Description
Technical field
The present invention relates to a kind of fixture, and in particular to steam turbine cylinder air chamber end mounting component frock.
Background technology
Steam turbine is the rotary power machinery that the energy of steam is converted into mechanical work, also known as steam turbine.Steamer
Machine is mainly used as prime mover of generating, can also directly drive various pumps, blower fan, compressor and propeller for vessels etc., can be with
Production and heat supply needs in life are met using the steam discharge of steam turbine or intermediate extraction.Steam turbine enters the steam from boiler
Enter after steam turbine, sequentially pass through the nozzle and movable vane of a series of loop configurations, the heat energy of steam is converted into turbine rotor rotation
The mechanical energy turned.Steam carries out energy conversion, just constitutes the steamer of different operating principle by different way in steam turbine
Machine.
Bearing is a kind of important spare part in contemporary plant equipment, and its major function is the mechanical rotary body of support, reduction
Coefficient of friction in its motion process, and ensure its rotating accuracy.By the difference of motor element frictional property, bearing can be divided into rolling
Dynamic bearing and the major class of sliding bearing two.Wherein rolling bearing is normalized, seriation, but its radial direction compared with sliding bearing
Size, vibration and noise are larger, and price is also higher.Rolling bearing is general by outer ring, inner ring, rolling element and the part group of retainer four
Into.By the shape of rolling element, rolling bearing is divided into ball bearing and the major class of roller bearing two.When rotor is arranged in cylinder body,
The lifting rope on boatswain chair is put in the rotating shaft of two ends of rotor, then by mobile boatswain chair of driving a vehicle, and mobile and lifting hanger
Plate, rotor is placed in the correct position of cylinder body.
When rotor is arranged in cylinder body, bearing need to be arranged in the rotating shaft of two ends of rotor, to increase the flatness of rotation,
And avoid rotating abrasion.The installation site of bearing is located at the two ends at the two ends, i.e. rotor of steam turbine air chamber.Bearing turns on being arranged
The period of the day from 11 p.m. to 1 a.m to it, it is necessary to be cleaned, it is to avoid the impurity such as dust iron filings is sticked on bearing, influence the stationarity of transmission.
When bearing is set in into steam turbine air chamber two ends, need first clean bearing there is provided air chamber two ends, bearing and
The stability of rotor engagement, it is to avoid stuck foreign matter on bearing, the stationarity that influence rotor is rotated.
Then traditional bearing cleaning sprays the cleaning agents such as machine oil for bearing is put into cleaning inframe, carries out high-pressure wash.
This cleaning way not only can not be clean by bearing cleaning, and when being rocked in cleaning, bearing can be made impinging one another, produces indenture,
The stationarity for influenceing it to be driven.If artificial hand holds bearing to be cleaned, although bearing can be rotated at random, so that bearing
Cleaned liquid cleaning, but which increase labor strength, and rotor bearing radius greatly, workman is difficult free-hand to pick up quality
Excessive bearing.
The content of the invention
Present invention aims at steam turbine cylinder air chamber end mounting component frock is provided, traditional bearing cleaning is solved
Not only can not be clean by bearing cleaning, and when being rocked in cleaning, bearing can be made impinging one another, produce indenture；And artificial hand is held
