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
The present invention relates to a kind of outer boring boring row center support bearing, belong to and build the ship technical field.
Background technology
In the Boring of boats and ships outfield, the stern tube bore hole of marine shafting (main frame, jackshaft and stern tube shaft system) is a more complicated and demanding work, its maximum characteristics are that axis hole length is long, middle by the stern duct occlusion, unlike boring rudder system and rudder blade etc., the centre can add common supplemental support, so the boring stern tube just causes the boring bar poor rigidity, institute's bore hole easily produces tapering and ovality, affects crudy.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, a kind of outer boring boring row center support bearing is provided, it has solved the problem of boring row poor rigidity, has improved outer boring precision.
The object of the present invention is achieved like this: a kind of outer boring boring row center support bearing, it comprises bear box, be provided with the copper bearing in the described bear box, be provided with the iron lining in the described copper bearing, the edge circumferentially has been evenly arranged the fourth officer worm-and-wheel gear on the described bear box, described worm-and-wheel gear comprises ring flange and half flange, described ring flange is fixedly connected with bear box by the first bolt, described half flange is fixedly connected with ring flange by the second bolt, be provided with the centre frame worm gear between described ring flange and the half flange, described ring flange one side is provided with two worm brackets, be provided with worm screw between described two worm brackets, described worm screw and centre frame worm gear are intermeshing, be coated with top in the middle of the described centre frame worm gear, be provided with external screw thread on the described top outer wall, be provided with internal thread on the described centre frame worm gear inwall, described internal thread and external screw thread are intermeshing, also be provided with feather key on the described top outer wall, offer gathering sill on described ring flange and the centre frame worm screw inwall, described feather key is installed in the gathering sill.
Be provided with copper sheathing between described worm screw and the worm bracket.
Compared with prior art, the present invention has following beneficial effect:
A kind of outer boring boring row center support bearing of the present invention, it has solved boring bar deformation induced by gravity support problem in the boring for shafting process, and result of use is better in the boring for shafting process, has improved the rigidity of boring row, improve the accuracy of form and position of Boring, guaranteed crudy.

The specific embodiment
Referring to Fig. 1 ~ Fig. 3, a kind of outer boring boring row center support bearing of the present invention, it comprises bear box 1, be provided with copper bearing 2 in the described bear box 1, be provided with iron lining 11 in the described copper bearing 2, described iron lining 11 is set on the outer boring boring bar 12, be connected by positioning key 13 between described iron lining 11 and the outer boring boring bar 12, circumferentially be evenly arranged the fourth officer worm-and-wheel gear on the described bear box 1, described worm-and-wheel gear comprises ring flange 3 and half flange 4, described ring flange 3 is fixedly connected with bear box 1 by the first bolt 6, described half flange 4 is fixedly connected with ring flange 3 by the second bolt 7, be provided with centre frame worm gear 5 between described ring flange 3 and the half flange 4, described centre frame worm gear 5 is set on the ring flange 3, described ring flange 3 one sides are provided with two worm brackets 14, described worm bracket 14 is fixedly connected with bear box 1 by the 3rd bolt 17, be provided with worm screw 15 between described two worm brackets 14, described worm screw 15 is intermeshing with centre frame worm gear 5, be coated with top 9 in the middle of the described centre frame worm gear 5, be provided with external screw thread on described top 9 outer walls, be provided with internal thread on described centre frame worm gear 5 inwalls, described internal thread and external screw thread are intermeshing, also be provided with feather key 10 on described top 9 outer walls, offer gathering sill on described ring flange 3 and centre frame worm screw 5 inwalls, described feather key 10 is installed in the gathering sill.
Be provided with copper sheathing 18 between described worm screw 15 and the worm bracket 14.
In actual the use, middle auxiliary bearing is placed on the boring bar in advance the top minimum dimension that transfers to, place stern pipe middle part, in transferred in the school, the personality board hand operated worm screw of a lengthening of design rotated, by the rotation of worm screw, drive worm gear and rotate, because the worm gear endoporus has internal thread, external screw thread is arranged on top, they are intermeshing, and when worm gear rotated, top also the work rotated accordingly, and being housed on top, a feather key limits its rotation, so that top can only moving up and down along feather key.
When worm screw was rotated towards a direction, so that top stretching out, boring bar so that four top difference support securely on the stern inside pipe wall, made intermediate bearing reach result of use according to the gap difference rotary worm of four direction.
