Integrated dual bearing for fishing reel line cup

Abstract

This utility model belongs to the technical field of fishing tackle accessories and discloses an integrated double bearing for fishing reel spools. It includes an outer ring fixed to the fishing reel body; a first inner ring coaxially disposed within the outer ring, with balls between them forming a primary bearing; and a second inner ring coaxially disposed within the first inner ring, with balls between them forming a secondary bearing. The second inner ring is connected to and rotates with the fishing reel spool. When the spool begins to rotate, the secondary bearing operates. If resistance is encountered, the first inner ring of the primary bearing rotates relative to the outer ring to counteract the resistance, ensuring smooth rotation of the spool. This integrated double-ring bearing adds a small bearing inside what was originally a large bearing, transforming the nested double-ring bearing into a single unit. This ensures less radial and axial runout of the overall bearing and reduces the starting radius, resulting in a lower starting torque.

Description

Technical Field

[0001] This utility model relates to the field of fishing gear accessories technology, specifically to a bearing used in fishing reel spools. Background Technology

[0002] Fishing reels are the core equipment in fishing activities, and their performance directly affects casting distance, accuracy, and handling. The spool, as the part on the reel where the fishing line is wound, is crucial for its rotational flexibility. Currently, fishing reel spools generally use standard deep groove ball bearings to reduce rotational resistance. However, existing bearings have a relatively high starting torque, resulting in a slow spool response when casting lightweight lures. This prevents the spool from quickly reaching a high-speed rotation state, affecting casting distance. Furthermore, due to the slow starting torque and its own inertia, spools using standard bearings are prone to difficulty generating power, resulting in short casting distances, and even line tangling due to unstable rotation speed when casting small-weight lures. Utility Model Content

[0003] To solve the above technical problems, an integrated double bearing for fishing reel spools is provided.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: an integrated double bearing for a fishing reel spool, comprising,

[0005] The outer ring is fixed to the main body of the fishing vessel;

[0006] The first inner ring is coaxially arranged inside the outer ring, and ball bearings are arranged between the two to form a primary bearing.

[0007] The second inner ring is coaxially arranged inside the first inner ring, and ball bearings are arranged between the two to form a two-stage bearing;

[0008] The second inner ring is connected to the fishing reel spool and rotates with it. When the spool starts to rotate, the secondary bearing works. If it encounters resistance, the first inner ring of the primary bearing rotates relative to the outer ring to counteract the resistance and ensure that the spool can rotate smoothly.

[0009] According to this utility model, the outer ring, the first inner ring, and the second inner ring are all made of stainless steel.

[0010] According to this utility model, the ball bearing is made of silicon nitride ceramic material.

[0011] According to this utility model, the retainer is further made of engineering plastic or phenolic resin-insulated phenolic resin.

[0012] According to this utility model, the outer diameter of the outer ring is 10mm, the outer diameter of the first inner ring is 6.95mm, the outer diameter of the second inner ring is 4.1mm, the wall thickness of the first inner ring and the second inner ring is 0.55mm, and the overall thickness of the integrated double bearing is 4mm.

[0013] According to this utility model, the diameter of the ball is 1.2 mm; there are 16 balls distributed along the inner circumference.

[0014] According to this utility model, the outer diameter of the outer ring is 11mm, the outer diameter of the first inner ring is 8.4mm, the outer diameter of the second inner ring is 6mm, the wall thickness of the first inner ring and the second inner ring is 0.5mm, and the overall thickness of the integrated double bearing is 4mm.

[0015] According to this utility model, the diameter of the ball is 1.0 mm; there are 26 balls distributed along the inner circumference.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This utility model's integrated double-ring bearing adds a small bearing inside what was originally a large bearing, turning the original nested double-ring bearing into a single unit. This ensures that the radial and axial runout of the overall bearing is smaller; at the same time, it reduces the bearing's starting radius, resulting in a smaller starting torque.

[0018] This invention features a fixed outer ring and a rotating inner ring, with a reduced inner ring wall thickness. This reduces the overall weight of the spool during use, resulting in a faster start-up speed and higher rotation speed. This also increases the casting capacity for small-weight baits during fishing reel casting.

