Description

Technical Field

[0001] The utility model relates to a fast combination structure of a toothed disc shaft and a transmission tooth, in particular to a fast combination structure of a toothed disc shaft and a transmission tooth for a fishing reel. Background Art

[0002] When designing and manufacturing fishing reels, the least amount of structures and parts should be used to achieve the same function. The simpler the structure and the fewer parts, the higher the reliability, the lower the production cost, and the higher the efficiency. Structurally, the transmission gear needs to be fixed on the sprocket shaft, and the rotation of the sprocket shaft is transmitted to other parts through the transmission gear. During production, the two need to be combined, and other matching parts are used to assist in axial positioning to achieve the result of stable transmission of rotation.

[0003] The existing technical solution is that the gear plate shaft and the transmission teeth are assembled together by axial sliding through the assembly surface, and the axial displacement is limited by the gap between the anti-wear gasket, the fixing plate, the bearing and the screw. This structure requires the provision of an anti-wear gasket to prevent friction caused by axial pressure between the transmission teeth and the fixing plate. Utility Model Content

[0006] Furthermore, the transmission tooth assembly section of the gear plate shaft is square, and the transmission gear shaft hole is a circular hole. Four protrusions are evenly distributed circumferentially in the middle of the circular hole to transform the circular hole into a square hole that matches the transmission tooth assembly section of the gear plate shaft, and the thickness of the protrusion is smaller than the thickness of the transmission tooth, and the right side of the protrusion is in contact with the left side of the limiting mechanism.

[0007] Furthermore, the limiting mechanism is a protrusion provided at the other end of the matching surface between the gear plate shaft and the transmission tooth.

[0008] Furthermore, a pit is formed between the protrusion and the positioning surface, and the transmission tooth is arranged in the pit.

[0009] Furthermore, the protrusion is in the form of an inclined surface, and the thickness of the protrusion is thinner on the right and thicker on the left.

[0010] The utility model adopts the above structure to achieve the following beneficial effects: the utility model provides a fishing reel sprocket shaft and transmission tooth quick connection structure, by arranging a limit device on the sprocket shaft to limit the axial displacement of the transmission tooth, removes the anti-wear gasket mechanism, and simplifies the fishing reel structure.

[0017] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0018] Aiming at the needs of a sprocket shaft and a transmission tooth for a fishing reel, the designer of the utility model innovatively proposes a sprocket shaft and a transmission tooth quick-combination structure for a fishing reel, which can limit the axial displacement of the transmission tooth.

[0019] like Figures 1 to 4As shown, a quick-combination structure of a sprocket shaft 1 and a transmission tooth 2 for a fishing reel comprises a sprocket shaft 1 and a transmission tooth 2 mounted on the sprocket shaft 1, a fixing plate 3, a bearing 4 and a screw 5, wherein one end of a transmission tooth assembly section 13 of the sprocket shaft 1 is provided with an axial positioning surface 6 in contact with a side surface of the transmission tooth 2, and is characterized in that at least one limiting mechanism 7 is axially provided at the other end of the transmission tooth assembly section 13 of the sprocket shaft 1, the transmission tooth 2 is arranged between the axial positioning surface 6 and the limiting mechanism 7, and forms a combined part with the transmission tooth assembly section 13 of the sprocket shaft 1, and in this embodiment, two limiting mechanisms 7 are provided at the other end of the transmission tooth assembly section 13 of the sprocket shaft 1, and are axially symmetrically arranged.

[0020] The transmission tooth assembly section 13 of the gear plate shaft 1 is square and has a chamfered angle. The shaft hole of the transmission tooth 2 is a circular hole 8. Four protrusions 9 are evenly distributed circumferentially in the middle of the circular hole 8 to transform the circular hole 8 into a square hole 14 that matches the transmission tooth assembly section 13 of the gear plate shaft 1. The thickness of the protrusion 9 is less than the thickness of the transmission tooth 2. The right side of the protrusion 9 contacts the left side of the limiting mechanism 7, which can limit the radial movement of the gear plate shaft 1 and the transmission tooth 2 and limit the release of the combined state.

[0021] The limiting mechanism 7 is a protrusion 10 provided at the other end of the matching surface between the gear plate shaft 1 and the transmission tooth 2, which has a simple structure and is easier to achieve limiting.

[0022] A recess 11 is formed between the protrusion 10 and the positioning surface, and the transmission tooth 2 is disposed in the recess 11 .

[0023] The protrusion 10 is in the form of an inclined surface 12 , and the thickness of the protrusion 10 is thinner on the right and thicker on the left, so that the driving gear 2 can slide into the driving gear assembly section 13 on the gear plate shaft 1 .

[0024] During assembly, the transmission tooth 2 is axially slid through the square hole 14 and slides into the transmission tooth assembly section 13 of the gear plate shaft 1 from the limiting mechanism 7 until the side of the transmission tooth 2 contacts the axial positioning surface 6. The transmission tooth 2 is assembled in the pit 11 to limit the axial movement of the transmission tooth 2 and is combined with the gear plate shaft 1 to form a combined part. The transmission tooth assembly section 13 of the gear plate shaft 1 is square and cooperates with the square hole 14 of the transmission tooth 2 to limit the radial movement of the gear plate shaft 1 and the transmission tooth 2. The limiting mechanism 7 limits the gear plate shaft 1 and the transmission tooth 2 from being released from the combined state.

[0025] The utility model adopts the above structure to achieve the following beneficial effects: the utility model provides a fishing reel sprocket shaft and transmission tooth quick connection structure, by arranging a limit device on the sprocket shaft to limit the axial displacement of the transmission tooth, removes the anti-wear gasket mechanism, and simplifies the fishing reel structure.

[0026] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
