Summary:PURPOSE: An integrated deceleration device for an auger screw of a crane is provided to obtain strong force for rotating an auger screw at a low price by integrating a hydraulic pump and a deceleration device in a single body. CONSTITUTION: An integrated deceleration device for an auger screw of a crane comprises a pump-integrated decelerator, a connection cover(31), a bracket, and a screw deceleration device(30). The connection cover is coupled to a hole of the pump-integrated decelerator by a cover fixing bolt. The connection cover forms connection protrusions(32) connected to a joint by a connection shaft(27). The connection cover comprises a cover flange(33). The bracket is installed in one side of an inner case covering the exterior of the decelerator. The bracket has a screw connection shaft, an inclined bearing, and a grease injecting hole. The screw deceleration device supports the inclined bearing coupled to the screw connection shaft. The screw deceleration device connects an outer case(42) for supporting the inclined bearing.
