For limiting and rotating disc skiving wheel.
Particularly, the transmission shaft top is equipped with the transmission axle handle for connecting reinforcing casing.
Particularly, the pin shaft one and pin shaft two are respectively positioned on transmission shaft, and pin shaft two is located at the top of pin shaft one.
Particularly, the flange is bolted on the casing flange above jiggering gear, flange and casing method
Orchid is adapted.
Particularly, the transmission shaft limiting slot is the rectangular channel for being adapted to transmission shaft size, and transmission shaft is limited in transmission shaft
It rotates a certain angle in the slot of position around pin shaft one.
A kind of working method of removable hand-barring, comprising the following steps:
1) barring gear is installed first, hydraulic impact type barring mechanism is removed, by the flange of barring gear and casing method
Orchid is connected with fastening, at this time transmission shaft vertical direction to good, and close to one end of transmission shaft limiting slot, hook is fallen naturally
On jiggering gear；
2) it followed by puts into gear, that is, holds and pull transmission axle handle, make transmission shaft is mobile in transmission shaft limiting slot to find
It puts into gear position, until transmission axle handle can not move painstakingly, the between cog of the jiggering gear of hook insertion at this time；
3) then make jiggering, be that reinforcing casing is mounted on transmission axle handle after hook is embedded between jiggering gear after extension shelves
On, reinforcing casing is pushed, until another end in contact of transmission shaft and transmission shaft limiting slot, hook is just with barring gear at this time
The distance of a tooth is rotated, that is, completes a jiggering；
4) finally pull transmission axle handle that transmission shaft is retracted vertical position, hook is embedded in the next of jiggering gear at this time
Between cog；
5) angle needed according to jiggering repeats step 2-4, i.e., pulls transmission shaft handle repeatedly in transmission shaft limiting slot
Hand realizes accurate jiggering.
The invention has the following advantages:
The transmission shaft and hook that the present invention designs form lever construction under the rotation of pin shaft one and pin shaft two, both safe,
Stablize labour-saving again to realize to stem-driven turboblower rotor progress jiggering, greatly reduces the labor intensity of operator, improve disk
Vehicle efficiency；The rotation jiggering of one tooth of a tooth between the hook and jiggering gear of design, make barring gear region power failure oil pump without
Method is more accurate when working；The flange of design is adapted with casing flange and connect, easy for removal and installation；It avoids simultaneously and utilizes sled
The problem of rod agitates main shaft or damaged with the methods of driving wiring jiggering to people or equipment, barring gear is highly-safe, real
It is strong with property.
