The end face that mouth 2 is connected with no mouthpiece tube road 17 is equipped with gasket 1.
The oil nozzle 2 that connects is inserted into the mounting disc 3, specifically inserts mode are as follows: the oil nozzle 2 that connects is across the installation
Oil nozzle mounting hole is connect on disk 3, and is connect by the screw thread on its side wall with adjusting nut 7, the adjusting nut 7 passes through limit
Disk 5 and screw 8 are fixed on 3 lower section of mounting disc, and the position-arresting disk 5 is stuck between the adjusting nut 7 and the screw 8,
It is that the limitation adjusting nut 7 moves up and down that it, which is acted on,；3 side of mounting disc is additionally provided with spacer pin 4, and the spacer pin 4 blocks
It connects and is connect in oil nozzle lateral grooves 14 described, the effect of the spacer pin 4 is to further prevent described connecing oil nozzle 2 and rotating；
By rotating the adjusting nut 7, the oil nozzle 2 that connects only is subjected to displacement in vertical direction；The bottom for connecing oil nozzle 2 is also set
There is the connector 10 for installing flushing device, the installation place for connecing 2 bottom port of oil nozzle and the connector 10 is equipped with sealing ring
9。
In addition, described connect is additionally provided with positioning convex platform 12 on oil nozzle 2, for measure connect oil nozzle and without between mouthpiece tube road away from
From.
The attachment device is additionally provided with aligning bar 15, and structure is as shown in figure 5, one end of the aligning bar 15 is circular cone
Shape, the other end are equipped with handle 16, and the aligning bar 15, which is inserted into, described connects oil nozzle and without the connection in mouthpiece tube road for both making
Place's alignment, prevents the two from channeling bit when compressing.
The present embodiment without mouthpiece tube road attachment device when in use, will first connect oil nozzle 2 across mounting disc 3, by connecing oil
2 tailing screw flight of mouth is connect with adjusting nut 7, then is blocked adjusting nut 7 with position-arresting disk 5 and installed side, and position-arresting disk 5 is passed through screw
8 are fixed in mounting disc 3, and adjustment connects 2 position of oil nozzle, make its lateral grooves 14 alignment 3 side spacer pin of mounting disc, 4 mounting hole simultaneously
Spacer pin 4 is installed.Rotating adjusting nut 7, connecing oil nozzle 2 can freely move linearly above and below.Adjusting connects 12 lower end of oil nozzle positioning convex platform
To the distance L of 3 upper surface of mounting disc, when connecing oil nozzle 2 and combustion engine without meeting L=18 when mouth oil fuel tube 17 contacts, therefore with combustion engine
Without rotating adjusting nut 7 before mouth oil pipe is installed is connect, make to connect the distance L control of 12 lower end of oil nozzle positioning convex platform to 3 upper surface of mounting disc
System is 15 or so.4 are successively installed by above step and connects oil nozzle, and adjust L value.Gasket 1 is bonded in glue connect oil nozzle 2 with
On the end face that no mouthpiece tube road 17 is connected, it is sequentially completed 4 gasket bondings.
Then it will be placed into combustion engine High Pressure Turbine Rotor 19 without mouthpiece tube road attachment device, and oil nozzle 2 will be connect and connect with nothing
Mouth oil fuel tube 17 is aligned, and is secured the device on High Pressure Turbine Rotor 19 with clamp nut 6.Rotating adjusting nut 7 makes to connect oil nozzle
2 are slowly linearly close to and are pressed on by gasket 1 without connecing on mouth oil fuel tube 17.Connect oil nozzle 2 linearly to
Without connect mouth oil fuel tube 17 close to when, should be adjusted by 3 inner hole of mounting disc and connect 2 inclined-plane of oil nozzle, make its with it is oblique without mouth oil fuel tube 17 is connect
Face unanimously compresses afterwards.2 lower part of oil nozzle installation sealing ring 9 and erection joint 10 are being connect, finishing device and nothing meet the company of mouth oil fuel tube 17
It connects.Flushing device can lead to cleaning solution to bearing bore 18 by connector 10 and realize cleaning with pressure.No mouthpiece tube road attachment device and combustion
The scheme of installation of machine connection is as shown in Figure 3.
When being aligned during the installation process with combustion engine without mouth oil fuel tube 17 is connect to connect oil nozzle 2 in guarantee device, and preventing from compressing
Gasket 1 channels bit, and blocks latus rectum, aligning bar can be used (see Fig. 5).Combustion engine turbine will be placed into without mouthpiece tube road attachment device to turn
In son 19, combustion engine is inserted into without connecing in mouth oil fuel tube 17 by connecing 2 inner hole of oil nozzle with aligning bar 15, then secures the device to combustion again
On machine turbine rotor 19, at this moment rotating adjusting nut 7 again are not only protected to combustion engine without connecing when mouth oil fuel tube 17 compresses connecing oil nozzle 2
Two pieces concentricity is demonstrate,proved, 1 play of gasket is also prevented, blocks oiling channel.
The present embodiment efficiently solves no mouthpiece tube road and can not connect, and combustion engine bearing bore cannot achieve flushing problem with pressure,
It thoroughly solves bearing bore to rinse without pressure, greasy filth in bearing bore, fouling problem can not be thoroughly removed, so that it is sliding to solve bearing bore
Oil pipe line blocking, failure that sliding deficient oil supply causes that bearing oil returning-oil temperature is higher, combustion engine vibration is transfinited.
Although the embodiments of the present invention has been shown and described above, it is to be understood that above-described embodiment is example
Property, it is not considered as limiting the invention, those skilled in the art within the scope of the invention can be to above-mentioned
Embodiment is changed, modifies, replacement and variant.
