Description

Technical Field

[0001] This utility model relates to the field of MVR technology, and in particular to a centering tooling for a steam compressor in an MVR system. Background Technology

[0002] The core equipment of an MVR system typically consists of an electric motor (drive source), a gearbox (speed increaser, optional), and a steam compressor (centrifugal or Roots type). The output end of the motor and the input end of the gearbox are connected by a coupling. Before installing the coupling, the relative positions of the motor and gearbox need to be adjusted. Current adjustment methods generally involve measuring with a dial indicator, which is fixed to the output shaft of the motor via a magnetic base. The measuring end of the dial indicator rests against the outer diameter or end face of the gearbox input shaft, requiring multiple measurements on the end face and outer diameter, resulting in low efficiency in adjustment and assembly. Furthermore, the magnetic base has many components, and the dial indicator is far from the fixed end of the base, making installation cumbersome and further affecting adjustment efficiency. Additionally, slight vibration of the dial indicator can further affect adjustment accuracy. Utility Model Content

[0003] The purpose of this invention is to provide a centering fixture for a steam compressor in an MVR system. By integrating two measuring gauges onto the same fixture, the installation of the fixture can be facilitated, and the end face and outer circle can be measured simultaneously. This can effectively improve the efficiency and accuracy of the adjustment, thereby improving the assembly accuracy of the motor and gearbox and enhancing the stability of the equipment operation.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0005] A centering fixture for a steam compressor in an MVR system includes an electric motor, a gearbox, and the centering fixture itself. A first flange is fixed to the motor shaft of the electric motor, and a second flange is fixed to the input shaft of the gearbox.

[0006] The alignment fixture includes an end face measuring gauge, an outer diameter measuring gauge, a first bracket for fixing the end face measuring gauge, and a second bracket for fixing the outer diameter measuring gauge. The first bracket is fixed to the first flange, and the second bracket is connected to the first bracket. The end face measuring gauge and the outer diameter measuring gauge are dial indicators. In use, the measuring end of the end face measuring gauge rests against the end face of the second flange, and the measuring end of the outer diameter measuring gauge rests against the outer diameter of the second flange. By rotating the first flange, the end face measuring gauge and the outer diameter measuring gauge can measure at their respective positions on the second flange. The height and horizontal position of the motor are adjusted according to the runout of the end face measuring gauge and the outer diameter measuring gauge, so that the first flange and the second flange are coaxially aligned. This alignment fixture is easy to install, significantly reducing the installation time before measurement. Furthermore, having the end face measuring gauge and the outer diameter measuring gauge on the same fixture improves measurement accuracy, reduces the number of motor position adjustments, and improves assembly accuracy and efficiency.

[0007] The present invention is further configured such that the first bracket is detachably connected to the first flange by screws, thereby allowing the centering fixture to be reused.

[0008] The present invention is further configured such that: the first bracket is formed with a slot, and the radial insert plate of the second bracket is inserted into the slot; the radial insert plate is formed with an adjustment groove, and the corresponding screw passes through the adjustment groove and is screwed onto the first flange; the radial insert plate is clamped between the first flange and the slot, and the position of the outer diameter measuring gauge can be adjusted by inserting the radial insert plate into different positions in the slot, thereby adapting to the measurement needs of flanges with different outer diameters and improving the practicality and adaptability of the tooling.

[0009] The present invention is further configured such that: a threaded hole is formed on the side wall of the slot, and a locking screw is screwed into the threaded hole. The locking screw abuts against the side wall of the radial insert plate, and the radial insert plate can be pressed by the locking screw, thereby preventing the radial insert plate from moving in the slot and improving the measurement accuracy.

[0010] The present invention is further configured such that: a meter box is fixed on each of the second bracket and the first bracket, and the dials of the end face measuring meter and the outer circle measuring meter are respectively installed in the corresponding meter box, so that the measuring meters can be protected by the meter box.

[0011] The outstanding effect of this utility model is:

[0012] Compared with existing technologies, by integrating two measuring instruments onto the same tooling, the tooling can be installed more conveniently and the end face and outer circle can be measured simultaneously. This can effectively improve the efficiency and accuracy of the assembly, thereby improving the assembly accuracy of the motor and gearbox and enhancing the stability of the equipment operation.

[0013] The position of the external diameter measuring gauge can be adjusted by using the first bracket on the second bracket, thus adapting to the needs of various working conditions. Attached Figure Description
