Problems solved by technology

The general impeller and motor assembly method is to install the impeller on the motor shaft by hammering (pressing method). Due to the uneven force during the pressing process, it is difficult to control the force, and the impact force directly acts on the motor, and it is easy to Causes damage to the motor bearing, which is difficult to find during assembly, which directly affects the safety performance and service life of the nuclear power fan in the later stage

Embodiment Construction

[0010] The present invention will be further described below in conjunction with accompanying drawing:

[0011] like figure 1 , 2 A motor bearing installation and protection device for a nuclear axial flow fan is shown, including a first assembly plate 1, a second assembly plate 2, a third assembly plate 3, an assembly tool shaft 4, a first assembly plate 1, and a second assembly plate 2 3. The third assembly plate 3 is assembled and formed by bevel welding, and the relative angle between each assembly plate is 120°. The assembly tool axis 4 is connected with the assembly plate fillet welding at the axis position of the assembly plate assembly, and each assembly plate A jack 5 is arranged on the top pad.

[0012] The above is only a preferred embodiment of the present invention, it should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, some improvements and modifications can also be made, and these im...

Abstract

The invention relates to a motor bearing installation protecting device of a nuclear power axial flow fan. The motor bearing installation protecting device of the nuclear power axial flow fan comprises a first assembling plate, a second assembling plate, a third assembling plate and an assembling tooling shaft. The first assembling plate, the second assembling plate and the third assembling plate are all formed through chamfering welding and assembling, the relative angle between every two neighboring assembling plates is 120 degrees, and the assembling tooling shaft is assembled in the axis of assembling plate assembling pieces and connected with the assembling plates through angle welding. Compared with the prior art, the motor bearing installation protecting device of the nuclear power axial flow fan solves the problem that, during the assembling process of an impeller and a motor, force stress is non-uniform and difficult to control and the impact force directly acts on the motor to result in undetectable damage to a motor bearing. The motor bearing installation protecting device of the nuclear power axial flow fan is reasonable in structure and convenient to use, protects the motor bearing, facilitates assembly and guarantees the assembling quality.

Description

technical field [0001] The invention relates to a nuclear power axial flow fan, in particular to a motor bearing installation protection device for a nuclear power axial flow fan. Background technique [0002] The assembly of the fan impeller and the motor is the core of the fan assembly, and the quality of the motor bearing determines the safe operation performance of the whole machine. The general impeller and motor assembly method is to install the impeller on the motor shaft by hammering (pressing method). Due to the uneven force during the pressing process, it is difficult to control the force, and the impact force directly acts on the motor, and it is easy to It causes damage to the motor bearing, which is difficult to find during the assembly process, which directly affects the safety performance and service life of the nuclear power fan in the later stage. Contents of the invention [0003] Purpose of the invention: In order to overcome the deficiencies of the pri...
