Abstract
The utility model relates to a motor bearing installation and protection device of a nuclear power axial flow fan. The motor bearing installation and protection device comprises a first assembly board, a second assembly board, a third assembly board and an assembly tool shaft. The first assembly board, the second assembly board and the third assembly board are formed through chamfering, welding and splicing. The relative angle among the assembly boards is 120 degrees. The assembly tool shaft and the assembly boards are in angle welding connection at the axis position of the spliced piece of the assembly boards. Compared with the prior art, the motor bearing installation and protection device solves the problems that in the assembly process of an impeller and a motor, exertion force is uneven, force is difficult to control, and due to the fact that impact force is directly exerted on the motor, a motor bearing is damaged easily and the damage is not easy to find. The motor bearing installation and protection device is reasonable in structure, convenient to use, and capable of protecting the motor bearing, facilitating assembly and ensuring assembling quality.
Description
Technical field
The utility model relates to a kind of nuclear power axial-flow blower, particularly a kind of motor bearings protection device for installing of nuclear power axial-flow blower.
Background technique
The assembling of draught fan impeller and motor is the core of blower fan assembling, and the quality of motor bearings is determining the safe running performance of complete machine.General impeller and motor assembly method all are that the method (plunging) with hammering is contained in impeller on the motor shaft, because it is firmly uneven in the process of press in, strength is difficult to control, and impact force acts directly on the motor, reach the damage that easily causes motor bearings, and be difficult in the assembly process find, directly influence Safety performance and the working life in nuclear power blower fan later stage.
The model utility content
The model utility purpose: in order to overcome the deficiencies in the prior art, it is a kind of rational in infrastructure, easy to operate that the utility model provides, and can effectively protect the motor bearings protection device for installing of the nuclear power axial-flow blower of motor bearings simultaneously.
The technical solution adopted in the utility model: for achieving the above object, the utility model adopts following technological scheme:
A kind of motor bearings protection device for installing of nuclear power axial-flow blower; comprise first assembled plate, second assembled plate, the 3rd assembled plate, assembly tool axle; described first assembled plate, second assembled plate, the 3rd assembled plate are assembled into type by the groove opening welding; relative angle between each assembled plate is 120 °, and fillet welding is connected described assembly tool axle with assembled plate at the shaft core position of assembled plate building block.
As optimization, all be lined with a jack on the described every assembled plate.
Beneficial effect: compared with prior art; the utility model has solved in the assembly process of impeller and motor; firmly uneven; strength is difficult to control, and impact force acts directly on the motor, and easily causes motor bearings to damage ND problem again; the motor bearings protective gear that provides is rational in infrastructure, easy to use; in the protection motor bearings, be beneficial to assembling again, guarantee assembly quality.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of use state of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
A kind of motor bearings protection device for installing of nuclear power axial-flow blower as shown in Figure 1, 2; comprise first assembled plate 1, second assembled plate 2, the 3rd assembled plate 3, assembly tool axle 4; first assembled plate 1, second assembled plate 2, the 3rd assembled plate 3 are assembled into type by the groove opening welding; relative angle between each assembled plate is 120 °; fillet welding is connected assembly tool axle 4 with assembled plate at the shaft core position of assembled plate building block, all is lined with a jack 5 on the every assembled plate.
The above only is preferred implementation of the present utility model; be noted that for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
