[0002] The drive transmission mechanism of the compact shelf bookshelf has long used the relatively long axis that is close to the column length of the compact shelf bookshelf or longer than the distance between the walking wheels at both ends of the compact shelf bookshelf as the main drive shaft for power transmission. This long main drive shaft structure And the transmission method, on the one hand, the long main drive shaft itself is difficult to process, requires high machining accuracy, large axial deformation, and large axial torsional deformation, especially on the other hand, the installation error of the long main drive shaft Large, installation accuracy requirements are particularly high, because the long main drive shaft usually has more than two installation fixed connection points, and three or more fixed connection points are difficult to ensure that each installation fixed connection point is on the same axis, therefore, its long The installation deformation of the main drive shaft will inevitably affect the straightness of the main drive shaft and the mutual parallelism of the drive and driven shafts, so as to affect the transmission efficiency, transmission performance and transmission effect. At the same time, it is easy to make the transmission of the main and driven shafts mesh The gears or sprockets have problems of mutual seizure or incomplete meshing, unreliability, and instability, which also increase power consumption needlessly. In severe cases, it will affect the normal operation of the compact rack, or the speed of the opposite ends of the compact rack will be inconsistent.

[0003] In addition, the existing compact shelves and bookshelves have always adopted the long driving shaft structure and transmission mode whose cross-sectional shape is circular and whose length reaches the walking wheels at the opposite ends of the chassis. The power transmission also adopts the existing circular sprocket or meshing gear coupling transmission structure. Of course, it is also fixed on the chassis through the traditional and customary circular bearing device, and the circular shaft and the corresponding circular bearing device and Circular sprockets or gears are usually connected to each other by welding or / and fastening screws. The welding is easy to cause problems such as virtual welding, desoldering, and welding deformation, which seriously affects the reliability and stability of the transmission shaft and connection. Those connected by fasteners are more prone to loosening, slipping, and connection gaps, which also affect the transmission performance, transmission efficiency and reliability of the transmission shaft.
