Compact shelf driving device

Abstract

The invention discloses a compact shelf driving device. The compact shelf driving device comprises a driving shaft, a driven shaft and corresponding driving gear and driven gear, wherein the driving shaft and the driven shaft are respectively arranged on a compact bottom shelf; the driving gear and the driven gear are respectively connected to the driving shaft and the driven shaft; the corresponding end of the driving shaft is connected with a shaft sleeve of which the cross section is polygonal in shape; the corresponding end of the driven shaft is provided with a corresponding prism which is correspondingly matched with the shaft sleeve, wherein the cross section of the prism is polygonal in shape; the driving shaft is connected with the driven shaft by the shaft sleeve of the driving shaft and the prism of the driven shaft. The compact shelf driving device is simple in composition and structure, reasonably matched with a transmission structure, stable and reliable in transmission and high in transmission efficiency.

Description

technical field [0001] The invention relates to a compact shelf. In particular, it relates to a compact rack transmission device. Background technique [0002] The transmission mechanism of the bottom frame of the existing compact shelf is not only relatively complex in structure, but also its transmission and matching methods are not reasonable. For example, the structure of the transmission shaft of the transmission mechanism and the transmission and cooperation methods with the corresponding matching component bushings are all traditional. The circular transmission shaft and the shaft sleeve of the seamless steel pipe are matched. The most prominent disadvantage of this matching structure and the corresponding transmission mode is that the compact rack is in the operation process due to the small frictional force of the mutual contact, and the transmission stability of the transmission shaft is poor. The force needs to be large, usually more than 8N, and after a long tim...

[0002] The transmission mechanism of the bottom frame of the existing compact shelf is not only relatively complex in structure, but also its transmission and matching methods are not reasonable. For example, the structure of the transmission shaft of the transmission mechanism and the transmission and cooperation methods with the corresponding matching component bushings are all traditional. The circular transmission shaft and the shaft sleeve of the seamless steel pipe are matched. The most prominent disadvantage of this matching structure and the corresponding transmission mode is that the compact rack is in the operation process due to the small frictional force of the mutual contact, and the transmission stability of the transmission shaft is poor. The force needs to be large, usually above 8N, and the coupling drive shaft and the corresponding bushing will slip after running for a long time or with a slightly larger load, resulting in idling and causing the transmission to fail
