Abstract
The invention relates to a press fitting tool for a front bearing and a rear bearing of a stern tube, and belongs to the technical field of ship repairing and building. The press fitting tool sequentially comprises a screw rod (1). The screw rod (1) is sequentially provided with a first screw rod nut (2), a hollow jack (3), a first spherical gasket set (4), a stern bearing pressing plate (5), a stern bearing seat (6), a front bearing seat (7), a front bearing pressing plate (8), a second spherical gasket combination (9) and a second screw rod nut (10) from left to right in a sleeved mode. The cylinder body end of the hollow jack (3) is fixedly connected with the screw rod (1), and the piston rod end of the hollow jack (3) abuts against the first spherical gasket set (4). The press fitting tool for the front bearing and the rear bearing of the stern tube is simple in structure and convenient to operate, improves the press fitting efficiency of the front bearing and the rear bearing of the stern tube, and lowers the labor intensity of workers.
