PURPOSE: A power transmission transmits the power of an actuator with a simple power transmission system. CONSTITUTION: A power transmission comprises a pair of cases(52), an actuator(60), the first and the second driving sprockets(64a, 66a), the first and the second axles(68. 70) and the first and the second chain transmissions(64, 66). The cases(52) on both sides have the first and the second working holes(54a, 54b) formed on the front side and the rear side thereof and the third working hole(54c) formed on the middle thereof. The actuator(60) is fixed to the place of the cases(52) corresponding with the third working hole(54c) and has an output shaft(62) protruding into the cases(52). The first and the second driving sprockets(64a, 66a) are fixed on the output shaft(62). The first and the second axles(68, 70) are installed to the places of the cases(52) corresponding with the first and the second working holes(54a, 54b) penetrating through the inside of the cases(52) and have the first and the second driven sprockets(64c, 66c) installed on one ends thereof. The first and the second chain transmissions(54a, 54b) transmit power from the first and the second driving sprockets(64a, 66a) to the first and the second driven sprockets(64c, 66c). |
