Description

Technical Field

[0001] This utility model relates to the technical field of oil pumping unit accessories, specifically to an oil pumping unit pulley with fast heat dissipation. Background Technology

[0002] A pulley is a mechanical component used to transmit power. It typically consists of a rim, spokes, and a hub. Its working principle relies on the friction between the belt and the pulley to transmit power. The power source (such as an electric motor) drives the driving pulley to rotate, and the friction between the belt and pulley transmits power to the driven pulley, which in turn drives the driven shaft and connected mechanical components. During transmission, the belt tension affects the magnitude of friction. Too low a tension leads to slippage, while too high a tension increases the load on the shaft and bearings. Therefore, the tensioning device needs to be adjusted periodically.

[0003] Oil pumping units are typically equipped with pulleys. Most current pulleys transmit power through friction between the belt and the pulley, which generates a significant amount of heat during operation. Over time, this heat accumulates and can damage the pulleys. Furthermore, most current pulleys have poor heat dissipation capabilities, making them impractical. Therefore, to address these issues, we propose an oil pumping unit pulley with faster heat dissipation. Utility Model Content

[0004] The present invention mainly addresses the technical problems existing in the prior art by providing a fast-dissipating oil pump pulley.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fast-dissipating oil pump pulley, comprising a pulley frame, a support mechanism, a reinforcement mechanism, and a heat-resistant mechanism. The pulley frame is equipped with a heat dissipation mechanism, and a rim is formed on the surface of the pulley frame. The heat dissipation mechanism includes a groove, and an aluminum alloy sheet is fixedly connected inside the rim. A heat dissipation fin is fixedly connected to the inner side of one side of the aluminum alloy sheet. The heat dissipation fin is disposed inside the groove. A heat dissipation hole is formed through the interior of the pulley frame. One end of one or more fins of the heat dissipation fin extends from the groove. Several grooves and several heat dissipation holes are formed.

[0006] Preferably, the wheel rim has two rims located on both sides inside the wheel frame. The two rims can support two belts for transmission. The double-rim structure can significantly reduce the risk of belt slippage and ensure the continuous and stable operation of the transmission system.

[0007] Preferably, the slot is formed inside the wheel frame, the slot communicates with the wheel rim, and there are several slots, corresponding to several aluminum alloy sheets, which cover the slots.

[0008] Preferably, the support mechanism includes an axle, with a hub inside the axle and spokes fixedly connected to the outer side of the axle. The spokes are fixedly connected to a wheel frame, and a plurality of spokes are provided, the portion connecting the wheel rim and the hub serving to support and transmit torque.

[0009] Preferably, the reinforcement mechanism includes reinforcing ribs, which are fixedly connected between the wheel frame and the wheel axle. Several reinforcing ribs are provided, and the reinforcement components are fixed at both ends between the wheel frame and the wheel axle.

[0010] Preferably, the heat-resistant mechanism includes a ceramic sheet, which is fixedly connected to the outside of the wheel frame. A tin foil is fixedly connected to the outside of the ceramic sheet. Several ceramic sheets are provided, and the tin foil is located on the outside of the fixing member. The surface can efficiently reflect light, thereby reflecting heat.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model, through the setting of the heat dissipation mechanism, has heat dissipation holes arranged in a regular pattern, forming a three-dimensional heat dissipation network with the slot and the rim. When the pulley generates heat during operation, the aluminum alloy sheet 4, with its high thermal conductivity of about 200-240 W / (m·K), quickly absorbs the heat near the rim 2 and conducts it to the heat dissipation fins 5. The aluminum alloy sheet and the heat dissipation fins, through the high thermal conductivity material and the increased heat dissipation area, quickly dissipate the heat near the rim. The slot and the heat dissipation holes form an air convection channel, accelerating heat dissipation. For example, after the aluminum alloy sheet conducts heat to the fins, when the air flows through the slot and the heat dissipation holes, it can carry away about most of the heat on the surface of the fins, making the pulley frame temperature lower than that of traditional pulleys.

[0019] 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.

