Abstract
An adjustable eccentric tilting pad is characterized in that the back of the tilting pad is provided with a radial-clearance adjustable spacer, two sides of the lower portion of the tilting pad are respectively eccentrically provided with an outlet oil wedge and an inlet oil wedge, the corresponding radian between the outlet oil wedge and the central line of the tilting pad is a, the radian of the tilting pad block is b, the ratio of the a to the b ranges from 0.40 to 0.46, and a transition oil wedge ranging from 0 mm to 0.3 mm is arranged on the inlet oil wedge. The adjustable eccentric tilting pad effectively solves problems that clearance of an oil film of a bearing of a compressor is unreasonable, reduces vibration value of the compressor, is simple in structure, easier in process and obvious in economic benefit, and is suitable for application in aspects of tilting pad bearings of various axial rotary machines.
Description
Technical field
The utility model relates to a kind of adjustable off-centre watt tile fragment that can incline.
Background technique
As shown in Figure 1, existing five pieces watts of bearing tiles that can incline have a lot of shortcomings, and can the incline oil film wedge 5,6 of watt tile fragment about 3 of tradition is regardless of the import and export oil film wedge, watt tile fragment 3 backs of can inclining are provided with and bearing support fixed hole 4,1 is the axle center among Fig. 1, and 2 is bearing tile endoporus center, and 7 is axle.Adjust radial clearance and have only by machining accuracy and guarantee, non-adjustable, if reaching requirement, machining accuracy do not need manual scrape watt, cause the brearing bore roughness low like this, and do not reach desirable oil film oil film wedge molded lines.
The model utility content
The utility model purpose is to provide a kind of adjustable off-centre simple and reasonable for structure watt tile fragment that can incline.
To achieve these goals, the utility model adopts following technological scheme: the adjustable off-centre watt tile fragment that can incline, can the incline back of watt tile fragment is provided with the adjustable shims of can regulate radial clearance, can incline watt both sides, tile fragment bottom respectively off-centre outlet oil film wedge and import oil film wedge are set.
The described outlet oil film wedge and the corresponding radian that can incline between watt tile fragment center line are a, and the radian of watt tile fragment that can incline is b, and then the ratio of a and b is 0.40～0.46.
Described import oil film wedge place is provided with the transition oil film wedge of 0～0.3mm.
The utility model has solved the irrational problem of bearing of compressor oil clearance well, and the vibration values of compressor is reduced, and is simple in structure, easier processing, and remarkable in economical benefits is applicable to the application of all kinds of axial rotating machinery tilting-pad bearings aspect.
Description of drawings
Fig. 1 is the prior art constructions schematic representation;
Fig. 2 is a structural representation of the present utility model;
Fig. 3 is the A place structure for amplifying schematic representation of Fig. 2.
Embodiment
Embodiment: shown in Fig. 2,3,1 is the axle center, and 2 is bearing tile endoporus center, the adjustable off-centre watt tile fragment that can incline, can the incline back of watt tile fragment 3 is provided with the adjustable shims 10 of can regulate radial clearance, and is easy for installation like this, do not need manual scrape watt in installation process.Can incline both sides, watt tile fragment 3 bottom respectively off-centre outlet oil film wedge 8 and import oil film wedge 9 are set.The outlet oil film wedge 8 and the corresponding radian that can incline between watt tile fragment 3 center lines are a, the radian of watt tile fragment 3 of can inclining is b, then the ratio of a and b is 0.40～0.46, this structure makes import oil film wedge 9 bigger than outlet oil film wedge 8, the oil film wedge of import simultaneously 9 places are provided with the transition oil film wedge of c=0～0.3mm, and it is more reasonable that oil film is distributed.
Claims (3)
