Abstract
The utility model relates to an assembling tool of a large-scale motor fan with keyless connection, which is used for assembling a fan blade on a motor rotor. The assembling tool of a large-scale motor fan with keyless connection is characterized by comprising a hydraulic nut and a position sleeve; the hydraulic nut is sleeved on a motor rotor and disposed outside a fan blade; if high pressure hydraulic oil is accessed to the hydraulic nut, the outer side of the fan blade is pressed by a piston in the hydraulic nut; the position sleeve is fixedly arranged on the motor rotor in a detachable manner and arranged outside the hydraulic nut, and the hydraulic nut is supported by the position sleeve; the wheel hub of the fan blade is provided with an oil hole that penetrates to the inner taper hole of the fan blade in a radial manner; and the high pressure hydraulic oil can enter between the inner taper hole of the fan blade and the motor rotor via the oil hole. The assembling tool of a large-scale motor fan with keyless connection is simple in structure, easy in operation, convenient in mounting and dismounting, allows workpieces not to deform for dismounting, and can be mounted and dismounted repeatedly for many times. Moreover, no heating is needed for mounting, and pressing force and expansion force are provided simply through the high pressure hydraulic oil.
Description
Technical field
The utility model belongs to the motor manufacturing technology field, and specifically relating to a kind of large-size machine fan does not have the assembly tool that key connects.
Background technology
For large-size machine; The electric motor fan parts that are absolutely necessary, the installation of electric motor fan is an important step preface, the assembly method of traditional large-size machine fan is that electric motor fan is heated to uniform temperature; Overlap then to rotor, treat that its cooling back is fixing automatically.This assembly technology more complicated, owing to be the hot jacket form, dismounting is very inconvenient, sometimes even parts are deformed, causes whole parts to scrap, production cost is high, assembly quality and inefficiency.
Summary of the invention
The purpose of the utility model is to overcome the deficiency that exists in the prior art; Provide a kind of large-size machine fan not have the assembly tool that key connects, it is simple in structure, processing ease; Need not heat during installation, as long as pressure and tension are provided through feeding high-pressure and hydraulic oil; Easy installation and removal, the workpiece dismounting is indeformable, but the repeated multiple times mounting or dismounting.
The technical scheme that provides according to the utility model: the large-size machine fan does not have the assembly tool that key connects; Be used for fan blade is assemblied in rotor; It is characterized in that: said assembly tool comprises hydraulic nut and positioning sleeve, and said hydraulic nut is enclosed within on the rotor, and is arranged on the fan blade outside; When hydraulic nut inserts high-pressure and hydraulic oil, the piston roof pressure fan blade lateral surface in the hydraulic nut; Said positioning sleeve fixedly is assemblied on the rotor removably, and positioning sleeve is arranged on the hydraulic nut outside, and withstands hydraulic nut; The wheel hub of said fan blade is provided with the oilhole that radially is through to the fan blade internal taper hole, and high-pressure and hydraulic oil can get between fan blade internal taper hole and the rotor from this oilhole.
The utility model compared with prior art, advantage is: the utility model is simple in structure, processing ease need not heat during installation, as long as through feeding high-pressure and hydraulic oil pressure and tension are provided; Easy installation and removal, the workpiece dismounting is indeformable, but the repeated multiple times mounting or dismounting; The utility model is installed by axle connection, the shaft joint of electromechanics trade and the belt pulley installation all is an effective choice, and the scope of application is extensive.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with concrete accompanying drawing and embodiment the utility model is described further.
As shown in Figure 1; The assembly tool that said large-size machine fan does not have the key connection is used for fan blade 3 is assemblied in rotor 4; It mainly is made up of hydraulic nut 2 and positioning sleeve 1, and said hydraulic nut 2 is enclosed within on the rotor 4, and is arranged on fan blade 3 outsides; When hydraulic nut 2 inserts high-pressure and hydraulic oil, piston roof pressure fan blade 3 lateral surfaces in the hydraulic nut 2; Said positioning sleeve 1 fixedly is assemblied on the rotor 4 removably, and positioning sleeve 1 is arranged on hydraulic nut 2 outsides, and withstands hydraulic nut 2; The wheel hub of said fan blade 3 is provided with the oilhole 5 that radially is through to fan blade 3 internal taper holes, and high-pressure and hydraulic oil can get between fan blade 3 internal taper holes and the rotor 4 from this oilhole 5.
Utilize the installation process of this assembly tool assembling fan following:
1, fan blade 3 internal taper holes is cleaned up, then fan blade 3 is sleeved on the rotor 4;
2, with hydraulic nut 2 on rotor 4, hydraulic nut 2 is arranged on fan blade 3 outsides, loads onto positioning sleeve 1 then, makes positioning sleeve 1 block hydraulic nut 2;
3, the oilhole on fan blade 3 wheel hubs 5 feeds high-pressure and hydraulic oil, makes expanding and the pressurize under the pressure of high-pressure and hydraulic oil of fan blade 3 internal taper holes;
4, hydraulic nut 2 feeds high-pressure and hydraulic oil; Make the piston roof pressure fan blade 3 in the hydraulic nut 2; Fan blade 3 moves to directions X under the effect of hydraulic nut 2, and the displacement of fan blade 3 detects through amesdial 6, after waiting to be pressed onto the position of regulation requirement; Oilhole 5 and hydraulic nut 2 releases on fan blade 3 wheel hubs, fan blade 3 hug through fan blade 3 internal taper holes and realize that on motor shaft no key connects;
5, unload positioning sleeve 1 and hydraulic nut 2, accomplish assembling.
This assembly tool is installed by axle connection, the shaft joint of electromechanics trade and the belt pulley installation all is an effective choice, and the scope of application is more extensive.
