Description

Technical Field

[0001] The utility model relates to a vertical device for erecting a rotor of a high-voltage vertical motor, belonging to the technical field of motor equipment. Background Technique

[0002] At present, high-voltage vertical motors are widely used in the market and are usually used in industrial applications with high power output and limited space, such as compressors, water pumps, fans, and mining equipment. High-thrust bearings are the preferred bearings for high-power high-voltage vertical motors. These bearings are costly. During the assembly process, in order to protect them safely and effectively and successfully assemble them, we need to design and manufacture a tooling for erecting the motor rotor.

[0003] In the current motor assembly technology, the horizontal assembly method of the rotor is usually adopted. For motors equipped with high-thrust bearings, this horizontal assembly method cannot fix the rollers in the bearings well, and the rollers are prone to falling, which is likely to cause fatal damage to the bearings.

[0004] In view of the problems in the above background technique, it is necessary to design a rotor erecting device for the rotor of a motor equipped with a high-thrust bearing. Content of the Utility Model

[0005] In view of the problems existing in the above-mentioned prior art, the utility model provides a vertical device for erecting a rotor of a high-voltage vertical motor, thereby solving the above technical problems.

The above threaded holes and waist-shaped holes are used for mating and connecting with the ground workbench for fixing, and the above fixing holes are used for fixedly connecting with the support bottom angle plates on the support components.

[0007] Further, the support component includes a support leg plate and a support bottom angle plate; the support bottom angle plate is arranged under the support leg plate.

[0008] Further, the support leg plate includes a trapezoidal main board and a lower connecting board; the trapezoidal main board and the lower connecting board are integrally connected; an opening groove one is opened at the bottom of the lower connecting board, which is used for mating and connecting with the support bottom angle plate.

[0009] Further, the support bottom angle plate is a long strip plate, and symmetrically arranged waist-shaped holes are opened on the left and right sides in the length direction, which are used for fixedly connecting with the base plate. Symmetrically arranged opening grooves two are opened on the left and right sides in the width direction; the support bottom angle plate is fixedly connected to the bottom of the support leg plate through the opening grooves two on both sides.

[0010] Furthermore, a plurality of opening grooves three which are the same in number as the support leg plates are uniformly arranged at the circumferential outer diameter surface around the support flange ring plate; the support flange ring plate is clamped and fixed with the vertical inner side surface of the support leg plate through the opening grooves three.

[0011] Furthermore, a keyway is arranged at the inner diameter surface of the support flange ring plate; the keyway is used for mating connection with the keyway on the rotor shaft.

[0012] Furthermore, 6 groups of the support assemblies are provided and are uniformly arranged on the upper end surface of the base plate.

[0013] The beneficial effects of the present utility model are as follows: By adopting the above-mentioned tooling, the matching dimensions can be designed according to the keyway and shaft shoulder dimensions on the rotor shaft, effectively controlling the axial and radial movement of the rotor in the erected state, and ensuring the safe and smooth assembly of the high-thrust bearing of the high-voltage motor.
