Description

Technical Field

[0001] This utility model relates to the field of sprocket technology, specifically to a sprocket with good rust prevention performance. Background Technology

[0002] In mechanical transmission, sprockets are a common transmission component widely used in various mechanical equipment, such as bicycles, motorcycles, and industrial machine tools, where power is transmitted through the meshing of sprockets and chains. In practical use, sprockets often face humid, watery, or corrosive environments. For example, in agricultural and construction machinery operating outdoors, sprockets are susceptible to corrosion from rain and dew; in the chemical and food processing industries, sprockets may come into contact with various chemical liquids or damp materials.

[0003] When water remains on the surface of a sprocket, the oxygen and impurities in the water will react chemically with the metal material of the sprocket, causing it to rust. Rusting not only affects the appearance of the sprocket, but also reduces its mechanical performance. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] This invention provides a sprocket with good rust prevention performance, solving the problems mentioned in the background art.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a sprocket with good rust prevention performance, comprising a toothed disc and multiple teeth, wherein a shaft connection hole and several auxiliary connection holes are formed in the middle of the toothed disc, and the multiple teeth are uniformly formed on the outer edge of the shaft connection hole along the radial direction of the toothed disc, and further comprising multiple guide channels formed between the toothed disc and the teeth, wherein the guide channels include inter-tooth channels and toothed disc channels, wherein the inter-tooth channels are configured as straight channels, and the toothed disc channels are configured as circular openings, wherein the inter-tooth channels are opened at the tooth base of two adjacent teeth, and the toothed disc channels are opened on the toothed disc, and the inter-tooth channels and toothed disc channels are interconnected, and the inter-tooth channels and toothed disc channels penetrate the teeth and the toothed disc.

[0008] Preferably, the sprocket with good rust prevention performance further includes a second toothed disc reinforcement and multiple deflector blades. The second toothed disc reinforcement is formed on one side end face of the toothed disc, and the multiple deflector blades are formed on the outer edge of the second toothed disc reinforcement. The multiple deflector blades are distributed at equal intervals along the radial direction of the toothed disc, and the end of the deflector blade away from the second toothed disc reinforcement extends to the space between two adjacent toothed disc channels.

[0009] In a further preferred embodiment, the sprocket with good rust prevention properties also includes a first toothed disc reinforcement portion, which is formed on the other end face of the toothed disc.

[0010] In a further preferred embodiment, the sprocket with good rust prevention performance also includes a set of reinforcing ribs. The set of reinforcing ribs is formed on the outer edge of the first toothed disc reinforcement and extends to the root of the tooth at one end away from the first toothed disc reinforcement. The set of reinforcing ribs includes a number of reinforcing ribs equal to the number of guide channels. Each reinforcing rib covers an adjacent guide channel and is penetrated by the adjacent guide channel.

[0011] (III) Beneficial Effects

[0012] Compared with the prior art, this utility model provides a sprocket with good rust prevention performance, which has the following beneficial effects:

[0013] In this invention, the sprocket features multiple guide channels composed of inter-tooth channels and toothed disc channels. These channels effectively remove residual water between the teeth during sprocket rotation, reducing the contact time between water and the sprocket's metal surface. This effectively prevents oxygen and impurities in the water from reacting chemically with the metal, thus reducing the risk of rust at the source. Furthermore, the baffles disturb the surrounding airflow during sprocket rotation, allowing the airflow to act on the sprocket surface. Under the influence of the airflow, residual water on the sprocket surface is more easily blown off, further reducing the time water remains on the sprocket surface. Moreover, the inclusion of the first toothed disc reinforcement, the reinforcing rib group, and the second toothed disc reinforcement further enhances the overall strength of the sprocket and reduces damage caused by stress concentration.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1 and Figure 2 A sprocket with good rust prevention performance may include a toothed disc 10, multiple teeth 20, multiple flow channels 30, a first toothed disc reinforcement 40, a reinforcement rib group 50, a second toothed disc reinforcement 60, and multiple turbulence blades 70.

[0019] Similar to a conventional sprocket, the toothed disc 10 has a shaft connection hole 11 and several auxiliary connection holes 12 formed in the middle, allowing it to be connected to a drive device. Multiple teeth 20 are evenly formed radially on the outer edge of the shaft connection hole 11 along the toothed disc 10 and are used to cooperate with the chain for transmission.

[0020] In this embodiment, multiple flow channels 30 are formed between the gear disk 10 and the gear teeth 20, and each flow channel 30 includes an inter-tooth channel 31 and a gear disk channel 32. The inter-tooth channel 31 is a straight channel and is formed at the bottom of two adjacent gear teeth 20; the gear disk channel 32 is a circular opening and is formed on the gear disk 10. The inter-tooth channel 31 and the gear disk channel 32 are interconnected and penetrate through the gear teeth 20 and the gear disk 10. Water accumulated between adjacent gear teeth 20 can flow into the gear disk channel 32 through the inter-tooth channel 31, and as the sprocket rotates, the water in the gear disk channel 32 can be thrown out, thereby actively reducing the accumulation of water on the sprocket, especially between the gear teeth 20.

[0021] In this embodiment, to reduce the impact of multiple flow channels 30 on the sprocket strength, a first toothed disc reinforcement 40 is formed at the center of one side end face of the toothed disc 10, and a reinforcement rib group 50 is formed on the outer edge of the first toothed disc reinforcement 40, with the end of the reinforcement rib group 50 away from the first toothed disc reinforcement 40 extending to the root of the tooth 20. The first toothed disc reinforcement 40 can effectively disperse and bear the load from the shaft. It increases the metal cross-sectional area of ​​the central region, improving the bending and torsional resistance of this region, allowing the sprocket to maintain better structural stability when subjected to external forces. The reinforcement rib group 50 includes a number of reinforcement ribs equal to the number of flow channels 30, with each reinforcement rib covering and penetrating the adjacent flow channel 30. The presence of the reinforcement rib group 50 allows stress to be dispersed along the direction of the ribs, avoiding excessive stress concentration in local areas. It redistributes the stress originally concentrated near the flow channels to the entire sprocket structure, improving the overall load-bearing capacity of the sprocket.

[0022] In this embodiment, a second toothed disk reinforcement portion 60 is formed at the center of the end face of the toothed disk 10 facing away from the first toothed disk reinforcement portion 40. The second toothed disk reinforcement portion 60 can also be used to improve the overall strength of the toothed disk 10. Multiple segments of baffles 70 are formed on the outer edge of the second toothed disk reinforcement portion 60, and the multiple segments of baffles 70 are distributed at equal intervals along the radial direction of the toothed disk 10. The end of the baffle 70 away from the second toothed disk reinforcement portion 60 extends to the space between two adjacent toothed disk channels 32. When the sprocket rotates, the baffles 70 will disturb the surrounding airflow, so that the airflow can act on the sprocket surface. Under the action of the airflow, the water remaining on the sprocket surface is more easily blown off, further reducing the residence time of the water on the sprocket surface.
