[0025] Please refer to Figure 1 and Figure 3 , this embodiment provides a bearing support device for a large-load planetary gear, including a limiting circular tube 6. One end of the limiting circular tube 6 is rotatably connected to a limiting disc 2. A plurality of supporting mechanisms 3 for supporting the bearing are arranged on the side surface of the limiting disc 2. During use, the supporting mechanism 3 provides a supporting effect for the bearing of the planetary gear. The supporting mechanism 3 includes a supporting base 34. One end of the supporting base 34 close to the limiting disc 2 is rotatably connected to a limiting bearing 31 corresponding to the limiting disc 2. The other end of the supporting base 34 is provided with a supporting component 35 for supporting the bearing. During use, the supporting component 35 provides a limiting and supporting effect for the bearing of the planetary gear. One end of the supporting base 34 close to the limiting bearing 31 is provided with a fixing component 39 for fixing the supporting component 35;

[0026] Please refer to Figure 3 and Figure 4, in one embodiment, to make the use of the support component 35 more reliable, in this embodiment, preferably, the support component 35 includes a limit support disk 353. On one side of the limit support disk 353, there is a limit square rod 352 corresponding to the support base 34. On the other side of the limit support disk 353, there is a limit protrusion 354 for cooperating with the limit support disk 353 to support the bearing. At the end of the limit square rod 352 away from the limit support disk 353, there is a limit chute 351;

[0027] During use, the limit support disk 353 cooperates with the limit protrusion 354 to support the bearing of the planetary gear. The combined setting of the limit support disk 353 and the limit square rod 352 facilitates the user to quickly replace the support component 35 of different models;

[0028] In another embodiment, the support component 35 includes a limit support disk 353. On one side of the limit support disk 353, there is a limit square rod 352 corresponding to the support base 34. On the other side of the limit support disk 353, there is a limit protrusion 354 for cooperating with the limit support disk 353 to support the bearing. At the end of the limit square rod 352 away from the limit support disk 353, there is an anti-slip protrusion;

[0029] Please refer to Figure 3 , in one embodiment, to make the use of the fixing component 39 more reliable, in this embodiment, preferably, the fixing component 39 includes an adjusting screw rod 32 rotatably connected to the support base 34. On one side of the adjusting screw rod 32, there is a limit clamping plate 36 corresponding to the limit chute 351. At both ends of the adjusting screw rod 32, there are limit sliders 38 threadedly connected for cooperating with the limit clamping plate 36 to fix the limit square rod 352;

[0030] Please refer to Figure 3 , in one embodiment, to further improve the fixing effect of the fixing component 39, in this embodiment, preferably, on one side of the adjusting screw rod 32, there is a limit sliding plate 33 slidably connected to the limit clamping plate 36. The setting of the limit sliding plate 33 prevents the limit clamping plate 36 from tilting during the adjustment process. At the end of the limit clamping plate 36 away from the limit slider 38, there is an elastic buffer plate 37 for fixing the limit square rod 352. In this embodiment, preferably, the material of the elastic buffer plate 37 is rubber or silica gel;

[0031] When it is necessary to fix the limit square rod 352, the user rotates the adjusting screw rod 32 by using a screwdriver or a wrench, so that the limit sliders 38 at both ends of the adjusting screw rod 32 approach each other along the adjusting screw rod 32. At this time, the limit square rod 352 is fixed by the approaching of the limit clamping plates 36. The elastic buffer plate 37 plays an anti-slip and buffering role, improving the fixing effect of the limit clamping plate 36 on the limit square rod 352 and making the use of the device more reliable;

[0032] In another embodiment, the fixing component 39 includes a mounting substrate fixedly arranged at the bottom of the support base 34. Hydraulic cylinders for fixing the limiting square rod 352 are arranged at both ends of the mounting substrate. When in use, the limiting square rod 352 is fixed by the extension of the hydraulic cylinders.

[0033] Please refer to Figure 1 and Figure 2 In one embodiment, in order to further improve the reliability of the bearing support device, preferably, a limiting support member 5 is arranged at one end of the limiting circular tube 6 far from the limiting disc 2, and a connecting base 1 slidably connected to the limiting support member 5 is arranged on the other side of the limiting disc 2. A plurality of limiting balls 4 corresponding to the limiting support member 5 are arranged at one end of the connecting base 1 close to the limiting disc 2. The arrangement of the limiting balls 4 makes the frictional resistance smaller when the limiting support member 5 slides inside the connecting base 1.

[0034] When in use, through the mutual cooperation of the limiting support member 5, the connecting base 1 and the limiting balls 4, and in cooperation with the limiting circular tube 6, the limiting support is provided for the limiting disc 2, avoiding the inclination of the limiting disc 2 during use and improving the reliability of the support device.

[0035] The working principle and usage process of the present invention: Before use, the user fixedly supports the limiting support member 5 and the limiting circular tube 6 in a conventional manner, penetrates the transmission shaft for driving the sun gear to rotate through the limiting circular tube 6 and rotatably connects it with the limiting circular tube 6 through a bearing. Then, the limiting support disc 353 is located below the bearing of the planetary pinion of the planetary gear, and the limiting protrusion 354 is inserted into the bearing of the planetary pinion. The limiting support for the bearing of the planetary pinion is achieved through the mutual cooperation of the limiting support disc 353 and the limiting protrusion 354.

[0036] Secondly, the user can make the support device meet the support requirements in different scenarios by replacing different models of the support component 35 and adjusting the distance between the limiting support disc 353 and the support base 34. Thus, the support device can provide limiting support for the bearing of the planetary gear through the linkage cooperation of multiple structures, and can meet diverse support requirements, making the applicable range of the bearing support device wider. In addition, the present invention has low cost and low failure rate, and is worthy of popularization and use.
