Bank note distributing device and reversing wheel set thereof

Abstract

The invention relates to a bank note distributing device. The bank note distributing device is applied to financial self-service equipment and comprises a bank note distributing wheel set and a reversing wheel set matched with the bank note distributing wheel set, wherein the reversing wheel set comprises a reversing wheel set rotating haft, a reversing wheel fixing frame and a reversing wheel set body; one end of the reversing wheel set body is arranged on the reversing wheel fixing frame through an E-shaped ring, a bearing with a flange, a unidirectional bearing limit ring and a unidirectional bearing sequentially; the unidirectional bearing ring links the unidirectional bearing and the reversing wheel fixing frame into a static rigid body; the unidirectional bearing limit ring is only in contact with the outer ring of the bearing with the flange. Due to the fact that the unidirectional bearing limit ring is only in contact with the outer ring of the bearing with the flange, and the principle that the inner ring and the outer ring of the bearing with the flange are separated is used, a static end and a moveable end are separated, mutual friction between the static end and the moveable end does not exist, free smooth rotation of the reversing wheel set is guaranteed, the service life of the bank note distributing device is prolonged, and the function reliability of the bank note distributing device is guaranteed.

Description

technical field [0001] The invention relates to the technology of financial self-service equipment, in particular to a one-way bearing fixing method of a banknote dispensing device and its reversing wheel set. Background technique [0002] At present, one-way bearings are generally used in the banknote-separating mechanism of financial equipment, and its function is to limit the rotation of the banknote-separating reverse wheel along the banknote-feeding direction, and only allow it to rotate in the opposite direction to the banknote-feeding direction. [0003] At present, most of the one-way bearings are fixed using such as figure 1 In the manner shown, the reverse wheel set includes the rotary shaft of the reverse wheel 1, the fixed frame of the reverse wheel 2, the E-ring 3, the one-way bearing sleeve 4, the one-way bearing 5, the bearing with flange 6, the reverse wheel shaft Component 7 and gasket 8. The fixing method of the one-way bearing 5 can be understood as: the...

AI Technical Summary

Problems solved by technology

[0004] In this fixing method, since the end surface of the E-ring at the movable end will be in extrusion contact with the end surface of the one-way bearing 5 at the stationary end, frictional resistance will be generated, which will hinder the free rotation of the countershaft assembly 7. If the frictional resistance is too large , the reverse wheel assembly 7 cannot even rotate

The rotation of the reverse wheel assembly 7 is not smooth or unable to rotate, which will cause the rubber part of the reverse wheel assembly to be easily worn locally, and the banknote separation gap will become larger

This kind of defect will greatly shorten the service life of the banknote separating device, and the banknote separating gap needs to be adjusted frequently. If it is serious, it will lead to the failure of the banknote separating function, which cannot meet the design requirements.
