Abstract
The utility model discloses a thrust shoe and bearing frame connection structure, a plurality of thrust shoes of realizing including the bearing frame and in locating the bearing frame, the circle is equipped with the dovetail along circumference in the bearing frame, thrust shoe back excircle is equipped with outstanding dovetail block, dovetail block installs in the dovetail. The utility model discloses adopt dovetail block and dovetail complex structure between thrust shoe and bearing frame, when consequently needing to be changed the thrust shoe, just can be according to the dovetail block at the thrust shoe back as long as open the bearing frame, along dovetail roll -off thrust shoe on the bearing frame, greatly reduced the work load of change thrust shoe, greatly made things convenient for the change of thrust shoe.
Description
Technical field
The utility model relates to bearing, is specifically related to thrust pad bearing.
Background technique
In use, because the external force change be subject to rises and falls greatly, easily cause tile kilning phenomenon, existing structure just must take bearing support apart to thrust-bearing, rotor of slinging, and then whole dish thrust pad could be taken out and change.
Model utility content
Technical problem to be solved in the utility model is just to provide a kind of thrust pad and bearing support linkage structure, is convenient to the replacing of thrust pad.
For solving the problems of the technologies described above, the utility model adopts following technological scheme: a kind of thrust pad and bearing support linkage structure, comprise bearing support and be located at the some thrust pads in bearing support inner circle, described bearing support inner circle is circumferentially provided with dovetail groove, described thrust pad back cylindrical is provided with outstanding dovetails, and described dovetails is installed in dovetail groove.
Preferably, described thrust pad comprises thrust pad body and is located at the babbit layer of thrust pad body internal circular surfaces.
The structure that the utility model adopts dovetails to coordinate with dovetail groove between thrust pad with bearing support, when therefore needing to change thrust pad, just can according to the dovetails at the thrust pad back side as long as open bearing support, bearing support skids off thrust pad along dovetail groove, greatly reduce the workload changing thrust pad, greatly facilitate the replacing of thrust pad.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is further described:
Fig. 1 is the structural representation of the radial section of bearing support;
Fig. 2 is the structural representation of the radial section of thrust pad;
Fig. 3 is the linkage structure schematic diagram of thrust pad and bearing support.
Embodiment
As shown in Figure 1 to Figure 3, a kind of thrust pad and bearing support linkage structure, comprise bearing support 1 and be located at the some thrust pads 2 in bearing support inner circle, described bearing support inner circle is circumferentially provided with dovetail groove 11, described thrust pad back cylindrical is provided with outstanding dovetails 21, and described dovetails is installed in dovetail groove.Described thrust pad 2 comprises thrust pad body and is located at the babbit layer 22 of thrust pad body internal circular surfaces.
Due to the structure adopting dovetails to coordinate with dovetail groove between thrust pad with bearing support, when therefore needing to change thrust pad, just can according to the dovetails at the thrust pad back side as long as open bearing support, bearing support skids off thrust pad along dovetail groove, greatly reduce the workload changing thrust pad, greatly facilitate the replacing of thrust pad.
Further, as shown in Figure 3, described dovetail groove 11 inner circle is provided with flat mat 12, and described dovetails 21 cylindrical is provided with sphere rigid support block 22, and the sphere of described sphere rigid support block coordinates with the plane of flat mat.
When the rotor is turning, the change of the Impact direction that external force produces along with the rotation of rotor, axial force is delivered to sphere rigid support block by thrust pad, pass through sphere-contact, the loading angle of automatic adjustment thrust pad, keep the planeness of whole dish tile fragment, thus make to keep the axial position of rotor constant.
Claims (2)
1. a thrust pad and bearing support linkage structure, comprise bearing support and be located at the some thrust pads in bearing support inner circle, it is characterized in that: described bearing support inner circle is circumferentially provided with dovetail groove, described thrust pad back cylindrical is provided with outstanding dovetails, and described dovetails is installed in dovetail groove.
2. a kind of thrust pad according to claim 1 and bearing support linkage structure, is characterized in that: described thrust pad comprises thrust pad body and is located at the babbit layer of thrust pad body internal circular surfaces.
