The present invention has simple structure, standard parts, easy manufacture, and low production cost.

Description

technical field [0001] The invention relates to a device belonging to the technical field of mechanical transmission, in particular to a pivotal gear box. Background technique [0002] Pivot gearboxes are specially used on cutter suction, bucket wheel or blower suction dredging vessels. These types of dredgers have a slot in the front half of the hull, and a bridge frame is placed in the slot. Equipment such as underwater mud pumps and cutter heads are installed on the bridge frame. The bridge frame can rotate around two left and right bearings placed on the hull to change the dredging depth. The submersible mud pumps on the bridge are directly driven by a deck-mounted diesel engine through a bridge-mounted pivot gearbox. Since the shaft driving the submersible mud pump needs to follow the bridge to rotate at any practical angle, the pivot gearbox must be installed between the left and right bearings of the bridge.

AI Technical Summary

Problems solved by technology

Since dredgers often work in harsh sea conditions, the hull will move, and the pivotal gearbox will follow the movement of the hull. At the same time, since the pivotal gearboxes are all installed on the bridge frame, the bridge frame must often rotate according to construction requirements. Therefore During dredger construction operations, the pivoting gearbox will generate very complex movements

For the pivotal gearbox in complex motion, due to the deformation of the hull during use, insufficient rigidity of the bridge, the concentricity of the pivot of the gearbox and the shaft of the bridge, and the lateral movement of the bridge, etc., the pivotal gearbox will be caused.
