Dismounting device for radial floating stern tube bearing

The invention discloses a dismounting device for a radial floating stern tube bearing. The dismounting device comprises a stern tube, a bearing, a butt joint column, a sliding limit assembly and a floating adjusting assembly. According to the dismounting device, the floating adjusting assembly is additionally arranged, and the outer ends of short connecting rods are each slidably sleeved with a limit abutting wedge block; the inner sides of the outer ends of limiting plates are each vertically and slidably sleeved with a clamping rod, and therefore a sliding structure that the limit abutting wedge blocks and the limiting plates radially float on the outer sides of the short connecting rods and the clamping rods is formed; in this way, through rotation of a radial adjusting screw rod, the limiting plates and the limit abutting wedge-shaped blocks are driven to float radially, and therefore the limit abutting wedge-shaped blocks are adjusted axially and radially, and can be adjusted according to the size of a b
