Description
Technical field：
The utility model is related to a kind of end caps, and in particular to a kind of bearing box of steam turbine end cover structure.
Background technology：
Bearing box of steam turbine end cap is used for bearing housing end, plays a protective role to the bearing in bearing housing, and to bearing
Case is sealed, and prevents the lubricating oil in bearing housing from revealing.So it is very necessary to design a kind of bearing box of steam turbine end cover structure
's.
Utility model content：
In place of the utility model makes up and improve above-mentioned the deficiencies in the prior art, pass through such bearing box of steam turbine end cap
Structure can both realize that steam turbine measured axial displacement, and takes into account steam turbine speed measuring function, simple in structure, reasonable design, cost
It is cheap, it can promote and use on a large scale.
The technical solution adopted in the utility model is：A kind of bearing box of steam turbine end cover structure, the end cover structure are equipped with
The flange connecting hole of circumference uniform distribution, be respectively equipped with above and below end cap central bore micrometer threaded mounting hole and testing the speed pump into
Oily device threaded mounting hole.
The end cover structure is tightly connected with bearing box end cap.
The end cover structure is arch design.
The ring flange of the end cover structure is equipped with temperature sensor fixing hole.
The beneficial effects of the utility model：Simple in structure, reasonable design is of low cost, is easy to promote on a large scale and make
With.Realizing original function, while realize turbine shaft to displacement measurement, and take into account steam turbine speed measuring function.
Description of the drawings：
Fig. 1 is the structure diagram of the utility model.
Fig. 2 is the sectional view of the utility model.
Fig. 3 is the scheme of installation of the utility model.
Specific embodiment：
With reference to each figure, a kind of bearing box of steam turbine end cover structure, the end cover structure is equipped with the flanged joint of circumference uniform distribution
Hole, micrometer threaded mounting hole is respectively equipped with above and below end cap central bore and the pump oil feeding device threaded mounting hole that tests the speed；
The end cover structure is tightly connected with bearing box end cap；The end cover structure is arch design；The ring flange of the end cover structure is equipped with
Temperature sensor fixing hole.
By the lubricating oil on bearing body at trepanning extraction bearing minimum oil film, the oil temperature of extraction is measured, it can be objective
Reflect the maximum temperature of bearing.The mounting temperature sensor on bearing housing realizes the separation of temperature transducer and bearing.It can be true
Reflect bearing temperature, while the Quick universal of temperature transducer can be completed in the case where not dismantling bearing in fact.
Bearing housing end is fixed on by flanged joint, to the bearing in bearing housing and lubricating oil starting protection and the work of sealing
With.Corresponding equipment is installed to realize measurement rotor axial displacement by two threaded holes at bearing box end cap center, passes through end
The threaded hole of lid downside installs corresponding equipment and has taken into account steam turbine speed measuring function.
As shown in figure 3, bearing box end cap 1 is connected by flange bolt with bearing housing end, seal in bearing housing
Lubricating oil.It realizes by installing axial displacement device 3 and micrometer 2 on bearing box end cap and measures rotor axial displacement, by suitable
Sleeve arrangement in hour hands and axial rotary displacement device counterclockwise is pushed and is pulled to rotor, and axis can be read by micrometer 2
To displacement data；Lubricating oil is realized by the pump oil feeding device 4 that tests the speed to enter in speed measuring device by bearing box end cap 1, is realized
Pass through the speed-measuring method of bearing box end cap 1.
