Problems solved by technology
Generally, the structure of the bearing pad of the gearbox has a great influence on the safe use of the gearbox. The traditional gearbox bearing pad adopts an integral structure. For the application field of large gearboxes, the bearing pad of the overall structure is not reliable. Once damaged, the gearbox must be disassembled for maintenance. It is not conducive to maintenance, the maintenance time is long, the cost is high, and the delay to normal work is relatively large

The invention relates to a combined bearing bush device of a large gear box, which is arranged between a bottom plate of the gear box and a push force head of an output shaft of the gear box. The bearing bush device comprises a screw cover, a radial push force bush, a bush bearing seat, an upper axial push force bush and a lower axial push force bush, wherein the radial push force bush is sleeved outside the cylinder part of the push force head and is radially fixed through the bearing bush seat, the bottom of the bearing bush seat is fixed on the bottom plate through a bolt, the top of the bearing bush seat is fixedly connected with the screw cover for pressing the radial push force bush, the upper end face of the disk part of the push force head is provided with the upper axial push force bush, the upper axial push force bush is fixed on the bearing bush seat, the lower end face of the disk part of the push force head is pressed on the bottom plate through the lower axial push force bush, the lower axial push force bush is fixed on the bottom plate; and the screw cover, the radial pushing force bush, the bearing bush seat, the upper axial push force bush and the lower axial push force bush are in a multi-block combined structure. The combined bearing bush device has the advantages of compact structure, safety in use, convenience for installation and maintenance, low cost and the like.
Description
technical field [0001] The invention relates to a large gear box, in particular to a combined bearing bush device for a large gear box used in the fields of a nuclear power water circulation cooling pump transmission device, a hydroelectric power generation speed increaser box, and the like. Background technique [0002] The transmission device of nuclear power water circulation cooling pump usually adopts vertical planetary gear transmission, and the motor is located at the top of the whole equipment. Water thrust, gearbox structure must be designed to be safe and reliable. Generally, the structure of the bearing pad of the gearbox has a great influence on the safe use of the gearbox. The traditional gearbox bearing pad adopts an integral structure. For the application field of large gearboxes, the bearing pad of the overall structure is not reliable. Once damaged, the gearbox must be disassembled for maintenance. It is not conducive to maintenance, the maintenance tim...
