Abstract
The utility model relates to a tubular-flow-typed turbine main-shaft protection hood, which comprises a protection hood body, and is characterized in that the protection hood body is divided into a protection hood I and a protection hood II, wherein, the protection I holds the protection II through a bolt; a gap is arranged at the bolt junction position; a sealing strip is arranged at the junction position of the protection I and the protection II; the inner side of the protection II is provided with a L-shaped steel plate; the steel plate is connected with the protection hood and is provided with an oil-throwing ring; the steel plate , the oil-throwing ring, the steel plate and a bearing seat that is connected with the protection hood form a sealing hollow cavity; therefore, the protection hood has simple structure and good sealing effect, and is convenient to be installed and disassembled.
Description
Technical field
The utility model belongs to water turbine and makes the field, particularly relates to a kind of good seal performance, tubular turbine main shaft guard shield simple in structure.
Background technique
Make the field at water turbine; main shaft is most important transmission part; reliability for main shaft is worked when unit turns round generally is equipped with the main shaft guard shield in the outside of main shaft and protects main shaft, and its problem that mainly solves is to prevent from the fluid of unit to influence the working life of main shaft.Existing tubular turbine main shaft guard shield is generally integral type, whole main shaft guard shield is sleeved on the main shaft outside, the main shaft guard shield is fixed by flange coupling shaft bearing, between flange ring and main shaft guard shield, be shaped on a rubber bar and play seal action, when unit turns round, because the vibration of unit, also vibration thereupon between main shaft guard shield and the bearing support, at this moment the rubber bar just can not well play sealing effect, cause leakage of oil, influence the working life of main shaft, more even can cause great economic loss to the power station, the said structure volume is bigger in addition, the installing/dismounting inconvenience.
Summary of the invention
The utility model provides a kind of good seal performance, tubular turbine main shaft guard shield simple in structure for solving the technical problem that exists in the known technology.
The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of tubular turbine main shaft guard shield, comprise shroud body, it is characterized in that: described shroud body is divided into two sections guard shield I and guard shield II, guard shield I connects guard shield II, the junction is provided with Stamping Steel Ribbon, the inboard of guard shield II is provided with steel plate, and steel plate connects in the guard shield and is provided with disc, steel plate and disc and the sealed cavity of bearing support formation that links to each other with guard shield.
The utility model can also adopt following technical measures:
Described guard shield I and guard shield II closing, leave gap in the bolt joint by bolt.
The steel plate that the inboard of described guard shield II is provided with is made as L shaped.
Advantage and the good effect that the utlity model has are: because the main shaft guard shield is divided into two sections guard shield I and guard shield II, two guard shields close by the bolt handle, the joint is provided with Stamping Steel Ribbon, leave the installation side quick-mounting in the bolt joint and put the gap, the inboard of guard shield II is provided with L shaped steel plate, the disc that is provided with in L shaped steel plate and the guard shield links to each other, L steel plate and disc and the bearing support that links to each other with guard shield constitute a sealed cavity like this, prevent that effectively fluid from entering the working life that main shaft influences main shaft, and have the function of temporary fluid, be convenient to fluid and discharge along oil exit pipe.So said structure is simple, good sealing effect, and be convenient to installation and removal.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Among the figure: 1, shroud body; 1-1, guard shield I; 1-2, guard shield II; 2, bolt; 3, Stamping Steel Ribbon; 4, L shaped steel plate; 5, disc; 6, bearing support; 7, gap.
Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, shroud body 1 is divided into two sections guard shield I1-1 and guard shield II1-2, two guard shields close by 2 on bolt, the joint is provided with Stamping Steel Ribbon 3, leave the installation side quick-mounting in bolt 2 joints and put gap 7, be provided with L shaped steel plate 4 in the inboard of guard shield II, the disc 5 that is provided with in L shaped steel plate 4 and the guard shield links to each other, L steel plate 4 and disc 5 and the bearing support 6 that links to each other with guard shield constitute a sealed cavity like this, prevented that effectively fluid from entering main shaft, and the function with temporary fluid is convenient to fluid and is discharged along oil exit pipe.
