[0031] In use, during the output transmission of the main transmission mechanism 2, one gear part 43 inside the transition gear box 4 can rotate synchronously with the corresponding transmission end inside the main transmission mechanism 2, and then the synchronous transmission output of the roller transmission mechanism 3 under the transmission of the corresponding gear part 43 is realized through the mutual meshing transmission among the four gear parts 43, so as to meet the operation requirement of the overall equipment, and the use of the transition gear box 4 can ensure the long-term stable transmission while ensuring the rigid transmission efficiency compared with the cross shaft transmission and the belt transmission in the prior art, and the overall result of the transition gear box 4 is solid and durable, and the noise is small.

[0032] Embodiment two

[0033] Please refer to Figure 4 The inner wall of the semi-open box body 41 is provided with a combination thread hole, the inside of the sealing box plate 42 is provided with a combination hole 5 aligned with the combination thread hole, and the combination hole 5 is sleeved with a positioning screw 6 capable of being screw-locked with the combination thread hole. The number of combination thread holes, the number of combination holes 5 and the number of positioning screws 6 are the same and are set one by one, so as to ensure the assembly strength of the semi-open box body 41 and the sealing box plate 42.

[0034] In use, for the convenience of maintenance of the four gear parts 43 inside the transition gear box 4, the semi-open box body 41 and the sealing box plate 42 are in a reciprocating detachable installation state, and then only the positioning screw 6 between the semi-open box body 41 and the sealing box plate 42 needs to be disassembled, and the sealing box plate 42 is taken out, so that the four gear parts 43 can be completely exposed, providing sufficient space for maintenance work, and then creating favorable conditions for improving the service life of the four gear parts 43.

[0038] Embodiment Four

[0039] Please refer to Figures 5-8 The middle of each reinforcing frame 7 is provided with mounting holes, and a buffer assembly 8 is arranged in each mounting hole. The buffer assembly 8 includes an arc-shaped ring plate 81 and a damping ball 82. The arc-shaped ring plate 81 is fixedly sleeved in the corresponding mounting hole, and the damping ball 82 is sleeved inside the arc-shaped ring plate 81. The damping ball 82 can reciprocally roll inside the arc-shaped ring plate 81 while being in contact with the corresponding gear body 432. The buffer assembly 8 can frictionally dissipate energy and buffer the corresponding gear part 43 under the support of the reinforcing frame 7, thereby ensuring the stable meshing transmission of the four gear parts 43 while also reducing the meshing friction noise of the four gear parts 43 to a certain extent.

[0040] A damping sheet 83, a buffer spring 84, and a support frame plate 85 are sleeved in the mounting hole. The damping sheet 83 is clamped in the corresponding mounting hole, and the support frame plate 85 is fixedly sleeved inside the mounting hole. The two ends of the buffer spring 84 are fixed to the surfaces of the damping sheet 83 and the support frame plate 85, respectively. Thus, the damping structure composed of the buffer spring 84, the damping sheet 83, and the support frame plate 85 is used synchronously with the damping ball 82, thereby performing multiple damping and buffering on the corresponding gear body 432. The inside of the support frame plate 85 is provided with a plurality of ventilation grooves in communication with the space of the corresponding mounting hole. Thus, the damping sheet 83 reciprocally displaced transmits and extrudes the air in the mounting hole, thereby accelerating the air flow speed in the area where the support frame plate 85 is located, optimizing the self-heat dissipation effect of the support frame plate 85, and prolonging the service life of the support frame plate 85.

[0041] In use, considering the possibility that the meshing vibration gradually increases due to structural wear during the meshing transmission of the four gear parts 43, the buffer assembly 8 supported by the reinforcing frame 7 buffers the gear part 43, and the specific principle is as follows:

[0042] The damping ball 82 inside the buffer assembly 8 is in contact with the surface of the corresponding gear body 432 under the support of the corresponding arc-shaped ring plate 81. Subsequently, during the reciprocating rotation transmission of the gear body 432, the damping ball 82 synchronously rotates and rubs, thereby frictionally dissipating energy and buffering the vibration generated by the operation of the gear body 432.

[0043] While the damping ball 82 rolls, the damping sheet 83 in contact with the damping ball 82 is synchronously pressed and moved to operate the damping spring 84, thereby sufficiently improving the damping effect on the gear member 43 in the working state, improving the stability of the operation, and reducing the noise generated by the meshing vibration.
