Abstract
Description
Technical Field
[0001] This utility model relates to pulleys, specifically a pulley with a heat dissipation structure. Background Technology
[0002] Friction occurs between the belt and pulley during use, generating significant heat that raises the belt's temperature. Once the belt reaches a certain temperature, it will be damaged or break. Currently, cooling fans are added to the pulleys to dissipate heat, but this adds to the equipment's workload, and since the fans only dissipate heat externally, the heat inside the pulley remains trapped. Utility Model Content
[0003] To address the shortcomings of the prior art, this invention provides a pulley with a heat dissipation structure. This invention features multiple heat dissipation grooves on the outer surface of the pulley rim and within the belt groove, enabling heat dissipation from the outside and also dissipating internal heat, thus improving the heat dissipation effect without increasing the burden on the equipment.
[0004] To achieve the above technical objectives, the present invention adopts the following technical solution: a pulley with a heat dissipation structure, comprising a body, wherein the body is provided with a plurality of belt grooves, the belt grooves are fitted with a wheel rim, the outer surface of the wheel rim is provided with a first heat dissipation hole and a third heat dissipation hole, the belt grooves are provided with a second heat dissipation hole, the body is provided with a first weight reduction groove and a second weight reduction groove along the axial direction, the first heat dissipation hole is connected to the first weight reduction groove, and the third heat dissipation hole is connected to the second weight reduction groove.
[0005] The first heat dissipation hole is a cylindrical hole, and the first heat dissipation holes are evenly distributed around the circumference. The first heat dissipation hole includes hole one and hole two, and both hole one and hole two are connected to the first weight reduction groove.
[0006] The included angle between hole one and hole two is 60°.
[0007] The second heat dissipation hole is a cylindrical hole, and the second heat dissipation holes are evenly distributed around the circumference.
[0008] Both the first and second weight-reducing grooves are cylindrical holes, and they are evenly distributed around the circumference.
[0009] The first weight-reducing groove is located outside the second weight-reducing groove and is offset from it.
[0010] In summary, this utility model achieves the following technical effects: This invention features multiple heat dissipation grooves on the outer surface of the wheel rim and inside the belt groove. The first heat dissipation hole 21 is connected to the first weight reduction groove, and the third heat dissipation hole is connected to the second weight reduction groove. This increases the airflow performance and speed, thereby improving the heat dissipation effect. The first and third heat dissipation holes in the belt groove are staggered, as are the first and second weight reduction grooves, increasing the heat dissipation position and effect. The weight reduction grooves can reduce weight and improve the heat dissipation effect. Attached Figure Description

Detailed Implementation
[0012] The present invention will be further described in detail below with reference to the accompanying drawings.
[0013] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
[0014] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
[0015] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.
[0016] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0017] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.
[0018] Example: Figure 1 It is a pulley with a heat dissipation structure. Figure 2 yes Figure 1 The main view, Figure 3 yes Figure 2 A schematic diagram of the cross-section along the BB direction. Figure 4 yes Figure 2 A cross-sectional view along the CC direction shows a body 1, which has multiple belt grooves 11. Each belt groove 11 is fitted with a wheel rim 12. The outer surface of the wheel rim 12 has a first heat dissipation hole 21 and a third heat dissipation hole 25. Each belt groove 11 has a second heat dissipation hole 23. The body 1 has a first weight reduction groove 22 and a second weight reduction groove 24 along the axial direction. The first heat dissipation hole 21 is connected to the first weight reduction groove 22, and the third heat dissipation hole 25 is connected to the second weight reduction groove 24.
[0019] This invention features multiple heat dissipation grooves on the outer surface of the wheel rim and within the belt groove. The first heat dissipation hole 21 is connected to the first weight reduction groove 22, and the third heat dissipation hole 25 is connected to the second weight reduction groove 24. This increases airflow and speed, improving heat dissipation. The first heat dissipation hole 21 and the third heat dissipation hole 25 in the belt groove are staggered, as are the first weight reduction groove 22 and the second weight reduction groove 24. This increases the heat dissipation position and effect. The weight reduction grooves can reduce weight and improve heat dissipation.
[0020] The first heat dissipation hole 21 is a cylindrical hole, and the first heat dissipation hole 21 is evenly distributed around the circumference. The first heat dissipation hole 21 includes hole one 210 and hole two 211, and both hole one 210 and hole two 211 are connected to the first weight reduction groove 22.
[0021] Hole 1 and Hole 2 are connected to the first weight-reducing groove, which can increase air circulation and dissipate heat quickly.
[0022] The angle between hole 210 and hole 211 is 60°, which disperses the two holes, enhancing heat dissipation and improving balance. Especially when the pulley rotates, the through-hole structure increases airflow speed, further improving heat dissipation.
[0023] The second heat dissipation hole 23 is a cylindrical hole, evenly distributed around its circumference. By placing the heat dissipation hole within the belt groove, heat can be directly dissipated, resulting in better performance. The second heat dissipation hole 23 does not contact the second weight-reduction groove 24 to prevent affecting operational performance.
[0024] Both the first weight-reducing groove 22 and the second weight-reducing groove 24 are cylindrical holes, and they are evenly distributed around the circumference.
[0025] The length of the third heat dissipation hole 25 is greater than the lengths of the first and second holes, and the included angle between adjacent third heat dissipation holes 25 is 60° to increase balance.
[0026] The first weight-reducing groove 22 is located outside the second weight-reducing groove 24 and is staggered. The staggered arrangement of the two allows for heat dissipation at different locations without affecting the overall strength of the wheel, making the wheel more uniform and stable.
[0027] The two weight-reducing slots are a through-body structure, serving two purposes: weight reduction and heat dissipation. Air circulates in the weight-reducing slots and heat dissipation holes, resulting in better heat dissipation.
[0028] The weight-reducing groove and heat dissipation hole of this utility model are both cylindrical, which reduces the difficulty of processing.
[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
