Background
Present industrial machinery equipment, a lot of all use gear drive, and the gear precision is high, so can not cause the damage to the gear at the in-process of installation and dismantlement, and most gear all is interference fit with the installation of axle, so mostly use hydraulic pressure when dismantling and draw the horse, but because organism structural design and the little reason of gear, draw when the gear is dismantled draw the horse draw the claw not enough space to stretch into behind the gear, so need cooperate dismounting device.
However, in the case that the space is sufficient in the generally applicable scenes of the existing disassembling tool, such as a patent gear disassembling tool (CN 212372100U), it discloses a tool for limiting and clamping a gear by controlling a telescopic frame, but the problem is that some using scenes do not have enough space to place the gear into the frame, and the gear can not be disassembled.
SUMMERY OF THE UTILITY MODEL
The invention aims to: the utility model aims to solve the problem that current gear extracting tool can't be applicable to and can't stretch into whole disassembly body and lead to carrying out the gear dismantlement.
In order to solve the problem, the utility model adopts the following technical scheme:
the utility model provides a frock is dismantled to gear for screw rod fan, be the equal same component of semicircle annular and inner ring diameter and outer loop diameter including two cross-sections, the semicircle tangent plane of two components constitutes radial plane, radial plane all coincides with the diameter of current component, the inner ring surface of two components is close to the annular extension face that any end position of component thickness direction formed along inner ring surface extension, all be equipped with on the radial plane of two components and be used for passing through bolted connection first screw together with two components, all have on the annular plane of two components along the second screw that current component thickness direction has run through whole component, the cooperation sets up the rings that have the bolt that can fix in the second screw.
During the use, stretch into the rear of the gear that needs dismantled with two semicircle annular components earlier, then make up two components, form the circular shape whole, rotatory whole for have enough space can accomplish holistic fixing through first screw cooperation bolt, then pack into rings in the second screw, cooperate the outside apparatus that can stimulate rings again and can dismantle the gear that is surrounded by two components at present.
Further, the two components are matched to form a complete annular tool with a circular extending surface positioned on the surface of the inner ring.
Furthermore, a first step surface for exposing the first screw hole is formed at the semicircular position of the first screw hole arranged on any component.
One is in order to practice thrift the space, simultaneously, is in order to reserve the space that can put into the bolt in the mounted position of first screw, prevents that the space of screw fan in-connection mounting bolt from not having all.
Further, the first screw holes are all parallel to a circle tangent of the current member.
Further, the first screw hole and the second screw hole are both provided with threads.
It is also necessary that the screw thread is a rotary connection, and the second screw hole is directly connected with the bolt in a stable manner.
Further, the second screw holes are all located in the middle of the current member.
Better pressure sharing.
Further, the inner diameter of the circular extending surface is smaller than the outer diameter of the gear of the screw fan to be disassembled.
The circular extending surface forms a limiting surface, the circular extending surface can be driven to drive the gear under the pulling of the component, and the gear is detached.
Furthermore, the screw hole structure further comprises a second step surface, the second step surface is perpendicular to the first step surface, and the length extension direction of the second step surface is the same as that of the first screw hole.
The first step surface is used for facilitating installation of the bolt, and the second step surface is used for further expanding the installation space of the bolt, so that the integral space is formed.
Has the advantages that: compared with the prior art, the utility model has the advantages of it is following:
adopt the utility model discloses a design, simple structure, but to can be applied to the nervous scene of less gear station in the screw rod fan, dismantle less gear, be rich in the practicality.

Detailed Description
The present invention will be further described with reference to the accompanying drawings and examples.
Examples
As shown in fig. 1 to 5, a gear disassembling tool for a screw fan comprises two members 1 with semicircular sections and the same inner ring diameter and outer ring diameter, wherein semicircular cutting surfaces of the two members 1 form a radial plane 2, the radial plane 2 coincides with the diameter of the current member 1, annular extension surfaces 3 extending along the inner ring surface are formed at any end positions of the inner ring surfaces of the two members 1 close to the thickness direction of the member, first screw holes 4 used for connecting the two members 1 together through bolts are formed in the radial plane 2 of the two members 1, second screw holes 5 penetrating through the whole member along the thickness direction of the current member 1 are formed in the annular planes of the two members 1, and lifting rings 6 with bolts capable of being fixed in the second screw holes are arranged in the second screw holes 5 in a matching manner.
During the use, stretch into the rear of the gear 7 of required dismantlement with two semicircle annular components 1 earlier, then make up two components, form the circular shape whole, rotatory whole for have enough space can accomplish holistic fixed through first screw 4 cooperation bolt, then pack into rings 6 in second screw 5, cooperate the outside apparatus that can stimulate rings 6 again and can dismantle the gear 7 that is currently surrounded by two components.
