Abstract

The invention relates to a central supporting bearing of an external boring machine. The central supporting bearing comprises a bearing shell (1), wherein four pairs of worm and gear mechanisms are uniformly placed on the bearing shell (1) in a circumferential direction; each worm and gear mechanism comprises a flange plate (3) and a Hough flange (4); the flange plates (3) are fixedly connected with the bearing shell (1); the Hough flanges (4) are fixedly connected with the flange plates (3); central frame worm wheels (5) are arranged between the flange plates (3) and the Hough flanges (4); two worm brackets (14) are arranged on one sides of the flange plates (3); a worm (15) is arranged between the two worm brackets (14); and apexes (9) are threaded in the middle of the central frame worm wheels (5). Through the adoption of the central supporting bearing of the external boring machine provided by the invention, dead weight deformation and supporting problems of a boring rod in the shafting boring process are solved, a better use effect is obtained in the shafting boring process, the rigidity of the boring machine is enhanced, the accuracies of form and position of boring are enhanced and the machining quality is guaranteed.

Description

technical field [0001] The invention relates to a central support bearing for an outer boring and boring row, and belongs to the technical field of ship repairing and building. Background technique [0002] In the ship outfield boring process, the stern tube boring of the ship shaft system (main engine, intermediate shaft and stern shaft system) is a relatively complicated and demanding job. The stern tube is closed, unlike boring the rudder system and rudder blades, etc., ordinary auxiliary supports can be added in the middle, so boring the stern tube will lead to poor rigidity of the boring bar, and the boring hole is prone to taper and ovality, which affects the processing quality. Contents of the invention [0003] The object of the present invention is to overcome the above disadvantages and provide a central support bearing for the outer boring row, which solves the problem of poor rigidity of the boring row and improves the precision of the outer boring. [0004] T...
