Description
Technical Field
[0001] This utility model relates to the field of fishing reel technology, and in particular to a speed reduction gear for fishing reels. Background Technology
[0002] During the use of fishing reels, the stability of the retrieval action and the durability of the reduction mechanism are key factors affecting the reel's performance. Existing fishing reels mostly employ traditional gear drives or conventional cycloidal reduction mechanisms for speed reduction; however, these mechanisms present the following problems in practical applications:
[0003] On the one hand, traditional deceleration mechanisms, due to limitations in gear ratio design, often result in rapid up-and-down movement of the spool during reeling. This can easily lead to uneven line tangling and fluctuating reeling force, affecting the fishing experience and catch efficiency. Especially when handling medium to large fish, excessively rapid up-and-down movement increases the risk of line breakage and reduces the reliability of the fishing reel.
[0004] On the other hand, in existing cycloidal reduction mechanisms, the contact method and force distribution between the cycloidal gear and related mating parts are not reasonable enough. After long-term use, excessive wear is likely to occur, which will not only shorten the service life of the reduction mechanism, but may also lead to a decrease in transmission accuracy and affect the overall performance of the fishing reel.
[0005] Therefore, it is necessary to design a speed reduction gear for fishing reels to solve the above problems. Utility Model Content
[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a deceleration gear for fishing reels. Through the setting of the deceleration component, this invention causes the main shaft to move up and down at a slower speed when the rocker arm rotates to retrieve the line, thereby allowing the fishing line to be wound more neatly on the reel, making the transmission more stable, and better adapting to the needs of lure fishing for fast response and precise control.
[0007] To achieve the above objectives, the present invention adopts the following technical solution:
[0008] A fishing reel deceleration gear includes a main shell, a deceleration assembly inside the main shell, a rotating gear, an eccentric circular hole inside the rotating gear, a cycloidal gear installed in the eccentric circular hole, a plurality of cylindrical blocks fixedly connected to the front side of the cycloidal gear, a cover plate inside the rotating gear, a plurality of through holes on the cover plate, each cylindrical block passing through a corresponding through hole, a pinwheel fixing seat installed on the left inner wall of the main shell, the pinwheel fixing seat located inside the rotating gear, a cycloidal groove provided on the right side of the pinwheel fixing seat, and a cycloidal tooth fixedly connected to the left side of the cycloidal gear, the cycloidal tooth located in the cycloidal groove.
[0009] Preferably, a one-way cover is fixedly connected to the upper end of the main shell, a main shaft passes through the one-way cover, and an louver is provided above the one-way cover.
[0010] Preferably, a slider is mounted on the lower end of the main shaft by a fixing screw, a fixing head is fixedly connected to the right side of the cover plate, a connecting groove that mates with the fixing head is provided on the left side of the slider, the right side of the fixing head extends into the connecting groove, and two guide rods are vertically fixedly connected inside the main housing. Both guide rods pass through the slider, and the slider is slidably connected to the two guide rods.
[0011] Preferably, the deceleration assembly is installed in the main housing by bolts, a threaded sleeve is fixed to the left inner wall of the main housing, the pin wheel fixing seat is sleeved on the outer wall of the threaded sleeve, the bolt is threadedly connected to the threaded sleeve, the bolt passes through the cover plate and the cycloidal gear, the outer wall of the pin wheel fixing seat is provided with three limiting grooves, the left inner wall of the main housing is provided with an installation groove, and the pin wheel fixing seat is located in the installation groove.
[0012] Preferably, a shaft core is rotatably connected through two first bearings inside the main housing. A gear body that meshes with a rotating gear is mounted on the shaft core. A helical gear is sleeved on the main shaft. The helical gear is rotatably connected to a one-way cover through a second rotating shaft. A crown gear that meshes with the helical gear is mounted on the shaft core. The helical gear is fixedly connected to the lower end of the louver.
[0013] Preferably, the plurality of cylindrical blocks and through holes are arranged in a ring array.
[0014] Compared with existing technologies, the advantages of this device are:
[0015] 1. Compared with the existing technology, this device forms a more compact deceleration component by meshing the cycloidal gear and the rotating gear, combined with the limiting and guiding of the cycloidal teeth and the cycloidal groove, and the linkage design of the cylindrical block and the through hole. The overall structure is simplified, effectively reducing the space occupied. At the same time, it will not wear too much while performing cycloidal deceleration, greatly extending the overall service life of the fishing reel.
