Abstract
The invention discloses an annular oil passage pivoted pad bearing. An adjusting block is added on the top circle of the pivoted pad bearing; the pivoted pad bearing is provided with an annular oil passage. The oil inlet of each pad is communicated with the annular oil passage. The invention has the advantages that: the height of a spindle system can be adjusted conveniently when in maintenance; the annular oil passage can be designed conveniently; the structure of the pad is used on a rational basis; the problem of feeding oil to the bearing is solved; and the complete bearing structure is compact.
Description
Technical field
The invention belongs to high speed rotor rotated supporting parts such as the chemical industry equipment of large-scale thermal power equipment, high speed rotating and industrial small turbine.
Background technique
The tilting-pad bearing of jet-type fuel feeding; the design of its fuel feeding oil duct is generally bearing top circle does not have the adjustment cushion block; oil duct is encapsulated in (see figure 1) between bearing support and the bearing top circle; when the shutdown maintenance needs to adjust the bearing absolute altitude behind the equipment operation one-period; must realize adjusting the bearing support bottom by lifting bearing housing, make troubles to maintenance.
Summary of the invention
The objective of the invention is to solve the drawback that above-mentioned prior art is brought to maintenance, for the convenience axle is the adjustment of absolute altitude and solves the problem of bearing oil-feed, and design a kind of tilting-pad bearing of open loop shape oil duct, and the oil inlet hole and the ring shaped oil passage of each tile fragment got through, the oil-feed problem and the absolute altitude that have fundamentally solved bearing are adjusted problem.
The objective of the invention is such realization: set up the adjustment cushion block on the cylindrical of tilting-pad bearing, ring shaped oil passage is set, the oil inlet hole with each tile fragment is communicated with ring shaped oil passage again.
Described spacer number of blocks is corresponding with tile fragment.
Useful good effect of the present invention is: having made things convenient for when maintenance axle is the adjustment of absolute altitude, the design of ring shaped oil passage, reasonable use the structure of bearing shell body, solved the problem of bearing oil-feed, make whole bearing structure compactness.

Embodiment
With reference to Fig. 2-Fig. 5, on the cylindrical of tilting-pad bearing, set up and adjust cushion block 1, ring shaped oil passage 7 is set, the filler opening 12 of each tile fragment 3 is communicated with ring shaped oil passage 7.Earlier tile fragment 3 is located in during assembling bearing support first 2 and second are on 13, load onto the fixed-site of oil seal ring 10 with tile fragment 3, with the locating stud 11 of oil seal ring 10 and bearing support and attachment screw 9 oil seal ring 10 is fixed on the bearing support on second again, second is put on the bearing support with bearing support, check to adjust the situation that contacts of cushion block 1 and bearing support, after treating that area of contact reaches designing requirement, close again bearing support first, with on the bearing support second attachment screw and locating stud 4,5 with bearing support semidefinite position and up and down tight.
Claims (2)
1. ring shaped oil passage type tilting pad bearing, it is characterized in that: the adjustment cushion block is circumferentially set up in the cylindrical upper edge at tilting-pad bearing.
2. ring shaped oil passage type tilting pad bearing as claimed in claim 1 is characterized in that: be provided with ring shaped oil passage on the bearing support of tilting-pad bearing, the filler opening of each tile fragment is communicated with ring shaped oil passage.
