Abstract

The invention relates to a disassembling tool for a tail bearing. The disassembling tool comprises a stem tube (1), a bearing (2) and a screw rod (3), wherein rubber (4) and sealing plates (5) are arranged on the two sides of the bearing (2) in sequence; the rubber (4) and the sealing plate (5) inside the bearing (2) are fixed through a first pressing plate (6); the rubber (4) and the sealing plate (5) outside the bearing (2) are fixed through a first nut (7); a plurality of jacks (8) are fixedly arranged on the end face of the stem tube (1); a fixed plate (9) is arranged at the ends of the jacks (8); a second pressing plate (10) is arranged outside the fixed plate (9); the first pressing plate (6) and the second pressing plate (10) are connected with the screw rod (3) through a second nut (11). According to the disassembling tool for the tail bearing disclosed by the invention, bearings which are not arranged in place or dislocated bearings can be pulled out for cooling installation again, so that the problem that an existing tail bearing is not arranged in place is well solved.

Description

Tail bearing disassembling fixture
Technical field
The present invention relates to a kind of tail bearing disassembling fixture, belong to and build ship technical field.
Background technology
Certain is taken turns water lubrication tail bearing and renews, material is synthetic resin, in freezing installation process because the mounting distance stroke having is long, the long phenomenon that causes refrigerating effect variation and occur not put in place of set-up time, as circumferential position deviation or the axial situation such as not in place, conventional processing method is that request shipowner gives way or is pressed into by force or destroys with oil pump the solution of reforming, this just exerts an influence to the installation effect of final tail bearing, if reformed, also can increase extra cost, extended the duration, shipowner's satisfaction is poor.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, a kind of tail bearing disassembling fixture is provided, it can be pulled out and re-start freezing installation again bearing not in place or dislocation is installed, and has solved well tail bearing in the past problem not in place is installed.
The object of the present invention is achieved like this: a kind of tail bearing disassembling fixture, it comprises stern pipe and bearing and screw mandrel, described bearing is arranged in stern pipe, described screw mandrel is threaded onto in bearing, described bearing both sides arrange and are disposed with rubber and shrouding, rubber and the shrouding of described bearing inner side are fixed by the first pressing plate, rubber and the shrouding in described bearing outside are fixed by the first nut, on described stern end surfaces, be fixedly installed a plurality of jack, described a plurality of jack end is provided with fixed head, described screw mandrel outer end is through fixed head, described fixed head arranged outside has the second pressing plate, on described the first pressing plate and the second pressing plate end face, offer installing hole, in described installing hole, be provided with the second nut, described the first pressing plate is connected with screw mandrel by the second nut with the second pressing plate, described stern pipe outer setting has CO 2tracheae, described CO 2tracheae stretches into bearing inside.
Compared with prior art, the present invention has following beneficial effect:
A kind of tail bearing disassembling fixture of the present invention, it seals bearing two ends, by pour into CO in bearing 2gas shrinks by bearing freezing, by additional pressing plate and jack, act on simultaneously, can bearing be pulled out by less soil fertility like this, be unlikely to damage bearing, thereby make the bearing of pulling out can re-start again freezing installation, solved well tail bearing in the past problem not in place is installed, reduced cost, shorten the duration, improved shipowner's satisfaction.
