Description
Technical field
The utility model proposes the stripping assembly of ship stern tubular shaft, be applicable to the bearing cartridge dismounting of ship stern tubular axis hole, be specially adapted to the bearing lining dismounting of large ship.
Background technology
Nowadays, in large, medium and small ship building process, in the building berth stage, it is all the most important thing that stern pipe bow stern bearing is installed, and is all mostly to adopt interference fit between bearing and hole, by the pressing sleeve tool of specialty, ensure that bearing is correctly press-fit into place, simultaneously the later stage measures the gap of axle and bearing, axis hole cleanliness level, the clean degree of oil and axle system load etc., and meet technological requirement, boats and ships could navigate by water smoothly.
Boats and ships are in manufacture process or long-time running, and the replacing of bearing is also a large difficult point, and bearing needs the device of specialty to dismantle bearing.Due to various ships bearing type and size dimension inconsistent, entirely do not possess supporting professional device.Some factories adopt special frock to fix magnetic drill, carry out groove milling by the grabage shoot of bearing, bearing two side milling is broken, then removes.The factory also had uses the mode of gouge to carry out destructiveness to bearing and removes.Above method can not ensure the integraty of bearing, and stern tube shaft hole surface also may be caused to wear and tear.
Summary of the invention
In order to make tube shaft bearing convenient disassembly, the utility model provides the stripping assembly of ship stern tubular shaft.This device, by leading screw and pressing plate and hydraulic top, solves the technical matters of ship stern pipe neck bearing dismounting.
The scheme that the utility model technical solution problem adopts is:
In the bearing of ship stern pipe, be interspersed with screw mandrel, hydraulic top is equipped with by the first nut sleeve in screw mandrel one end, and hydraulic top contacts with the first drill drift pressing plate being arranged on bearing side, and the first drill drift pressing plate withstands on the side of bearing; The opposite side screw mandrel of bearing is provided with the second drill drift pressing plate by the second screw.Hydraulic top is connected with Hydraulic Pump by hydraulic pipe.Second drill drift pressing plate is installed with four to 6 round steel, and is welded with reinforced rib.
Good effect, adopt the utility model stripping assembly dismounting screw shaft of ship bearing to have and do not destroy bearing hole, be convenient to execute-in-place, dismantle effective, speed is fast, saves the advantage of man power and material.Be suitable for applying as the stripping assembly of screw shaft of ship bearing.

Detailed description of the invention
According to the figure, at ship stern pipe 0 built with bearing 01.
In the bearing of ship stern pipe, be interspersed with screw mandrel 1, screw mandrel one end is set with hydraulic top 3 by the first screw 2, and hydraulic top contacts with the first drill drift pressing plate 4 being arranged on bearing side, and the first drill drift pressing plate withstands on the side of bearing; The opposite side screw mandrel of bearing is provided with the second drill drift pressing plate 5 by the second screw 6.
Hydraulic top is connected with Hydraulic Pump 7 by hydraulic pipe.
Second drill drift pressing plate is installed with four to 6 round steel 4.1, and is welded with reinforced rib 4.2.
Use of the present utility model:
First the first drill drift pressing plate of bearing is penetrated in stern tube shaft bearing bore, and be stuck in bearing bore diameter and prop up on mouth, then run through bearing first drill drift pressing plate by leading screw, lock hydraulic top with screw; With crane, the second drill drift pressing plate is arranged on leading screw, makes the second drill drift pressing plate front end face and stern pipe neck bearing aft end face fit simultaneously; Hydraulic top is connected with Hydraulic Pump 7 by hydraulic pipe, by the pressurization to Hydraulic Pump, promotes the first drill drift pressing plate, by screw mandrel and the second drill drift pressing plate function, is released by bearing in ship stern pipe, realizes the dismounting of bearing.
The utility model utilizes two drill drift pressing plates; a pressing plate end face is machinework plane; be fixed on stern pipe aft end face; another pressing plate end face is that non-machined face and hydraulic top are fitted; two pressing plates are by 4 or 6 round bar weld togethers; this bearing drill drift frock pressing plate optimal design improves the spatial dimension that bearing is extracted out, makes lifting convenient simultaneously; And the second bearing drill drift pressing plate adopts racetrack design concept, racetrack design goal to be ensure that frock can penetrate in stern pipe smoothly.Due to narrow space in stern pipe, operated by personnel is inconvenient, and adopt semicircular arc-shaped design at the pressing plate back side, object plays the effect of stop, facilitates the installation of workman.Simultaneously in order to ensure the intensity of drill drift pressing plate, strengthening gusset in the design of pressing plate pros and cons, improving intensity, bearing can be extracted out smoothly.
