Abstract
The utility model relates to a tilting-type sliding bearing bush which consists of a plurality of sector bush blocks, wherein the inner diameter of the bush block is a section of the inner diameter of a bearing; and the back surface of the bush block is provided with an arc which ensures the bush block to be in linear contact with a bearing body after installation. The tilting-type sliding bearing bush is characterized in that the oil inlet side of the bush block is provided with a section of slope so as to form a wedge-shaped lubricating oil inlet with a rotor; and the length of the slope is 10-15% of the length of the radial stress section of the bush block and is in the rotating tangential direction of the rotor. The tilting-type sliding bearing bush has the beneficial effects that by adding the slope at the oil inlet side, the unit fault caused by fitting of the oil inlet side of the bush block and the rotor is prevented, thereby prolonging the service life.
Description
Technical field
The utility model relates to a kind of bearing shell, particularly relates to a kind of tilting-type plain bearing bush that is used for steam turbine.
Background technique
As everyone knows, the tilting-type plain bearing bush that is used for steam turbine is made up of some fan-shaped tile fragments usually, and the tile fragment internal diameter is a section of bearing bore diameter, and a circular arc is established at the tile fragment back side, makes itself and bearing support that the back is installed and contacts for line.This class bearing shell is when operation, and tile fragment can be adjusted oil slick thickness voluntarily, makes rotor operation more stable.Because tile fragment surface force in radial imbalance, the fit phenomenon of back braking of tile fragment oil-feed side and rotor can appear under abnormal conditions, make lubricant oil can't or the less tile fragment surface that enters, cause the bearing bush temperature rising, and unit can not normally be moved.
Summary of the invention
The utility model is the tilting-type plain bearing bush that a kind of long service life simple in structure is provided in order to address the above problem.
Scheme of the present utility model is achieved in that a kind of tilting-type plain bearing bush, is made up of some fan-shaped tile fragments.Wherein the tile fragment internal diameter is a section of bearing bore diameter, and a circular arc is established at the tile fragment back side, makes itself and bearing support that the back is installed and contacts for line; Establish one section slope in the oil-feed side of tile fragment, make itself and rotor form the lubricating oil inlet of wedge shape, slope length is the 10%-15% of tile fragment radial force section length, and on the tangent direction of rotor rotation.
The beneficial effects of the utility model are: by setting up oil-feed skew back slope, prevent the applying of invar piece oil-feed side and rotor and the situation appearance of initiation unit fault, thereby increase the service life.
Description of drawings
Fig. 1 is the structural representation of model utility.
Fig. 2 is the partial enlarged drawing among Fig. 1.
Among the figure: 1, bearing shell, 2, bearing support, 3, rotor, 4, oil film wedge.
Embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is further described:
Shown in Figure 2 as Fig. 1, when rotor 3 operations, bearing shell 1 is supported by bearing support 2, and tile fragment can be swung, and regulates oil slick thickness, makes unit operation stable.And when tile fragment oil-feed side with fit with rotor after owing to be provided with oil film wedge 4 in the oil-feed side, so rotor also can bring lubricant oil into the tile fragment surface, thereby prevents invar piece oil-feed side and rotor from fitting and cause the situation appearance of unit fault.
Claims (1)
1. tilting-type plain bearing bush, form by some fan-shaped tile fragments, wherein the tile fragment internal diameter is a section of bearing bore diameter, a circular arc is established at the tile fragment back side, make itself and bearing support that the back is installed and contact, it is characterized in that: establish one section slope in the oil-feed side of tile fragment, make itself and rotor form the lubricating oil inlet of wedge shape for line, slope length is the 10%-15% of tile fragment radial force section length, and on the tangent direction of rotor rotation.
