Description
Technical field
It the utility model is related to a kind of fixture, and in particular to the fixture for being easy to steam turbine air chamber both ends to assemble.
Background technology
Steam turbine is the rotary power machinery that the energy conversion of steam is turned 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
Meet production and heat supply needs in life using the steam discharge of steam turbine or intermediate extraction.Steam turbine enters the steam from boiler
After entering steam turbine, successively by 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 by different way in steam turbine, just constitutes the steamer of different operating principle
Machine.
Bearing is a kind of important spare part in contemporary plant equipment, and its major function is the mechanical rotary body of support, is reduced
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 typically 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,
