Description
Technical field
The present invention relates to a kind of method of little air-gap generator motor assembling, can solve and install difficult problems such as installing generator amature under the very little limitation state of air gap reposefully, belong to and install the generator amature technical field.
Background technology
Generator amature installs common employing and place arc skateboard in stator core, and rotor is shelved on the arc skateboard by Journal bracket, and the pull rotor is dragged in an end holder, and the end rotor of slinging slowly penetrates rotor in the generator core.
There is one deck to approach sleeve between evaporated cooling electric machine rotor and the iron core, thin sleeve can bear rotor weight unlike iron core, so can not utilize arc skateboard to install rotor, and install air gap and be reduced to 24mm (traditional air gap that installs is 49mm), so evaporated cooling electric machine installs rotor and can not adopt traditional mode that installs promptly to utilize arc skateboard to install generator amature.
Summary of the invention
The purpose of this invention is to provide a kind of method that under the spatial limitation condition, can install generator amature safety and steady.
In order to realize above purpose, technical scheme of the present invention provides a kind of method of little air-gap generator motor assembling, it is characterized in that, concrete steps are:
The first step, guide rail is fixed, dolly is set on guide rail, at the guide rail bearing of trend sleeve is set, sleeve for encouraging end, is a vapour end away from guide rail one end near guide rail one end;
Second step, will encourage the end bearing seat and hang on the rotor, the generator shaft coupling will be installed on the rotor, and install on the generator shaft coupling and connect axle, with crane lifting rope lifting rotor to the guide rail top;
The 3rd goes on foot, rotor is placed on the dolly, and dolly drags rotor and penetrates in the sleeve;
The 4th step, stretch out the back from sleeve vapour end and hang with the crane lifting rope and connect axle when connecing axle, the end bearing seat is encouraged in dismounting, and dolly is withdrawn into rotor bearing shelves place, holds rotor and carriage is fixed on the dolly with carriage;
The 5th step, dolly drag rotor and move ahead, and live back segment at the vapour end with the cushion block pad and connect axle, leading portion is connect axle pull down, and the Using such method segmentation is pulled down three sections and connect axle;
The 6th step, remove dolly and guide rail, will encourage the end bearing seat and hang on the rotor, it is in place to lift rotors with two crane lifting ropes.
Utilization of the present invention connects axle and frocks such as dolly install generator amature, can reposefully rotor be penetrated in the sleeve under the spatial limitation condition, and it is more reliable and secure to install method than tradition.
Advantage of the present invention is practical, can reduce labor intensity, and strengthens coefficient of safety, increases work efficiency, and provides reliable foundation for solving a similar difficult problem, has promotional value.

Embodiment
The invention will be further described below in conjunction with drawings and Examples.
Embodiment
As shown in Figure 1, for installing generator amature frock schematic diagram, the described generator amature frock that installs is by connecing axle 1, guide rail 2, dolly 3, carriage 4, encouraging end bearing seat 5, cushion block 6, crane lifting rope 7, sleeve 8, generator shaft coupling 9, rotor bearing shelves 10, rotor 11, vapour end bearing seat 12 and steam turbine shaft coupling 13 and form.Connect axle 1 and is made up of at least three sections detachable short joint-shafts, it is connected on the rotor generator shaft coupling 9 by bolt, and its effect is rotor 11 to be prolonged so that connect spool 1 when rotor can hang when the vapour end stretches out; Dolly 3 can carry rotor 11 reposefully and slowly advance on guide rail 2; When dolly 3 drags rotor 11 at generator amature bearing shelves 10 places, need fill up on dolly 3, and firmly rotor 11 is bundled on the dolly 3 with hoop with carriage 4; Encouraging that end bearing seat 5 hangs on the rotor 11 is for counterweight, makes rotor 11 centers of gravity in rotor 11 centers; Remove when connecing axle 1 when segmentation, need to remove leading portion then and connect axle 1 with cushion block 6 support rotor 11.
Use the method for above-mentioned frock little air-gap generator motor assembling, concrete steps are:
The first step, guide rail 2 is fixing is provided with dolly 3 on guide rail 2, at guide rail 2 bearing of trends sleeve 8 is set, and sleeve 8 for encouraging end, is a vapour end away from guide rail 2 one ends near guide rail 2 one ends, carries out protection with crane lifting rope 7 contact position rotors 11 surfaces;
Second step, as shown in Figure 2, will encourage end bearing seat 5 and hang on the rotor 11, generator shaft coupling 9 is installed on the rotor 11, install on the generator shaft coupling 9 and connect axle 1, with crane lifting rope 7 lifting rotors 11 to guide rail 2 tops;
The 3rd the step, as shown in Figure 3, rotor is placed on the dolly 3, dolly 3 drags rotor 11 and penetrates in the sleeve 8;
The 4th step, as shown in Figure 4, to stretch out the back from sleeve 8 vapour ends and hang with crane lifting rope 7 and connect spool 1 when connecing axle 1, end bearing seat 5 is encouraged in dismounting, and dolly 3 is withdrawn into rotor bearing shelves 10 places, holds rotor and carriage 4 is fixed on the dolly 3 with carriage 4;
