Abstract
A quick dismounting device for an oil seal bushing of a turbine bearing seat of a gas turbine. Because the influence of the seal ring on the excircle of the oil seal bush and the deformation possibly generated after long-term operation, the oil seal bush is not easy to be detached. The utility model discloses the constitution includes: the fixed circular plate (4), the circumference of fixed circular plate on be provided with a set of stand (3), fixed circular plate inside be provided with a support cylinder section of thick bamboo (2), the stand pass the round hole of a support cylinder section of thick bamboo side, support board (5) of fixed circular plate both sides on be fixed with hydraulic jack (6) through the bolt, hydraulic jack upper portion with floor (1) fixed connection of a support cylinder section of thick bamboo side, a support cylinder section of thick bamboo inside with connect circular plate (7) and pass through bearing (10) and be connected, the circumference of connection circular plate on threaded connection have a set of screw rod (11). The utility model is used for gas turbine bearing oil blanket bush's quick assembly disassembly.
Description
The technical field is as follows:
the utility model relates to a gas turbine bearing frame oil blanket bush quick assembly disassembly device.
Background art:
the oil seal bushing used for sealing oil is installed on a turbine bearing seat of the gas turbine, the oil seal bushing needs to be replaced after the long-term operation of the unit, a screw hole used for dismounting is formed in the end face of the oil seal bushing, a screw rod can be screwed up at the screw hole and directly pulled out, and the oil seal bushing is not prone to being dismounted due to the fact that a sealing ring is arranged on the outer circle of the oil seal bushing and is likely to deform after the long-term operation.
The utility model has the following contents:
the utility model aims at solving the influence of the upper seal ring of present oil blanket bush excircle to and probably produce the deformation after the long-term operation, the problem under the oil blanket bush is not easy to be dismantled provides one kind and can make the gas turbine bearing frame oil blanket bush quick assembly disassembly device that the oil blanket bush was dismantled fast.
The above purpose is realized by the following technical scheme:
the utility model provides a gas turbine bearing frame oil blanket bush quick assembly disassembly device which constitutes and includes: the supporting ring plate comprises a fixed ring plate, a group of stand columns are arranged on the circumference of the fixed ring plate, a supporting cylindrical barrel is arranged in the fixed ring plate, the stand columns penetrate through a round hole in the side face of the supporting cylindrical barrel, hydraulic jacks are fixed on support plates on two sides of the fixed ring plate through bolts, the upper portions of the hydraulic jacks are fixedly connected with rib plates on the side face of the supporting cylindrical barrel, the inside of the supporting cylindrical barrel is connected with a connecting ring plate through bearings, and a group of screw rods are connected to the circumference of the connecting ring plate in a threaded mode.
The quick dismounting device for the oil seal bushing of the gas turbine bearing seat is characterized in that compression rings of hydraulic jacks on the left side and the right side of the supporting cylindrical barrel are connected through compression rods.
The quick dismounting device for the oil seal bushing of the gas turbine bearing seat is characterized in that the number of the screws is 4.
Has the advantages that:
1. the utility model discloses pass through the bolt fastening with fixed ring board on the bearing frame, then will connect the screw rod on the ring board and twist on the oil blanket bush, move the depression bar through the pressure like this for hydraulic jack is with the quick dismantlement of oil blanket bush.
2. The utility model discloses need not pull the outside pulling of screw rod with the hand, can keep the oil blanket bush not squinting pulling the in-process simultaneously when the pulling, prevent to lead to wearing and tearing to the axle journal bump of rotor.
3. The utility model discloses connect between ring board and the support cylinder section of thick bamboo and be connected through the bearing, can rotate before oil blanket bush and the connection ring board is connected like this and connect the ring board for it is just right to connect the screw position on the double-screw bolt on the ring board and the oil blanket bush, convenient connection like this.
Description of the drawings:
FIG. 1 is a schematic structural diagram of the present invention;
FIG. 2 is a schematic structural view of an oil seal bushing on a bearing block;
in the figure: 1. a rib plate; 2. supporting the cylindrical drum; 3. a column; 4. fixing the circular plate; 5. a support plate; 6. a hydraulic jack; 7. connecting the circular ring plates; 8. a pressure lever; 9. a rubber sleeve; 10. a bearing; 11. a screw; 12. a bearing seat; 13. an oil seal bushing; 14. a rotor journal; 15. a screw hole; 16. and (5) pressing a ring.
The specific implementation mode is as follows:
example 1:
the utility model provides a gas turbine bearing frame oil blanket bush quick assembly disassembly device which constitutes and includes: the supporting plate and the fixed circular plate are integrated, the supporting cylinder barrel and the ribbed plate are also integrated, the inside of the supporting cylinder barrel is connected with the connecting circular plate 7 through a bearing 10, and the circumference of the connecting circular plate is in threaded connection with a group of screws 11.
Example 2:
according to embodiment 1 the quick assembly disassembly device of gas turbine bearing frame oil blanket bush, the clamping ring 16 that supports the hydraulic jack of cylinder left and right sides pass through the depression bar 8 and connect, the cover has gum cover 9 on the depression bar, can protect the hand of pressing the dynamic depression bar.
Example 3:
according to the gas turbine bearing seat oil seal bushing quick assembly disassembly device of embodiment 1 or 2, the quantity of screw rod be 4.
When the oil seal bushing is disassembled, the fixed circular ring plate and the bearing seat are fixed through the bolt, then the circular ring plate is connected in a rotating mode to enable the stud on the circular ring plate to correspond to the screw hole in the oil seal bushing, then the screw rod is screwed to enable the screw rod to be screwed into the screw hole in the oil seal bushing, then the pressing rod is pressed, the supporting cylindrical barrel slides under the action of the hydraulic jack, and the oil seal bushing is pulled out.
Claims (3)
