[0025] To make the objectives, advantages, and features of this utility model clearer, the following detailed description of an installation tool for a floating seal of a traveling speed reducer, in conjunction with the accompanying drawings and specific embodiments, will further clarify the advantages and features of this utility model. The advantages and features of this utility model will become clearer according to the following specific embodiments.

[0026] See Figure 2 and Figure 3 This embodiment of an installation tool for a floating seal of a traveling speed reducer mainly includes an installation tool body 1.

[0027] Specifically, the aforementioned installation tool body 1 is made of an elastic material, which facilitates the elastic opening and closing of the installation tool body 1 during installation / removal, making it easy to quickly attach to or remove from the floating sealing ring 01. Preferably, in this embodiment, it is made of polyester-methylene. Of course, in other embodiments of this utility model, those skilled in the art can also select other alternative materials with similar properties to polyester-methylene, such as POM engineering plastics, from existing materials.

[0028] The installation tool body 1 has a ring-shaped structure, and its radial dimension is adapted to the radial dimension of the floating seal ring 02 to be installed. This ensures sufficient radial stability when the installation tool body 1 is installed on the floating seal ring 01, preventing the floating seal ring 02 from not being installed properly due to radial runout, and ensuring uniform force transmission during the installation process.

[0029] The installation tool body 1 is provided with a cut-off port 2 that extends both axially and radially. The cut-off port 2 allows the installation tool body 1 to be opened when connecting to or removing from the floating sealing ring 01, thus enabling convenient installation and disassembly of the installation tool body 1. The structure is simple and easy to use.

[0030] Since the floating sealing ring 01 on the travel reducer has a protrusion on its circumference, in order to increase the contact area between the installation tool body 1 and the floating sealing ring 02, an annular groove 3 is provided on the inner side of the installation tool body 1 along the circumferential direction. The axial cross-sectional shape of the annular groove 3 is rectangular. The depth of the annular groove 3 is adapted to the radial dimension of the protrusion of the floating sealing ring 01, and the width is greater than the axial dimension of the protrusion. When the installation tool body 1 applies an axial compressive force to the floating sealing ring 02 to be installed, it causes axial displacement, thereby installing the floating sealing ring 02 into the sealing installation groove 03 of the travel reducer.

[0031] Preferably, in order to further increase the contact area and avoid deformation of the floating seal ring 02 due to local stress concentration, an inclined surface is provided at the inner edge of one end face of the installation tool body 1. The inclination angle of the inclined surface is 30° to 60°, which can be selected according to the shape and size of the floating seal ring 02 to be installed, with the maximum contact area as the selection criterion.

[0032] When using:

[0033] 1. First, open the installation tool body 1 along the cut-off point and put it on the floating sealing ring 01, so that the annular groove on the inner side of the installation tool body 1 is engaged with the annular protrusion of the floating sealing ring 01, thereby realizing the quick positioning and installation of the installation tool body 1.

[0034] 2. Next, place the floating seal ring 02 on the sealing mounting groove 03 of the travel reducer, and press the installation tool body 1 symmetrically in the circumferential direction to make the installation tool body 1 move axially, and finally install the floating seal ring 02 into the sealing mounting groove.

[0035] 3. Finally, open the installation tool body 1 along the cut-off point and remove the installation tool body 1 for subsequent use.
