Description
Technical field
The invention belongs to the mounting process fields of ship equipment, and in particular to one kind seizes axle generator with magneto
Shafting Alignment of Vessels in technique.
Background technique
In the 10,000 tons roll-on-roll-off ship of a new generation, magneto seizes axle generator because its is compact-sized, efficiency is distinguished, turns
The favors of the advantages increasingly by roll-on-roll-off ship designer such as sub- inertia and weight are low.But magneto seizes axle generator producer pair
Clipping room between stator and rotor is away from there is strict demand, once being unsatisfactory for requiring, axle generator be will be unable in ship's navigation
Normal power generation；And due to the limitation of manufacturing process, magneto seizes the stator faces of axle generator and rotor end-face and can not protect
Card is all completely in identical gap on whole circumference face, therefore can generate permanent magnetism between the permanent magnet and stator on rotor
Power, this permanent magnetic can make armature spindle shift.Method is that magneto is first seized axis band in traditional Shafting Alignment of Vessels
Generator is whole after shop assembled is good to hang on ship, then adjusts each shafting position and the Axial Status of real ship is finally made to meet axis
It is the requirement of alignment calculation book.But due to the presence of permanent magnetic, armature spindle is big with permanent magnetic always during adjustment
Small and direction change and occur carrying out the change in displacement of all directions always, variation of the entire Axial Status also with permanent magnetic
And changing always, field worker have to pass through many times repeat adjustment could by shafting installation in place, and a new generation
On 10,000 tons roll-on-roll-off ship, most light axis is also up to several tons of weights, and the workload of field worker is very huge and the period is longer.Therefore
In order to reduce the workload of field worker, shorten the construction period of field worker, it is necessary to using a kind of novel marine shafting peace
Dress technique solves the above problems.
Summary of the invention
The technical problem to be solved by the present invention is to allow field worker how to use least workload within the shortest time
Quickly the marine shafting for seizing axle generator with magneto is installed in place, and end-state meets centering of shafting calculated description
It is required that.
It is a kind of to seize technique in the Shafting Alignment of Vessels of axle generator with magneto, comprising the following steps:
S1, computational theory value: it calculates the corresponding shafting on the basis of final Axial Status and is bolted under state respectively
Load value at bearing；It is not connected in shafting bolt after calculating the PM rotor removal that magneto is seized to axle generator
GAP value and SAG value under state between each shafting end face of flange, and corresponding shafting are bolted under state at each bearing
Load value；
S2, it PM rotor is seized from magneto is temporarily removed on the armature spindle of axle generator, first by axis at this time
It is the Axial Status for the not permanent magnet that state is adjusted to meet on step S1, then adjusts magneto and seize axle generator
Axle generator position of stator makes the center line of shaft generator machine stator consistent with the center line of armature spindle；
S3, PM rotor is attached on armature spindle, fine adjustment shaft band generator unit stator simultaneously makes Axial Status meet step S1
On final Axial Status.
Specifically, step S1 includes:
S101, each shafting bolt are in connection status, carry out closing Spindle Status calculating: in the state of installing PM rotor
Calculate the load value in shafting at fore bearing and intermediate bearing and corresponding position of bearings；
S102, PM rotor is removed, keeps each position of bearings constant, at this time shadow of the shafting due to removing permanent magnetic
It rings, the load value at new fore bearing and intermediate bearing is calculated in the case where closing Spindle Status；
S103, remove each shafting bolt, calculate GAP value between tailing axle and rotor shaft flange and SAG value and armature spindle and
GAP value and SAG value between host flange.
Specifically, step S2 specifically:
S201, PM rotor is seized in axle generator from magneto and is removed；
S202, the position for determining tailing axle: tailing axle is placed into the position required in centering of shafting calculated description and fixation；It determines
The position of armature spindle: adjusting the position of armature spindle by adjusting the height of temporary support point, so that adjustment tailing axle and armature spindle
The GAP value and SAG value obtained in GAP value and SAG value and step S1 between flange is consistent；
S203, the position for determining host: bolt is adjusted by host to adjust the position of host, so that armature spindle and host
The GAP value and SAG value obtained in GAP value and SAG value and step S1 between flange is consistent；
S204, each shafting bolt is in connection status, required according to centering of shafting calculated description in fore bearing and jackshaft
It holds side and Jacking point progress load jacking work is respectively set；
S205, adjustment magneto seize the position of the adjusting bolt of axle generator pedestal to ensure shaft generator machine stator
Center line it is consistent with the center line of armature spindle.This step eliminates in follow-up work under original state because of shaft generator machine stator
Additional permanent magnetic that is eccentric and generating is in rotor.
Specifically, it is unsatisfactory for centering of shafting calculated description requirement as jacked the bearing load in result in step 204, according to
The pedestal of the adjusting bolt and host that jack data point reuse intermediate bearing pedestal adjusts bolt to adjust the load point of entire shafting
Match, so that jacking result meets centering of shafting calculated description requirement.This step has determined in addition to magneto seizes axle generator
Shaft components position.
Specifically, PM rotor is specially installed on armature spindle by step S3, and at fore bearing and intermediate bearing
Jacking point carry out load jacking again, make each bearing go out load value meet step S1 theoretical value requirement.
Specifically, step S1 requirement is unsatisfactory for as jacked the bearing load in result, according to jacking data tune in step S3
Whole magneto seizes the adjusting bolt on axle generator pedestal to adjust the sharing of load of entire shafting, so that jacking result is full
Theoretical value requirement in sufficient step S1.
Beneficial effects of the present invention
Magneto effectively can be seized the permanent magnetic on axle generator to entire centering of shafting process by the present invention
Influence is preferably minimized, and not only ensure that the installation quality of marine shafting, but also has saved the construction cost of shipyard, while also reducing ship
The shipbuilding period of factory.
