Description
Technical field
The utility model relates to a kind of oil guard, specially a kind of steam turbine oil guard.
Background technique
Currently, existing steam turbine generallys use the tooth-like oil scraper ring of sealing to prevent lubricating oil from leaking outside, however, when steam turbine exists
When starting or shutting down critical speed, Steam Turbine Vibration is larger, and sealing tooth is easy to happen abrasion, causes to seal between tooth and rotor
Gap increases, the gear oil ability decline of oil scraper ring, and in addition to this, when steam turbine unstable state revolving speed, the track of rotor rotation is not
Circular, this causes rotor and sealing tooth to touch mill, and the gap destructiveness for sealing tooth and rotor increases, and serious leakage occurs
Oil, it is above-mentioned in order to solve the problems, such as, therefore, it is proposed that a kind of steam turbine oil guard.
Utility model content
The purpose of this utility model is to provide a kind of steam turbine oil guards, pass through the gear oilcan of turntable back side simultaneously
Circle and the state that formation fits at mesopore, largely avoided the machine oil inside turbine body and leak, solve back
The problem of proposed in scape technology.
To achieve the above object, the utility model provides the following technical solutions: a kind of steam turbine oil guard, including vapour
Turbine ontology and baffle, the surface of the turbine body offers mesopore, and the inside of mesopore is equipped with rotation axis, institute
The inside for stating baffle offers dish groove, and the inside of dish groove is equipped with turntable, and axis hole, and axis are offered at the center of the turntable
The inner wall in hole is equipped with rubber ring, and the back side of the turntable is equipped with gear oilcan circle.
As a kind of preferred embodiment of the utility model, the quadrangle of the baffle offers hollow hole, and hollow
The inside in hole is placed with the bolt to match with hollow hole.
As a kind of preferred embodiment of the utility model, the bolt is connect by hollow hole with threaded hole.
As a kind of preferred embodiment of the utility model, the rubber ring installed inside the axis hole and rotation axis it is outer
Wall fits.
As a kind of preferred embodiment of the utility model, the outer ring of the gear oilcan circle and the inner ring of mesopore are affixed
It closes.
Compared with prior art, the beneficial effects of the utility model are as follows:
A kind of steam turbine oil guard of the utility model:
1. forming the state to fit at the gear oilcan circle and mesopore by turntable back side simultaneously, steamer largely avoided
The lubricating oil of machine body interior leaks.
2. preferable palette effect can be played with rotation axis by installing rubber ring by shaft hole inner wall, can be to avoid profit
Lubricating oil is overflowed by rotation axis.

Specific embodiment
To be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, below
In conjunction with specific embodiment, the utility model is further described.
Fig. 1-5 is please referred to, the utility model provides a kind of technical solution: a kind of steam turbine oil guard, including steamer
Machine ontology 1 and baffle 2, the surface of the turbine body 1 offers mesopore 9, and the inside of mesopore 9 is equipped with rotation axis
10, the inside of the baffle 2 offers dish groove 4, and the inside of dish groove 4 is equipped with turntable 5, opens up at the center of the turntable 5
There is axis hole 6, and the inner wall of axis hole 6 is equipped with rubber ring 7, the back side of the turntable 5 is equipped with gear oilcan circle 11.
As shown in Figure 1, being affixed by being formed at the gear oilcan circle 11 and mesopore 9 of 5 back side of turntable simultaneously in the present embodiment
The state of conjunction largely avoided the lubricating oil inside turbine body 1 and leak.
