To the outside of packing ring.
Described guiding collar centre is provided with a centre bore, and is distributed some to leading with guiding collar centrosymmetry
Xiang Kong.
Described axle passes centre bore, and the centre bore concentric gap of described guiding collar coordinates.
Described threaded rod passes pilot hole, and several described pilot holes are suitable with the threaded rod of different size.
This attaching/detaching apparatus also comprises a pair hanger, and it is fixed in support ring.
This utility model compared with prior art, has the advantage that
(1) provide parts on shaft attaching/detaching apparatus in a kind of sealing chamber, be used for solving parts on shaft dismounting space in sealing chamber
Less, dismounting difficulty, it is easy to damage axle and the problem of part；
(2) the protection guiding collar of this attaching/detaching apparatus can be avoided in sealing chamber in parts on shaft disassembly process because of shaft vibration
Colliding with other parts of surrounding, countershaft and part plays a protective role；
(3), in sealing chamber during parts on shaft assembling, this attaching/detaching apparatus plays guiding by protection guiding collar and makees
With, it is ensured that assembly precision, improve assembling quality；
(4) a series of pilot holes of this attaching/detaching apparatus design can be used for the dismounting of multiple parts on shaft, in disassembly process,
Without changing dismantling device, save man-hour；
(5) for heavier part, this attaching/detaching apparatus is provided with hanger, uses the most dismantled and assembled parts on shaft of boom hoisting, knot
Structure is simple, it is easy to use；
(6) new thinking and breach are provided for the dismounting of part in other similar sealing chambers.