[0020] Please see Figure 1-4 A fast-dissipating oil pump pulley includes a pulley frame 1, a support mechanism, a reinforcement mechanism, and a heat-resistant mechanism. The pulley frame 1 is equipped with a heat dissipation mechanism, and a rim 2 is formed on its surface. The heat dissipation mechanism includes a slot 3. An aluminum alloy sheet 4 is fixedly connected inside the rim 2. A heat dissipation fin 5 is fixedly connected to the inner side of one side of the aluminum alloy sheet 4. The heat dissipation fin 5 is located inside the slot 3. A heat dissipation hole 6 is formed through the interior of the pulley frame 1. There are two rims 2, located on both sides inside the pulley frame 1. The slot 3 is formed inside the pulley frame 1 and communicates with the rims 2. Two rims 2 are formed on the surface of the pulley frame 1. An aluminum alloy sheet 4 is fixed inside the rim, and the heat dissipation fin 5 connected to its inner side extends into the slot 3. The slot communicates with the rim. Several slots correspond to several aluminum alloy sheets. One end of the fin extends outward from the slot. The heat dissipation hole is formed through the interior of the pulley frame. The aluminum alloy sheets 6 are arranged in a regular pattern, forming a three-dimensional heat dissipation network with the slots and rims. When the pulley generates heat, the aluminum alloy sheets 4, with their high thermal conductivity of approximately 200-240 W / (m·K), quickly absorb the heat near the rim 2 and conduct it to the heat dissipation fins 5. The fins enhance air convection by increasing their surface area, such as fin height of 5-10 mm and spacing of 10-20 mm. At the same time, the heat dissipation holes 6 allow airflow to pass through the wheel frame, forming a "chimney effect" and accelerating heat dissipation. The aluminum alloy sheets 4 and heat dissipation fins 5, through the high thermal conductivity material and increased heat dissipation area, quickly conduct heat away from the rim 2. The slots 3 and heat dissipation holes 6 form an air convection channel, accelerating heat dissipation. For example, after the aluminum alloy sheets conduct heat to the fins, when the air flows through the slots and heat dissipation holes, it can carry away most of the heat from the fin surface, making the wheel frame temperature lower than that of a traditional pulley.

[0021] In one aspect of this embodiment, the support mechanism includes a wheel axle 7, with a hub 8 inside for mounting the axle, and a plurality of spokes 9 on the outside for fixed connection to a wheel frame 1. The spokes have a spoke-like structure, which reduces solid material while transmitting torque and provides space for heat dissipation holes 6.

[0022] In one aspect of this embodiment, the reinforcing ribs 10 of the reinforcing mechanism are fixed at both ends between the wheel frame and the wheel axle, and are distributed in a triangular pattern to enhance the connection rigidity between the wheel frame and the wheel axle, prevent the structural strength from being weakened by the heat dissipation holes, and ensure the stability of the pulley at high speeds; while enhancing the structural strength, the reinforcing ribs 10 do not obstruct the heat dissipation airflow, ensuring a balance between heat dissipation efficiency and mechanical performance.

[0023] In one aspect of this embodiment, the heat-resistant mechanism consists of several ceramic sheets 11 and tin foil 12. The ceramic sheets are fixed to the outside of the wheel frame, and their low thermal conductivity (e.g., the thermal conductivity of alumina ceramic is about 20 W / (m·K)) forms a heat insulation layer, blocking the heat conduction of the external high-temperature environment to the wheel frame. The tin foil 12 covers the outside of the ceramic sheets, and uses the high reflectivity of metallic tin (thermal radiation reflectivity > 80%) to reflect external heat sources (such as sunlight, heat radiation from equipment operation) away, reducing the heat absorption of the pulley. Together with the heat dissipation mechanism, it achieves the heat-resistant effect of "internal dissipation and external resistance". The ceramic sheets 11 block the external heat from entering the wheel frame, and the tin foil 12 reflects heat radiation, reducing the absorption of external heat by about 30%, avoiding "external heat transfer to the inside" which aggravates the internal temperature rise, and is especially suitable for high-temperature environments in oil fields.

[0024] The working principle of this utility model is as follows: During operation, this fast-dissipating oil pump pulley achieves efficient heat dissipation through the synergistic effect of its heat dissipation mechanism, heat-resistant mechanism, and structural design, solving the problem of heat accumulation and damage caused by traditional pulleys. During operation, the heat generated by the pulley's rotation is first absorbed by the aluminum alloy sheet 4 and the heat dissipation fins 5. The high thermal conductivity of the aluminum alloy rapidly conducts the heat to the fin surface. The fins then contact the outside air through the slots 3, utilizing air convection for heat dissipation. Simultaneously, the heat dissipation holes 6 inside the pulley frame 1 form a through-flow channel, accelerating heat dissipation. The ceramic sheet 11 in the heat-resistant mechanism uses its low thermal conductivity to block external heat from being conducted to the pulley frame, while the tin foil 12 reflects external heat radiation through its reflective properties, reducing heat absorption. The double-rim design 2, while stabilizing the belt drive, further enhances the heat dissipation area in conjunction with the aluminum alloy sheet, ultimately achieving rapid heat dissipation and isolation, ensuring the pulley remains at a low temperature during long-term operation.

[0025] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
