Problems solved by technology

[0002] The drive of the compact shelf has been driven by a sprocket mechanism for a long time, that is, in addition to the power source output as a sprocket, the relevant transmission device connected with the driving wheel shaft and other transmissions is also a sprocket drive; but the sprocket drive mechanism On the one hand, the structure is complex, on the other hand, due to its unreasonable transmission mode, especially its relatively low transmission efficiency and weak power transmission

In addition, it is easy to lose the chain during operation, the transmission noise is large, the service life is short, the work reliability is low, the operation failure rate is high, and the maintenance and repair workload is large.

In addition, when the driving load is slightly larger, the problems of chain jump and chain breakage will easily occur, which will affect the normal use of the compact rack

In response to this situation, those skilled in the art have tried to improve the implementation of driving and walking with a full gear transmission mechanism; however, due to the complexity and inexhaustibility of the arrangement structure of the relevant transmission gear mechanism of its driving device, the composition of the power transmission structure and the corresponding transmission connection mode Reasonable, if all the transmission gears and / or travel wheels of the power output are directly installed on the frame body, on the one hand, the installation of the travel gear driving device is difficult, and the processing accuracy of the relevant components is high, and the installation accuracy is high; On the other hand, the failure rate of the compact rack is high, especially because the bottom frame of the compact rack is prone to deformation. The increase of the matching error and the corresponding increase of the matching gap will not only make the transmission performance worse, the transmission efficiency will be lower, the service life will be shortened, and the reliability and stability will be relatively poor; especially, it will cause the transmission gears to be prone to bite Dead phenomenon, resulting in unstable walking operation of the compact rack, or causing the compact rack to fail to operate normally

Thereby, the replacement of the sprocket drive structure by the gear drive structure of the compact rack transmission device has not yet been able to be implemented, that is, it has not been successfully implemented so far.
