[0020] Hereinafter, exemplary embodiments of the present invention will be described in more detail with reference to the drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and is not limited by the embodiments described herein. Rather, these embodiments are provided so that the present invention can be better understood and the scope of the present invention can be fully conveyed to those skilled in the art.

[0021] In an embodiment of the present invention, a speed reducer box structure is provided. The speed reducer box structure includes a front box 2, a rear box 1, and a connection column 3. The front box 2 and the rear box 1 are hermetically connected, and a cavity structure for accommodating a speed reducer is formed inside. The connection between the front box 2 and the rear box 1 is realized through screw holes on the outer sides of the front box 2 and the rear box 1.

[0022] As shown in FIGS. 1 to 5, the connection column 3 is provided inside the cavity structure and is removably or partially removably connected between the front box 2 and the rear box 1. The connection method between the connection column 3 and the front box 2 and the rear box 1 is connection by bolts 4 or integral casting. The connection column 3 is used to improve the connection strength of the speed reducer box structure, reduce the vibration of the box, and improve the NVH (Noise, Vibration, Harshness) performance of the speed reducer.

[0023] The shape of the connecting column 3 may be a cylinder, a cuboid, or other cube shapes, and the installation position of the connecting column 3 within the cavity structure can be set according to the structure of the speed reducer. The connecting column 3 can enhance the connection strength between the front box 2 and the rear box 1 of the speed reducer, reduce the deformation of the front box 2 and the rear box 1 of the speed reducer to a certain extent during the operation process, and improve the NVH performance of the speed reducer. Moreover, the speed reducer box structure is easy to install and occupies a small space.

[0024] In one embodiment, as shown in FIGS. 1 and 2, both ends of the connecting column 3 are respectively connected and fixed to the front box 2 and the rear box 1 via one or more bolts 4. By connecting and fixing the connecting column 3 and the front box 2 or the rear box 1 via a plurality of bolts 4, the contact area between the connecting column 3 and the front box 2 or the rear box 1 is large, and it is easy to fix with a plurality of bolts 4.

[0025] In one embodiment, as shown in FIGS. 3 and 4, the connecting column 3 is integrally cast and formed with either the front box 2 or the rear box 1, and is connected and fixed to the other via one or more bolts 4.

[0026] In one embodiment, as shown in FIG. 5, the connecting column 3 has at least two sections integrally cast and formed with the front box 2 and the rear box 1 respectively, and the connecting column 3 of each section is connected and fixed via one or more bolts 4. When the connecting column 3 has two sections, the two sections are integrally cast and formed with the front box 2 and the rear box 1 respectively, and then are connected and fixed to the connecting column 3 of the two sections via bolts 4.

[0027] In one embodiment, the material of the connecting column 3 is an alloy material. When the connecting column 3 and the transmission box are integrally cast, the material of the connecting column 3 is the same as that of the transmission box. When the connecting column 3 and the transmission box are connected via bolts 4, the material of the connecting column 3 may be the same as that of the transmission box or an alloy of other materials.

[0028] In one embodiment, the alloy material is any one of alloy steel, alloy aluminum, and alloy copper. Of course, considering factors such as economy, connection strength, and vibration reduction, it is preferable to use alloy steel material.

[0029] In one embodiment, several connecting columns 3 may be provided. By providing a plurality of connecting columns 3 at appropriate positions within the cavity structure, the strength and vibration damping performance of the box structure are further enhanced.

[0030] In one embodiment, the connecting column 3 is stepped. This makes it easier to connect a plurality of bolts and increases the contact area with the front box and the rear box.

[0031] In one embodiment, referring to FIGS. 1 to 4, the bolt 4 is inserted into the front box or the rear box and the connecting column 3 from the outside of the front box 2 or the rear box 1. Preferably, the bolt 4 is further provided with an anti-drop structure to prevent the bolt from dropping during the operation of the reducer.

[0032] In one embodiment, the front box 2 and the rear box 1 are provided with flanges perpendicular to the front box or the rear box at the sealed connection locations. The flanges are connected and fixed by bolts and nuts, and the flanges can be installed at any length position of the box structure over the entire circumference of the box structure. This makes it easy to achieve sealing and fixed connection.

[0033] Briefly, in the present invention, a speed reducer box structure is proposed. The speed reducer box structure includes a front box, a rear box, and a connection column. The front box and the rear box are hermetically connected, and a cavity structure for accommodating the speed reducer is formed inside. The connection column is provided in the cavity structure and is removably or partially removably connected between the front box and the rear box. The connection method between the connection column and the front box and the rear box is connection by bolts or integral casting. The connection column is used to improve the connection strength of the speed reducer box structure, reduce the vibration of the box, and improve the NVH performance of the speed reducer. The speed reducer box structure according to the present invention strengthens the connection strength of the speed reducer box by providing a connection column between the front box and the rear box, effectively reduces the vibration of the speed reducer box, reduces the deformation of the front box and the rear box of the speed reducer to a certain extent during the operation process, improves the NVH of the speed reducer alone or the power assembly. In addition, the speed reducer box structure has a simple installation operation and a small occupied space.
