Abstract
The invention provides an adjustable axial-endplay preventing device for a steam turbine rotor. The adjustable axial-endplay preventing device comprises a base. A left fixing lug and a right fixing lug are symmetrically arranged on the left side and the right side of the front portion of the base, a left adjusting jackscrew penetrates through the left fixing lug, a right adjusting jackscrew penetrates through the right fixing lug, and the left end of the left adjusting jackscrew and the right end of the right adjusting jackscrew are provided with red copper raised heads respectively which can abut against a raised shoulder of a shaft neck of the rotor. Two strip bolt holes which stretch forward and backward are formed in the middle of the rear portion of the base laterally side by side, a left fixing bolt and a right fixing bolt penetrate through the two strip bolt holes respectively, and the base is fixed to the side face of a bearing pad of a steam turbine through the left fixing bolt and the right fixing bolt. The adjustable axial-endplay preventing device has the advantages that axial endplay force in the shaft turning process of the rotor is balanced, axial displacement generated in the shaft turning process of the rotor is avoided, collision and friction of the rotor and a static part generated due to shaft turning of the rotor can be avoided in the overhaul process, and equipment safety of core parts of a power plant is guaranteed.
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 reached 90t more than) as its boundary dimension of core component of steam turbine and weight thereupon.The thing followed is in rotor installation, maintenance process, during the moving rotor of dish, its axial float power also strengthens, as can not this play power of active balance, in the moving process of rotor disk, will cause that turning turbine rotor proof adjustable axle alters device and cause the static part generation sound such as rotor and dividing plate, bearing shell and collide, and brings 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 alter device
The present invention is achieved by the following measures:
A kind of turbine rotor proof adjustable axle of the present invention is altered device, comprise base, the anterior left and right sides of described base is symmetrically arranged with left fixedly ear and right fixedly ear, a described left side is fixedly installed with left adjustment jackscrew on ear, the right side is fixedly installed with right adjustment jackscrew on ear, 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, extend before and after being arranged side by side two left and right, is installed with respectively left fixing bolt and right fixing bolt in two rectangular bolts hole, base is fixed on turbine bearing pad side by left fixing bolt and right fixing bolt.
Above-mentioned base is T shape, and base front portion to the left and right both sides is extended with bump, and a described left side fixedly ear is separately fixed on two bumps with right fixedly ear.
The longitudinal section of above-mentioned red copper plush copper is U-shaped.
The invention has the beneficial effects as follows: realize the axial float power of balancing rotor dish when moving, while avoiding rotor disk moving, there is axial displacement, when steam turbine installation, maintenance process, can because coiling rotor, not cause collision and the friction of rotor and static part, guarantee 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 fixedly ears, 3 right fixedly 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, the present invention is done to further detailed description:
As shown in Figure 1, a kind of turbine rotor proof adjustable axle of the present invention is altered device, comprise base 1, the anterior left and right sides of base 1 is symmetrically arranged with left fixedly ear 2 and right fixedly ear 3, a left side is fixedly installed with left adjustment jackscrew 4 on ear 2, the right side is fixedly installed with right adjustment jackscrew 5 on ear 3, and left adjustment jackscrew 4 left ends and right adjustment jackscrew 5 right-hand members are provided with the red copper plush copper that can withstand on rotor journal 9 convex shoulders; The rectangular bolt hole that in the middle of base 1 rear portion, extend before and after being arranged side by side two left and right, is installed with respectively left fixing bolt 6 and right fixing bolt 7 in two rectangular bolts hole.Base 1 is T shape, and base 1 front portion is extended with bump in both sides to the left and right, and left fixedly ear 2 and right fixedly ear 3 are separately fixed on two bumps.
Base 1 is fixed on turbine bearing pad 8 sides by left fixing bolt 6 and right fixing bolt 7, left fixing bolt 6 and right fixing bolt 7 screw in bearing shell watt cover also fastening through rectangular bolt hole, left fixedly ear 2 and right fixedly ear 3 are welded on base 1 front side, left adjustment jackscrew 4 and right adjustment jackscrew 5 are welded into U-shaped red copper plush copper and screw in respectively fixedly in ear in end, and red copper plush copper end withstands on the convex shoulder of rotor journal 9, during the moving rotor of this hour indicator, left adjustment jackscrew 4 and right adjustment jackscrew 5 have just carried out axial location by rotor, have prevented the axial displacement of rotor.
Two long strip bolts hole on base 1, can adjust whole device near rotor or away from rotor, when rotor hangs in and hang out, only left fixing bolt 6 and right fixing bolt 7 need be unclamped, and device is outwards moved away to rotor.The red copper plush copper of left adjustment jackscrew 4 and right adjustment jackscrew 5 ends can guarantee can not damage rotor body in rotor axial position, location, but also can realize the effect of axial position of fine setting rotor, as need forward end movable rotor slightly, right adjustment jackscrew 5 is unclamped to the numerical value that needs adjustment, with the moving rotor of hub disk, process at the moving rotor of dish always screws left adjustment jackscrew 4 until the red copper plush copper of end touches rotor convex shoulder, completes moving axially of needing.
The above is only the preferred implementation of this patent; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the art of this patent principle; can also make some improvement and replacement, these improvement and replacement also should be considered as the protection domain of this patent.
