The present invention relates to an emergency lubricant oil supply device for a reducing gear, capable of preventing physical damage to a reducing gear by stably supplying lubricant oil to the reducing gear in the event of power shutoff. According to the present invention, the emergency lubricant oil supply device includes: an electric motor interlinking motor which operates when rpm of the reducing gear is less than reference rpm to supply the lubricant oil to an interface between a pinion driving shaft and the reducing gear; a reducing gear interlinking pump which operates when the rpm of the reducing gear is not less than the reference rpm to supply the lubricant oil to the interface between the pinion driving shaft and the reducing gear; and a gravity tank supplying the lubricant oil to the interface between the pinion driving shaft and the reducing gear when the rpm of the reducing gear is less than the reference rpm in a state in which the electric motor interlinking pump is stopped.
본 발명은 전력 차단시 감속기어로의 안정적인 윤활유 공급이 가능하도록 하여 감속기어의 물리적 손상을 방지할 수 있는 감속기어에 대한 비상 윤활유공급장치에 관한 것으로서, 본 발명에 따른 감속기어에 대한 비상 윤활유공급장치는 감속기어 회전수가 기준회전수 미만인 경우에 동작되어, 감속기어와 피니언 구동축의 계면에 윤활유를 공급하는 전기모터 연동펌프와, 감속기어 회전수가 기준회전수 이상인 경우에 동작되어, 감속기어와 피니언 구동축의 계면에 윤활유를 공급하는 감속기어 연동펌프 및 상기 전기모터 연동펌프의 동작이 정지된 상태에서 감속기어 회전수가 기준회전수 미만인 경우에, 감속기어와 피니언 구동축의 계면에 윤활유를 공급하는 중력탱크를 포함하여 이루어지는 것을 특징으로 한다.