[0019] The present invention modifies the size of the internal balls of the bearing and increases their number, which will reduce the bearing's rotation radius, resulting in a faster starting speed and more stable rotation.

[0020] Because the silicon nitride ball bearing material has a relatively high roughness, it produces a unique hissing sound during high-speed rotation, increasing the enjoyment of casting and using the fishing reel.

[0021] Fishing reels are generally used in humid environments. The bearing inner and outer rings are made of stainless steel, the balls are made of silicon nitride, and the cage is made of nylon, which greatly increases the bearing's rust resistance and improves its overall service life.

[0025] Reference numerals: 1-Outer ring, 2-First inner ring, 3-Second inner ring, 4-Ball, 5-Cage. Detailed Implementation

[0026] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0027] like Figure 3 As shown in the embodiment of this application, an integrated double bearing for a fishing reel spool is disclosed, including an outer ring 1 and a first inner ring 2 coaxially disposed therein, with balls 4 disposed between the two. The balls 4 are limited by a cage 5 so that the balls 4 can be evenly distributed to form a primary bearing; it also includes a second inner ring 3 coaxially disposed within the first inner ring 2, with balls 4 also disposed between the two. The balls 4 are limited by a cage 5 to form a secondary bearing.

[0028] In practical applications, the outer ring 1 is fixed to the main body of the fishing reel. The second inner ring 3 is connected to the spool and rotates with it. When the spool begins to rotate, the secondary bearing is the primary force. If resistance is encountered, the primary bearing intervenes, allowing the first inner ring 2 to rotate relative to the outer ring 1, thereby counteracting the resistance and ensuring the spool can rotate smoothly and continuously. This dual support and assistance mechanism is key to achieving low starting torque and high stability.

[0029] In the above technical solution, the outer ring 1, the first inner ring 2, and the second inner ring 3 are all made of SU420, i.e., 4Cr13 stainless steel, to solve the problem of bearing rust. The first inner ring 2 and the second inner ring 3 are thinner, reducing the overall weight of the spool. With a lighter spool, the spool's starting speed is faster and its rotation speed is also faster, which increases the casting ability of small-weight baits during fishing reel casting.

[0030] The ball bearing 4 is made of silicon nitride ceramic material, which has high hardness, light weight, corrosion resistance and self-lubrication; the cage 5 can be made of engineering plastic such as PA66, which has good wear resistance and low coefficient of friction and does not rust; phenolic resin-insulated phenolic resin (FJ) can also be used.

[0031] In the embodiments of this application, such as Figure 1As shown, the outer diameter of the outer ring 1 is 10mm, the outer diameter of the first inner ring 2 is 6.95mm, the outer diameter of the second inner ring 3 is 4.1mm, the wall thickness of the first inner ring 2 and the second inner ring 3 is 0.55mm, and the overall thickness of the integrated double bearing is 4mm. The ball diameter is 1.2mm; 16 balls 4 are distributed along the circumference of the inner ring. Adjusting the wall thickness of the first inner ring 2 and the second inner ring 3 reduces the diameter of the balls 4, thus reducing the bearing's rotation radius, resulting in a faster starting speed and more stable bearing rotation.

[0032] In the embodiments of this application, such as Figure 2 As shown, the outer diameter of the outer ring 1 is 11 mm, the outer diameter of the first inner ring 2 is 8.4 mm, the outer diameter of the second inner ring 3 is 6 mm, the wall thickness of the first inner ring 2 and the second inner ring 3 is 0.5 mm, and the overall thickness of the integrated double bearing is 4 mm. The ball diameter is 1.0 mm; there are 26 balls 4 distributed along the circumference of the inner ring.

[0033] The beneficial effects of this invention are as follows: After the bearing of this invention is installed on the fishing reel spool, the spool should rotate without significant radial or axial runout, and the feel should be smooth; this represents the optimal state of structural stability. Furthermore, the inside of the bearing should be kept clean, free of dust, impurities, and moisture. Under these conditions, due to the high roughness of the silicon nitride ball bearing material, the bearing should rotate without any jamming or abnormal resistance, and should produce a crisp "hissing" sound during casting; this represents the optimal performance state.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
