a plurality of threaded holes are uniformly formed in the circumferential direction of the fixing ring, a plurality of wrench holes are uniformly formed in the circumferential direction of the movable toothed ring, and a plurality of threaded holes and wrench holes are uniformly formed in the circumferential direction of the fixing toothed ring;

when the axial shrink fit device is used, the fixing ring, the movable gear ring and the fixed gear ring are sequentially sleeved on the axial shrink fit part, the axial shrink fit part is composed of a part A and a part B which are sleeved together, the fixing ring and the fixed gear ring are respectively sleeved on one part of the axial shrink fit part and are fastened through a fastener, the movable gear ring and the fixed gear ring are meshed together, the movable gear ring is screwed, so that the tooth tips of the movable gear ring and the fixed gear ring are separated, and meanwhile, the axial shrink fit part is driven to be separated.

The invention has the further improvement that the end surfaces of the movable gear ring and the fixed gear ring are respectively provided with one or more teeth which can be meshed with each other.

A further improvement of the invention is that the fasteners are screws or pins.

The invention is further improved in that a shaft shoulder is arranged on the part A or the part B of the axial sleeve part and used for replacing a fixing ring.

The invention is further improved in that the invention also comprises two hook head wrenches which are used for respectively hooking the movable gear ring and the fixed gear ring and rotating in opposite directions to separate the engaged tooth tips of the movable gear ring and the fixed gear ring and drive the part A and the part B to be separated.

The invention has the following beneficial technical effects:

the invention provides a toothed ring type disassembling tool, which comprises a fixed ring, a movable toothed ring, a fixed screw and the like. In order to separate the part A and the part B which are sleeved together, the fixed ring, the movable toothed ring and the fixed toothed ring are sequentially sleeved into the part A and the part B. Wherein the movable toothed ring and the fixed toothed ring are engaged with each other. Fixing the fixed ring on the part A by using a fastener, fixing the fixed toothed ring on the part B by using the fastener, and twisting the movable toothed ring to separate the tooth tips of the movable toothed ring and the fixed toothed ring and drive the separated axial sleeve part at the same time.

Furthermore, the movable gear ring and the fixed gear ring are respectively hooked by the two hook head wrenches and rotate in opposite directions, so that the mutually meshed gear tips of the movable gear ring and the fixed gear ring are separated, and meanwhile, the part A and the part B are driven to be separated.

Therefore, the invention can rapidly and laborsavingly disassemble two axially sleeved parts, is simple to use, saves manpower and cannot damage the parts.

Detailed Description

The invention is further described below with reference to the accompanying drawings.

As shown in fig. 1 and 2, the present invention is composed of a fixed ring 1, a movable ring gear 2, a fixed ring gear 3, a fastener 4, and the like. The fixed ring 1 is a circular ring, and a plurality of threaded holes are distributed on the surface of the fixed ring. The movable gear ring 2 is a circular ring, a plurality of wrench holes are distributed on the surface of the circular ring, and n tooth tips n on one side of the circular ring are positive integers. The fixed gear ring 3 is a circular ring, a plurality of threaded holes and a plurality of wrench holes are distributed on the surface of the circular ring, n tooth tips are arranged on one side of the circular ring, and the shape of the tooth tips is consistent with that of the movable gear ring 2. The fixing screws can be mounted in threaded holes of the fixing ring 1 and the fixing ring gear 3.

As shown in FIG. 3, the axial sleeve parts to be disassembled are composed of a part A5, a part B6, a sealing ring 7 and the like. The axial nesting part to be disassembled cannot be directly pulled open by manpower due to the reasons of large size, heavy weight, sealing rings, smooth surface, tight fit and the like. A plurality of counter bores are distributed on the part A5 and the part B6, so that tools can be fixed conveniently.

As shown in fig. 1 to 4, the ring gear type removal tool 8 includes a fixed ring 1, a movable ring gear 2, a fixed ring gear 3, a fastener 4, and the like. The axial sleeve part 9 comprises a part A5, a part B6, a sealing ring 7 and the like. To remove the axial socket part 9, a ring gear removal tool 8 is inserted into the axial socket part 9. Wherein the movable toothed ring 2 is engaged with the fixed toothed ring 3. Tightening of the fastener 4 fixes the fixing ring 1 to the part a5 and the fixing ring 3 to the part B6. The two hook end wrenches 10 are respectively hooked on the wrench holes of the movable toothed ring 2 and the fixed toothed ring 3, and rotate along opposite directions, so that the tooth tips meshed with the movable toothed ring 2 and the fixed toothed ring 3 are separated, and meanwhile, a part A5 and a part B6 are driven to be separated.
