DETAILED DESCRIPTION

[0019] In order to enable personnel in the technical field to better understand the technical scheme of the present application, the technical scheme in the embodiments of the present application will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor should belong to the protection scope of the present application.

[0020] As shown in the accompanying Figure 1 to the accompanying Figure 4 drawings.

[0021] The high-performance high-strength clutch pulley provided by the present application comprises a pulley 1, a wheel body reinforcing structure 2, an expansion seat 3, a compressor 4 and a transmission belt 5, wherein: the pulley 1 is fixedly installed on the input shaft of the compressor 4, and the wheel body reinforcing structure 2 is rotatably installed on the outer side of the pulley 1, and the expansion seat 3 is fixedly installed on one side of the compressor 4; the expansion seat 3 is fixedly connected with the other end of the wheel body reinforcing structure 2; and the transmission belt 5 is engaged on the outer side of the pulley 1.

[0022] The pulley 1 comprises a pulley rim 11, a belt positioning groove 12, a clutch friction pressing piece 13 and a support extension shaft 14, and the pulley rim 11 is fixedly installed on the input shaft of the compressor 4, and the belt positioning groove 12 is arranged on the outer side of the pulley rim 11; the outer side of the belt positioning groove 12 is engaged with the transmission belt 5; the clutch friction pressing piece 13 is fixedly installed on the pulley rim 11, and the support extension shaft 14 is fixedly installed on the surface of the clutch friction pressing piece 13, and the support extension shaft 14 is rotatably connected with the wheel body reinforcing structure 2.

[0023] The wheel body reinforcing structure 2 comprises a protective shell plate 21, a docking rotary seat 22, a support framework 23, a belt positioning wheel 24 and a mounting base 25, and the docking rotary seat 22 is installed at the middle position of the protective shell plate 21, and the docking rotary seat 22 is rotatably installed on the support extension shaft 14; one end of the support framework 23 is fixedly installed on the outer side of the protective shell plate 21, and the other end of the support framework 23 is fixedly installed on the expansion seat 3 through the mounting base 25; and the belt positioning wheel 24 is rotatably installed in the support framework 23 and is in contact with the outer surface of the transmission belt 5.

[0024] The pulley 1 is made of HT150 gray cast iron, and the outer surface of the belt positioning groove 12 is wrapped with a layer of carbon steel shell. The belt rim 11 can move by controlling the electromagnetic clutch friction pressing piece 13 inside. The supporting extension shaft 14 is a metal structure that protrudes outward, and can move with the clutch friction pressing piece 13. When the clutch friction pressing piece 13 is not combined with the belt rim 11, the engine only drives the pulley 1 to rotate. When the clutch friction pressing piece 13 is combined with the belt rim 11, the engine can drive the pulley 1 and the shaft of the compressor 4 to rotate simultaneously.

[0025] The protective shell plate 21 inside the wheel body reinforcing structure 2 is made of an aluminum plate, and the size of the protective shell plate 21 matches the pulley 1. The protective shell plate 21 is supported by the butt joint rotating seat 22 and keeps a gap with the pulley 1. The belt positioning wheel 24 is made of two metal wheels, and is in contact with the transmission belt 5 and is passively rotated by the movement of the transmission belt 5.

[0026] Compared with the prior art, the device has the following advantages:

[0027] 1. Stronger structural strength and stability

[0028] The wheel body reinforcing structure 2 enhances the structural strength of the pulley 1 through the protective shell plate 21, the support framework 23, the installation base 25 and other components, effectively disperses the transmitted load, and avoids deformation or damage of the pulley caused by excessive pressure, which enables the device to withstand higher loads and maintain stability in long-term operation.

[0029] Compared with traditional pulleys, the prior art may use a simpler structure and lack sufficient reinforcement design, which is easily affected by external impact or load changes, resulting in instability or damage of the device.

[0030] 2. Excellent clutch control function

[0031] The electromagnetic control clutch friction pressing piece 13 in the device can realize precise clutching function through the electromagnetic control of the belt rim 11, and its clutching process is smoother and more reliable, avoiding the possible sliding or impact of traditional clutches, and providing more efficient power switching.

[0032] In traditional systems, clutches are usually controlled by mechanical means, which may have incomplete clutching or inaccurate operation problems.

[0033] 3. Higher power transmission efficiency

[0034] Due to the precise fit between the pulley 1 and the belt positioning wheel 24, the system ensures that the transmission belt 5 is always in optimal engagement, avoiding power loss due to belt slackness or slippage, resulting in higher transmission efficiency and effective reduction of energy waste.

[0035] Compared to the potential belt slackness or poor engagement in existing technologies, this device provides more stable and efficient power transmission.

[0036] 4. Better wear resistance and high-temperature resistance

[0037] The device uses high-strength materials and optimizes the design for wear problems between the transmission belt 5 and the pulley 1. The pulley rim 11 is wrapped with a carbon steel shell, effectively improving wear resistance and high-temperature resistance, prolonging the service life of the system.

[0038] In existing technologies, many devices are prone to wear under high load or high temperature, leading to frequent maintenance or shortened system life.

[0039] 5. Higher safety

[0040] The protective shell plate 21 and the wheel body reinforcement structure 2 provide an additional protective layer for the pulley 1, reducing potential safety hazards caused by external impacts or system failures. The entire device structure is more robust, effectively preventing internal damage and leakage.

[0041] In contrast, the pulley system in existing technologies may lack sufficient protection, making the device vulnerable to damage and even causing safety accidents.

[0042] 6. More flexible angle adjustment and motion control

[0043] The device uses a rotatably connected support extension shaft 14 and a docking rotary seat 22, providing more flexible motion control capabilities, allowing the pulley 1 to adjust its angle according to work requirements to adapt to different working conditions.

[0044] Traditional pulley systems often lack this flexible adjustment function and usually require additional equipment for angle control.

[0045] 7. Easy maintenance and longer service life

[0046] The design of this device takes into account the reliability and maintainability of long-term operation. Due to its robust structure and the use of high-strength materials, the device can still work stably for a long time under high load, reducing the frequency of maintenance and replacement of parts.

[0047] Compared to traditional technology, existing devices may require more frequent maintenance and replacement of parts, increasing operating costs.

[0048] Summary:

[0049] Compared with the prior art, the device has significant improvements in structural strength, clutch control accuracy, power transmission efficiency, wear resistance, safety and flexibility, etc., which makes the device provide more stable, efficient and safe performance in high-strength and high-load application environment, thereby showing longer service life and lower maintenance cost in actual application.

[0050] The technical scheme disclosed by the utility model, or the technical scheme designed by the person skilled in the art inspired by the technical scheme of the utility model, achieves the above technical effects, and falls within the protection scope of the utility model.
