit wheel and the outer diameter surface of the inner orbit wheel. |
