Problems solved by technology

Due to the same installed capacity, the steam turbine rotors of the steam turbine generator sets of different manufacturers are different, the steam turbine rotors of the steam turbine generator sets of the same manufacturer and different installed capacity are different, the distance between the steam turbine rotor and the bearing seat is different, and the oil system pipeline layout method in the bearing seat is different. Different, so in the maintenance of the unit, it is usually necessary to use special racking tools of different models and styles, which greatly rewards the work efficiency and maintenance cost for the huge trouble caused by the maintenance work

Embodiment 1

[0046] Such as Figure 1-3As shown, first pass the expansion rod 1 through the bolt hole of the coupling on either side, and after the tapered side of the expansion rod is penetrated from the corresponding bolt hole, the split expansion sleeve 5 is inserted into the bolt hole. The bolt holes are combined into a full circle (smear lubricating oil on the outer circle of the expansion valve of the split sleeve and the bolt hole), so that the expansion rod passes through the full circle of the split sleeve, and put the lock washer on the left 4 After inserting, tighten the left locking positioning nut 3. On the other side of the expansion rod, rotate and adjust the right positioning lock nut 6, so that the dial indicator support 2 is in the proper axial position of the rotor, put the right locking washer 11, and put the dial indicator support (2 ), adjust the position of the dial indicator support 2 on the coupling circumference, put in the second right locking washer 10, and tig...

Embodiment 2

[0048] If the distance between the coupling and the bearing box is small and the circumference measuring dial indicator cannot pass through normally, the circumference dial indicator can be removed and then screwed in the high-precision screw 9 to complete the measurement of the circumference data through the high-precision screw, further increasing the The practicality of the invention.

[0049] The present invention can be applied to a convenient and convenient measuring tool for the shafting alignment of different types of steam turbines. The present invention can meet the requirements of different bolt diameters, different rotor alignment wheels and bearing seat distances through the adjustment of the outer diameter of the split expansion sleeve and the switching of high-precision screws. Coupling needs to find the center; the invention has strong operability, high efficiency, wide application range, can avoid all unnecessary errors, and ensure the accuracy of measurement d...

Abstract

The invention discloses a convenient and fast steam measuring tool turbine shafting alignment, comprising a tensioning rod; two ends of the tensioning rod respectively penetrate into coupling bolt holes formed at the two sides of a rod body, and the tensioning rod is fixed by means of a locking and positioning piece; a dial indicator support is fixed at one side of the tensioning rod, and a high precision screw is arranged on the dial indicator support; the tensioning rod is a tapered variable-diameter rod body which is thicker at the middle part and smaller at the two ends; two positioning screw rods are respectively arranged at the two ends of the tensioning rod; the positioning screw rod at the left side of the tensioning rod passes through the coupling bolt hole formed at the left sideof the tensioning rod, and is fixed with a coupler at the left side by means of a left locking and positioning nut and a left locking washer which are positioned on the positioning screw rod at the left side. The convenient and fast measuring tool is suitable for measuring shafting alignment of steam turbines with different models; the convenient and fast steam turbine shafting alignment measuring tool can meet the requirements of different bolt diameters and different rotors for coupling alignment between a wheel and a bearing seat by adjusting the diameter of the outer circle of a split type tensioning sleeve and switching the high precision screw; the convenient and fast steam turbine shafting alignment measuring tool is high in operability and efficiency and wide in application scope,can avoid all unnecessary errors, and guarantees the accuracy of measured data.