[0016] 2. Compared with existing technologies, this device utilizes the characteristics of cycloidal pinwheel transmission to maintain a stable reduction ratio during high-frequency line winding and unwinding. Through the synergistic effect of the reduction components, the up-and-down movement speed of the main shaft can be precisely controlled to perfectly match the rotation speed of the line wheel, ensuring that the fishing line is neatly wound. This avoids problems such as line accumulation and knotting caused by unstable reduction ratios in traditional mechanisms, significantly improving the smoothness and reliability of line winding.

Detailed Implementation
[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0026] Reference Figures 1-7A fishing reel speed reduction gear includes a main housing 1, within which a speed reduction assembly is provided. The speed reduction assembly includes a rotating gear 12, which has an eccentric circular hole whose center does not coincide with the center of the rotating gear 12, providing a mounting base for the eccentric movement of a cycloidal gear 16. The cycloidal gear 16 is installed within the eccentric circular hole and can rotate eccentrically under the drive of the eccentric circular hole. Multiple cylindrical blocks 17 are fixedly connected to the front side of the cycloidal gear 16. A cover plate 13 is provided inside the rotating gear 12, and the cover plate 13 has multiple through holes 18, the radius of which is larger than that of the cylindrical blocks. With a radius of 17, each cylindrical block 17 passes through a corresponding through hole 18. A pinwheel fixing seat 15 is installed on the inner left side of the main shell 1. The pinwheel fixing seat 15 is fixed in position, providing a base for the movement of the cycloidal gear 16. The pinwheel fixing seat 15 is located inside the rotating gear 12. A cycloidal groove is provided on the right side of the pinwheel fixing seat 15. A cycloidal tooth is fixedly connected to the left side of the cycloidal gear 16. The cycloidal tooth is located in the cycloidal groove. The cycloidal tooth and the teeth in the cycloidal groove cooperate with each other to achieve meshing transmission when the cycloidal gear 16 makes an eccentric motion. The multiple cylindrical blocks 17 and through holes 18 are distributed in a ring array.
[0027] The main housing 1 has a one-way cover 3 fixedly connected to its upper end. A main shaft 4 passes through the one-way cover 3 and is slidably connected to the one-way cover 3. During production, the thread reel is installed on the main shaft 4. A louver 2 is provided above the one-way cover 3. A shaft core 5 is rotatably connected inside the main housing 1 through two first bearings 6. A gear body 14 that meshes with a rotating gear 12 is installed on the shaft core 5. When the gear body 14 rotates, it can drive the rotating gear 12 to rotate, thereby realizing power transmission. A helical gear 8 is sleeved on the main shaft 4. The helical gear 8 is rotatably connected to the one-way cover 3 through a second rotating shaft. A crown gear 7 that meshes with the helical gear 8 is installed on the shaft core 5. The helical gear 8 is fixedly connected to the lower end of the louver 2, which can change the direction of power transmission and transmit the rotation of the shaft core 5 to the louver 2, causing the louver 2 to rotate.
[0028] The lower end of the main shaft 4 is fitted with a slider 10 by a fixing screw 11. A fixing head 19 is fixedly connected to the right side of the cover plate 13. The left side of the slider 10 is provided with a connecting groove that mates with the fixing head 19. The right side of the fixing head 19 extends into the connecting groove, so that the movement of the cover plate 13 can be transmitted to the slider 10 through the fixing head 19, causing the slider 10 to move up and down. Two guide rods 9 are vertically fixedly connected inside the main housing 1. Both guide rods 9 pass through the slider 10. The slider 10 is slidably connected to the two guide rods 9, ensuring that the slider 10 can only move in a straight line in the vertical direction along the guide rods 9, thereby ensuring the stability of the movement of the main shaft 4.
