DETAILED DESCRIPTION

[0014] In order to make the structure and function of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0015] See attached Figure 1-3 , a tool for installing and disassembling a half-moon retaining ring of a shaft system, comprising a first main body 1, a second main body 2, and a guide shaft 3; a first main body installation positioning groove and a first main body disassembly positioning groove are provided on a side of the first main body 1 close to the second main body 2, and a second main body installation positioning groove and a second main body disassembly positioning groove are provided on a side of the second main body 2 close to the first main body 1, the first main body installation positioning groove cooperates with the second main body installation positioning groove, the first main body disassembly positioning groove cooperates with the second main body disassembly positioning groove, the first main body installation positioning groove, the first main body disassembly positioning groove, the second main body installation positioning groove, and the second main body disassembly positioning groove are semicircular; there are two guide shafts 3, the two guide shafts 3 vertically penetrate the first main body 1 and the second main body 2, and the two guide shafts 3 are located at both ends of the first main body 1 and the second main body 2.

[0016] Furthermore, a half-moon snap ring mounting positioning groove plate 5 is arranged on the first main body mounting positioning groove, both ends of the groove of the half-moon snap ring mounting positioning groove plate 5 are recessed in the first main body 1, and the curvature of the groove of the half-moon snap ring mounting positioning groove plate 5 is equal to the curvature of the mounting positioning groove; a half-moon snap ring positioning mounting groove 7 is provided on the second main body mounting positioning groove, and the half-moon snap ring positioning mounting groove 7 matches the half-moon snap ring 10.

[0017] Furthermore, a half-moon clasp disassembly groove plate 6 is arranged on the disassembly positioning groove of the first main body, and both ends of the groove of the half-moon clasp disassembly groove plate 6 protrude from the first main body 1, and the curvature of the groove of the half-moon clasp disassembly groove plate 6 is equal to the curvature of the disassembly positioning groove; a half-moon clasp positioning escape groove 8 which can accommodate a half-moon clasp is provided on the disassembly positioning groove of the second main body, and the half-moon clasp positioning escape groove 8 matches the half-moon clasp disassembly groove plate 6.

[0018] Furthermore, two compression springs 4 are included. The compression springs 4 are sleeved on the circumference of the guide shaft 3 , and the compression springs 4 are located between the first body 1 and the second body 2 .

[0019] Furthermore, the installation steps of a shaft system half-moon retaining ring installation and removal tool are as follows: under the action of two compression springs 4, the original state of the first body 1 and the second body 2 is an open state; when the half-moon retaining ring needs to be installed in the retaining ring groove 9 of the shaft, the shaft is placed in the first body installation positioning groove, and the groove of the half-moon retaining ring installation positioning groove plate 5 is clamped in the retaining ring groove 9 of the shaft; the half-moon retaining ring 10 is placed in the half-moon retaining ring positioning installation groove 7, and the opening of the half-moon retaining ring 10 faces the first body 1; both hands simultaneously hold the handles on both sides of the first body 1 and the second body 2 and move them towards each other, so that the first body 1 and the second body 2 are completely fitted, and the half-moon retaining ring can be pressed into the retaining ring groove 9 of the shaft.

[0020] Furthermore, the disassembly steps of a half-moon snap ring installation and disassembly tool for a shaft system are as follows: under the action of two compression springs 4, the original states of the first body 1 and the second body 2 are in an open state; when the half-moon snap ring 10 installed in the snap ring groove 9 of the shaft needs to be disassembled, the shaft with the half-moon snap ring 10 is placed in the disassembly positioning groove of the second body, and the half-moon snap ring 10 is positioned in the half-moon snap ring positioning escape groove 8, with the opening of the half-moon snap ring facing the first body 1; both hands simultaneously hold the handles on both sides of the first body 1 and the second body 2 Use your hands to make the first body 1 and the second body 2 move towards each other so that the half-moon snap ring removal groove plate 6 contacts the half-moon snap ring 10; continue to apply force with both hands until the first body 1 and the second body 2 are in contact.
