DETAILED DESCRIPTION

[0028] For further elaborating a banknote separating device and a method for fixing a one-way bearing of a reverse wheel set of the banknote separating device according to the present application, an embodiment of the present application is described in detail in conjunction with drawings.

[0029] The banknote separating device according to this embodiment includes a banknote separating wheel set and a reverse wheel set cooperating with the banknote separating wheel. Since the banknote separating device according to this embodiment is characterized in the reverse wheel set, only the structure of the reverse wheel set is described in detail in this embodiment. Referring to FIGS. 2 to 5, the reverse wheel set 10 includes a reverse-wheel-set rotating shaft 11, a reverse wheel fixing frame 12 and a reverse wheel assembly 17. One end of the reverse wheel assembly 17 sequentially passes through an E-shaped snap ring 13, a flanged bearing 14, a one-way bearing stop ring 15 and a one-way bearing 16 to be mounted to the reverse wheel fixing frame 12. Another end of the reverse wheel assembly 17 sequentially passes through an E-shaped snap ring 13, a flanged bearing 14 and a spacer 18 to be mounted to the reverse wheel fixing frame. The one-way bearing 16 and the reverse wheel fixing frame 12 are coupled by the one-way bearing stop ring 15 to form a stationary rigid body, and the one-way bearing stop ring 15 is in contact with only an outer ring of the flanged bearing 14.

[0030] In this embodiment, as shown in FIGS. 6 and 7, an outer peripheral surface of the one-way bearing stop ring 15 is provided with a protruding strip 151 extending in an axial direction of the one-way bearing stop ring, and the reverse wheel fixing frame 12 is provided with a groove 121 for fitting with the protruding strip. In an assembled state, as shown in FIG. 4, the protruding strip 151 of the one-way bearing stop ring 15 is embedded into the groove 121 of the reverse wheel fixing frame 12. One end of the protruding strip 151 protrudes from a first side of the one-way bearing stop ring 15, and an outer peripheral surface of the one-way bearing 15 is provided with a groove 161 for fitting with the protruding strip 151, as shown in FIG. 8. In an assembled state, the one-way bearing 16 is located at the first side of the one-way bearing stop ring 15, and the end, protruding from the first side of the one-way bearing stop ring 15, of the protruding strip 151 is embedded into the groove 161 in the outer peripheral surface of the one-way bearing 16. With the arrangement of the protruding strip 151, the one-way bearing stop ring 15 couples the one-way bearing 16 and the reverse wheel fixing frame 12 to form the stationary rigid body. The design of the protruding strip may be equivalently varied, which is not limited to the structure illustrated in the drawings.

[0031] In addition, the one-way bearing stop ring 15 includes a second side opposite to the first side, and an outer peripheral portion at the second side is configured as a flange 152. In an assembled state, the flanged bearing 14 is located at the second side of the one-way bearing stop ring 15, and the flange 152 is in contact with the outer ring of the flanged bearing 14, and reference may be made to FIG. 4. The flanged bearing 14 includes an inner ring 141 and an outer ring 142, as shown in FIG. 9. With the design of the flange 152, the one-way bearing stop ring 15 is in contact with the outer ring of the flanged bearing 14.

[0032] In this embodiment, the reverse-wheel-set rotating shaft 11, the reverse wheel fixing frame 12, the one-way bearing stop ring 15, the one-way bearing 16 and the outer ring 142 of the flanged bearing constitute a stationary end. The reverse wheel shaft assembly 17, the E-shaped snap ring 13 and the inner ring 141 of the flanged bearing constitute a movable end. The reverse wheel assembly 17 can only rotate in a direction opposite to a banknote-feeding direction under the action of the one-way bearing 16. Under the action of the flange 152, the one-way bearing stop ring 15 is in contact with only the outer ring of the flanged bearing 14, which allows the stationary end to be separated from the movable end by using the principle that the movements of the inner ring and the outer ring of the flanged bearing 14 are separated, thus, no friction is generated between the stationary end and the movable end, which ensures a free and smooth rotation of the reverse wheel assembly 17, thereby improving the service life of the banknote separating device and ensuring the reliability of its function.

[0033] The above description is only preferred embodiments of the present application. It should be noted that, the above preferred embodiments should not be deemed as a limitation to the present application, and the scope of the present application is defined by the claims of the present application. For the person skilled in the art, several improvements and modifications may be made to the present application without departing from the spirit and scope of the present application, and these improvements and modifications are also deemed to fall into the scope of the present application.
