Abstract
The utility model discloses a pump shaft sleeve dismounting tool which comprises a sleeve and a lead screw, wherein the lead screw is detachably connected to the top end of the sleeve, the sleeve is composed of a force bearing end plate and a cylinder body, the force bearing end plate and the cylinder body are fixedly welded, an internal thread is arranged on the inner wall of the bottom of the cylinder body, and the outer wall of the lead screw is of a full-thread structure. The disassembling tool is simple in structure, safe, reliable, easy to operate and high in practicability.
Description
Technical Field
The utility model relates to a disassembling tool, in particular to a pump shaft sleeve disassembling tool which is suitable for disassembling a shaft sleeve with external threads and belongs to the field of mechanical tools.
Background
In actual production, the axle sleeve often can be installed to a lot of rotating equipment bearing seal departments and be used for preventing the main shaft damage, and equipment process long-term operation, the axle sleeve is because the corrosion is stuck, and is difficult for exerting external force, leads to it to be hardly dismantled, needs heat treatment usually, still needs the destructiveness to demolish under the special circumstances, causes physics and high temperature damage easily to the main shaft, brings the equipment potential safety hazard.
SUMMERY OF THE UTILITY MODEL
In view of the above problems, an object of the present invention is to provide a pump shaft sleeve dismounting tool, which solves the problems in the prior art that external force is not easily applied to dismounting a shaft sleeve and the shaft sleeve is easily damaged.
In order to realize the purpose of the utility model, the utility model is realized by the following technical scheme:
the utility model provides a pump shaft sleeve extracting tool, includes sleeve and lead screw, and the telescopic top is connected to the lead screw dismantlement formula, the sleeve comprises load end plate and stack shell, load end plate and stack shell welded fastening, and the inner wall of stack shell bottom is provided with the internal thread, the lead screw outer wall be full thread structure.
The further improvement lies in that: the cylinder body extends from the two sides of the bearing end plate to form a bearing boss, and the bearing end plate and the bearing boss are of an integrated structure.
The further improvement lies in that: the center of the bearing end plate is provided with a threaded hole, and the lead screw is detachably connected with the bearing end plate through the threaded hole.
The further improvement lies in that: the top of the screw rod is of a square structure.
The utility model has the beneficial effects that:
1. the lead screw is connected on the top of the sleeve in a detachable mode through a threaded structure, so that the lead screw is convenient to detach, install, maintain and carry, is convenient to replace and reduces cost.
2. The cylinder body extends from the two sides of the bearing end plate to form bearing bosses, and when the shaft sleeve is disassembled, the bearing bosses on the two sides can be knocked, so that the shaft sleeve is convenient to disassemble.
3. The lead screw is connected on the top of axle sleeve, and the lead screw outer wall is full thread structure, and when the axle sleeve cooperation tight power is great, the axle sleeve is demolishd to the rotatory lead screw increase dynamics of accessible.
4. Through the setting of stack shell, the axle sleeve is demolishd to the internal thread of accessible stack shell inner wall, when meetting the axle sleeve of demolising the difficulty, also can carry out surface heating to the stack shell to the interval heating axle sleeve both multiplicable axle sleeve fit clearance, the demolishment of the axle sleeve of being convenient for has also avoided the damage of direct heating axle sleeve to the axle sleeve.
In summary, the utility model can rapidly and safely remove the shaft sleeve with the external thread, and has the characteristics of wide application range, simple structure, safety, reliability, easy operation, high practicability and the like.

fig. 2 is a schematic top view of the present invention.
Wherein: 1. a sleeve; 2. a lead screw; 101. bearing end plate 102, cylinder body 103, bearing boss.
Detailed Description
In order to further understand the present invention, the following detailed description will be made with reference to the following examples, which are only used for explaining the present invention and are not to be construed as limiting the scope of the present invention.
According to fig. 1 and 2, the embodiment provides a pump shaft sleeve dismounting tool, which comprises a sleeve 1 and a lead screw 2, wherein the sleeve 1 is composed of a force bearing end plate 101 and a cylinder body 102, the force bearing end plate 101 and the cylinder body 102 are welded and fixed, inner threads are arranged on the inner wall of the bottom of the cylinder body 102, force bearing bosses 103 are formed by extending out of the cylinder body from two sides of the force bearing end plate 101, and the force bearing end plate 101 and the force bearing bosses 103 are of an integrated structure; the center of the bearing end plate 101 is provided with a threaded hole, the screw rod 2 is detachably connected with the bearing end plate through the threaded hole, the outer wall of the screw rod is of a full-thread structure, and the top of the screw rod is of a square structure, so that the spanner operation is convenient to use.
When dismantling the during operation, with the muffjoint at the axle head, make telescopic internal thread and axle sleeve thread fit through the rotation, after the installation, strike both sides load boss simultaneously, demolish the axle sleeve, it is great like axle sleeve cooperation tight power, the rotatory lead screw of accessible increases the dynamics and demolishs the axle sleeve, can carry out surface heating to the stack shell when necessary to increase the fit clearance, the demolishment of the axle sleeve of being convenient for.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the utility model as claimed. The scope of the utility model is defined by the appended claims and equivalents thereof.
