Title:
SHAFT CONNECTING DEVICE AND LITHIUM BATTERY CELL WINDING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/196202
Kind Code:
A1
Abstract:
The present invention relates to the technical field of shaft connection and, in particular, to a shaft connecting device and a lithium battery cell winding system. The shaft connecting device comprises a first shaft (100) having a first hole (101) and a second shaft (200) sleeved on the first shaft (100) and having a second hole (201), wherein the diameter of the second hole (201) is larger than the diameter of the first hole (101), and the second hole (201) and the first hole (101) are in communication and form a step structure when the second shaft (200) is sleeved on the first shaft (100). The shaft connecting device further comprises a step positioning pin (310) clamped in the step structure and a fixing member (320) fixed to the second hole (201) and abutting against the step positioning pin (310). The shaft connecting device has the advantageous effects that compared with the prior art, the formed step structure reduces the thickness of the first shaft (100), and especially, can make the first shaft (100) form a hollow structure, thereby meeting the space requirement of a large amount of wiring in the hollow structure; and in addition, the shaft connecting device can be compatible with shafts of different sizes, thereby improving the applicability of the shaft connecting device.
