Description
Technical field
The utility model relates to steam feed pump field more particularly to a kind of steam feed pump toothed coupling external tooth tooth hubs
Extracting tool.
Background technique
In steam feed pump use process, shaft coupling external tooth Chi Grains is often used interference fit with inner shaft and is attached,
It needs to dismantle it in maintenance process, traditional extracting tool be easy to cause uneven at Chi Grains stress, and structure is not enough closed
Reason.
Utility model content
The utility model In view of the above shortcomings of the prior art, provides a kind of structurally reasonable steam feed pump flute profile
Shaft coupling external tooth tooth hub extracting tool.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of steam feed pump toothed coupling external tooth tooth hub extracting tool, including external tooth Chi Grains, pressure dynamic plate, driving bottom
Plate, postive stop baffle, Rotational Cylindrical, drive pin, connection bolt, the middle part external tooth Chi Grains have inner shaft, have outside external tooth Chi Grains
It is uniformly distributed foreign exchange outside Chi Grains , Chi Grains, there is pressing top plate, pressing top plate Yu Chi Grains cooperation, pressure inside the pressure dynamic plate
There is outside movable plate column, there is external screw thread outside column, the driving base plate interior has an internal thread groove, internal thread groove with outside
For screw thread tightly, driving base plate interior has taper turn trough.
There is axis hole, axis hole internal symmetry is distributed fixed thread slot, and the postive stop baffle has inside the external tooth Chi Grains
Plate body, plate body internal symmetry are distributed connection screw thread hole, have driving threaded hole inside postive stop baffle, the Rotational Cylindrical top has
Threaded post, threaded post lower part have platen, and platen bottom has cone-shaped nib, and platen is placed in axis hole, cone-shaped nib and taper
Turn trough cooperation.
There is pin hole, driving threaded hole and threaded post cooperate, connection screw thread hole and fixed thread slot inside the Rotational Cylindrical
Cooperation, connection bolt are inserted into connection screw thread hole and fixed thread slot tight, pin joint in drive pin insertion pin hole.
The utility model has the advantages that
Rotate driving pin drives threaded post, and platen presses driving bottom plate and moves downward, and pressing top plate presses Chi Grains and transports downwards
Dynamic, the area of contact surface is larger, and the pressure that the steady , Chi Grains of drive force is subject to is uniform, structurally reasonable, pressure dynamic plate, driving
The common cooperation of bottom plate, postive stop baffle, Rotational Cylindrical, using being threadedly coupled, connection is relatively easy to, easy to disassemble to make for junction
With structurally reasonable.
