Abstract
A kind of turbine rotor proof adjustable axle of the present invention alters device, comprise base, the anterior left and right sides of base is symmetrically arranged with left fixing ear and ear is fixed on the right side, left fixing ear is installed with left adjustment jackscrew, right fixing ear is installed with right adjustment jackscrew, and left adjustment jackscrew left end and right adjustment jackscrew right-hand member are provided with the red copper plush copper that can withstand on rotor journal convex shoulder; The rectangular bolt hole that in the middle of base rear portion, left and right extends before and after being arranged side by side two, be installed with left fixing bolt and right fixing bolt in two rectangular bolts hole respectively, base is fixed on turbine bearing pad side by left fixing bolt and right fixing bolt.The invention has the beneficial effects as follows: realize axial float power when balancing rotor dish moves, axial displacement is there is when avoiding rotor disk to move, collision and the friction of rotor and static part can not be caused when steam turbine installation, maintenance process because coiling rotor, ensure that the device security of power station core component.
Description
Technical field
The present invention relates to a kind of turbine rotor proof adjustable axle and alter device.
Background technique
Along with making constant progress of China's electricity market, the single-machine capacity of Turbo-generator Set constantly increases, and rotor also strengthens (1000MW level low pressure rotor reaches more than 90t) as its boundary dimension of core component of steam turbine and weight thereupon.The thing followed is in rotor installation, maintenance process, its axial float power when moving rotor of coiling also strengthens, as can not this play power of active balance, move in process to cause at rotor disk and turn turbine rotor proof adjustable axle and alter device and cause rotor and the static part such as dividing plate, bearing shell generation sound is collided, bring hidden danger to device security.
Summary of the invention
For solving above technical deficiency, the invention provides a kind of turbine rotor proof adjustable axle and altering device
The present invention is achieved by the following measures:
A kind of turbine rotor proof adjustable axle of the present invention alters device, comprise base, the anterior left and right sides of described base is symmetrically arranged with left fixing ear and ear is fixed on the right side, a described left side is fixed on ear and is installed with left adjustment jackscrew, right fixing ear is installed with right adjustment jackscrew, and left adjustment jackscrew left end and right adjustment jackscrew right-hand member are provided with the red copper plush copper that can withstand on rotor journal convex shoulder; The rectangular bolt hole that in the middle of described base rear portion, left and right extends before and after being arranged side by side two, be installed with left fixing bolt and right fixing bolt in two rectangular bolts hole respectively, base is fixed on turbine bearing pad side by left fixing bolt and right fixing bolt.
Above-mentioned base is T-shaped, and base front portion to the left and right both sides is extended with bump, and a described left side is fixed ear and the right side and fixed ear and be separately fixed on two bumps.
The longitudinal section of above-mentioned red copper plush copper is U-shaped.
The invention has the beneficial effects as follows: realize axial float power when balancing rotor dish moves, axial displacement is there is when avoiding rotor disk to move, collision and the friction of rotor and static part can not be caused when steam turbine installation, maintenance process because coiling rotor, ensure that the device security of power station core component.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Wherein: 1 base, 2 left fixing ears, 3 right fixing ears, 4 left adjustment jackscrews, 5 right adjustment jackscrews, 6 left fixing bolts, 7 right fixing bolts, 8 turbine bearing pads, 9 rotor journals.
Embodiment
Below in conjunction with accompanying drawing, further detailed description is done to the present invention:
As shown in Figure 1, a kind of turbine rotor proof adjustable axle of the present invention alters device, comprise base 1, the anterior left and right sides of base 1 is symmetrically arranged with left fixing ear 2 and ear 3 is fixed on the right side, left fixing ear 2 is installed with left adjustment jackscrew 4, right fixing ear 3 is installed with right adjustment jackscrew 5, and left adjustment jackscrew 4 left end and right adjustment jackscrew 5 right-hand member are provided with the red copper plush copper that can withstand on rotor journal 9 convex shoulder; The rectangular bolt hole that in the middle of base 1 rear portion, left and right extends before and after being arranged side by side two, is installed with left fixing bolt 6 and right fixing bolt 7 in two rectangular bolts hole respectively.Base 1 is T-shaped, and base 1 front portion is extended with bump in both sides to the left and right, and left fixing ear 2 and the right side are fixed ear 3 and be separately fixed on two bumps.
Base 1 is fixed on turbine bearing pad 8 side by left fixing bolt 6 and right fixing bolt 7, it is interior and fastening that left fixing bolt 6 and right fixing bolt 7 screw in bearing shell watt cover through rectangular bolt hole, left fixing ear 2 and the right side are fixed ear 3 and are welded on front side of base 1, left adjustment jackscrew 4 and right adjustment jackscrew 5 are welded into U-shaped red copper plush copper and screw in fixing ear respectively in end, and red copper plush copper end withstands on the convex shoulder of rotor journal 9, when this hour indicator moves rotor, rotor has just been carried out axial location by left adjustment jackscrew 4 and right adjustment jackscrew 5, prevents the axial displacement of rotor.
Two long strip bolts hole on base 1, can adjust whole device near rotor or away from rotor, only left fixing bolt 6 and right fixing bolt 7 need be unclamped, device is outwards moved away from rotor when rotor hangs in and hang out time.The red copper plush copper of left adjustment jackscrew 4 and right adjustment jackscrew 5 end can ensure while rotor axial position, location can not damaging rotor body, but also the effect of the axial position of finely tuning rotor can be realized, as need slightly toward front end movable rotor, then right adjustment jackscrew 5 is unclamped the numerical value needing adjustment, rotor is moved with hub disk, always screw left adjustment jackscrew 4 until the red copper plush copper of end touches rotor convex shoulder in the process of the dynamic rotor of dish, then complete moving axially of needs.
The above is only the preferred implementation of this patent; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the art of this patent principle; can also make some improvement and replacement, these improve and replace the protection domain that also should be considered as this patent.
