Description
Technical field
The method that is controlled the present invention relates to the positioning for the pull rod around reaction wheel to rotor disk and
Device.
Background of invention
Reaction wheel for producing the industrial equipment of electric energy generally includes multiple bladed rotor disks, these rotors
Disk is aligned along axis, and is coupled at forepart.The connection of the forepart between adjacent rotor disk is obtained by means of HIRTH connectors.
Therefore, there are two corresponding radial direction ring gears for each rotor disk setting, that is, so-called HIRTH teeth group is set on each face
There are one putting.These rings are attached to the ring of adjacent disk, in order to build so-called HIRTH connectors.
Rotor disk is provided with corresponding blade group, also, bundled by center pull rod it is stacked, wherein, center pull rod connects
Close the corresponding centre bore of rotor disk.
It is each to fill vaned disk restriction compressor or turbine rotor stage.
It must be produced with highest precision and assemble reaction wheel, in order to ensure the balance of almost Perfect.Consider
To quality and high rotating speed (depending on the standard of country variant, rotor is usually rotated with 3000 rpm or 3600 rpm), even if most
The defects of small, may also lead to the dangerous vibration more than tolerable limit, thus equipment is forced to stop, and be intended to make to shake to carry out
The dynamic correction intervention for restoring tolerable limit.
The assembling of rotor is related to surrounding rotor disk into the center pull rod stacking for being arranged in vertical position at present.Due to by upper
The HIRTH heel teeths stated and the fact that realize the contact between disk, rotor disk is caused automatically to make itself placed in the middle.
The assembling of rotor, which usually requires that, stacks a large amount of rotor disk (for example, about 20).Therefore, (for example, due to
Disk has the fact that nonparallel multiple faces) the only one disk in these disks lacks uniformity this situation and is enough stacking
It obtains to tilt at the end of step and stack, that is, the stacking that the center of most hub disk is not aligned with the center vertical of first disk.
When having clipped rotor and possible corrective action often requires that dismounting rotor usually to the compliance of disk
(compliance) it is controlled.
In addition, currently available tool and method expends long time to assess and correct stacking.Before stacking,
By the inspection of the compliance to control panel, but this all non-compliance for not ensuring to detect disk, because operating personnel need
Carry out activity and personal assessment by hand.Therefore, check and correct required accuracy and the time be not to be regarded as it is satisfactory
's.
It is important, therefore, that it is controlled with the positioning for the pull rod around reaction wheel to rotor disk
Method, this method is accurate and reliable, also, avoids or minimize the generation of balance error.Thereby, it is possible to avoid or minimize
Assessment to be carried out and correct operation at the rotor clipped.