[0029] The deceleration assembly is bolted into the main housing 1. The bolt connection facilitates the installation, disassembly, and maintenance of the deceleration assembly. A threaded sleeve is fixed to the inner left side of the main housing 1. The pin wheel fixing seat 15 is fitted onto the outer wall of the threaded sleeve. The bolt is threadedly connected to the threaded sleeve and passes through the cover plate 13 and the cycloidal gear 16. The outer wall of the pin wheel fixing seat 15 is provided with three limiting grooves. The inner left side of the main housing 1 is provided with an installation groove. The shape of the installation groove matches the shape of the pin wheel fixing seat 15. The pin wheel fixing seat 15 is located in the installation groove. The limiting grooves cooperate with the protrusions in the installation groove to further restrict the rotation of the pin wheel fixing seat 15 and ensure its fixed position.
[0030] The functional principle of this utility model can be explained through the following operation: When the fishing reel is reeling in the line, power is transmitted to the reduction assembly through the gear body 14. At this time, the rotating gear 12 starts to rotate inside the main housing 1, and the eccentric circular hole inside it drives the cycloidal gear 16 to perform eccentric motion. Since the cycloidal teeth on the left side of the cycloidal gear 16 are located in the cycloidal groove of the needle wheel fixing seat 15, the cycloidal teeth and the cycloidal groove form a meshing transmission during the eccentric motion, thereby achieving first-stage reduction.
[0031] When the cycloidal gear 16 rotates, the cylindrical block 17 on its front side drives the cover plate 13 to move synchronously through the through hole 18 on the cover plate 13. The fixing head 19 on the right side of the cover plate 13 is embedded in the connecting groove of the slider 10, thereby pushing the slider 10 to make linear reciprocating motion along the guide rod 9. The movement of the slider 10 drives the main shaft 4 to move up and down, while the crown gear 7 drives the helical gear 8 to rotate, thereby driving the louver to rotate, so that the fishing line is wound on the reel installed on the main shaft 4. Due to the multi-stage transmission of the reduction assembly, the up and down movement speed of the main shaft 4 is significantly reduced, ensuring that the fishing line is wound evenly when reeling in the line.
[0032] Throughout the transmission process, the cycloidal gear 16 and the cycloidal groove of the pinwheel mounting seat 15 adopt a cycloidal meshing design, which, together with the sliding connection between the cylindrical block 17 and the through hole 18, reduces the rigid friction of traditional gear transmission, reduces the overall wear of the reduction assembly, and extends the service life of the fishing reel.
[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art can, within the technical scope disclosed in the present utility model, match the technical solution and utility model configuration of the present utility model. The needle wheel fixing seat 15 is located in the mounting groove, and the limiting groove cooperates with the protrusion in the mounting groove to further restrict the rotation of the needle wheel fixing seat 15 and ensure its position is fixed.
[0034] The functional principle of this utility model can be explained through the following operation: When the fishing reel is reeling in the line, power is transmitted to the reduction assembly through the gear body 14. At this time, the rotating gear 12 starts to rotate inside the main housing 1, and the eccentric circular hole inside it drives the cycloidal gear 16 to perform eccentric motion. Since the cycloidal teeth on the left side of the cycloidal gear 16 are located in the cycloidal groove of the needle wheel fixing seat 15, the cycloidal teeth and the cycloidal groove form a meshing transmission during the eccentric motion, thereby achieving first-stage reduction.
[0035] When the cycloidal gear 16 rotates, the cylindrical block 17 on its front side drives the cover plate 13 to move synchronously through the through hole 18 on the cover plate 13. The fixing head 19 on the right side of the cover plate 13 is embedded in the connecting groove of the slider 10, thereby pushing the slider 10 to make linear reciprocating motion along the guide rod 9. The movement of the slider 10 drives the main shaft 4 to move up and down, while the crown gear 7 drives the helical gear 8 to rotate, thereby driving the louver to rotate, so that the fishing line is wound on the reel installed on the main shaft 4. Due to the multi-stage transmission of the reduction assembly, the up and down movement speed of the main shaft 4 is significantly reduced, ensuring that the fishing line is wound evenly when reeling in the line.
[0036] Throughout the transmission process, the cycloidal gear 16 and the cycloidal groove of the pinwheel mounting seat 15 adopt a cycloidal meshing design, which, together with the sliding connection between the cylindrical block 17 and the through hole 18, reduces the rigid friction of traditional gear transmission, reduces the overall wear of the reduction assembly, and extends the service life of the fishing reel.
[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
