The present invention relates to a decelerator of a concrete mixer truck. In particular, the present invention relates to a decelerator which includes a mixer drum and a cover flange for supporting the mixer drum to make the center thereof located at the rear of a decelerator, and to have high performance with respect to weight, shock, output, and a load. According to an embodiment of the present invention, the decelerator of a concrete mixer truck comprises: a decelerator housing; a planetary gear train accommodated in the decelerator housing, and configured to transmit power; a gear flange having a first tooth shape formed on the outer circumference thereof so as to be engaged with the planetary gear train; an output shaft having an end connected to the gear flange, and including a plurality of keys cut in an axial direction; an internal gear having a spline formed on the inner circumference thereof to be fitted into the keys of the output shaft to be able to perform a slip motion, and having a second tooth shape formed on the outer circumference thereof; and a cover flange having a third tooth shape formed in a hollow inner circumference so as to be engaged with the internal gear, and having a frame formed in a predetermined thickness to support the mixer drum in a circumferential direction.

    본 발명은 콘크리트 타설용 믹서 트럭의 감속기에 대한 것으로서, 특히 믹서드럼과 상기 믹서드럼을 지지하는 커버플렌지를 포함한 경전 중심이 감속기 후방에 위치하도록 형성하여 하중, 충격, 출력, 부하에 강한 성능을 갖도록 하는 감속기에 대한 발명이다. 본 발명의 일 실시예에 따르면, 콘크리트 믹서 트럭의 감속기에 있어서, 감속기 하우징; 상기 감속기 하우징에 수용되며 동력을 전달하도록 마련된 유성기어트레인; 상기 유성기어트레인과 치합되도록 외주연에 제1치형이 형성된 기어 플렌지; 단부가 상기 기어 플렌지와 연결되며 축방향으로 복수 개의 키(key)가 절삭된 출력 샤프트; 내주연에는 상기 출력 샤프트의 키(key)에 끼워져 슬립운동이 가능하도록 스플라인이 형성되고, 외주연에는 제2치형이 형성되는 내접기어; 및 상기 내접기어와 치합되도록 중공의 내주연에는 제3치형이 형성되고 원주방향으로는 믹서 드럼을 지지하도록 소정 두께의 프레임이 형성된 커버 플렌지를 포함하는 콘크리트 믹서 트럭의 감속기를 제공한다.
