Abstract
The embodiment of the invention discloses a tilting pad bearing, which belongs to the technical field of a bearing. The bearing comprises a bearing seat and pad blocks, wherein oil grooves are arranged between the adjacent tiles, and oil dividing beams are arranged in the oil grooves. According to the embodiment of the invention, the oil dividing beams are arranged in the oil grooves of the adjacent pad blocks of the tilting pad bearing, high-temperature oil and low-temperature oil in the oil grooves are separated, lubricating oil of a tilting pad has the proper temperature, and the normal work performance of the lubricating oil and the dynamic characteristics of the tilting pad bearing are ensured.
Description
Technical field
The present invention relates to technical field of bearings, relate in particular to a kind of tilting-pad bearing.
Background technique
Along with machineries such as steam turbine, centrifugal compressor develop to high-speed, high-power direction day by day, the tilting-pad bearing with high stability is used more and more widely.Tilting-pad bearing has favorable damping property, not only has bigger bearing capacity, low power consumption, and simple in structure, maintenance convenience, by high-power, high-revolving machinery of modern times is adopted.Tilting-pad bearing is a kind of spring bearing of using always, is certain wedge gap to be set form the oil film rigidity of carrying use between tilting pad and running shaft.
An oil groove is arranged between the adjacent tile fragment of existing tilting-pad bearing; The cold oil that deep fat that flows out from tile fragment in the course of the work and the oil inlet hole from oil groove feed just gets into next tile fragment after mixing; Make the oily temperature rise that gets into tile fragment like this; Reduce oil body largely, greatly influenced the dynamic property of tilting-pad bearing, and then influenced the performance of unit.
Summary of the invention
In order to solve existing tilting-pad bearing since in the oil groove deep fat and cold oil mix and cause oil warm higher and then influence the problem of lubricant oil usability and tilting-pad bearing characteristic, the embodiment of the invention provides a kind of tilting-pad bearing.Said technological scheme is following:
The embodiment of the invention discloses a kind of tilting-pad bearing, said bearing comprises bearing support and tile fragment, is provided with oil groove between said adjacent tile fragment, wherein, is provided with Fen Youliang in the said oil groove.
Preferably, the oily beam of said branch is arranged in a side of oil groove oil inlet hole.
Preferably, the oily beam of said branch is located at the upper reaches of the oil inlet hole of axle journal sense of rotation in the bearing.
Preferably, said oil groove is divided into upstream side and downstream side two-part by the oily beam of said branch, and said upstream side and downstream side are separate.
Preferably, the oily beam cross section of said branch is a rectangle.
Compared with prior art; The beneficial effect of the embodiment of the invention is; Through the oily beam of branch is set in the oil groove of the adjacent tile fragment of tilting-pad bearing; High temperature oil in the oil groove and low temperature oil content are left, made the lubricant oil of tilting pad be in suitable temperature, guaranteed the normal working performance of lubricant oil and the dynamic property of tilting-pad bearing.

Fig. 4 is the tilting-pad bearing the other end general structure schematic representation that the embodiment of the invention provides.
Embodiment
For making the object of the invention, technological scheme and advantage clearer, will combine accompanying drawing that embodiment of the present invention is done to describe in detail further below.
The embodiment of the invention discloses a kind of tilting-pad bearing, as shown in Figure 1, this tilting-pad bearing includes bearing support and tile fragment 8; Bearing support is divided into upper bearing bracket 1 and step 2, and bearing support is fixing through bolt 3, and adjustment pad 5 is arranged between bolt 3 and bearing support; The bearing support side is provided with pin 6, and the bearing support end face has oil baffle 7, is provided with oil groove between adjacent tile fragment; Wherein, be provided with the oily beam 4 of branch in the oil groove.Divide oily beam 4 to be arranged in a side of oil groove oil inlet hole, and divide oily beam 4 to be located at the upper reaches of the oil inlet hole of axle journal sense of rotation in the bearing.Oil groove is divided into upstream side and downstream side two-part by a minute oily beam, and upstream side and downstream side are separate.Thereby make the high temperature grease that brings out through axle journal in the course of the work under bigger centrifugal action, be dumped into the deep fat side in the oil groove; Promptly divided the upstream side (deep fat side) of oily beam 4 separated oil grooves, and have only high temperature grease seldom to be brought into by minute downstream side of oily beam 4 separated oil grooves (cold oil side).Like this, be separated out, make the lubricating oil temperature that gets into next tilting pad be in suitable temperature, thereby greatly guaranteed the dynamic property parameter of tilting-pad bearing from tilting pad high temperature grease that comes out and the subzero oil that feeds bearing from oil inlet hole.Divide oily beam cross section to be preferably rectangle.
The embodiment of the invention is provided with the oily beam of branch through oil inlet hole one side in the oil groove of the adjacent tile fragment of tilting-pad bearing; Oil groove is divided into upstream side and downstream side two-part; High temperature oil and low temperature oil content are opened, both guaranteed that the lubricant oil of tilting pad is in suitable temperature, be in the good working performance state; Guarantee the dynamic property that tilting-pad bearing is good again, design and manufacturing are also very simple simultaneously.。
More than specific embodiment of the present invention is described in detail, but the present invention is not restricted to the specific embodiment of above description, it is just as example.To those skilled in the art, any being equal to
Revise and substitute also all among category of the present invention.Therefore, not breaking away from impartial conversion and the modification of having done under the spirit and scope of the present invention, all should contain within the scope of the invention.
