Background technology
In the prior art, steam turbine is connected by a secondary positive coupling with generator, rotor turning installation is put be loaded on after
On bearing cap, driven by motor, required barring speed, Turbine Barring Gears are reached by worm and gear and The gear deceleration
Rotating speed is 4.8 revs/min, and when the rotating speed of rotor is higher than barring speed, barring gear can automatically exit from operating position.
When turbine rotor needs input jiggering, artificial disc moves motor rotation dish, and hand push cranking lever axle rotates 45 degree
Binded to worm gear and gear, then start motor and carry out electric barring.When steam turbine red switch, rotary speed of rotator exceedes disk
During vehicle speed, rocker shaft drives worm gear to depart from gear, rotates 45 degree to completely disengaged position.Jiggering puts into and exited process rocking bar
Axle is required for 45 degree of rotation.Rocker shaft is fixed in two, the two ends axis hole of jiggering support, wherein a side joint operation handle, in addition
One side joint journey controller.
In the prior art, because rocker shaft and jiggering support axis hole are that gap coordinates, wherein without any sealing device, in rotor
Lubricating oil oozes out into two ends by the gap between rocker shaft and axis hole in operation process, flows on bearing housing, it is impossible to eliminate, and needs
Periodically to remove.
Problem is, on outflow of lubrication oil to jiggering support, bearing housing, not only wasted lubricating oil, influence environmental sanitation while but also
Cause potential safety hazard.
The content of the invention
In order to solve problem above, the present invention proposes a kind of Turbine Barring Gears rocking bar shaft sealer, including rocker shaft, machine
Seat, support both sides axis hole, joystick mounting seat, journey controller mounting seat, the rocker shaft are arranged in the support axis hole,
The joystick mounting seat and journey controller mounting seat are separately positioned on the two ends of the rocker shaft, are installed in the joystick
Joystick is set on seat, the rocker shaft is rotated progress electric barring by rotating joystick, is characterized in, in the correspondence machine
Seal is additionally provided with the position of seat axis hole, the seal seals, and prevents lubricating oil seepage from axle bed gap
Out.
The technical scheme that present invention solution technical problem is proposed is that the present invention proposes that a kind of Turbine Barring Gears rocker shaft is close
Seal apparatus, including rocker shaft, support, support both sides axis hole, joystick mounting seat, journey controller mounting seat, the rocker shaft
In the support axis hole, the joystick mounting seat and journey controller mounting seat are separately positioned on the rocker shaft
Two ends, joystick is set in the joystick mounting seat, the rocker shaft is rotated the electronic disk of progress by rotating joystick
Car, it is characterized in that, seal is additionally provided with the position of the correspondence support axis hole, the seal seals, prevented
Only lubricating oil is leaked out from axle bed gap.
Preferred scheme of the present invention is that sealing groove is set on the rocker shaft, and the seal is arranged on the axle
On sealed groove.
Preferred scheme of the present invention is that the providing holes sealed groove on the axis hole, the seal is arranged on the Kong Mi
Seal on groove.
Preferred scheme of the present invention is that the seal uses O-ring seals.
Beneficial effects of the present invention：Invention proposes a kind of Turbine Barring Gears rocking bar shaft sealer, in rocker shaft correspondence machine
Seal is additionally provided with the position of seat axis hole, seal seals, and can effectively prevent lubricating oil from axle bed gap
Leak out, it is to avoid lubricating oil is wasted, it is ensured that environmental sanitation avoids the occurrence of safety and fallen into simultaneously to be suffered from.
