Sleeve shaft mechanism capable of eliminating gap and rotating separately

Abstract

The invention discloses a sleeve shaft mechanism capable of eliminating clearance and rotating respectively, which comprises a primary transmission shaft and a fixed shaft sleeve, the primary transmission shaft is connected with the fixed shaft sleeve through a bearing C, and a clearance eliminating elastic sheet is arranged at the joint of the primary transmission shaft and the fixed shaft sleeve. According to the sleeve shaft mechanism capable of eliminating the gap and rotating respectively, a first-stage transmission shaft and a fixed shaft sleeve are connected through a bearing, a gap eliminating elastic piece A is additionally arranged between the first-stage transmission shaft and the fixed shaft sleeve, constant-pressure pre-tightening is achieved, and axial leaping of the first-stage transmission shaft is eliminated; a second-stage transmission shaft is connected with the first-stage transmission shaft through a bearing D and a bearing B, and constant-pressure pre-tightening is achieved through a gap eliminating elastic piece B; and the third-stage transmission shaft is connected with the second-stage transmission shaft through a bearing E and a bearing A, fixed pressure and pre-tightening are conducted through an anti-backlash elastic piece C, locking is conducted through a locking nut, axial jumping of the third-stage transmission shaft is prevented, the space is saved, the cost is saved, and the device is suitable for being widely popularized and used.

Description

technical field [0001] The invention relates to the technical field of winding machines, in particular to a sleeve shaft mechanism that eliminates gaps and can rotate separately. Background technique [0002] According to the classification of different industries, winding machines include: lithium battery winding machine, capacitor winding machine, textile winding machine, etc., among which lithium battery winding machine performs winding operation on battery cells. [0003] At present, during the winding process of lithium battery cells, each winding station is required to be switched, and the rotating power needs to be provided separately. Now most of the helical gears are used to provide power for the three stations, which takes up a lot of space and has a large moment of inertia. The axial movement is relatively large, and the structural requirements for the connecting support parts are relatively high. Contents of the invention [0004] The technical problem to be s...
