Banknote Separating Device and Its Reversing Wheel Set

Abstract

The invention relates to a banknote distributing device, which is applied to financial self-service equipment, and comprises a banknote dispensing wheel set and a reversing wheel set matched with the banknote dispensing wheel, and the reversing wheel set includes a reversing wheel A set of rotating shafts, a reverse wheel fixing frame and a reverse wheel assembly. One end of the reverse wheel assembly is installed on the On the fixed frame of the reverse wheel, wherein the one-way bearing limit ring connects the one-way bearing and the reverse wheel fixed frame into a static rigid body, and the one-way bearing limit ring is only connected with the flanged bearing The outer rings are in contact. Since the limit ring of the one-way bearing is only in contact with the outer ring of the bearing with flange, using the principle that the inner ring and outer ring of the bearing with flange are separated, the stationary end is separated from the movable end, so that the stationary end and the movable end are mutually There is no mutual friction between them, so as to ensure the free and smooth rotation of the reverse wheel assembly, so as to improve the service life of the banknote dispensing device and ensure the reliability of its function.

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.
